Thanks - that's the source of my confusion - valve shaft turns properly with very little finger pressure- hence why I don't see the actuator having a problem turning it (especially as the actuator turns properly when removed from the valve.) But I just wanted to sanity check my theory of it...

Thanks for that - hadn't thought to check the voltage - doh! Will do so and act accordingly. If it isn't receiving the 240V then I assume that's down to the control board on the dreaded Boilermate...

Sorry - it's a Danfoss valve with an HSA3 actuator. The tree I'm barking up is thinking that it's the actuator, it's just I thought I would check first as the valve is so easy to turn by hand that it seems strange the actuator is not strong enough to do that. But I guess it can't be a lot else.

Hi, can anyone help? I hve recently had to drain the system completely, twice, to have a radiator replaced, but I'm hoping this is incidental to the problem. Gledhill thermal store - but that's irrelevant really. Hot water is fine (valve in the non-actuated position.) Central heating only gives...

Thanks for the reply. I have no complaints regarding the hot water, so the standard 15-50 is doing its job there - which I guess isn't surprising if the control circuitry of the Boilermate itself modulates the pump. I assume I am right in thinking that just because a pump is not a modulating...

Hello all, I hope you can help. I have a Gledhill Boilermate III thermal store (I know most of you hate them, but it is what it is.) This system is fitted with two pumps. Once circulates water from the store to boiler (via the rads if CH is on) and the other circulates hot store water into a...
