If your gas boiler is old or unreliable, it's a good idea to get it replaced with a new, energy efficient model. Not only will a new gas boiler be more reliable, but a new gas boiler installation will give you improved performance and could also lead to huge savings on your heating bills.
Energy Effciency and choosing the Right type of Boiler for you
Older, inefficient gas boilers could be costing you a fortune in heating bills, especially during the winter. The costs can soon add up, as they burn more gas then newer ones. The efficiency of gas boilers is rated from A to G by SEDBUK (Seasonal Efficiency of Domestic Boilers in the UK). A -Rated boilers boast over 90% efficiency, but G-Rated boilers could be as low as 60%. That means for every £1 spent on your gas bills, almost half is wasted straight up the chimney! A gas boiler installation could be an investment in your home and you could really see how the savings add up A new A-Rated boiler could save you as much as £235 off your heating bills year after year.
Always opt for a condensing boiler...
A condensing boiler is a central heating boiler that has improved efficiency over a standard boiler. If your boiler is 15+ years old it could be a G-Rated boiler. G-Rated boilers are the least energy efficient boilers.
You can find out if your boiler is G-Rated by checking the Energy Saving Trust website. Replacing an old G-Rated boiler with a new A-Rated condensing boiler and a full set of heating controls can save up to a quarter on your heating bills straight away. This could be an annual saving of £235 a year.
Decide between combination or conventional boiler...
Installing a combination boiler is certainly a lot easier and cheaper than a conventional boiler, as there is no need for a copper cylinder. So, it also takes up a lot less space. However, we would always recommend a conventional condensing boiler for households with multiple bathrooms and if you require hot water for multiple people at the same time.
A combination boiler is ideal for a 2 to 3 bedroom house or flat with a single bathroom. However a combination boiler's hot water pressure and quality of service is greatly reduced when several different sources require hot water at the same time. For instance the shower pressure and heat can be adversely affected when a hot water tap is switched on or when the washing machine is being used. There is also no possibility of an electric immersion heater with a combination boiler as a backup should the boiler fail.
