Heating accounts for approximately 60 % of the items you may spend each year on energy bills, so an cost-efficient boiler makes an important difference.
Modern boilers tend to be extremely effective for several reasons, however their key advantage is that they are all condensing boilers. All well-managed boilers burn their fuel very efficiently, yet they unavoidably waste some energy from the hot gases which escape the flue. A condensing boiler comes with a bigger heat exchanger, so that it recovers more heat, sends cooler gases in the flue and it is more effective.

Sometimes the flue gases end up receiving so cool which the water vapour within the gas condenses out (hence the name), and much more energy is reclaimed coming from the condensing vapour.

When you replace your boiler you can actually invest in a new regular boiler, whilst keeping your boiling water cylinder, or purchase a combi boiler that doesn't need to have a cylinder.
A regular boiler is actually reliable compared to a combi at producing domestic hot water from the start, however some heat is lost from your very hot water cylinder, so a combi could be more cost-efficient overall.
