Replacement gas boiler

Boilers account for 60% of our home’s energy bills, so it’s important to ensure your system is working efficiently and won’t encounter any problems down the line.

Gas boilers can breakdown or fault at any time, leaving you without heat or hot water until the problem can be fixed. And unfortunately there is never any warning of when an old boiler will breakdown.

Boilers over 10-years-old are more prone to problems and repair bills can exceed £300. Given you could be saving money every year on energy bills and limit the risk of a breakdown, a replacement gas boiler could be your answer.

Benefits of a gas boiler replacement

Gas boilers are at the heart of your home, providing you with heat and hot water all year round. This makes a breakdown even harder for the general dynamics of your property.

With a replacement boiler:

  • Reduce your heating bills by as much as £300 a year. Inefficient boilers could be working at just 70%, meaning you’re paying out a lot more annually than you should be. Efficient condensing boilers burn fuel more efficiently, producing a greater amount of heat.

  • Cut your home’s carbon footprint by up to 1,220kg a year, helping the environment with global warming problems and aiding the Government in meeting EU targets.

  • Heat your home more efficiently and ensure heat is distributed evenly. When a new boiler is installed you’ll often receive other services such as a power flush to remove sludge build-up.

Combi boilers

Combi boilers or combination boilers are the UK’s most popular replacement gas boiler installation, with over 50% of new systems being a combi.

Combi gas boilers are highly efficient condensing boilers, converting more fuel into usable heat. This is made possible with a larger flue, which captures more of the hot gases and prevents them from escaping.

Combi boilers are also popular because they provide homeowners with hot water on demand, scrapping the need for water tanks in the loft or airing cupboard. This also means you’ll save plenty of room in your home.

Energy Performance of Houses

Homes are given an energy ranking dependent on how efficient they are and ratings are shown in the data underneath. This ranges from A, the most energy efficient, to G, the very least efficient. With a higher rating you're more likely to have less expensive energy bills as more heat will likely be retained in the home. You are able to increase your home's efficiency with insulation including upvc double glazing, loft lagging or wall cavity insulation.
