Live project · Site photographHeating, plumbing and ventilation. Coming together on site.
HMS is delivering air-source heat pump installation, plumbing and ventilation for The Tawny, a new-build home in Smarden, Kent. The renewable heating package combines a Grant Aerona heat pump, hot-water storage and underfloor heating across both floors. Mechanical ventilation with heat recovery, water services, bathroom installations and above-ground drainage complete our scope.

Underfloor heating.
Part of the plan.
Explore the pipework, underfloor heating circuits and plant connections in the ground-floor design illustrations. As the project progresses, final routes and manifold positions are confirmed for installation.


04 / Our scope
The systems behind the home.

Heat pump installation & hot water
Supply and installation of a Grant Aerona air-source heat pump and Grant unvented hot-water cylinder, with a volumiser, hot-water circulation pump, insulated pipework and freeze protection.

Underfloor heating
Screeded underfloor heating on the ground floor and a spreader-plate system on the first floor, with manifolds and independently controlled heating zones.

Heat-recovery ventilation
Supply and installation of the mechanical ventilation with heat recovery system, including the unit, ductwork, supply and extract valves, terminals and associated fittings.

Domestic water services
Incoming above-ground mains water connection and hot and cold-water distribution throughout the home, with insulated pipework, isolation valves and hot-water return pipework.

Bathrooms & drainage
Installation of client-supplied sanitaryware, kitchen and utility sink connections, and above-ground soil and waste drainage serving the scheduled fittings.

Rainwater distribution
Recycled rainwater distribution pipework to the designated outside taps and WCs. The rainwater equipment and below-ground works are provided by others.
Project delivery
From installation
to handover.
HMS’s delivery package includes pressure testing before pipework is concealed, heat-pump commissioning and functional testing, and ventilation commissioning and balancing. Commissioning records, operating manuals and warranty information form part of the handover package.
Heating controls, thermostats and associated accessories are supplied by HMS for installation, wiring and final electrical connection by the on-site electrician.
