Hi,
I have a two storey house with an oil boiler zoned heating system and two motorised valves. There is a horstmann H37XL control unit that has three buttons, one for downstairs and one for upstairs and one for hot water.
My first simple query is whether you should get hot water only when you hit the water button? would you not have hot water anyhow when the heating is on?
Or is this button for hot water without heating the rads?
Anyhow, both motorised valves work and the zoned heating works perfectly. But no hot water, whether I hit that water button or not.
I believe the system is a gravity feed system and we have a small header tank beside the main water tank.
Is there a valve somewhere that could be closed either on the pipes somewhere in the hot press.
Our immersion works fine.
Thanks
Barry
