Fastest UFH actuators?
Currently I have have a standard (22mmm thread?) 230 VAC thermal actuator that turns on or off the return from the UFH manifold, as a part of the heating /cooling comtrol system. This actuator is a NC one, that opens when 230 VAC is applied. We have a minor problem in that when there is a call for heating or cooling there is a delay before this valve opens. This doesn't matter in heating mode, as the ASHP can unload into the buffer tank, but in cooling mode the only load is the UFH, and becau
Just fitted this Salus auto balancing valve, but fitted in a slightly unusual way, as all our loops are run as a single circuit. I fitted it in place of the normally closed thermal actuator valve that was on the return end of the manifold, not as one of the loop control valves as Salus intend it to be used. It was a direct replacement for the existing normally closed thermal head, so was easy to fit. It comes with two clip on temperature sensors (not marked - either can be flow or return) and
