> Air to air is much cheaper and is more efficient because it doesn't need to raise the temperature of the working fluid so much and doesn't require a big fluid to water heat exchanger
It might still be worth it to go with water based system if you're going to have underfloor heating. It requires lower water temperatures, so efficiency hit is not that big compared to air-to-air systems (if there is a hit at all).
As a bonus, there are some savings from using the heat pump to heat the hot water for showering and you get the supreme cozyness of warm floors.
On the other hand, now you need some other way of cooling in the summer as underfloor system will not work for that.
- kwhitefoot 3y agoWe rarely need cooling. Average annual temperature is 14°C, maximum last year was 31.5°C in July but the average that month was 17.8°C :-)
- fragmede 3y agoHopefully that lasts! Where I live it didn't use to get hot, so no one has air conditioning, but for the past three years we've been hit with a week of 32°C/90°f + temperature. Those that can afford it have added air conditioning, but as global climate change kicks in, I'm expecting more extreme weather to become the norm.
- ChatGTP 3y agoI don't want to be rude, but the fact people install are conditioners for 1 week of 32°C is absolutely ridiculous. The majority of the world deal with these temps for months on end without A/C.
- fragmede 3y agoI mean, not everyone went out and bought one, a lot of people just put up with it. But a window AC is roughly $200, which fits within the disposable income budget of the middle class.
