I'm near the Canadian border in northern New England and am getting ready at work to have another vertical ground source (geothermal) heat pump put in, and those are very effective year round. Well loop is around 515' (~155m), which is on the longer side but not a big deal by well drilling standards (which is why lots of well drilling companies have been expanding into heat pumps in the last 5 years and availability has sky rocketed). The price is definitely much higher than air source for now, maybe always will carry some premium, but the major government incentives here help significantly and of course the reliability is high. There are a few minor other bonuses as well I guess, like aesthetically speaking once done there can be nothing to near nothing visible outside. There are a few other strategies (horizontal ground, water source, semi-open) that some are looking at too but around here simple vertical closed looks likely to end up as the majority due to economies of scale, it can be done anywhere vs needing more/special land, and like I said leverages an existing industry. It's neat to see coming along, so perhaps longer term that'll offer an option in Northern Europe too.
