Most old gas and oil boilers are regular boilers. They have a separate hot water cylinder to store hot water, rather than providing it directly from the boiler. When you replace your boiler you have a choice of buying a new regular boiler, and keeping your hot water cylinder, or buying a combi boiler that doesn’t need a cylinder.
A regular boiler is more efficient than a combi at producing hot water in the first place, but then some heat is lost from the hot water cylinder, so a combi may be more efficient overall. The best option for you will depend on a number of factors:
How much hot water do you use? A large family using lots of hot water could be better off with a regular boiler. A smaller household using less may be better off with a combi.
Are you short of space? A combi boiler doesn’t need a hot water cylinder, and so needs less space.
Are you thinking of installing solar water heating? Many combi boilers are not compatible with solar water heating or cannot use it so effectively.
We are over the moon with the boiler install and the work that has been completed at the property. I was very happy with how professional and tidy they were and can’t thank them enough for everything they have done.
Really pleased with today. The guys worked so hard and were extremely professional. Thank you so much. We will certainly recommend you whenever possible. We’ve already told number 7 how good they were !!!
