Common Mistakes to Avoid During New Boiler Installations

When it comes to new boiler installations, it's essential to get things right the first time. Even small oversights or errors can lead to significant complications down the line, including inefficient operation, higher energy bills, and even potential safety risks. Whether you're a homeowner looking to manage your installation or a professional installer seeking to perfect your practice, avoiding common mistakes is crucial. Below, we explore some of the most prevalent pitfalls to sidestep during new boiler installations.

Choosing the Wrong Boiler Size

The boiler size, also known as its output, directly impacts its ability to meet your home's heating and hot water demand. A boiler that's too small won't provide sufficient heat, while one that's too large can lead to wasted energy and inflated bills. It's critical to consult a certified professional who can carry out a comprehensive heat loss survey of your property to determine the most suitable boiler size.

Ignoring Efficiency Ratings

While a cheaper, less efficient boiler might seem appealing due to its lower upfront cost, it's crucial to consider the long-term implications. More efficient boilers use less fuel to produce the same amount of heat, leading to lower energy bills over time. They're also more eco-friendly. When choosing your new boiler, ensure you look out for the energy efficiency rating, often expressed as a percentage or as an A-G rating.

Skipping Regular Maintenance

Even after successful installation, it's essential to schedule regular maintenance checks for your boiler. These checks help identify and rectify any minor issues before they evolve into significant problems that could necessitate expensive repairs or even total replacement. It's advisable to have your boiler serviced annually by a certified professional to maintain optimal performance.


Overlooking System Compatibility 

Every home heating system has its unique characteristics and requirements, from the piping and radiators to the hot water cylinder and thermostat controls. Failing to ensure your new boiler is compatible with these existing components can result in a mismatched system that doesn't work as efficiently as it should. Always consider the overall heating system and consult a professional to verify compatibility.

DIY Installation

Whilst it may be tempting to save money by installing the boiler yourself, this can lead to significant problems down the line. Installing a boiler is a complex task that requires professional knowledge and skill to ensure safety and compliance with building regulations. Always rely on a certified and experienced professional for your new boiler installation.
