Domestic Hot water
This energy expense represents about 25% of the bill of the average Canadian household. It is also important for accommodations, catering and cleaning. Fortunately, many free sources can be used to fill this need.
Use of appropriate reserves can begin to benefit from free energy from the gray water and solar cells.
The system that operates both sources can operate passively, that is to say without requiring external intervention or consume energy. The installation cost is paid off quickly.
Other savings can be realized by the choice of equipments. Indeed, some air-water heat pumps can heat space and hot water simultaneously from the warm air outside. In addition, these facilities also produce hot water with the energy extracted during air conditioning. The combined system has these capabilities. Other units are intended for outdoor installation and produce only domestic hot water. These are ideal for a campground open only during the warm season, or a hotel located in a region where the weather is mild all year. These units produce hot water instantly and do not require any reserve.
Whether it is a water-water or air-water heat pump, an energy recovery water cooler system can transfer up to 35% of the heat extracted from a domestic hot water reserve.
Instead of throwing back heat from the air conditioning to the outside like the conventional units, the energy recovery air conditioner can use this heat which is initially for the purpose of heating water. Only the excess is discharged to the outside. This application is ideal for institutional buildings such as schools, hospitals and office buildings that require both air conditioning and hot water taps for bathrooms.
