Description

The intasol combi diverter valve enables solar heated unvented hot water cylinders to be linked with a combi boiler. In the event the hot water temperature in the cylinder dips below a usable temperature, the valve diverts this water to the combi boiler treating it as a pre-heat. The valve then blends hot water produced by the combi boiler or the cylinder with cold water from the mains to deliver water at a safe, usable temperature for the end user.

Review

This product sets you back approx £300, however it’s purpose is to optimise energy savings and increased reliability in a combi and unvented solar setup. It does this by making sure if the cylinder is hot enough, the water is sent straight to the taps at a settable temperature. The water in the cylinder needs to be at 48 degrees or higher.

If however the temperature is below 48 degrees then it will get sent to the combi boiler at approx 28 degrees to be brought upto the combi boiler desired hot water temperature, saving energy by not requiring to be heated from cold. Either way the output temperature goes through a TMV Temperature Mixing Valve before being sent to the taps.
