Poultry Farm, Shropshire – Water Source Heat Pump

Quick Facts

Sector: Commercial
Project: 200kW heat pump
Location: Shropshire
Energy Output: 320,000kWh per year
Carbon Saving: 19 tonnes CO2 per year

“TGE Group understood our heat requirements as a poultry farm and designed and installed a heat pump system that will have a big impact on our energy costs in the future. We are delighted with the results and look forward to extending it into new sheds in the future.”
Steve Dixon, SA & DE Dixon Ltd

The Project

Poultry farms have high heat demands in a continuous rearing cycle throughout the year.  TGE Group’s extensive experience in this farming sector enabled Steve Dixon, a Shropshire poultry farmer, to reduce escalating bills by replacing the existing LPG heating system with a tailor-made heat pump design that took advantage of the farm’s natural resources.

The Solution

During the technical site survey, TGE Group identified a lake near to the rearing sheds (pictured here) as being able to provide the necessary heat for the pump. The surface temperature of the lake averaged 4⁰C whilst the bed remained at 8⁰C during the year. As the lake is used for commercial angling, it was essential that the lake temperature was monitored so not to affect the habitat of the resident carp.

TGE Group designed the water source heat pump, using a Hidros 200kW, to supply heat through a new fan coil radiator heating system for two rearing sheds. The installation included 600m of horizontal collectors laid in the lake and connected to manifold chambers. These were connected through an underground heat main to the plant room and the metered heating system.

“Water source heat pumps are a good way to provide space and water heating and can be adapted to a range of moving bodies of water including canals, lakes, rivers and streams.  The cost is less than standard ground source heat pumps as it does not require significant ground works.  Heat pump systems are more efficient than conventional heating systems generating five times the output for each unit of input. In this case, the farmer will save 33% on equivalent LPG heating bills a year, added to the income from the RHI, this will result in a significant return on investment.” Matthew Evans, Heat Director, TGE Group.

Energy Saving

The heat pump will reduce the site’s carbon emissions by over 19 tonnes per annum. The installation is eligible for the commercial RHI generating a 22% return on investment with a five year payback and a projected £1 million in income and savings over the 20 year RHI contract.
