Thanks for adding me to the group. We have bought an old rural school (Mouswald) from Dumfries & Galloway Council to convert into our home (3 bedroom and add second floor to one side - not a mez). Some pics attached and are at the stage of drawing up the Building warrant. Currently at the crossroads of deciding on what's the sensible choices/solution for ventilation/insulation for the walls/roof/underfloor. Council maintenance practices have been just as you would expect (patch repairs to lime mortar with cement and silicone squeezed in to cracks in stone / tarmac partially blocking vents) We have planning permission / a bat plan / archeology watch required when we dig founds for a detached garage. Hope to do as much as we can ourselves as budget tight. Apologies in advance for any daft / repeat questions #WhatHaveWeDone #We'llGetThere
So I'm looking at some home hydro technology - I've figured out the basic control system - I'll route it around and switch it in and out using the Fibaro HC2 that is controlling the rest of the building. So we can have a water level sensor on the run into the leet, and in the culvert to trigger for any fault / low level conditions - we'll use a signal from the Thermal store - either direct from the thermostat or via a Z wave thermostat to sense load requirement. So that just leaves the question what to do with the excess load, I could route it to a dump load, but that would need a potential 3kw load that doesn't trip out - so in the first instance it'll get fired into the Towel rail circuits (but thats not enough load), but the question that springs to mind is could I simply drop the excitation current from the genny and let it run into the towel rails? I'd expect to need some load in case of back EMF in the genny making power? Or am I over thinking it and I just need to switch of the excitation current? Naturally we could do it all wet side (stop the water flow), but that seems more prone to jamming and failure than this approach?
