ArchimedeWall Mounted Booster Set Inverter

It's an inverter-controlled pressure booster that maintains consistent water pressure and flow when mains pressure is too low or when supplying from a break tank or borehole. The built-in inverter varies pump speed to match demand, so pressure stays steady whether one tap or several outlets are running. This makes it ideal for homes, flats or small commercial premises with weak or fluctuating mains supply.

Sizing comes down to two figures: the flow rate you need (litres per minute, based on how many outlets could run simultaneously) and the pressure boost required to reach your target bar at the furthest outlet. As a guide, a typical 3-4 bedroom house with two bathrooms needs a higher flow rate than a single flat. If you're unsure, tell us your outlet count, pipe run and current pressure and we can help you match a model.

No — running any booster pump dry will damage the impeller and seals over time. The Archimede units include electronic dry-run protection that shuts the pump down automatically if inlet supply is lost or a tank runs empty, then resets once flow returns. This protects the pump without needing a separate control panel or float switch in most installations.

Inverter-driven booster sets are notably quieter than fixed-speed pumps because they ramp speed to demand rather than cycling on and off at full power. That said, they should still be wall-mounted on a solid surface away from bedrooms where possible, ideally in a utility room, garage or plant space with access for servicing. Some structure-borne noise is normal, so avoid mounting directly onto stud walls backing onto living areas.

Yes — if you're boosting directly from the mains, you'll need to check with your local water company, as some regions restrict direct mains boosting and require an intermediate break tank instead. Installation should also comply with the Water Supply (Water Fittings) Regulations to prevent backflow and undue strain on the public network. A qualified plumber or installer can confirm what applies to your supply before you connect the unit.

Most Archimede wall-mounted units run on a standard single-phase 230V supply, though it's worth checking the specific model's rating before wiring in via a fused spur — this should be done by a qualified electrician. Maintenance is minimal: periodically check the inlet strainer for debris and confirm the pressure vessel (if fitted) holds its precharge. Servicing every year or two keeps the inverter and seals in good working order.
