Energy Saving Improvements Details
The property is a detached 4 bedroom house built around 1978 but with a later extension.
The orginal gas fired boiler was replaced in 2010 with a high efficiency boiler. This also required the flue to be changed to a vertical system, discharging above the roof. The heating controls were also improved when the boiler was installed.
The owner checked the electricity consumption of the existing appliances with an appliance meter and discovered that the fridge and the freezer were both very inefficient costing around £90 each per year. They were replaced with A'rated appliances saving £160 a year in electricity costs.
The property has undergone a number of other energy saving improvements including cavity wall insulation, increased loft insulation and double glazing and mainly low energy lights.
The Energy Performance Certificate puts the house in band C with SAP72 producing 3.4tCO2 annually.
