So I've been doing some research and stumbled across this great forum. My situation as follows:
Live in a large 2 storey plus roof conversion Victorian house currently on an old system with cold and hot water tanks and open vented central heating system. Currently on an old potterton gas boiler. Plan to rip it all out and start again as rads are at least 25 years old and boiler grossly inefficient.
Have ruled out Megaflo as I don't think we will have any issues with pressure and can't see us having issues with multiple baths showers running at same time. Probably looking for the biggest combi possible, such as a Worcester Bosch WB42CBI and will do away with hot water tank and come straight off the boiler for hot water.
I originally was planning on zoning the system; splitting into three zones, but thinking the Evo Home might be a good option to save on pipe work, motorised valves etc and possibly work out cheaper with better control.
My main questions:
1) I need Rads for 4x bedrooms, 2x living rooms, hallway and 2x bathrooms. Also need to future proof for underfloor heating in kitchen when I do my extension. My main question is, does it make sense to use the individual Evo home rad valves on all radiators? Or could I have hallway and 2x bathrooms come on all the time when the boiler runs. In effect they would behave like traditional Rads on normal thermostats which could come on with a timer or when any of the other Rads call for heat?
2) The Evo home valves. How efficient are they at detecting temperature drop in large rooms? Is it possible to have a separate temperature sensor in the room which then signals the temperature to the Rad valve? My concern being that they hit temperature and the room is not warm (I guess the solution would be to set a higher temperature in this instance, which means lots of trial and error and tweaking?)
3) Underfloor heating. What Evo Home valve / system do you use for this?
4) Interference / signal issues. I'm in quite a big house and read some people having issues with signals and connectivity; is this a known issue to anyone? I'm planning on having the boiler in the roof on a gable end and would like the control system on the ground floor will this be an issue or can I hard wire from boiler to control panel?
5) System balancing issues. Presumably the engineer can balance the system ok with Evo a Home valves or does it become tricky.
6) Finally, are there any other alternative systems out there or does anyone know of any planned new systems / upgrades to Evo Home which others on here use and would recommend.
Sorry for the long post, but any thoughts / pointers to further information would be greatly appreciated
