I'm about to embark on the great adventure of fitting a new boiler to my extension I'm building. I've removed a small rad from the kitchen and installed approx 10m2 of UFH.
A couple of questions:
My exisiting Ideal boiler is coping, just about, with the system I have at the moment and gives plenty of HW and the CH don't take long to warm up. Its approx 15KW. Shall I take the opportunity to go up to say, a 18KW just to be on the safe side ? I'm going to change to a Vailliant Ecotec plus as they seem to have a good rep on the tinterweb. The boiler is approx 14yrs old and I may as well change it when the kitchen is like a bomb-site.
The kitchen has now become part of the dining room and I want to keep one rad in place and somehow integrate this with the UFH? Is this possible with Y-plan? I'm thinking a two port valve tee'd off the pumped flow of the new boiler feeding the dining room rad and then down to the blender of the UFH. Is this OK? Will I have to fit another valve into the pumped return to stop the exisiting pump playing havoc with the UFH?
I'm hoping to have a room stat in the kitchen/dining room extension to control this and somehow integrate it with the exisiting Y-plan setup I have, which I've yet to get my head around. Basically ending up with two zones, one being the rest of the house and the other, the new extension.
I don't really want to go down the road of completely redesigning the system to S-plan which I believe might make things a little simpler???
On the subject of integration Vailliant seem to have a selection of "add-ons" for their boiler range which might help simplify the process.. Or am I completely mad and suffering over googling syndrome ?
I'm hoping to just whack in the new Valliant, do away with the exisiting CH&HW timer/programmer, plug in some superduper add on from Vailliant that will control my two zones, HW and take commands off two room stats?
Confused? I am now
Cheers
