hi folks,
i am based in Ireland and at the moment i am building my new home a 250 sq meter story and half domer. I have been looking at air to water heat pumps for the underfloor heating side of things on both floors and also dhw for showers and bath there is 3 ladies in the house so lots of hot water wasted. prices of a 13 kw air to water heat pump are around €12,000 to € 15,000 c/w a 300 litre storage tank. After picking myself up from the ground after receiving the prices i said what is really in these units that make them so dear, i have decieded that i am going to build one of these unit. So lads and lassies can some one point me where to start sizing this.
i hope to use a copeland scroll ( what size), gas R410A, plate exchanger ( but what size) a 300 litre hot water sorage tank ( i will have solar as well to heat water in summer and 5 kw back boiler on a stove to help in winter. Any and all advise welcome and i know i have overlooked somethings so please be kind with your comments.
thanking you all in advance Engineer Lowe
