Replacement boilers

Replacing with a more efficient boiler

One of the main distinctions between boilers is whether they are condensing or not. Old boilers tend to be non-condensing, but all new models are. You can check the efficiency of your old boiler by using the Product Characteristics Data Base at https://www.ncm-pcdb.org.uk/sap/

As a general rule, if your boiler is non-condensing it is probably worth replacing, either with a heat pump or with a more efficient condensing boiler.

This would be worth you getting more advice on to decide which option to take. More general information can be found here: https://energysavingtrust.org.uk/advice/boilers/
