Heating Controls for New Build with UFH

BMD

Hi,

I am looking for some advice regarding heating controls for a new two storey build with UFH. The house is 290 sq ft. All rooms have south and north facing windows with the kitchen and living room having a lot of south facing glass.

I was thinking about having four zones downstairs based on usage;

1. Living room, kitchen and utility room
2. Reception room
3. Office
4. Hall and downstairs toilet

Upstairs I was thinking of 4 zones;

1. Master bedroom (ensuite)
2. Two small bedrooms and bathroom
3. Guest bedroom (ensuite)
4. Hall

My heating system will be a combination of solar, OFB and solid fuel stove (with back boiler).

I will also be installing heat recovery ventilation

I would be grateful for any advice on this with respect to thermostats, controls, water etc. as this is an area I know little about.

If it was me and i was going to all the effort i would class each room as a seperate zone , with its own thermostat and you can get a manifold with motorized valves to achieve this .
To me this helps you in a variety of ways
1. offers more control , each room can be individually fine tuned this will help save energy.
2. if your installing stove or fires etc then then it will help you by the thermostat shutting off each room as the heat from these sources spreads .
3. Get good digital thermostats the dial type ones arent accurate enough there can be out by 4 or 5 degrees or more at times.

Are you using a buffer tank to link all the heat sources ?

I am using a 300l triple coil copper cylinder to link all three systems.

Will I be over complicating things by having zones for every room? This would equate to 13 or 14 zones. I imagine there would also be quite a cost implication?

most underfloor systems use a stat for each room, controlling the manifold, ie, each room is its own zone, your underfloor supplier should fill you in.

Over time the heat recovery ventilation will even out the temperatures throughout the house.

If you have different thermostat setpoints different temperatures wont be achieved.

You would be better putting your money into weather compensation.
