This is feasible. If you are a project that needs a system to remotely control the heat pump, please tell us your specific requirements or the effect you want to achieve. 2.How deep is the pipes of ground source heat pump buried? Laying buried pipes generally require a depth of 2 meters, and vertical buried pipes require 100 meters deep or more. As for the tiled area, you need to consult your installation engineer for advice, because the geology of each area is different, and the parameters are different. 3: Air to water heat pump is heating faster? Air to water heat pump heating rate according to the water temperature and outdoor temperature Summer inlet water temperature and outdoor temperature are high,so heating faster. In winner inlet water and outdoor temperature are lower,so the heating is slow.
