Plumbing Johannesburg Supply & Install Heat Pumps
Heat pumps are one of the most efficient domestic hot-water heating systems available, and with the right application can cut heating costs by utilising solar heat from the surrounding environment.
Heating geyser water is typically the largest energy cost in homes today. Approximately 75% of a heat pump’s heating energy comes from the environment while only about 25% of external energy (electricity) is needed to achieve a heat output of 100%.
How A Heat Pump Works
A heat pump will replace the current geyser’s electrical element, resulting in saving you money. In effect, a heat pump will transfer heat from a source (air) that is sucked over the condenser, by means of an electric fan, to heat another source (water).
Latent heat energy of the air is transferred to the gas within the condenser coil, which pre-heats the gas and reduces the work that the compressor has to eventually do. The compressor increases the pressure and the refrigerant gas is heated as a result of the increased partial pressure.
The coefficient of performance (COP) is a measure of the performance of a heat pump. A typical value for COP is four. The heating capacity is four times the amount of electrical energy that is required from ESKOM.
The saving can therefore be up to 70% on water-heating costs, dependent on consumer usage patterns, ambient temperatures and the humidity of the area.
A dedicated controller allows the user to set operational times and desired water temperature. Some factory pre-set values, and onboard error codes, ensure safety to the end user.
