BENEFITS OF OPEN LOOP
Financial
Lower running costs – lowest cost of heating www.nottenergy.com/energy_cost_comparison
Potential grants available – Domestic renewable heat incentive will cover most of the installation costs
Independent water supply – no mains water required, saving you money on water charges
General
Most green source of heating - Higher COP than similar closed loop systems and using a Good Energy tariff http://www.goodenergy.co.uk/ ensuring all electricity from renewable sources, ensure the greenest from of heating
Domestic hot water up to 65°C all year round – with no additional power consumption or reduction in CoP
Better efficiency than ordinary GSHP – no drop off in performance during the winter as the source bore hole water maintains a constant temperature. Output efficiency relates to source temperature at MCS standard conditions this is 10C for Open Loop and 0C for Closed Loop (water out being taken at 35C, so the open loop system only has a differential of 25 to achieve rather than 35 for Closed Loop).
Minimal visual impact – externally all that can be seen is a manhole cover providing access to the borehole unlike air source heat pumps which have large exterior units
Compatible with low temperature radiators and under floor heating
MCS HP0164 Heat Pump Technology guarantees a high quality standard
National Support Network – a National support network of Approved Installers
High system efficiency throughout the year – year round high heat extraction as underground water temperatures remain constant
Less space needed – only a small plot needed unlike slinky (closed loop) systems
