The water water heat pump is much more efficient in terms of when the average outside temperature drops below 3 ° C. The heat pump has a very stable heating capacity at low outdoor temperatures, so the outdoor unit is not required. This feature provides two main advantages: first, simple installation due to the fact that there is no need for an external device, and therefore the connected pipelines, and secondly, there is no phase of fittings which further increases the level. The heat pump water water fall into the most efficient energy system heating. Heat groundwater, in fact, a very reliable and constant energy source, given that its temperature is between 7˚-14˚C.
