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 September, 2012) or, for our heating products, the existing fuel type available to the property.
The Loudor Guest House in North Hykeham near Lincoln, is a small family-run guest house that was purchased a few years ago. The building dates back to the 1930s and was originally a private residence.
The owners were refurbishing the guest house and adding extra rooms. Therefore, with additional guests generating consistently high energy and hot water demand, they were looking for ways to reduce energy bills and to demonstrate a commitment to sustainability.
EnergyMyWay installed both solar panels and a hot water heat pump at the Loudor Guest House. A 4kWp Solar PV system was installed on the flat asphalt roof. The Panels were perfectly aligned to face south and fitted onto specialist Console units so that no penetrations were made through the roof covering, allowing the roof to be easily recovered in the future.
The hot water heat pump installation recycles hot air from the kitchen to create fresh hot water. The overall hot water storage capacity was also increased by 50% as part of the work thereby minimising the risk of residents running out of hot water. Gas consumption for hot water was also considerably reduced and is only really used as a back up to the heat pump.
