The main part of the dwelling is fitted with a Nibe Fighter 1330 22kW ground source heat pump, which draws energy via a 6 x 100m bore-hole matrix.
The energy sourced from the ground is stored within a 200 litre buffer vessel for heating distribution, within a under floor heating system, set in the floor screed to the ground and first floor. The second floor benefits from an Uponor Unipipe system 12 (15mm floating floor panels combining a 12mm pipe due to height restrictions). The hot water is provided via a 500 litre VPAS cylinder linked to solar collectors.
A Mechanical Ventilation with Heat Recovery (MVHR) system was installed throughout, which complemented the designed low air permeability of the building. The MVHR system incorporated comfort cooling to all bedrooms, which utilised an existing ducting system.
The Swimming Pool is heated continually by an additional Nibe Fighter 22kW ground source heat pump, which draws energy from 6 x100 meter bore holes. This energy is then distributed to a 200litre buffer.
