Whilst exchanging a worn out boiler with a new one without doubt hits the bank balance, there are also numerous benefits to upgrading your central heating system, particularly if you don’t currently have TRVs (Thermostatic Radiator Valves) or a room thermostat on your system.
Improved boiler efficiency
The energy saving trust estimates that a central heating boiler is liable for 60% of your home energy bills, so having a more efficient boiler can make a sizeable difference to your bills. Most new condensing boilers are A rated which means their efficiency is 90% or even more. The efficiency of your old boiler is dependent upon a number of factors but typically an old non-condensing boiler would be G rated meaning it is less than 70% efficient and could well be 55% -70% efficient. Depending on your gas bill, moving to a far more efficient condensing boiler could save £200-300 annually. See the energysavingtrust.org.uk website for additional information.
Improved heating control
Using a heating controller with TRVs and a room thermostat means that you can set the temperature in each room independently. Each TRV shuts off its radiator from the heating when the air around the valve reaches the desired temperature. In general people want sleeping areas to be about 2 degrees C cooler than living areas so by using TRVs can improve comfort levels. Once each room is at the desired temperature and all the TRVs have shut down their radiators then a room thermostat, placed near one radiator without a TRV, can switch the entire boiler system off. This saves cash as well as keeping the temperature at the right level.
Quieter boiler function
Due to improved design and much better use of materials, brand-new boilers can be significantly quieter than older type boilers. This can make a real difference where a boiler is sited the other side of a bedroom wall.
Modern boilers are generally smaller than their older counterparts and there are more options for siting them on walls in lieu of floors. They can even be concealed behind a kitchen cupboard. This may free up useful space for a lot of property owners.
