Here's the problem.......
I have a oil fired burner heating the rads and hot water cylinder in m house (new self build house). The house heating is divided into 4 zone
- Hot water, downstairs rads, upstairs rads and kitchen rads by motorised valves. These valves are actuated by four switches located i the kitchen. I should also mention that the only room thermostat that have is in the kitchen which will close the motorised valve when i gets to temperature.
So if I wanted HW and the kitchen warm for the morning I have to mak sure before I go to bed that the two motorised valves are left open.
The problem that I have is what would happen if the heating was turne on and the only motorised valve open was the one in the kitchen? As fa as I can make out the thermostat will close the motorised valve and th the heating pump will keep pumping but the water will have nowhere t go.......
What would be the best solution to this?? I've thought long and har and the only ideas that I can come up with is ..... (bear in mind tha I'm new to this)
A: Wire the power for the boiler through the motorised valves, i they're all closed then the heating will switch of. or B: Build in a by pass on the plumbing, but I'm not sure how this wil work either. Do I need to add pressure switching valves or what???????
Any help much appreciate
