The land agent was looking at reducing the heating costs for the Hall, tenanted buildings and offices, as well as providing an uplift in the heating capacity due to the limited size of the existing gas main.
As the estate had the capability of producing its own woodchip a 350kW Herz Firematic wood chip boiler with a 5,000ltr buffer was specified to provide the heat, with a back-up gas boiler connected to the buffer and metered for ineligible incentivised heat production.
A plant room was constructed within an existing farm building, with a new wood chip store constructed to the side of it. A district heat main was installed to carry the heat between the buildings, with a variable speed, temperature controlled shunt pump providing the heating control to each of the buildings.
J L Phillips designed, specified and installed the project within criteria set out by the client, the boiler is now providing heat to all buildings with the back-up boiler automatically engaging during maintenance, down time and wood chip fills.
