The Scottish Executive's Central Heating Programme and the Warm Deal Annual Report 2003-04: BENEFITS FROM HOME ENERGY EFFICIENCY SCHEMES IN SCOTLAND 2003-04: A REPORT BY THE SCOTTISH EXECUTIVE
Case study 2
Mr and Mrs Warrington rent their 1960s end-terraced house from Midlothian Council. It was improved under the Partial Central Heating Programme.
Before improvements
Prior to improvement, the property was heated with an off-peak electric warm-air system with a dual immersion system providing the hot water. Although Midlothian Council had already topped up the loft insulation to 200mm, insulated the cavity walls and installed double glazing, the NHER was still only 4.6 and it is estimated that the Warringtons were having to spend over £650 a year on fuel.
Improvements carried out under the Central Heating Programme
Midlothian Council installed a gas-fired condensing combi boiler in the house, controlled by a room thermostat, a programmer and thermostatic radiator valves.
The effect of improvements
The improvements have increased the NHER to 7.5 and it is estimated that the annual fuel bill will be around £440 a year. Carbon dioxide emissions are expected to almost half from 7.9 tonnes per year to 4.1 tonnes per year. Mrs Warrington said that they had seen a big difference in their fuel bills since the new system had been installed.
