Lynhales Nursing Home (Hereford)

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 as resident comfort is important. The system would need to replace 7 oil boilers on site (some will be kept as back up for the nursing home).

Complete Biomass District Heating Package

Wye Valley Energy carried out a turnkey project, organised all ground works and organised and oversaw the construction of a new building to house the biomass boilers and wood pellet fuel store.

System Summary

Wye Valley installed and commissioned the biomass boiler, and carried out the connections to the current heating system.

The district heating scheme included;

• 2 x Lindner & Sommerauer 99kW boilers in cascade. 
• 1 x 150kW biomass boiler.
• Wood pellet fuel store.
• 3 x 4m pellet delivery augers.
• 1 x 4,000 litre and 1 x 5,000 litre buffer.
• High efficiency system pumps.
• 2 x heat exchangers.
• 4 x class 2 RHI eligible ultrasonic heat meters with certification.
• Biomass boiler linked to exisitng heating and hot water system.
• Fully automated fuel delivery system.
• High efficiency, low energy main system pump.
• Full assistance with RHI application including schematic drawings.
• Commissioning, programming and end user training.

Key Outcomes

• Project Included: 2 x Lindner & Sommerauer 99kW and 1 x 150kW wood pellet boilers.
• Flues, thermal stores and distribution pipework including internal connections to heat exchangers also included.
• Fuel Consumption: 104 tonnes of wood pellets, per annum.
• Fuel Cost Saving: Wood pellets 20-40% vs oil. This would be approximately £8,000 per annum (Source; Biomass Energy Centre).
• C0₂ Saving: Up to 98% or 230 tonnes vs heating oil (Source; Biomass Energy Centre).
• RHI Payments: A project of this size would gain an average of £40,356 every year for 20 years, index linked to inflation.
• Total Project Price: £190,000.
• Payback Period: 5-6 years (combining RHI income & fuel cost saving).

Renewable Heat Incentive

As well as fuel cost savings of up to 40%, the installation will soon be accredited into the Renewable Heat Incentive. Once approved, the client will start to receive quarterly RHI payments.

A project of this size would expect to receive Renewable Heat Incentive (RHI) Payments of £40,356 or more a year and to gain a fuel cost saving versus oil of 20%-40%.

The fuel cost savings and RHI payments combined will deliver a payback on the capital cost of the equipment in 5-6 years.

The RHI payments and the fuel cost saving ensure that the project is sustainable and financially viable.
