 Buying a new boiler is one of the most important decisions you’ll make as a homeowner. The right boiler can keep your home warm and efficient for 15+ years, but making the wrong choice can lead to inefficiency, higher energy bills, and even costly breakdowns. At Fix First Heating, we’ve seen it all – and we want to help you avoid the most common (and expensive) pitfalls. 1. Oversizing the BoilerBigger is not always better. Many people assume a larger boiler will perform better, but an oversized boiler can actually be less efficient. It delivers more energy than your home needs, resulting in wasted fuel, inconsistent heating, and higher bills. Fix First Tip: Always request a detailed heat loss survey to ensure correct sizing. Avoid installers who “guess” based on bedrooms or bathrooms. 2. Choosing a Poor-Quality BrandNot all boilers are created equal. Cheap brands like Ferroli or Biasi might save money upfront but can be unreliable and difficult to maintain. You may find yourself stuck with costly repairs and limited aftercare. Fix First Tip: Stick with proven, reliable brands like Worcester Bosch, Vaillant, or Atag. These may cost more initially but will save you stress (and money) in the long run. 3. Prioritising Price Over QualityEveryone loves a bargain – but going for the cheapest quote often means cutting corners. A low-cost installation might skip important steps like system flushing or fitting high-efficiency controls. Fix First Tip: Focus on value, not just price. Get quotes from multiple reputable companies and compare what’s included. If it seems too good to be true, it probably is. 4. Choosing the Wrong InstallerThe best boiler in the world won’t help if it’s installed poorly. An unqualified or inexperienced installer can cause serious issues – from water leaks to reduced system lifespan. Fix First Tip: Choose a Gas Safe registered installer with strong local reviews. Ask about their experience, qualifications, and what’s included in their installation process. 5. Installing a Boiler Unsuitable for the Property TypeThe wrong type of boiler can cause pressure issues, limited hot water, or inefficient heating. For example, a combi boiler might struggle in a large home with multiple bathrooms. Fix First Tip: Understand the differences between combi, system, and heat-only boilers, and choose what suits your home layout and usage. 6. Ignoring After-Care and ServicingA 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. 7. Underestimating Future Maintenance CostsSome boilers are more expensive to repair than others, especially if parts are rare or the manufacturer has a poor support network. Fix First Tip: Research maintenance and parts availability before choosing a boiler brand. Talk to your installer about expected running costs over the next 10-15 years. 8. Not Considering Smart ControlsModern 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. 9. Skipping a System FlushInstalling a new boiler on a dirty system can drastically reduce its life. Many installers skip or skimp on the system flush to lower the price. Fix First Tip: Insist on a proper chemical cleanse, Thoroughflush, or powerflush, depending on your system’s condition. It’s a crucial step for long-term performance. 10. Not Getting a Second OpinionSome salespeople push specific brands or setups to earn commission. Relying on just one quote can limit your options and lead to biased advice. Fix First Tip: Always get at least two or three quotes. Ask why a certain boiler is being recommended and whether there are alternatives that better suit your needs. 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.
