Hy guys, im not in the business (so i appologise in advance for my lack of technical terms!) and i want to install an ASHP system for my bungalow (new build, 80m2 and highly insulated) for hot water bath/shower/underfloor heating....

I have sourced (boxes with fan that sit outside the building) from ebay a

Samsung AQ18UGAX 5.8kw and a
Toshiba RAS-18GAH-ES2 5.45kw

now i think both of these are for air conditioning systems but i was wondering whether i could use one as an ASHP to power a hot water system assuming i can buy all the other components individually and if its possible who could i talk to about it?

Im in London

Many, many thanks in advance for any help
