At Rosemary Cottage in Wherwell, Hampshire, IBD has designed and installed a new heating and hot water system based on renewables, using a Daikin Altherma High Temperature Heat Pump System. Owners Mr & Mrs Little had lived in the idyllic cottage for two years before deciding to replace the inefficient electric panel heating system in the Grade 2 18th century listed cottage.
“After two tough winters we decided that we must do something about the heating and also the high heat loss we were experiencing,” say Robert Little. A visit to the Ecobuild exhibition in London allowed them to assess the various heating alternatives. These were limited by the rural location of the cottage in a quiet country cul de sac. Oil heating, for example, was not an option as the cottage’s thatched roof would have meant significant structural alterations to the cottage’s chimney. An oil or LPG based system would also have cost much more to run and would have presented problems in obtaining planning consent for a storage tank.
From a renewables viewpoint, a ground source heat pump was also not viable due to the proximity of the cottage to the River Test. Having investigated the advantages of an air source heat pump installation based on a Daikin Altherma High Temperature (HT) Heat Pump and Hot Water system, Mr & Mrs Little contacted IBD, a Daikin renewables partner. “The company’s prompt response and its wide experience in the design and installation of domestic and commercial heating and air conditioning systems using renewables were instrumental in our selection of IBD for the project,” says Robert Little.
The specified Daikin HT System is a highly flexible, energy efficient home heating system that simply extracts the heat from the outside air and raises it to a higher temperature. It then distributes it around Rosemary Cottage through the new radiators that have also been installed. With its high performance air to water heat pump, it overcomes the issue of heat loss within the cottage and Mr & Mrs Little find that it provides exactly the heating levels they require as well as running the towel radiators. Should they need it, there is also an attractive open fire in the property.
The claims that the Daikin Altherma HT system offer more than 3-5 times efficiency than a traditional electric or fossil fuel heating system have certainly been borne out since the installation was completed in 2011. The electricity bills for the property have also dropped by 21% per annum. “The low running costs are very pleasing,” says Robert Little.
IBD project managed the complete Rosemary Cottage design and installation to time and to budget. This included the convenient outside install of the Daikin system’s indoor unit and hot water cylinder which could not be accommodated within the property’s limited internal space. A purpose built outbuilding was erected.
“We would recommend IBD’s services and have been delighted with the whole installation,” says Robert.
