Ground Source Heat Pumps
Ground Source Heat Pumps allow homeowners to heat their homes via utilising the unlimited heat energy stored in the ground. They operate on the principle that the earth beneath the surface remains at a constant temperature throughout the year, and that the ground acts as a heat source in winter and a heat sink in summer.
Only a few feet from the surface there is an average temperature of between 6-12°C all year round as a result of the suns annual heat. A Ground source Heat Pump uses this energy store by collecting it and transferring it via the compressor to heat your home or premises, for year round use.
DHP-H & DHP-L Opti Pro ground source heat pump
The DHP Opti Pro ground source heat pump utilises the energy from the ground, bedrock or water to create a heating and hot water system. Incorporating an intelligent control system, the output is constantly adjusted to the prevailing requirement of the heating system, meaning that the heat pump will operate under ideal conditions for maximum efficiencies.
State of the art heat pump
The DHP-H Opti Pro has an inbuilt 180 litre hot water tank and the DHP-L can be coupled to a 300litre cylinder, featuring Danfoss’ patented TWS (Tap Water Strafication), HGW (Hot Gas Water) and Opti technologies combine to create a heating solution like no other. By controlling the circulation pump during hot water production, the Opti technology replenishes the stock of hot water quickly. The higher temperatures are achieved through the HGW process, resulting in additional volumes of domestic hot water.
DHP Opti Pro is a ground source heat pump that produces more and hotter water than other forms of hot water tank heating, while consuming less energy. All Danfoss heat pumps include the Danfoss on line Kit for controlling the heat pump via the internet or smart phone.
Opti technology incorporates an intelligent control system that via speed controlled circulation pumps ensures that the performance is always adjusted to the prevailing requirements and conditions of the heating system. This ensures the heat pump always operates in the most efficient manner. It delivers maximum efficiency with minimum energy consumption guaranteeing you the highest possible SPF, second by second, hour by hour.
HGW (Hot Gas Water heater) technology
A small proportion of the heated water that is destined for the house’s heating system is passed over the extra heat exchanger (de-superheater). It is then heated up further to between 50–90°C before going into the water tank. The result is extra and even hotter tap water during the months of the year that the house is heated.
TWS technology (Tap Water Stratification)
Danfoss has developed a unique and patented method of water heating; TWS. This function results in more efficient heat transfer and more effective layering of water. The method supplies plenty of hot water quickly without producing ‘unnecessarily’ hot water. This allows a TWS equipped heat pump to retain its phenomenal efficiency. A TWS water heater uses a technique where the hot water from the heat pump is led through a coil in the water to be heated. The water in the heater is also split so that some of the water reaches the correct temperature more quickly. TWS provides a more efficient heat transfer and more hot water.
