What is a Heat Only Boiler?
Do you want an affordable way to update your old-style boiler? Then why not consider installing a heat only boiler (also known as conventional or open vent boilers)?
This type of boiler requires other components outside of itself, including hot water cylinders (located in the airing cupboard), feed and expansion tanks (in the loft), central heating pumps, and motorised valves.
The best part is that you don’t have to make any changes to your existing heating system when installing one of these boilers – making it cheaper than converting to a combi. So if you’d like us to give you a free quote for a new heat only boiler, just get in touch with us!
We work all over Gravesend as well as Dartford.

Heat Only Boiler Questions & Answers
Are heat only boilers any good?
If you’re thinking about replacing your boiler, a heat only one could be the answer. They work especially well in properties that require a lot of hot water: they can easily cope with demand that would be too much for a combi boiler. What’s more, they usually operate on an open-vented system, with a feed and expansion tank in the loft – this keeps your pipes and radiators at a safe pressure level, which is especially useful if you have an older central heating system that can be more vulnerable to leaks and damage.
What is meant by heat only boiler?
The contemporary term for what was formerly known as a conventional boiler is a heat only boiler. These types of boilers are used to generate heat, however, additional components such as a hot water cylinder and pump must be installed in order to obtain both hot water and heating.
How efficient is a heat only boiler?
When it comes to boiler efficiency, there’s no comparison between a modern heat only boiler and an older model. Modern boilers are rated at 91%, whereas conventional boilers are far less efficient, with ratings as low as 55%. Why keep paying more for your heating when you could upgrade to a new boiler and save money?
