The Mill House was undergoing renovation when isoenergy was employed to install new energy systems. The house is on the banks of a fast stream which historically ran the mill in the building.

The owners of the Mill House approached isoenergy to help reduce their heating and electricity bills. The property relied on LPG Gas for heating and hot water and the fast flowing stream provided the perfect energy resource.

We installed a 30 kW heat pump system which collected heat from two banks of EnergyBlade heat exchangers submerged in the stream.

isoenergy oversaw the installation of an Archimedes’ screw micro-hydro system to generate electricity for the house and out buildings. Surplus generated electricity is sold to the grid. isoenergy installed river level sensors to protect the heat pumps and Archimedes screw from low flow during dry periods. A fish pass was also installed.
