ASHP v GSHP. ST or PV diverter.
I need to decide in the next month which system to install. Can anyone give me some pros and cons of either system. I have space for ground loops.
The other question is solar thermal or solar PV diverter like immersun as I have 3.7Kw PV already.
New self build timber frame, MVHR, UFH, well insulated, about 290sqm, 3 bathrooms, 4 person occupancy.
This is a example. Ivt is a Swedish based company who I believe is owned by bosch. IVT also make the worcester range of gshp, this ashp unit is maded in Japan and i think is a rebadged version of the Mitsubishi ecodan (which is regarded as best in industry). Also does cooling? patience and eBay... I will be honest there is somebody selling a broken one as well on eBay, but that wouldn't put me personally off this unit.
