Hi.
Wondered if you guys with a lot of knowledge could help. recently moved into a 3 storey (plus large basement) victorian house. installing a new CH/DHW system, and working out the best way to do it. Most heating/plumbing companies seem to know even less than me about evohome so could anybody offer advice on this.
Specifications are
CH and DHW demand equates to roughly 59-60kw - Can be met with either a single Light Commercial boiler (eg. Worcester GB162) or 2 smaller Domestic system boilers.
Pipework; too much for all on one circuit, so it is going to be arranged as S-Plan-Plus (I've attached a schematic diagram of what I think it'll look like).
Number of rads; 34 in total which can be nicely grouped into 11 zones.
My main questions are;
1. If we use a single boiler and S-Plan-Plus configuration, is this the correct layout (ie. the relay switching the motorised valves for both CH circuits on if any of the rads call for heat).
2. How well will this work if we install 2 smaller system boilers with the same S-Plan-Plus layout? Anybody got experience of this and have any advice?
3. Is there a better way of approaching this? Would it be better to totally separate the 2 CH circuits and have an evohome system on each one? (And perhaps even have 2 smaller separate DHW cylinders?).
Thanks in advance, and any questions or things I've not made clear, please ask. I'm not an engineer, I work as an anaesthetist with a fair understanding of how stuff at home works! I can understand stuff that I read about, but I'm not as versed in the technical stuff as some, so sorry if anything I've said is stupid!
Thanks,
Will
