Energy savings
Most newer boilers offer better energy savings, especially if upgrading from an old model that’s not very efficient.
According to the energy saving trust, central heating boilers are responsible for 60 percent of household energy bills. Having a boiler that is more efficient can have a significant impact on your energy bills. The majority of new condensing gas boilers have an A rating, which means they are 90% efficient or higher. An old, non-condensing unit would have a G rating which could mean that it is only 55%-70% efficient.
