The Problem

The project brief at this Cranwell property was to heat and provide hot water for a 4-bedroom 1970s 209m2, bungalow, updating the property from an old oil boiler with the latest alternative energy technology.

The Solution

The family here were growing more and more concerned about increasing oil prices. They were also interested in taking advantage of the Renewable Heat Incentive (RHI) payments and the Feed-in tariffs available with Solar PV; with the PV system to provide the electricity required to run the heat pump.

The existing boiler was removed along with the oil tank and replaced with a 12kw Panasonic TCAP Air Source Heat Pump system. The Panasonic system consists of 4 parts; the outdoor unit, the hot water cylinder, a 50-litre buffer tank and a heat exchanger. The heat pump is connected to the heat exchanger which is connected to an open vented heating system. The reason for a heat exchanger being used in this instance was that the existing heating system was open-vented and not suitable for a pressurised system.

The Cost & Environmental Savings

Prior to installing this system, the heating oil bills for the house were £2,200 per annum. The Panasonic TCAP reduced this to £1,300 per annum. The Solar PV installation also provided an income of £840 per year, index-linked and tax-free.

The RHI payments over 7 years will be £9,100 and the extrapolated PV FIT payments over 20 years are £30,678 – savings that are not to be sneezed at.
