Not every home or building needs the same system. Here is what each unit actually does, in plain English, with the numbers that matter — so you know what you're getting before we quote.
One quiet central fan continuously extracts damp, stale air from the wet rooms — bathrooms, en-suites, utility and kitchen — through ducting to a single unit, usually in the attic or a press. Suited to homes with up to six wet rooms (roughly 300m² / 3,200 sq.ft).
A single unit filters outside air and gently pushes it into the landing or central hallway. The slight positive pressure dilutes and displaces moisture-laden air, forcing it out through leakage paths and wet-room extract points. The go-to fix for condensation and mould in existing homes.
Two separate air streams — warm stale air out of the wet rooms, cold fresh air into the bedrooms and living rooms — pass through a plate exchanger in opposite directions. Heat crosses the plates; the air streams never mix.
A slowly rotating aluminium wheel sits in both air streams. As it turns it picks up heat — and a controlled amount of moisture — from the outgoing air and releases it into the incoming fresh air. Built in Sweden for BEAM.
An ultra-quiet, low-profile continuous-running extract fan for a single bathroom, kitchen or utility. One fan suits ducted-in-room or through-wall installs, with trickle, boost and high-boost speeds.
A decentralised heat recovery unit for one problem room. Stale moist air is extracted while fresh filtered air is drawn in, both passing through a heat exchanger inside the same unit.
An intelligent low-energy whole-house system designed for multi-housing developments. A central unit connects by ducting to extraction valves in the wet rooms, while passive fresh-air vents feed the habitable rooms.
Three elements: a power unit in the garage or utility, concealed 50mm ducting to wall inlets, and a lightweight hose with cleaning tools. Nothing is recirculated into the air you breathe.
