WATER

It covers 66% of the Earth's surface. It is where energy absorbed from the sun's rays is most easily and efficiently stored. Regardless of air temperature, (which rises and falls rapidly) at two metres below the surface water temperature remains fairly constant.

 

HEAT PUMPS

Heat pumps have long been recognised to be the most efficient way of providing thermal energy. They can take heat from the air (air source) or the ground (ground source) and, by using cutting edge technology, boost that heat to the temperatures required to provide heating and hot water.

 

WATER TEMPERATURE

The temperature of the River Thames at the riverside development in Kingston-Upon-Thames hasn't fallen below 7 degrees Celsius at 2 metres below the surface in the past 25 years. It generally maintains at 8-10 degrees Celsius.

 

Should the air above the river surface fall below 0 degrees Celsius, freezing the surface in ice would act as a blanket keeping the water beneath warm. Even in the eventuality of the water temperature falling below normal operating temperatures, the heat pumps will still perform at peak efficiency at -5 degrees Celsius.

 

This unlimited source of low-grade heat is available to serve the heat pump system 24 hours a day, 7 days a week, 365 days a year.

 

Regardless of the scale of demand that your district thermal energy system is required to meet, the Open Water Heat Pump System can be designed to supply all the hot water, heating and cooling demands needed.

 

ENERGY EFFICIENCY & CARBON EMISSIONS

Unlike currently implemented standard heat sources - gas, oil or biomass fired boilers whose energy efficiency produce Coefficients of Performance (CoP's) of well below 1 - the Open Water Heat Pump System produces CoP's of 4 to 6 or more - 5 to 10 TIMES THE ENERGY EFFICIENCY.

 

Vitally, unlike combustion boilers, the Open Water Heat Pump System does not burn anything and, therefore, produces ZERO CARBON EMISSIONS on site. Alongside the green electricity supplied by Ecotricity's wind turbines to power the system, the whole installation becomes
