Yep thanks for that, they're popular here as well (as well as simple variants like a big coil of black plastic irrigation pipe lying on the ground).
In my case I'm trying to put all my investment into a heap of solar panels, as that's a more general purpose infrastructure.
- Havoc 8y agoConsidered the black pipe stuff...but I'm not convinced the plastic doesn't leach nasty crap into the water. I assume you have gas heating & cooking then? If they're elec its usually cheaper to buy new ones than up-spec the solar PVs.
- abraae 8y agoHeating's optional around here but we use LPG (propane) for cooking. Cooking's the last big hurdle, wife refuses to consider a wood burner.
- dlgeek 8y agoYou can get systems that use heat exchanges - the water that goes through the black pipes circulates closed and heats up a separate potable water supply. https://www.energy.gov/energysaver/heat-exchangers-solar-water-heating-systems https://www.energy.gov/energysaver/heat-exchangers-solar-wat...
- Havoc 8y agoThat's clever. We were considering it for heating a pool. Iei lay the pipes on a hot roof in the sun
