Heating thermostat and building regs ?

aligarjon

Hi guys, maybe slightly off topic.  I have been asked by a customer to relocate her heating thermostat in a new build.  I haven't seen it yet so don't know the full picture but she says it is located in her attic room and doesn't shut off when they want  because it doesn't get warm enough or the rest of the house stays on because it's colder up there, so i am presuming it's a 3 storey house.  It seems a bit odd to me on the face of it, especially as it's June.  i thought each floor should have its own zone and thermostat to comply with building regs, is that correct.  This is just a standard wet system with radiators.

    Friends have a large but well insulated home with gravity circulation and no controls of any kind.

    A wood stove with back boiler heats a single loop of large bore pipe that runs around the perimeter of the upper floor. No radiators, the pipe is the radiating surface.

    To increase heat add more logs and open wider the draught to the fire.

    Average heating demand in the winter is estimated at about 8 kw. No way to measure this but estimated from the log consumption. “Winter” is judged to be about 3,000 hours. Log consumption is about 7 tons per winter. Calorific value of dried logs estimated at about  4.5 kwh per kilo and stove efficiency at about 75%. No great accuracy may be claimed in view of the number of estimates and approximations involved.

    I’m old enough to have extended domestic central heating systems using large bore steel pipework back in the 1970’s.

    It doesn’t tend to be an issue with modern small bore central heating system, but back in those days the problem was often stopping the gravity flow to get some control over the system. That were several occasions when we ended up fitting heavy brass back flow check valves which could be lifted by the pump, but stopped the gravity flow.

    I had extended a heating system in the home of the local vets in steel pipework and got it all working on the controls  after fitting back flow check valve to stop the gravity flow on the heating circuit. A few months later a mate of mine got me to go into partnership to buy a small patch of farm land and some calves with the intention of calf rearing on a serious basis. The calves needed attention from a vet, so I spoke to the husband whilst we were both working on a local farm, he said the heating wasn’t working and a deal was struck, he would look at our calves if I looked at his central heating.

    So the vet called and looked at our calves and left some drugs, I went and looked at the central heating to find out his wife had turned it off.

    I discovered a long time that many central heating “issues” can be resolved with a chat over a cup of tea.
