For other readers, this unit is a water heater, not an HVAC heat pump.

It would be interesting to compare it to other heat pump water heaters to get an idea if the performance is that much better, of if the interesting feature is its operating temperature range.

It is for an HVAC that heats via water - i.e. a radiator system. It heats water, but not for your shower.

It might though; lots of boilers are combi systems that do your hydronics as well as on demand hot water. For example another air-to-water system that competes directly with the one in TFA:

That might make sense, but as it doesn't mention any cooling features, I assumed it was purely for (faucet) hot water. The fact that there's no tank is weird if it was for residential hot water, I think you're right that it's for heating. (or combo, with a separate hot water reserve for showers)

I think it is targeted to cold weather markets for home heating retrofits that have gas boilers driving radiators.

Why do their diagrams include faucets and tubs/showers?

Notice the 3rd party DHW tank. There are ones with heat exchangers.

My father uses heated water to run this through his radiators and floor heating. Heats the space in the winter and chills it in the summer. Warm water is just the carrier.

Does this mean it can generate chilled water at peak solar generation time and cool the room in the evening?
