JohnMo Posted August 21, 2022 Share Posted August 21, 2022 Been told we need cooling in the lounge and possibly in the bedroom (about 10m away from lounge) for next year. So looking for advise So two options, as I see it. May be others? 1. Get a heat pump with cooling, run through the UFH, most expensive option. Not sure how good it is compared to aircon 2. A2A, least expensive option, but depending on how many units I need could be more expensive. Could run in heating mode also if required. Not sure how to size? Not keen on pulling house apart to fit something and wife not keen on external units (but may have to live with one) Have seen through wall aircon, but input vs output doesn't appear that good. Water cooled aircon, main water in and then to drain, seems a waste of water. Link to comment Share on other sites More sharing options...

Kelvin Posted August 21, 2022 Share Posted August 21, 2022 Out of interest. Given you’ve not long built the house. Other than put active cooling in is there anything you would have done differently? Link to comment Share on other sites More sharing options...
JohnMo Posted August 21, 2022 Author Share Posted August 21, 2022 Think I would have shrunk some of the south/west facing windows, trouble is we have great views, seemed a shame to miss out on them. Link to comment Share on other sites More sharing options...
TonyT Posted August 21, 2022 Share Posted August 21, 2022 Head over to the Camelot forum , few members have installed A2A over the past few weeks… Link to comment Share on other sites More sharing options...

JohnMo Posted August 21, 2022 Author Share Posted August 21, 2022 We have big overhangs over the windows which is great until mid afternoon and the the lower sun going down to west get in. The internal blinds work quite well, but not good enough. Will have a look at external blinds also, thanks Link to comment Share on other sites More sharing options...
Russdl Posted August 21, 2022 Share Posted August 21, 2022 Or you could always go for trees… Link to comment Share on other sites More sharing options...
JohnMo Posted August 21, 2022 Author Share Posted August 21, 2022 Good suggestion, but there's a 45 degree slope down (down 8m) about 4m in front of the house, then a road then a loch. So not much option for trees unfortunately. Link to comment Share on other sites More sharing options...
ReedRichards Posted August 21, 2022 Share Posted August 21, 2022 A2A heat pumps can also be used very economically for heating in spring and autumn when it's not too cold outside. A heat pump with cooling is not a permitted development and would require planning permission. I presume this also applies to A2A. Link to comment Share on other sites More sharing options...
m0deller Posted August 22, 2022 Share Posted August 22, 2022 Did you go for a solar reflective coating on the windows? Seems to make quite a difference Link to comment Share on other sites More sharing options...
Mr Punter Posted August 22, 2022 Share Posted August 22, 2022 Air to air is great when the external air temperature is high. For solar gain only, external shading is a good solution but will make the room dark. Link to comment Share on other sites More sharing options...

So looking for advise How many story building? I find cooling in UFH on our ground floor "works" fine but creates a pool of cool air 1 ft off the floor downstairs that does nothing to help the building as a whole feel cool. FCUs upstairs are much more effective. (Conversely, the UFH is excellent for heating in winter) Edited August 22, 2022 by joth Link to comment Share on other sites More sharing options...

joe90 Posted August 22, 2022 Share Posted August 22, 2022 Is it worth the cost for the few days/weeks it’s required?, I have no heating upstairs but for the odd week or so in winter extra heating is required the plan is just plug in heaters. Why not consider portable air con units you can pull out of storage when required? Link to comment Share on other sites More sharing options...
