HEAT PUMPS
A heat pump installed correctly can reduce energy by as much as 30%-60% compared to oil. All the below heat pumps will cover 100% of your hot water and heating needs.
AIR SOURCE
Air Source Heat Pumps absorb energy from the outside air in the same way that a fridge extracts heat from the inside. It can absorb heat from the air when the temperature is as low as -20°C. These systems require no civil works and are therefore an ideal solution for most existing houses. One disadvantage of Air Source Heat Pumps is that they are susceptible to salt air corrosion, special coatings are used to prevent this, and so installations that are closer to shorelines continue, but with caution to the homeowner.

GROUND SOURCE
Ground Source / Geothermal Heat Pumps extract heat from the ground via a closed vertical / horizontal heat collector. Ground Source Heat Pumps allow home owners to heat their homes utilising the unlimited heat stored in the ground. They operate on the principle that the earth beneath the surface remains at a constant temperature throughout the year, acting as a heat source in winter and a heat sink in summer. Passive cooling (using minimal electricity pumping cost only) in modern houses accounts for a swing back to WaterFurnace Heat Pumps.
WATER SOURCE
Water Source Heat Pumps extract heat from water via an open loop / lake / pond heat collector. They use well water or water from a stream / river as its heat source, which is pumped through the heat exchanger and is discharged back after the heat is extracted. Due to the high temperature of underground water the efficiency of a water source heat pump typically exceeds 500%. This can also be used in conjunction with a domestic well water supply, which then provides two solutions in one.
