Depending on how hot/cold/windy/wet the wether is outside changes how fast different rooms cool down or heat up. It's an old house thing.

Will certainly look into this varying head issue. I'm not sure how my dad's system gets around this - he has a 5 zone system (3 central heating zones and 2 hot water cylinders). Used to have a bypass with the old boiler but perhaps the new one has variable pump or internal bypass? 3. You...

The idea is you have one room (hallway perhaps) with the roomstat and no TRV. Rad is turned down so that room heats up last and when it does get upto temp it shuts down the boiler. I'm working on an expencive but foolproof system of individual circuits controlled by roomstats.

An initial plan was to have a separate zone for each room with its own valve. Insulation is difficult as the house is solid wall, single glazed sash - conservation area. Will be insulating under floors and in attic to the maximum possible thickness. Are there any technical issues with...

CMzone was close - but those valves on the rads are ugly!

All these sounds like work-arounds though - heating up some rooms slowly so they heat up last - I've one real chance as I'm re-furb'ing the house to do it right - do it once. Costs are spread over years. Hometronic - is that total home automation like control4 systems? Don't quite need that...

The problem I find with TRVs is their proximity to the radiator means in a large room they're slowing the flow well before the rest of the room is getting upto temp. Plus they don't give any feedback to the boiler... meaning until a bypass rad heats a hallway or similar upto temp for a...

Yep, can't be hastled with constant adjusting of TRVs. Wanting to set it and go. My initial rough idea was a digital room stat combined with zone valve for each room. ZV's mounted somewhere easy to get to like in the hallway since we know how much they like to stick. Base the whole system on...

Ok so I'm after advice on the mother of all central heating systems. Rather than fiddling with TRVs and adjusting them weekly (daily even) as ambient temps raise and fall, I want to automate the system as much as possible. Currently got an old Combi providing the 'umph', but the rest of...
