Energy Fence blends solar and geothermal heating and hot water

Energy Fence blends solar and geothermal heating and hot water

A new fence developed in the UK blends solar and geothermal heating to feed a ground source heat pump to deliver heat and hot water.

Hero Renewables developed the Energy Fence that takes clean and free, renewable energy from direct sunlight and also captures solar heat located in the ground and transforms it into heating and hot water for residential use.

The fence provides heat straight from the environment to feed a ground source heat pump that delivers renewable heat and hot water into a home. In the UK it can also generate payments from the government's Renewable Heat Incentive (RHI) into the homeowner’s bank account.

The fence is a series of tubes filled with a heat-transfer fluid that circulates through the system similar to a solar thermal rooftop collector or a geothermal ground loop. When using a heat pump to supply heat only 1/3rd of the fence is in the ground and 2/3rds above the ground. The section in the ground is used as a buffer during the night and on cold days. In combination with the ground collector, the energy fence may also be used as a separate roof absorber, e.g. fixed flat on a garage roof above the height of maximum snow cover. The Energy Fence is available in sizes of 44, 54, 64 and 74 stacked pipes and an Energy Fence of 54 stacked pipes will be provide approximately 1 linear meter per kilowatt output of the heat pump.

With both its air and ground components, the Hero Renewables Energy Fence provides a ground source application boosted by both the ambient air temperature and direct sunlight. Shrubs and plants can easily be landscaped around the fence to preserve the classy elegance of your garden or anywhere ground space is at a premium.

The energy fence is meant to give homeowners financial incentive to use renewable energy as the UK government's domestic RHI pays for using renewable energy from energy efficient ground source heat pumps, biomass boilers and solar hot water systems.

The RHI It is a financial incentive scheme designed to encourage uptake of renewable heating among domestic consumers. The domestic RHI is targeted at, but not limited to, homes off the gas grid. Those without mains gas have the most potential to save on fuel bills and decrease carbon emissions.

The scheme will cover single domestic dwellings and will be open to homeowners, private landlords, social landlords and self-builders. It will not be open to new build properties other than self-build.

The tariffs have been set at a level that reflects the expected cost of renewable heat generation over 20 years. Payments will be made on a quarterly basis.
