GSHP vs ASHP
Newbie here sorting through first build in ICF and awaiting Architects preliminary sketches. House is 1650 sq ft per level, 2 levels plus basement and a separate 400 sq ft garage with apartment above. As well as heating for this there is the driveway to heat approx 1500 sq ft and a swimming pool 900 sq ft. We’re on 2.5 acres in Napanee Ontario near Kingston with space for GSHP.
Really early days yet, house is barely a collection of ideas but what system would work for us, CC ASHP or GSHP. If it was 4 or 5 years ago I would have leaned on GSHP but there seems to be a lot of improvements in efficiencies with ASHP. It’s hard though to find a consultant who would objectively give us costings on the options. They seem to push one system or another.
Are there limits to how much an ASHP can cope with since we’re adding in driveway heating and pool? In which case we’re back looking at GSHP.
