motorised valve

Hi all, Long time listener, first time poster but this forum has been invaluable to me in my recent heating system exploits. I live in a late Victorian house with what seems to be a heating system installed in such a way as to save a bit of cash wherever possible. As far as I can tell it's a...

This forum helped me a lot many times in the past and hopefully will help again. I did search and despite there are many posts related to the valve issue, I could not find one similar to mine. Motorised valve on CH zone 1 circuit does not seem to work correctly and doe snot open fully when it...

I have two Honeywell 2-way motorised valves (1990 vintage) in my airing cupboard, one for CH and the other for hot water. The CH valve got stuck in the open position. I investigated best i could, took the cover off and managed to shift it by pushing gently in one of the brass cogs with a...

We have a combi boiler running a single zone system over three floors. All rads have TRV's apart from the middle floor bathroom. I would like to upgrade and provide better control over our heating and try to reduce our running costs. I started to read up on the Honeywell Evohome smart system...

Hi, I've just bought a house and it has a hot water tank (Elson Opal) and a power shower. For some reason when showering, after a certain amount of time, the hot water just stops and the shower can't run. It's not that there's just cold water, there's almost no water coming out at all. The...

Help please We had a new Worcester Bosch Greenstar 30cdi system boiler fitted just over 2 years ago by a large power provider. Came with a free two year maintenance contract which ended two weeks ago. Last service was carried out under that contract in February. Over the last few weeks since...

Hello, I have a situation that may resonate, I think there could be two faults: Situation: excessive oil being used in heating/hotwater system, pump never turns off, radiators often hot even when programme is set to off/off. There is a drayton motorised valve on a Y valve Often one can hear...
