Discussion ... ASHP(Air/Air) with Solar pv ....

OK I'm getting a little further ('though obviously will miss the heatwave). Does anybody have any experience/views of the LG Libero range? I can't see them mentioned here but they seem to fit the bill i.e. reasonably priced and extremely controllable.

Thanks

Not the most efficient, but that's what I have, the 3.5kW model, very cheap, very quiet.

The recent heatwave has reminded us of your comment when we were considering getting an air conditioner/heat pump.

Your missing one major point.....how much is a good nights sleep worth when we get a heatwave(uncommon I know)?
There's been a good few days this year I've had the aircon on all day(for free) and had to get under the duvet at night to keep warm while all the neighbours have their windows wide open trying to keep cool...for me...that's priceless

For the last few days we have had the aircon on all day at 22C cooling the lounge, but also with the internal doors open, the rest of the bungalow. It has worked a treat; and all using solar generated power :beer:

As this thread is about the small scale use of solar and heat pumps, I thought, just for a laugh, I'd point to the more extreme end to show just what is possible:-

Recently had a questionaire from E.on about them potentially providing Air Heat Pumps. Proposed cost was between £5k - £9k fully installed, to save approximately £100/year on energy costs!

So even based on the lowest cost, it would take 50 years to pay for itself, not allowing for inflation or loss of interest.

Hi

Perhaps the E.ON representative (malc) could feed back information to management on how ridiculous their option is to a sane person! ...

Little bit of ASHP today, almost all PV supplied. Cool.

Don't you mean "Warm" :cool:

Had ours on a few times recently when its been a bit cool; all PV supplied and very quick to take the chill of the room.

Hi

Same here, but I've decided to open up all of the internal doors and assist the solar gain to charge-up the house as a thermal mass store today ... same as you, all on PV ... :cool:

Same again here, all internal doors open, so the warm air is flowing to all the other rooms. We also have solid internal walls (and cavity filled external walls), so they also act as a thermal mass store retaining and then releasing the heat in the evening when the sun goes down.
