Hi,
I will soon be installing a multi-fuel stove with back boiler (Woodwarm Fireview 9 with 8.82kw to water) in my living room, with the intention of heating my hot water indirectly and running some radiators. I have done some research on load valve systems and very much like the concept.
I have a schematic drawn by the stove manufacturer and wondered if anyone had any thoughts.
the schematic is at: uuuuuu.woodwarm.co.uk/Rugulus_TSV_02.pdf
The schematic looks good and has allowances for power failure.
The 2 things that concerned me were:
1. It looks to me that circulation pump failure could impede the back up gravity flow/thermosyphon circulation, Would that be the case? To allow for such a case could a LK Acaso Termobac/Thermobac valve be used to allow gravity flow instead of the "power failure bypass zone valve", number 3 on the schematic? As I believe this would, correctly fitted in a circuit, open in case of power failure or pump failure. To find the valve google LK 822 termobac
(I can't post hyperlinks!)
2. Should there be another normally open zone valve after the boiler flow is teed off into the cylinder coil? I was thinking that when the pump is running and the cylinder is up to temperature, the radiator/ heat leak circuit will open, but should the cylinder coil close to avoid boiling the contents?
I hope this all makes sense.
