HEAT PUMPS
Most efficient with whole house underfloor heating
You have heat pump technology in your home already, in the form of your fridge, and perhaps even your tumble dryer. Heat pumps are certainly not new, and as with underfloor heating, have been used in domestic properties in Europe for many years. The technology is therefore tried and tested, and has proved its worth, even in countries much colder than ours.
AIR SOURCE HEAT PUMPS

5 kW ASHP serving our underfloor heating in this 3-storey property near Lauder. This property also has our MVHR system.
At this new build in Duns, the ASHP connected directly through the wall to the DHW cylinder located in the garage.

Air source heat pumps are the easiest to install because they don't need pipes buried in the ground. They take energy from the air, multiply it through a heat exchanger using a process of reverse refrigeration, and deliver it to your heating system and DHW cylinder.
Even at very low temperatures, your heat pump will be able to produce enough energy to heat your home and your hot water when the outside temperature is as low as minus 20 Deg C outside. (Source: Mitsubishi and Vaillant)
GROUND SOURCE HEAT PUMPS
This GSHP is fed from 2 boreholes, and provides hot water for our underfloor heating and Nibe solar DHW cylinder in this large granary conversion near St Boswells. The project also has our solar thermal panels.
Situated in an outbuilding with solar thermal panels on the roof, this ground source heat pump is fed by horizontal ground collector pipes. Installed in 2006, it heats the DHW cylinder if the sun hasn't already done so, and also heats our UFH in the adjoining new build house.
Ground collector manifold for a larger capacity ground source heat pump at a listed building near Coldstream. The GSHP heats our underfloor heating, and the DHW cylinder, which is also fed by a large array of solar thermal panels.

Ground source heat pumps take energy from the ground via horizontal collector pipes laid in trenches, or via boreholes. Boreholes are more expensive, but they can be installed almost anywhere, subject to ground conditions. The efficiency of GSHP is only marginally better than air source because the ground temperature at 1 metre depth remains relatively stable at around 10 deg C all year.
GRANT AND LOAN - Existing homes only
If installing underfloor heating and a heat pump to ensure low fuel costs for the lifetime of your property is not enough incentive, subject to your eligibility, the Energy Saving Trust/Home Energy Scotland offer grants for the installation of renewable energy devices in existing properties. Check your eligibility by calling Home Energy Scotland on 0808 808 2282.
If you wish to claim a grant and/or loan for installing renewable technologies in your existing home, your installer must be MCS accredited for the the technology you wish to install. It's important to check that your installer is on the MCS register because if they are not, you will not be able to claim the grant or loan. MCS accredited installers are annually audited for their admin procedures, quality of installation, and compliance with MCS standards. You can check the database here. Our MCS accreditation number is NAP 14681, in the name of Borders Underfloor Heating Ltd.
