Understanding Open Vent Boilers

What are Open Vent Boilers?

Continuing our series of helpful information on boiler technology we focus this time on open vent boilers. What are open vent boilers?

An open vent boiler is also known as a regular or heat only boiler. The open vent heating system usually comprises of the boiler, a hot water storage cylinder and where required a feed and expansion tank in the loft.

Open vent boilers can consistently supply hot water to a number of taps at the same time. They work well if you are replacing an old open vent heating system, and are ideal if water pressure is low in your area.

Open vent boilers are also compatible with solar water heating and heat pump systems for a lower carbon footprint and lower energy costs.
