Return is calculated using combined bill savings and subsidy earnings. Bill savings are calculated using estimated energy usage and either the electricity price at the time of installation (1 July, 2011) or, for our heating products, the existing fuel type available to the property.
The Education Centre in Holbeach iis a Serviced Office run by Lincolnshire County Council and also houses a Food Science Development Facility for the University of Lincoln.
The varied needs and uses for this busy centre meant energy usage was high and so the Centre’s Management approached EnergyMyWay to help them indentify and deliver a more cost effective solution.
After a thorough evaluation, it was determined that installing two Hot Water Heat Pumps complimented by an array of Solar PV panels would best meet the facility’s requirements.
Hot Water Heat Pumps combine an Air Source Heat Pump and a hot water cylinder in an innovative way that can provide over 1,000 litres of mains pressure hot water a day with energy savings of up to 75%.
EnergyMyWay installed a pair of Ecocent units from Earth Save Products. The pumps were set up to draw in air warmed by the waste heat from the food development kitchen and use it to create fresh hot water, removing the need for a gas hot water heater.
This arrangement allowed the gas fuelled water heaters to be decommissioned and so fuel bills for hot water have been greatly reduced as a result.
The cost-effectiveness of the installation was further enhanced by a 3.76 kWp Solar PV system, which generates an income of £1,400 a year from the Feed-in Tariff.
