At the heart of the building services is an Eco Thermia Duo 16 ground-source heat pump that extracts energy from the ground through three 200 m loops of pipework in the ground surrounding the pavilion using a water-glycol mixture.
The Duo design is a variant of Eco Heat Pump’s Diplomat TWS, the key difference being the provision of a separate hot-water tank.
The Thermia Duo has an integrated electric heating element with three power stages (3, 6 and 9 kW) in case additional heating should ever be required if not enough heat can be drawn from the ground.
Like all Thermia units, the Duo has weather-compensation control to ensure that the water supplied to the underfloor heating is never hotter than needed to maintain the required indoor temperature.
