A SOLARFOCUS 60kW log boiler has been installed at a rural property in Aberdeenshire, helping to save on the rising costs of oil. After investigating the various options available, the customer opted for a log boiler, but keeping their existing oil boiler as a back-up. The customer loved the idea of using locally sourced wood in the boiler to provide the most cost effective means of heating, whilst the existing oil boiler could be used if they were away from home.

Grange House is a stately 150 year old traditionally built granite manse in North East Scotland. The previous heating system used a 35kW Rayburn oil boiler with a large wood burning stove to provide supplementary heating. If fully heated using oil alone the property would consume 7-8,000 litres of oil per year at an annual cost of about £4,800. However the owner was merely
turning the oil boiler on enough to have one ‘golden hour’ of heat in the morning and again in the evening and then using the wood burning stove to its full capacity as they could not afford to heat the whole house on oil alone.

AD Heating recommended the installation of a SOLARFOCUS 60kW log boiler with a 4,000 litre thermal store housed in an outbuilding. The existing oil boiler was kept and integrated with a 3-way valve so that it could be used as a backup system as required, such as during holiday periods.
