Ground Source (geothermal) Heat Pumps
The latest and most efficient heat pump technology, geothermal or ground source heat pumps offer exceptional energy efficiency, they work by utilising stable sub ground temperatures to generate heat through compression.
GSHPs are more efficient than the more common Air to water heat pumps, which are heavilly influenced by fluctuating input temperature
Heat is extracted from the ground by a closed loop collector which is laid in trench or field area
Field area or 
Trench
The amount of collector required is dependent on the system load and is also influenced by the ground type, the best ground being wet and sandy - the worst being rocky ground which will require the pipe to be laid in a layer of introduced sand. Typically
collectors will be somewhere from 500m to 1000m in total length, usually run 32mm alkathene which is charged with a water/glycol mix.
We strongly recommend you use the services of a specialist engineer, or alternatively use of a collector design program to calculate the amount of collector required but as a rough guide you should allow at least 70m per KW of output
load required in your system
Several design calculators are available on the internet
for example www.gaiageo.com has design calculators for both domestic and commercial applications including a free demo version
The collector will require an additional pump with the capacity to circulate the glycol mix through the GSHP we can supply a pump based on the length and diameter of the collector. (not shown in our store site)
Our range of European Spec, GSHPs are manufactured using the latest technology by Hiseer in China to comply with exacting European specifications. Please do be wary there are also poor quality heat pumps coming from chineese
manufacturers.
The latest technology and exceptional value for money from a genuine world class manufacturer
Our range of GSHPs include
Standard units available as heating only or with a factory fitted domestic hot water diverter ( allows the unit to provide both heating and domestic hot water heating through a coiled cylinder)
In addition,
we have a 10Kw unit capable of 70 degree output temperatures this is a market first and allows the GSHP to be used as the heat source for a traditional radiator heating system.
GSHPs are by indent order only - a 50%deposit applies upon placement of order - Please allow 6- 7 Weeks for delivery
GSHPs from Savona technology at its best
