A 1923 uninsulated and single glazed property operating with an old gas boiler resulting in very high energy bills.
A complete energy retrofit was undertaken to modernise the property and use energy as efficiently as possible utilising available government incentives such as the Feed in Tarriff (FiT) and Renewable Heat Incentive (RHI).
Mantis Energy provided a performance and economic evaluation to select the most cost effective options, obtaining competitive quotes, discussing with the clients and arranging / supervising all installations.
A key advantage of the installed systems is the level of monitoring, automation and integration. The heating and hot water are controlled by usage and activity in the house and all appliances are monitored for energy use.
