If the grid wasn’t reliable, a hypothetical I know, it would probably be cheaper to switch over to a ground source heat pump rather than increase your panels by 3x. That would lower your winter electricity demand, albeit at the cost of significant capital expenditure.
- PaulDavisThe1st 5y agoDoes a ground source HP use that much less electricity than an air source HP?
- ashtonkem 5y agoYes, by far. It’s much easier to extract heat from ~55F ground water than from ~20F exterior air. Ditto for dumping excess heat into ~55F ground water than 90F exterior air. On average the water coming out of a geothermal loop will be more advantageous to work with than exterior air, which is why it’s a thing.
