Reading comments here i think many are missing something, all of our summers are getting longer and hotter, we didn’t need air conditioning before.
It’s not just heating anymore, now places need active cooling too.
Heat pump sales rise across Europe

We have a ground-source heat pump for our ADU. We did it because we were curious about just how efficient we could make the house, but I don't expect that it will ever break even financially vs a modern air-source system with resistive backup in our climate (northern New England, typically very few –20˚ nights, –10˚-0˚ more common with daytime highs in the single digits). It works great, but it's hard to see a way to…
You might still get the most out of it when the AMOC collapses.
I'm not aware that AMOC collapse is going to significantly alter New England's climate as it will Europe's.

> DACH, an acronym for Deutschland (Germany), Austria, Confoederatio Helvetica (Swiss Confederation), the three major German-speaking countries I was not familiar with this term before, had to look it up.
It doesn’t even make sense though, shouldn’t it be DÖCH?
It goes by license plate codes https://en.wikipedia.org/wiki/International_vehicle_registra...
It makes for a fun acronym DACH meaning roof in german. If they used Ö why not DÖS with an S for Schweiz then ?

I think you mean https://en.wikipedia.org/wiki/ISO_3166
Because this consortium seemingly has nothing to do with receiving license plate assignments. And the acronym seems to derive from your general vernacular, lending its name to many other things.

The 'outdoor unit that looks awful' is an interesting quirk especially with US equipment - most Japanese and European residential units actually look fine, I'm not sure why American ones have tended to look especially ugly. I notice this with electrical stuff too - things like switchboards etc. in residential and light commercial installations we have quite neat stuff that's usually quite streamlined and in light whi…
Buying the panel box which is unchanged from the last 70 years and costs $50 less than a nicer new style, but also our houses are big enough the panel is nearly always in a mechanical room so who cares what it looks like.
You can’t get the ‘nice’ panels in the US - they aren’t approved by local code.

It's usually so much more expensive than an air source heat pump that makes it completely not worth it.
Yeah, recently saw some numbers for air-to-air vs air-to-groundwater, and it break even after more than 25 years, with more than twice the initial cost
There’s no way the system is designed to last 25 years though?

The fact that you need to roll out a drilling rig plus crew at all is going to be a large part of that cost. For it to become interesting for the average homeowner the price is probably going to have to drop by something like 75% - but that basically kills any margins for clever new innovations...
In some potential future, there is an engineered a plant/fungus in a pot that you place onto the worksite. Months later, with regular sugar-water and hormones, it gives you a root-pipe for pennies a day. Of course at that point we might not need the cheap pipe in the first place.
Nanobots that manage a plant / fungus / bacteria/‘ / amoeba workforce.
They drill and line boreholes to both anchor the foundations of the building and provide a closed loop system for a reticulated-water ground-sourced heat pump system.
They also use the soil recovered from the boreholes to build the soil-polymer foundation.
In the future, pallets of nutrient-cement are placed on the site and the bio-borg-bot farm also builds the entire building, including all the plumbing and wiring and windows etc etc, with the added benefit that it all looks like some weird alien / xenomorph Gigeresk hive excretion.

End users could have simple resistive heating.
But no, in the name of invitation and net zero, end user are forced to bear the cost and maintenance burden of much more complicated equipment systems.
It’s all arse-backwards.
