There are a number of factors to consider when buying a combi boiler. Price might be your first consideration. As with other consumer purchases, compromising on quality to reduce the initial cost may mean paying a price later in repairs and inconvenience. Cheap boilers are often difficult to repair and hard to find parts for, which means heating engineers may be reluctant to work on them.

Long-Term Peace of Mind
Long-term peace of mind is important to most boiler buyers. Some boilers offer up to 14 years of parts and labour warranty, meaning that if the boiler goes wrong, the manufacturer will fix it for free.

Minimum Heating Output
Another factor to consider is the minimum heating output. This means that the boiler can be adjusted to match the size of the heating system in your house. A combi boiler with a hot water output of 30 kW doesn’t need to work hard to heat your radiators. By lowering the heating output to match the size of your system, you will be wasting less energy. If your boiler’s minimum heating output can only be lowered to 10 kW, you’ll probably be burning more gas than necessary. The lower this number is, the more efficient your boiler.

Hot Water Flow Rate
We also mention hot water flow rate, which is important when choosing your new combi boiler. Generally speaking, the higher the hot water output in kilowatts, the better the flow rate will be.

A boiler is a long-term investment – and it needs regular care. Many homeowners forget to check what after-care is included, or skip servicing altogether.
​
Fix First Tip:
Choose an installer that offers ongoing support, annual servicing, and extended warranties. Ask if they offer service plans or maintenance contracts.

Modern boilers paired with smart controls can significantly improve efficiency and comfort. But many people stick with basic thermostats or don’t install proper heating controls at all.
​
Fix First Tip:
Invest in smart or OpenTherm-compatible controls. Options like Nest or Hive offer flexible programming and remote control – but check if they’re compatible with your boiler for full efficiency benefits.

Buying a new boiler doesn’t have to be overwhelming. By avoiding these common mistakes and asking the right questions, you can make a smart, informed choice that keeps your home warm, safe, and efficient for years to come.

At Fix First Heating, we believe in clear advice, honest pricing, and long-term customer care. If you’re ready to explore your options – or just want to ask a few questions – we’re here to help.

Why we champion the use of suppliers owned and run by the people of Peterborough.
​
For Fix First Heating, supporting our community is the heartbeat of our business. As a trusted heating company serving homes and across our region, we know that every purchasing decision we make has the potential to strengthen the local economy and build a more prosperous future for everyone.

That’s why, at Fix First, we prioritise the use of local businesses. We buy our boiler parts and plumbing materials from smaller, independent merchants. Our marketing and office supplies are bought from nearby suppliers. We are proud members of BNI, an active network of 50 + business owners from around our local area.
​
In this blog, we’ll demonstrate how Fix First Heating puts local businesses first: why we choose family-run, independent suppliers over multinational companies, how this decision benefits our customers and our community, and how our BNI membership enables us to support and collaborate with other local enterprises.

When you think of heating, you might picture boilers and radiators, but at Fix First, we see heating as something far greater: a vital service that brings warmth, comfort, and security to families, schools, and businesses. Every project we undertake is rooted in relationships, with our customers, our team, and the wider community.

One of the most profound ways we nurture these relationships is by supporting independent, locally owned businesses. In today’s globalised world, it’s often more convenient to buy from a massive international company, with their vast stocks, and streamlined logistics. But what’s the real cost of choosing these corporate giants over family-run suppliers right here in our region?
​
The answer is clear to us at Fix First: local suppliers are the backbone of our community. By investing in them, we help create jobs, stimulate the local economy, and retain wealth within our area. When £1 is spent in our local community, it stays in the local community. It’s not used to boost the portfolio of international investors. We believe that when local businesses succeed, we all benefit.

At Fix First Heating, most of our suppliers are local, family-owned businesses. From the copper pipes and boilers, to leaflet printing and graphic design, we source as much as possible from independents who are invested in our community’s future.

Here’s what that looks like in practice:
​

• Personal Relationships: We know our suppliers by name. We visit their premises, shake their hands, and exchange stories about our families and our plans for the future. These aren’t faceless corporations; they’re our neighbours, friends, and partners.
• Reliability and Accountability: Family-owned businesses depend on their reputation. When we work with local suppliers, we know we’re getting more than just the product. We’re getting quality, service, and accountability. If an issue arises, there’s no call centre halfway around the world; there’s a direct line to someone who genuinely cares.
• Quality and Craftsmanship: Local suppliers take pride in their products because their name is on the line. This pride translates into better materials, superior craftsmanship, and greater attention to detail. Our customers benefit from the kind of quality that only a close-knit, dedicated team can deliver.
• Unique Solutions: Multinational corporations might offer one-size-fits-all solutions, but local businesses are nimble and responsive. Our suppliers understand the distinct challenges of our region and can adapt to our needs, ensuring we always have the right materials and support for any project, no matter how unique.
• Keeping Money in the Community: Every pound we spend with a local business circulates within our economy, creating jobs, boosting public services, and helping other small businesses. By working with local organisations, we are contributing thriving community.

Let’s be clear: multinational corporations have their place in the modern economy. They can offer scale, consistency, and sometimes lower prices. But at what cost?

If we don’t use our local suppliers, they could disappear from our high streets and industrial areas, to be replaced by faceless multinationals with no interest in the preservation of local communities.

When local merchants are bought out by multinational companies, the priorities often shift away from the community. Decision-making moves to distant head offices. Jobs are consolidated or lost. Profits are extracted and sent far away, instead of being reinvested locally. The unique character of our high streets fades, replaced by a sea of identical brands.
​
At Fix First Heating, we believe there’s a better way. By choosing local, family-owned businesses as our primary suppliers, we keep our region vibrant, diverse, and resilient. We maintain real relationships, and we know that our success is intertwined with the success of our partners.

 We use a number of local merchants to supply our boilers, spare parts, heating components and plumbing materials. These are our first choice for all heating projects:
 
PHC Supplies

PHC Supplies are a local, independently run business, priding themselves on their excellent reputation and customer service.

Loss of pressure on your boiler or heating system has only one cause: you have a leak.

The regularity of the pressure loss indicates the size of the leak. If you’re topping your pressure up hourly, the leak is significant. If it’s only every few weeks, it’s minimal.
​
You can increase the pressure yourself on your boiler or heating system. But, if you have to do this regularly, there’s a problem that needs attention.

​A pressurised heating system has to be maintained at between 1-1.5 bar. If the pressure drops too low, it affects the performance of your heating.

You may find any of the following symptoms:

• The radiators don’t heat up properly: perhaps they are cold at the top, don’t heat up at all, or they are cooler than usual.
• The system may become louder as your heating pump may be struggling to circulate water effectively.
• The boiler may lock itself out and display a fault code.
• You may notice the boiler turning itself off and on more often than usual. This is called cycling and is caused by poor water flow through the boiler’s heat exchanger.

In this video we demonstrate how to put more pressure into your heating system using the filling taps below the boiler.

The pressure should sit between 1 – 1.5 bar. If the pressure falls below 1 bar, it needs topping up. If the pressure has risen above 2 bar, that’s a different issue that needs looking at.

The pressure is increased by putting water from your mains cold water pipe into the heating circuit. This is done from a filling device that will usually be in the airing cupboard or just below your boiler.

Combi boilers tend to have built-in filling devices. You should find the taps below the boiler on the right-hand side. There will be two taps that need to be gently opened up until the pressure returns to a normal level.

Each boiler has its own type of filling device. Check out our help videos for your boiler manufacturer: Ideal and Baxi/Potterton

On a system with a hot water cylinder, you’ll most likely find the filling loop in the airing cupboard. This will be a flexible braided silver hose between two valves that both need to be opened to pass mains water into the heating system.

Once or twice a year is about normal. If you’re doing it more often than this, especially during the winter months, when your heating is getting used often, then the boiler may need attention.

If you have to re-pressurise your boiler every day during the winter months, you probably have a deflated expansion vessel.

The pressure in your heating is regulated by a tank of compressed air somewhere on the system. Just like a car tyre, this needs regularly checking for the correct pressure. If the expansion vessel is empty, the pressure in your heating will start to fluctuate.

The pressure will rise as the water heats. If it gets to 3 bar, a safety valve opens, dumping pressure to a safe location. Once the water cools and contracts, the pressure will drop as low as 0 bar.
​
Continuing to top your pressure up without dealing with the fault will cause damage to your system. Constantly adding fresh, oxygenated water into radiators will cause rust and corrosion. Get the help of a heating engineer as soon as possible if you are experiencing this problem.

Usually, a leak is easy to find. Stains on carpets of flooring will be an obvious sign. There may be a leak on one of your radiators or the valves that connect to it.

Before calling a heating engineer, check all the radiators in your house for signs of rust or staining. Look under and around your boiler to see if there are any connections becoming scaled or grimy.

It’s also worth checking outside your house for the pressure-relief pipe. If this is dripping it could go unnoticed, especially if it’s located somewhere inconspicuous.

Components inside the boiler that commonly leak are the pressure relief valve or automatic air vent. These can be easily changed by a qualified heating engineer.

In some case the leak is on the heating pipework. This may be visible pipework leading to radiators, or hidden behind walls or above ceilings.
​
When heating pipework runs under solid floors, this can be expensive and very disruptive to repair. Your heating engineer may advise you to seek advice from a specialist leak detection company and to consult your insurance company.

If the leak is small and inaccessible, your heating engineer may recommend adding a leak sealing solution, such as Fernox F4, into the system. This uses a chemical to seal pinholes in the heating pipework without causing blockages.

When the leak is visible it can be repaired by replacing the faulty component. This might mean replacing a radiator valve, a boiler component, or renewing a section of your heating pipework.

It’s a good idea to seek help from your local reputable heating company before the problem gets worse.

Can’t find the leak on your system or struggling to get the help you need to fix it?

Ask your question in the box below and we’ll get back to you with our advice.

We’ve fixed heating in Peterborough for many years and know how to diagnose a fault on your boiler.

Often, your boiler will give you information about the problem. Some boilers have display screens which give you a fault code. By looking in the manufacturer literature, you can determine the nature of the fault.

For example, an Ideal Logic boiler showing the code L2, as shown in the video, has an ignition problem. This could be caused by an interruption in the gas supply, a faulty gas valve, broken ignition electrodes or a blocked condensate trap.

Other boilers indicate their faults by flashing lights in different sequences. A Worcester Ri uses its own form of morse code, flashing fast or slow to communicate the problem.

Your boiler may have locked out because there is no circulation in your heating system. If your heating pump has failed, the boiler may overheat, or turn itself off because its temperature sensor readings are not as expected. Many Glowworm and Vaillant boilers show a fault of F22 if there is poor circulation. This may be caused by a faulty circulator pump, some sort of restriction or blockage in the heating pipes, or an airlock.

Sometimes your boiler will indicate it has a problem with a particular component. If an electrical component has failed, such as the PCB (Printed Circuit Board) the boiler sometimes behaves in unusual ways, maybe running the fan sporadically or repeatedly trying to light the burner. A faulty circuit board on the Glowworm xi range often appears as a blank display screen.

On older boilers without these sophisticated diagnostic systems, a fault is determined by following the ignition sequence. This sequence usually starts with running the fan. If you don’t hear the fan running, or if you can hear a grinding or buzzing noise, the fan may have burned out and needs replacing.

You can do some basic fault finding yourself by checking the boiler for faults and noises. If you have an ignition problem, first check other gas appliances in your house to ensure your gas supply is working. You can even fix some problems yourself in some cases without calling out a heating engineer. If your boiler is showing a low pressure fault, all you need to do is top the pressure up. There will be a filling device on or near your boiler, or in your airing cupboard. You can often reset the boiler to get it going again. It’s a good idea to record the fault code first, as this information is useful for your heating engineer when diagnosing the fault.

You must never work on your own boiler unless you are qualified. However, having some background information on fault codes, noise or strange behaviour on your boiler will be useful when you call your local qualified heating engineers.

There are 3 basic types of boiler, which are available in gas or oil:

Combi boiler – directly heats both your heating and hot water

Heat only boiler – just heats the water to be supplied to your radiators and the hot water cylinder in your airing cupboard.
​
System boiler – similar to a heat only, but it contains the circulator pump within the boiler. It also allows for the small header tank in your loft to be removed.

Your house will have a certain amount of heat loss. Your system and boiler should match this rating to ensure they work most efficiently. Oversized boilers are inefficient as they deliver too much energy for the size of the system. Undersized boilers are ineffective as they won’t give you enough heat to make up for your house’s heat loss.

Ideally you should have a detailed heat loss survey on your house to ensure you’ve sized the boiler correctly. This obviously adds to the cost but may save you money in the long run. Most companies just look at the number of bedrooms and bathrooms in your house, then use their judgement on the boiler capacity. This method almost always results in oversizing.

​Boiler output is given in kilowatts. The higher the kilowatt output, the more expensive the boiler will be.

The quality of the boiler is the biggest determining factor in the cost of replacement. You can get some very cheap nasty boilers, which we do not fit and would never recommend. You’re entering a world of pain if you choose to fit a Ferroli, a Biasi, or something similar.

At the high end, you have brands such as Worcester, Vaillant and Atag. These companies have built a reputation for reliability and build quality.

Somewhere in the middle sit brands like Ideal and Baxi. If you’ve bought a new build house in the last 10 years, the chances are, it has an Ideal boiler.

​All boiler manufacturers offer some kind of reward scheme to their installers, so many companies will steer their clients towards their preferred brand. It’s wise to ask the engineer or sales person about other potential options.

You have a choice of 3 here. A full powerflush, a chemical cleanse, or a mains pressure flush.

A proper powerflush will take a full day to complete. It’s unlikely that any boiler quote you receive will include this.

A chemical cleanse is often used when new boilers are fitted. The engineer will add a cleaning chemical to the system and let it run for a while before draining the system to remove the dirty water. This is by far the cheapest option, but doesn’t clean the sludge out of your radiators very effectively,

​A system called Thoroughflush is sometimes used as an alternative to powerflushing. This uses mains-pressure water to clear debris from your system. It can target each radiator individually but takes a fraction of the time of a full powerflush.

Thermostats and programmers vary widely in quality.

Recent regulations require new systems to be fitted with higher efficiency controls. The most efficient controls use a system called OpenTherm. The control communicates the energy demand so the boiler can adjust its gas consumption and water temperature accordingly. These controls can often adjust heat output on the boiler according to outside air temperature, reducing heat demands in spring or autumn when the weather is mild.

With most boiler makes, you have to use the manufacturer’s own controls to benefit from this system.

​Smart thermostats, such as Hive or Google Nest also meet efficiency regulations and can be fitted to all systems. In most cases, they do not connect to your boiler using OpenTherm, so can only tell your boiler to turn on or off, making them less efficient.

Perhaps the hardest decision of all when buying a new boiler.

Most people rely on recommendations from friends and family to choose their installer. You’re more likely to get the personal touch from a local company. It also means that if any issues arise, you’re more likely to speak directly with an engineer. Checking reviews on Google or Facebook will give you a good idea of the reliability of these local companies.

​Some people opt for the perceived safety of a big company like British Gas or BOXT. This gives you the security of a large network of engineers, but the personal touch is lost. Should any problems occur, you’ll be calling a non-technical call centre operative.

​Like all large purchases for your home, choosing the right boiler is a big decision that will affect your home for many years. It’s important to research your options thoroughly and seek expert advice.

The quick answer is that, on average, a boiler will last between 10 and 15 years. But this will depend on various factors, including your usage, the type of boiler you have, water quality, and level of maintenance. With the right level of care, a boiler could last up to 20 years.

It’s easy to take your boiler for granted and only really worry when you have no hot water or the heating fails to come on in the Autumn. So, what elements can affect the lifespan of your boiler?

Three key factors that affect your boiler’s lifespan

1. The type of boiler 
   Different boilers have varying lifespans because of the design and components that can influence their durability. For example, a combi boiler may last between 10 and 12 years, while a conventional boiler could last 15 years or more. A qualified heating engineer can advise you on the best option for your needs.
   
   
2. Regular maintenance
   Regular servicing will identify minor issues before they become bigger and more expensive to fix. The checks undertaken include identifying leaks, ensuring correct pressure, and cleaning components. Boilers serviced by qualified heating engineers tend to last longer. 
   
   
3. Usage and water quality
   Boilers in homes with high hot water demand or those running constantly during the cold months may wear out faster than those in homes with lower demand. Equally, limescale can build up and reduce boiler efficiency in areas with hard water. Installing a water softener can help combat this problem. 

Looking out for these signs can help you when your boiler has an issue or is nearing the end of its life.

Danger signs for the lifespan of your boiler

• When you hear unusual noises coming from your boiler, you may have a problem. These could be banging, clunking or whining, indicating additional pressure being placed on some internal parts, which can be down to wear and tear.
  
  
• You may see signs of leaking or dripping in and around your boiler. Often, this can indicate corrosion or pressure issues, which means your boiler is not running as it should.
  
  
• Maybe you need to call a heating engineer for frequent breakdowns. It is not an ideal situation, and it is often inconvenient. It shows your boiler is struggling and may need a service or replacement.
  
  
• You have increased energy bills. An old or inefficient boiler must work harder to maintain output, meaning higher energy usage.
  
  
• Reduced efficiency. Your boiler is not heating your home or water as effectively as it once did, indicating you have an issue.

Before you get to the stage of experiencing any of these danger signs, there are other ways you can extend the lifespan of your boiler. These are relatively easy to take up, and if you work with a qualified heating engineer, they will be happy to help.

How to extend the lifespan of your boiler

Schedule an annual service with a Gas Safe registered engineer to ensure your boiler lasts as long as possible. Companies such as Fix First Heating offer maintenance packages, which means you can spread the cost of servicing over a year through low-cost monthly payments. It also gives you peace of mind knowing if there is an issue during the year, they will schedule a visit and fix it for you.

Checking your pressure levels on the boiler will help you identify any issues as early as possible. Ask your heating engineer to show you how to do this. Fix First Heating is always happy to do this. Once you know where to look, it’s a relatively easy job. 

Over time, boilers accumulate sludge and debris in the system. If this happens, it can be detrimental to the efficiency of your boiler and, over time, will bring the system to a standstill. Installing a magnet filter is a straightforward way to reduce the build-up of unwanted particles. 

Living in a hard water area can also cause issues with your boiler. Limescale can be deposited in the system and have a similar effect. A water softener will reduce this kind of debris.

Finally, boilers have pipework, which can freeze in the cold winter months. Insulating your pipes can prevent freezing and potentially the damage this can cause. Not least, it can keep your boiler working when you need it most!

When should I consider replacing my boiler?

Sometimes, it just isn’t possible to continue repairing an old boiler. Regular maintenance will extend its life, but most homeowners opt for a replacement after about 15 years. The newer models are very energy efficient, meaning you would save on your energy bills, and the performance would be much more reliable. So, if your boiler breaks down frequently, appears less efficient, or is over 15 years old, investing in a new one may be more cost-effective. 

With the right level of maintenance in place, your boiler can last up to 20 years. Regular servicing and dealing with any minor issues promptly can help ensure your boiler runs efficiently for as long as possible. 

If you’re unsure about the condition of your boiler or worried about breakdowns, get in touch with Fix First Heating. We offer a range of services that will give you peace of mind.

Choosing the right boiler for your house is a big decision. You want your boiler to give you years of reliable service, so getting the right one for your property is important.

As with most other things, you get what you pay for, so its never advisable to go for the cheapest boiler you can find.

We would always recommend choosing from one of the most trusted and renowned manufacturers.

This is a question we get asked a lot. Replacing your boiler is one of the biggest household expenses you’ll have, so it’s wise to consider your options carefully. 

Our website has a quote tool to let you see how much a new boiler will cost, but the truth is, a replacement boiler might not be your best option. 

So, what things should you consider while deciding whether to keep your old boiler running for longer.

Cost of Repair
If your boiler is faulty, the repair might not cost a bomb. Most repairs are less than £300, a fraction of the cost of a new boiler. If it’s a more expensive component, you may decide to cut your losses and replace the boiler. You could ask your engineer to quote for a repair before making your decision.

Age 
Most heating companies will advise you to change your boiler if it’s over 10 years. We don’t agree. If a boiler was fitted after 2005, it’s already A-rated. The efficiency of a boiler doesn’t reduce over time. So, if your gas bills are your primary concern and your boiler is still in good nick, then keep it going.

Efficiency 
Boilers fitted up to the mid-90s will be running at as little as 65% efficiency, meaning you’re wasting 35% of all the heat the boiler produces. After this time, boilers could give efficiency levels of around 80%. Modern condensing boilers claim to run at up to 95% efficiency, but they have to be installed correctly or you could still be wasting energy. We can help adjust your system to make your existing boiler work more efficiently.

Cost of replacement
You could save around £350 a year by replacing an E or F rated boiler with an A rated condensing boiler. So, the cost could potentially be recouped in about 10 years. However, the savings are not as big for D rated boilers, some of which are still in good condition and could potentially keep running for many years if properly looked after by servicing regularly.

Condition of the boiler 
If your boiler has been neglected or has sprung leaks, the cost to repair might be so high that a new boiler with a long warranty would be the better option. If the boiler was cheap and badly installed then a new, reliable boiler is the best option. Again, we’re here to assess your system and give you honest advice. 

Parts
Manufacturers stop making parts for their boilers once the demand for those bits dries up. But, the parts that become obsolete first are the ones that are less likely to fail, meaning the most common parts, such as fans or control boards, may still be replaceable.

Ultimately, the decision is yours. Get in touch and we can give you honest advice to help you make an informed decision.

Have you ever had an engineer come to service your boiler who’s been in and out in 20 minutes?

If you’ve thought to yourself, ‘wow, that was quick’, then the chances are the engineer has not been as thorough as they should.
​
There are a number of key elements to a boiler service, which, if neglected, may cause the boiler to fail when you need it most. This could result in expensive and unnecessary callouts.

So, next time an engineer comes round to do your boiler service, ask them politely if they’ve done the following 5 things:

1. Repressurise your expansion vessel
   The expansion vessel, like your car tyres, needs checking regularly to ensure it’s at the correct pressure. If it isn’t, the water pressure in your heating could rise and fall rapidly, causing corrosion and leaks.
   
   
2. ​Clean the condense trap
   The condensate trap is like the waste under your kitchen sink. If it gets blocked, the water can’t drain away properly. If this happens in your boiler, you’re likely to see a flashing error code resulting in no heat or hot water.
   
   
3. Clean the heat exchanger and burner
   The heat exchanger is where the heat from the burnt gas transfers to the water circulating around your radiators. If this starts to block, the boiler can’t produce enough heat, so your system will take longer to heat up or the hot water will only be luke warm
   
   
4. Clean system filter
   Your system filter collects rust particles that circulate around your system and prevent them from entering the boiler. If this isn’t cleaned every year, it can restrict flow through the system, making it slow to heat up.
   
   
5. Check gas pressure
   The correct gas pressure is vital to ensure the boiler is working properly. Too low and the boiler can’t produce enough heat. Too high the boiler may bang as it lights.
   

All of this should take about an hour or longer if any parts need to be replaced.

Should I Get my Boiler Serviced?
You should expect your boiler to last 15 years or more, but neglecting your annual maintenance may significantly reduce its lifespan. Investing a small amount now on an annual boiler service will prevent expensive bills later for repairs or early replacement. This guide provides essential insights into boiler maintenance, service frequency, and duration.
 
Do I Need to Service My Boiler?
Boilers are a vital part of a comfortable home. When neglected they will develop faults. To keep your boiler in tip-top condition it is essential to get it serviced every year. It is recommended by manufacturers, and warranties often mandate it. Regular services significantly reduce the risk of major breakdowns, saving homeowners from costly repairs.
 
What's the law on boiler servicing?
As a homeowner, you are not legally obliged to service your boiler, but it's highly recommended. If you have tenants in your property, you must have a valid landlords gas safety certificate, which includes safety inspections for all gas appliances.
