Evening all....
More questions again, thanks in advance chaps.
Basically part way through a job where they are having:
... just trying to suss it all out, have hardly ever done any heating systems before, in at deep end here and like the challenge. I've got no problem with reading wiring diagrams, but it is how each system links with each other that gets me? Plumber hasnt got much of clue either, great! Trying to get to grips with just basics first. This is what I understand so far:
Airsource:
Solar:
Underfloor Heating:
Most of the gear is located in same cupboard which makes it easier and the airsoure is directly outside. Just have to run cable upstairs for cylinder stat and solar if required.
Customer asked me today how he would switch between airsource and solar, any ideas what happens here?
Hope someone can make some sort of sense of that and maybe point me in the right direction. I have got someone that can help out if I really do get stuck but want try and do this off my own back,
Cheers again,
Sy
More questions again, thanks in advance chaps.
Basically part way through a job where they are having:
- Underfloorheating (wet system)
- Airsource heat pump
- Solar
... just trying to suss it all out, have hardly ever done any heating systems before, in at deep end here and like the challenge. I've got no problem with reading wiring diagrams, but it is how each system links with each other that gets me? Plumber hasnt got much of clue either, great! Trying to get to grips with just basics first. This is what I understand so far:
- Underfloor is split into 3 zones - stat for each back to manifold
- S plan system being used: 2 zone valves, pump, cyclinder stat, programmer, cylinder with 2 coils (one for solar, and for airsource)
- Airsource heat pump and solar takes the place of the boiler in a conventinal S plan system
Airsource:
- Power in understand ok.
- Pair out to pump, understand ok.
- Controller which just plugs in, just for setting temp diagnostics etc, understand ok.
- Water temp sensor, goes to thermal store or buffer tank if have one ?
- Pair shown on my drawing going out to boiler ? Why would you have boiler and also airsource pump?
- Pair out to each zone valve... no terminal but says to connect to directly to 2 white wires in PCB... but I will need 2 wires for each zone valve so surley I would need 4 wires to connect to?
Solar:
- Apparently plumber is installing it, would there be any electrics involved?
Underfloor Heating:
- Havent had a chance to look at this properly yet, have just got a stat in each zone wired back to maifold.
Most of the gear is located in same cupboard which makes it easier and the airsoure is directly outside. Just have to run cable upstairs for cylinder stat and solar if required.
