Property type: 4-bed, stone-built bungalow in rural Northumberland
Product installed: Two 8.5kW Mitsubishi Ecodan Air Source Heat Pumps
Distribution system: Radiators
Installation date: Commissioned January 2011
Artist and sculptor Keith Maddison and his wife Christine live in a 4 bedroom, stone built bungalow, which nestles in the historical and picturesque village of Elsdon in the heart of the Northumberland countryside.
Although beautiful, the temperatures can be unforgiving in the depths of winter and deliveries of fuel supplies can prove difficult in poor weather conditions. A hot water and heating system that relies upon these deliveries is certainly not ideal, and with no gas in the property to provide alternative heating, an efficient and reliable system is essential.
“Until now we have been relying on an AGA cooker fuelled by coke to provide the heating and hot water to the bungalow, but with solid fuel costs rising and supplies diminishing we had been looking around for a replacement,” said Mr Maddison. We were not happy with alternative fuel sources such as anthracite and pellet fuel and wanted a sustainable solution.
Mr Maddison wanted a cost-efficient, renewable energy supply that he could rely upon in all weathers, so he called in the UK’s largest and longest established renewable technology company, Ice Energy Technologies.
Dave Webb, Installations Manager for Ice Energy Heat Pumps Ltd, visited the Maddison’s property to advise on which new system the couple should install. Having carried out a site survey at the property he recommended they replace their old system with Mitsubishi Electric’s Ecodan® Air Source Heat Pumps.
“Originally, we looked at the possibility of using ground source heat pumps, said Mr Webb. “However, there was not enough space for a horizontal collector system, so early on in the design process we determined that an air source heat pump would be the right technology for the Maddison's property.
“We performed a full heat load assessment on the building and the results confirmed that the property required two air source heat pumps linked together to provide sufficient heating and hot water for the couples’ needs,” he explained. “The new system is controlled by an Ice Energy control system and heating is provided via a new radiator system, whilst hot water is supplied from a single 210 litre cylinder.”
- Two 8.5kW Mitsubishi Ecodan units were installed due to the bungalow’s very high heat load characteristics
- 210 litre cylinder
- Installed over a one week period in very severe weather conditions
