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

[Highway Man]

Why is a heat pump expelling heat from the house?

It removes the hot air when in cooling mode from the evaperator to the condenser outside and expels it into the air

effiency, and now hot water, they heat and cool.

Not much

I've always classed these as electric heating, and electricity costs more than gas. Offices have had them for decades; American homes have had them forever. USA electric is much cheaper than ours so they can afford it. People in offices don't care about the cost as they're not paying!

So, the hot water only works in cooling mode?

That’s what I’ve said at least twice. You need a tank.

Never said you didnt?

No it works in reverse in heating

Never said you didnt?

And don’t forget the upfront cost!

OK, yes, I was thinking of the heat recovery part you mentioned.

Air source heat pumps are mainly useless. Gas training is £10k, air source heat is free and takes a week….


They’d have to pay me a lot to get involved

Yes thats just an air con mmonkey mate, I agree with you. Fridge men don't come cheap and look upon air con engineers as monkeys,

The unit would always make heat for the hot water. He’s saying the bit of free heat saves a fortune

The running is cheaper and more efficient too, upfront costs are a bit steep but pay back is long term.

As gas men look at both of them.

I still waiting for cost and COP ?

The running is about the same lol. Unless you want to elaborate on the maths for us please ?

Do you know what a refrigeration engineer does mate?

If so it's an air to water heat pump. HWM was talking about air to air. Wasn't he?

Not in the least it doesnt. Gas is way more expensive and innefecient
