Minimize that risk and impact with a LAROS energy recovery ventilation system! Our systems are one of your best ways to ensure good indoor air quality and minimise the health risks associated with mould and damp.

LUNOS decentralised energy recovery ventilation (ERV) systems provide fresh, clean air to your building, without losing valuable heat (or coolth).Decentralised systems do not require ducting, and are therefore much easier to install.

This makes them perfect for retro-fittings, or buildings that simply do not have space to install a centralised ducting system (for a new build, or existing home with ample access to a roof or floor cavity, centralised systems may be more suitable).

System Overview

The RAIS Bionic Fire is a modern, stylish fireplace with record-breaking heating efficiency.

The Bionic Fire’s dual combustion chamber design is based off a new system, which is used in highly efficient industrial fireboxes.

Its fully automatic air regulation makes for simple and effortless operation: once the fire reaches a sufficient temperature, the stove redirects the fire into the secondary chamber, giving the Bionic Fire its impressive double flame.

The RAIS Bionic Fire uses innovative industrial technology to create an elegant & environmentally-friendly residential heating solution.
