Background
Resident comfort is a priority for the owners, who were experiencing large heating bills from the three old and inefficient oil boilers they were using to heat this Grade II listed building.
The Requirement
We won a competitive tender for the supply and installation of a 150kW Linder & Sommerauer biomass boiler which will run on EN Plus grade wood pellets.
Two 2,000 litre buffer stores, all associated fitting accessories and a wood pellet fuel suction system were also included. As part of the project, Rainbow also managed Hay House’s RHI application.
Complete Biomass Boiler District Heating Package
We installed the boiler, fuel delivery system and buffer tank in the plantroom as well as the heat main to connect the main house.
Financial Benefit
A 150kW project of this size would expect to receive Renewable Heat Incentive (RHI) Payments of approximately £17,000 per annum and to gain a fuel cost saving versus oil of 20-40% or approximately £3,500 per annum.
The fuel cost savings and RHI payments combined will deliver a payback on the capital cost of the equipment in 5 years.
