Cotswold Water Park is located in an area of natural beauty, boasting 140 lakes and offering an extensive range of leisure activities.

The Gateway Visitors Centre is designed to be the main visitor focus and information point for the whole park.

This spectacular building is constructed from sustainable green oak and is a beacon for sustainable, rural development in the South West. The centre embodies sustainability and energy efficiency boasting an effective combination of solar and water sourced energy.

Kensa Heat Pumps was selected for their technical expertise and product and application superiority. The team followed a comprehensive assessment of the building and site potential, heat loss calculations and energy source in line with total project objectives and the high standards expected by the Cotswold Water Park.

Kensa’s 300kW Commercial Plantroom heat pump system sources heat from the lake to deliver 100% space heating to all buildings in the Gateway Centre.

In addition, the centre also benefits from a system which comfortably switches to cooling mode during the summer months, dissipating heat back into the lake. The solar PV roofs are one of the largest in the South West providing power to the centre and will also meet the electrical power requirements of Kensa’s Commercial Plantroom heating and cooling system.

The heat pumps are connected to the buildings heating and cooling distribution system, which consists of underfloor heating in winter and chilled water fan coils for cooling in summer. With a total heating and cooling capacity in excess of 300 kW, this is one of Europe’s largest pond heating/cooling heat pump systems. All the components were specified, designed, manufactured and installed by Kensa Heat Pumps. Carbon savings over traditional air conditioning/boiler combinations have been estimated at around 50 tonnes per year.
