I have a typical 2 zone [ upstairs & downstairs ] zoned radiator based central heating system.
Both are on seperate timers / room stats...... the room stats for both the upstairs and downstairs are in the hallway and landing respectivly.
I'm putting thermostatic valves on the bedroom radiators in an attempt to regulate the bedrooms temperatures. I want to dispense with the upstairs room stat as it's clearly not efficiant in allowing the rooms to warm due to the interferance from the downstairs heating - equally when the rooms are warm it will rely on the upstairs hallway radiators to 'tell' the stat that all is warm enough.....
So.... can I dispense with that upstairs room stat and control the upstairs flow from a thermostat on the return water temperature from the upstairs heating water. If so, would a cylinder stat do the job or maybe cobble something from a combi spare or......
I'm guessing that 1 rad upstairs mustn't be thermostaticly controlled so the IS a minimum return? Or maybe I should put a flow to return loop in the boiler room to stop the pump straining.
Any good books on designing central heating systems maybe?
Thoughts please?
