I need a plan for piping and operating the cottage heating/DHW system!
Progress so far... gas supply and meter installed. Largest thermal store I can fit in the space, installed. Upstairs and downstairs underfloor heating pipework laid and coupled to separate manifolds.
Buffer tank? It has been suggested that running the boiler to satisfy a thermostat calling for heat for say a bathroom circuit will lead to boiler cycling and inefficient operation. How does one include this in the control system and how large does it need to be.
The thermal store is probably undersized based on the usual shower/bathroom number calculations but space limited. With the expected slow response from underfloor heating, it seems best to prioritise the DHW.
Chalet bungalow with limited headroom. Pressurised system? System boiler? Serious lack of knowledge area:-)
Apart from picking the brains in here, is there a useful on line source?
