In the past, some models have used
excessive electricity....the reason .....poorly installed heat pumps
or unsuitable ground conditions. These reasons would have made the
heat pump very inefficient
thus switching on supplementary heating unknown to the user. This
being the equivalent to heating your house/premises with an immersion!
Ltd has specifically designed it's geothermal open loop heat pump
to address this problem by the fact that we use water as our medium.
This water has been in the ground thousands of years and matches
the ground temperature. No matter how little or much is extracted
this water will continue to maintain this constant temperature all
As water typically enters
our heat pump at 10 degrees above the brine solution (used in other
heat pump products) the heat pump is in excess to 100% more efficient
than a closed loop system.
Due to the ground water
temperature being constant all year round, Enviritech's heat pump
has a constantly high efficiency. This then negates the need for
the offending supplementary heating.
To further curb your electricity
bill Enviritech will assist you in configuring our system
to optimize the benefit of night rate electricity.(commissioning)
In typical existing homes
with radiators, a study based on the
SEI Fuel Comparison Jan 2008 indicates that the running costs
of our heat pump will be approx. half of the cost of oil. In a house
with under floor heating it would be less than 22% the cost of oil.
Since January 08 oil prices
have increased dramatically making our heat pump an even more attractive
here to see our running cost comparison.
