Pitt Farm Cottages

Holiday accommodation business keeps running costs under control with a biomass boiler


A charming group of barn conversions, Pitt Farm Cottages is located in the picturesque coastal village of Branscombe in Devon. It is the idyllic location to enjoy a self catering holiday in an area known for its outstanding natural beauty. Our clients were keen to utilise both RHI payments as well as fuel cost savings as a result of conversion to help improve their profitability. One of the key future requirements was the easy billing of their tenants.

The Challenge

Pitt Farm Cottages was keen to convert their system of heating oil to a reliable technology that will offer long term fuel cost savings whilst being able to reap the rewards of RHI payments. The owners at Pitt Farm Cottages were keen to replace their heating system to one that runs on wood chips.

The client wanted to use the fuel cost savings and RHI payments to help improve their profitability. A key future requirement was the easy billing of tenants.

Complete Biomass District Heating Package

Wye Valley Energy installed the boiler, fuel delivery system and buffer tank in the plantroom as well as the heat main to connect all of the buildings included in the district scheme.

Consumer interface Units (CIUs) were fitted into each property, giving all of the controls such as timers, thermostats and RHI complilant heat meters in a single package. As there is no combustion occurring at the point of use, the CIUs do not need an annual safety check. The heat meter included in each forms the basis of easy client billing.

Renewable Heat Incentive

A 100kW project of this size would expect to receive Renewable Heat Incentive (RHI) Payments of £11,038 or more a year and to gain a fuel cost saving versus oil of 50%-80%.

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