We've recently moved into a new house which has a Concord WRS boiler, gravity fed hot water with pumped central heating. There are TRV's on all of the rads but no motorised valve. Everything is controlled by a Danfoss 102 mechanical programmer.
I have a couple of issues with it, the main being the innacuracy of the programmer, trying to get it to come on exactly when I want is proving tricky, and occasionaly if I override the controller during the day it seems to forget to heat the water the following morning
The other is that the house is a detached house with concrete floors so once it's cooled down it can take an hour or so before the rooms start to warm up.
The whole lot is going to be replaced in the next year or two when we extend so I don't want to make huge changes to the exising setup but i think I have two options to try to improve it.
The first is to replace the controller with an electronic version, giving better control over when the heating comes on.
The second is to add a room stat, I had a programmable one in the old house which would allow the heating to drop down while we were at work, then heat the house in the evenings and weekends. I think I could add a wireless stat to the existing setup and leave the danfoss on constant. I'm confused about what would happen in the summer when the stat isn't calling for heat, how would the boiler know to heat the water?
Am i missing anything else here?
Thanks
