Lynhales Nursing Home

Key Facts;

Project Included

  • 2 x Lindner & Sommerauer 99kW boilers in cascade and a 150kW biomass boiler system.
  • Flue system, thermal store and distribution pipework including internal connections to heat exchangers also included.

Fuel Consumption

  • 104 tonnes of wood pellets, per annum. (Based on system of similar capacity, in a similar application).

Fuel Cost Saving

  • Wood pellets 20-40% vs oil. This would be approximately £8,000 per annum (Source; Biomass Energy Centre)

CO2 Saving

  • Up to 98% or 154 tonnes vs heating oil. (Source; Biomass Energy Centre)

RHI Payments

  • A project of this size would gain approximately £38,140 every year for 20 years, index linked to inflation.

Total Project Price

  • £200,000

Payback Period

  • 5-6 years (Combining RHI income & fuel cost saving).

*Financial information not specific to this project – figures are based on an average of several typical projects of this size. Current information on RHI payments for guidance only, not to be considered a guarantee.

Project Summary

Recent Case Studies

Background

Lynhales Hall Nursing Home is set in seven acres of wood and parkland with ornamental lakes. The Manor House, now refurbished, was built in circa 1588 and extended in the Georgian Period.

The Main House comprises two floors of single and shared rooms, the majority of which have en-suite facilities providing accommodation for 53 residents.

The Requirement

The driver for the customer was the reduction of a large annual oil bill to heat the nursing homes and offices. The system would need to replace 7 ageing and inefficient oil boilers.

Complete Biomass Boiler District Heating Package

Rainbow Heat and Power carried out a turnkey project including all ground works, trenching, primary and secondary connections, erecting buildings and civils. We also organised and oversaw the construction of a new building to house the biomass boilers and fuel store.

Renewable Heat Incentive

As well as fuel cost savings of 20-40%, the installation will soon be accredited  into the Renewable Heat Incentive. Once approved, the client will start to receive quarterly RHI payments. The RHI payments and the fuel cost saving will ensure that the project is sustainable and financially viable.

The RHI Payments and fuel cost savings combined will give a 5-6 year payback.
