Delighted to sponsor Stuart Copland, and add him to the AJ Pottinger team of plumbing and heating engineers 💙

Ness United’s towering centre back has a great wealth of County experience under his belt, including eight Milne Cup appearances as well as various Island Games exploits.

The emergence of his club as a force in the local senior game coincidences with his early County appearances and his positional, ball playing and winning attributes will be crucial.

One of our customers retrofitted ground source heat pumps. Fitted with full open energy monitoring kit - without manufacturer’s fudging the figures - for heating and hot water. Combine system SCOP of 4.85 from installation. Made some adjustment to the hot water and should start to see the efficiency go higher. From installation Heating averages at 5.69 and hot water at 3.47. This makes it the 3rd best performing GSHP system in the uk at heatpumpmonitor.org. You can follow the system with the link in the comments. Stiebel Eltron UK Ltd

Something a little different, replacing an old over sized 12.5kw ground source heat pump.

Calculated heat loss at 5.89kw @ -3c, supply and install an inverter driven Stiebel Eltron with an output of 7.6kw. Fully inverter drive. With modulation down to an output of 1kw. 300l cylinder and 100l buffer to help with summer short cycling. Renew the undersized pipework to the UFH manifold. Remove the high temperature manifold to further increase efficiency’s and replace with a low temperature. Balance flow rates to each room as per the system design and heat loss calculations.

System running very well after around 2 months. Looking forward to seeing a full years average on the efficiency’s. They are shaping up to be excellent!
