Unvented Systems

If your home or business has been fitted with an unvented heating system, it’s advisable that you get it serviced every year to ensure it keeps running effectively and working as it should. Unvented heating systems operate without a cold water tank, and instead, cold water from the mains is fed directly to the sealed hot water cylinder.

Thanks to the fact that your unvented heating system is operated at mains pressure, you benefit from a heating system with better flow rates. The result? Showers and baths that operate better, and the ability to use more than one hot tap at once without a reduction in performance.
 
Unvented systems offer a fast response from the moment you turn your hot tap on to the time it takes for the water to become hot. This also helps to ensure running costs are economical and kept as low as possible. Another benefit to having an unvented system is the fact that noise levels are reduced as – unlike a conventional open-vented system – there is no water storage cistern to be filled with cold water. Furthermore, because unvented systems don’t need gravity to pump water around your property, the unvented cylinder isn’t restricted to a specific location. That means this style of heating system is particularly useful if you don’t have a loft space.

So if you’re thinking of having an unvented heating system installed in your home or business, or you need to get your existing system serviced, our skilled UK Gas Heating engineers will be happy to assist. Installation of an unvented heating system is quicker than conventional systems so disruption is kept to a minimum.
