This detached rural home has been constructed to Passivhaus standards of
insulation and airtightness around the structure of an Atcost barn. The
owner involved us at an early in the design and construction of the building
which enabled us to ensure that the heat pump pipework and controls are
integrated into the fabric of building as seamlessly as possible. At the
outset we prepared a room-by-room heat loss analysis which was used to
assist in the design of the build.

We installed a 6kW NIBE F2040 on a purpose-built plinth a short distance
from the house, connected using a continuous length of pre-insulated
Microflex heat main to the hot water cylinder and buffer tank in the utility
room. Hot water is supplied from a 300L NIBE Megacoil cylinder. A UKV
40L buffer tank connects to a UFH manifold.

To achieve enhanced operating efficiency the system is weather
compensated, which improves efficiency by ensuring that the flow
temperature output by the heat pump is adjusted to match the outdoor
temperature. The NIBE MyUplink facility provides remote monitoring which
enables us to provide enhanced technical support.
