Unvented Cylinder + Vaillant Bolier HA5

The greatest benefit of an unvented cylinder aside from the excellent water pressure, is that unvented cylinders are highly energy efficient. They also require less space than open vented cylinders, as there is no need for a cold water storage cistern. With an unvented cylinder you will also have the ability install a TMV3 approved blending valve at desired hot water outlets which reduces the risk of scalding. As unvented cylinders do not need to be connected to a tank in the loft, they can be installed with greater flexibility if space is an issue.

Here we went for the Gledhill Stainless Lite Plus with a Vaillant Boiler. A very happy household was the result.
