BACKGROUND

Originally this particular client approached JM Renewable Solutions to come and repair his unreliable oil boiler system. He was having reoccurring issues and stressed the financial burden of the current oil boiler’s running and maintenance costs. However, after our initial free site visit we produced a consultancy document for the client, and highlighted the diminishing effectiveness, high running costs and poor carbon emissions of his current system. Within this documented we also provided a comprehensive proposal detailing the alternative renewable heating systems on the market and their superior performance. The client quickly became aware of the overwhelming advantages of switching to a renewable heating system and was eager to install.

After his previous experience, the client wanted the most efficient, reliable and self-sufficient heating system possible. The property required a system that would readily satisfy the heating and hot water demands of a family of 5 whilst reducing costs. With the inconsistent levels of comfort combined with the increasing oil bills, the property was to benefit significantly from the new heating system.

JM’s RENEWABLE SOLUTION

JM Renewable Solutions (JMRS) then designed and installed a 16kw Ground Source Heat Pump. They had enough garden space for the horizontal collectors whereby we worked together with our preferred digging company to install the necessary pipe work (dug 1 metre down and 1 metre between each pipe). When the pipes were layed, the garden was returned to normal with the system hidden tidily underground.

The ground source heat pump now accounts for all the heating and hot water in the house. The system has been designed to the specific requirements of the client, operating at 40 degrees and heats the hot water to a max temperature of 60 degrees. JMRS opted for a 200L unvented cylinder as this would provide more than enough hot water for the entire house. The house had a radiator system throughout the house with at least 1 radiator installed in each room, with added TRV.
