Whilst swapping a worn-out boiler with a new one undoubtedly hits the bank balance, there are also several benefits to upgrading your central heating system, particularly if you don’t already 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 accountable for 60% of your household energy bills, so using a more efficient boiler can make a sizeable difference to your bills. Most new condensing boilers are A rated meaning their efficiency is 90% or higher. The efficiency of your old boiler depends on a number of factors but typically an old non-condensing boiler would be G rated meaning it’s 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 per year. See the energysavingtrust.org.uk website for more details.
Improved heating control
Using a heating controller with TRVs and a room thermostat allows you to set the temperature in each room independently. Each TRV shuts off its radiator from the heating when the air around the valve gets to the required temperature. Usually individuals like sleeping areas to be around 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 off their radiators then a room thermostat, positioned near one radiator without a TRV, can switch the entire boiler system off. This saves money in addition to keeping the temperature at the right level.
Quieter boiler operation
On account of improved design and much better use of materials, brand new boilers can be appreciably 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 tend to be smaller than their older counterparts and there are more options for siting them on walls in lieu of floors. They can even be hidden behind a kitchen cupboard. This can free up valuable space for some householders.
