Air to Air Vs Air to Water Heatpumps. Now closing the gap.

Yeah I knew that, if you had proper experience with it all you wouldn’t be so enthusiastic about it all lol.

I think nosey is jealous
in general, air to water heatpumps are pretty useless, we had 3 Daikin air conditioners installed at our house, absolutely amazing for the hot summers we are getting, I would fully reccomend air con heat pumps, we used them over the winter for heating, they were fine, I wouldnt rip out my boiler though we still use our combi for hot water.

Like I said they have a place, they just aren’t the future.

Using gas for your hot water proves that mate lol

Nosey is a troll but no one takes the liar on anymore. He’s not a challenge

We had an air to water system which was no use at all, we ripped it out and swallowed the cost and had the air to air heatpumps installed, only cost us £4,800. The air to water was already installed when we bought the house, it was pretty useless and had to have it on 24/7 to keep the radiators barely warm.

That’s the issue with air source heat pumps.

I’m still not sold on air to air to warm a large house though. But I can see that are moving in the right direction.

It would be interesting to know how long your cylinder takes to warm from cold, just using your air to air

We havent got that feature on ours, but we have the option of it if we want to swap out the outdoor unit with the hot water feature on it. We use our gas combi for our hot water. We are looking at installing solar for the hot water then the feature of the outdoor unit swap would be beneficial.
 
Can someone tell me what unit I need to give me 150L of water at 60° in a few hours, when it's -10° outside?
They can but they work to assumptions that properties are insulated to current standards and take a temperatire that is mean not a lpw, so additional heating os often required. Add to that problems with installation.

Ironically a mate is doing two days at Daikin this week. He’s going to ask about the recovery time on air to air heating a cylinder.

What can? I said HW, so insulation is pretty much irrelevant. It boils down to needing a few kW from air that's at -10°.
The power needs to go through whatever necessary to get the water temperature up to say 60°, not just a lot of slightly warm water. I know that can be assisted by processes such as "zorbing" zeolite. Theoretically - do they use that?
What box o' tricks can do the job for a house?

In all honesty & joking aside I feel the expense of a heat pump in the region of 20k is excessive. The 3 units of air con heat pumps that we have for 5k all supplied & installed was our best purchase ever. We are delighted with the cooling during hot weather and equally impressed with the heating that we get from them in the winter. They work well for us but may not suit everyones heating needs, certainly as far as cooling goes they are a god send.

Does it depend on the temperature difference. Say outside is 263K and refrigerant is 233K.

Are they independent units, as in one per area, or have you have them ducted into each room ?
