Best air to water heat pump services
There are differences between air-to-water heat pumps. The power of the outdoor unit is usually indicated in the model designation and specifications. All air-to-water heat pumps are inverter models, i.e. their power is adjusted as needed. In private houses, 8 kW outdoor units are most often put. However, there are astonishingly large differences. An example of outdoor units from two well-known manufacturers. Let's imagine making water at -7 outside temperature of 35 degrees on the floor. (This is some kind of standard that all manufacturers have to state in a document, not necessarily in that brochure) Manufacturer 1. Rated power of the device 8kw. Power at -7 outdoor temperatures —> 8.8kw Outdoor unit weight 114kg Manufacturer 2. Rated power of the device 8kw. Power at -7 outdoor temperatures —> 6,6kw Outdoor unit weight 60kg The differences only increase the colder the outside air gets and the hotter the water needs to be made, for example, in the radiator network. In practice, this means that the earlier the outdoor unit runs out of power, the earlier heating with direct electrical resistance begins, and more electricity is consumed. A simplified and easiest way to compare outdoor units is to see how much they weigh. In this case, excess weight is overwhelming.
