Daikin heat pump installation equates to an energy saving of 35%

A Nottinghamshire couple has seen their energy bills fall by £1,000 in the first year since installing a Daikin Altherma air-to-water heat pump. Mark and Julie Burton who live near Mansfield, Nottinghamshire, saw a staggering 35% energy saving compared with their previous boiler.

Following renovation and extension works to their 16th Century home, Mark installed a Daikin Altherma high temperature air-to-water heat pump to replace their existing oil fired central heating system, together with under floor heating throughout the ground floor of the extension and standard radiators on the upper floor.
The air-to-water heat pump has provided an effective solution for energy provision as the farmhouse is off the gas network and therefore had to rely on oil. Since installing the Daikin Altherma heat pump, the couple no longer has to await further supplies of oil whenever their tank runs low. It also provides a more sustainable heating solution responsible for fewer carbon emissions. These benefits, coupled with increasing oil prices, made a heat pump the obvious solution.
The system is capable of providing flow temperatures of up to 80ºC, which is more than adequate for the radiators, under floor heating, and domestic hot water provision, even when external temperatures fall to -20ºC.
Mark Burton reported that: “The Daikin Altherma High Temperature system ticked every box. I could retrofit the unit as a direct replacement for my costly, inefficient oil fired boiler, plus it meant I could rely on relatively stable energy prices throughout the year, with no more worries that the £700 worth of oil stored outside in a plastic tank might be stolen”.
Air-to-water heat pumps work by absorbing latent heat from the air and converting it, via a condenser, into the central heating and hot water systems. The 16kW high temperature system has a high Coefficient of Performance of 3.72 when external temperatures are 7ºC and the heat pump produces a leaving water temperature of 35ºC.
Mr and Mrs Burton’s total energy usage from October 2010 to October 2011 was 4,860 litres of oil which cost them £2,916. The oil boiler was replaced by a heat pump, which during it’s first year of operation used electricity costing £1,900. This means that since being installed, they have saved a total of £1,016 on the annual running costs, equating to a saving of 35% on the running bills.
Air-to-water heat pumps are an established and excellent alternative to traditional heating and hot water systems in both new build and refurbishment applications. Demand for such renewable heating technologies is expected to increase dramatically in 2013, once the long-awaited domestic Renewable Heat Incentive (RHI) commences in the summer and when the Green Deal ECO “Affordable Warmth” scheme is underway.
