A UK startup has unveiled a new heat pump system designed to make switching from gas boilers faster, cheaper and far less disruptive for homeowners. Developed by Nusku, the system combines a heat pump and hot water cylinder within a single outdoor unit, removing the need for indoor equipment that would typically require space and internal modifications. By housing all key components externally, the design reduces installation time to a few days compared with longer timeframes associated with conventional systems.

The patent-pending unit is designed to deliver higher temperature output than some standard heat pumps, which may reduce the need to replace existing radiators when transitioning from a gas boiler. This could help limit both installation complexity and overall cost. The system is also being developed with integrated smart controls, allowing remote monitoring and adjustment to support system performance and energy use.

The product is aimed at two- and three-bedroom homes and has undergone initial testing at the Energy House facility at the University of Salford. Prototype units are currently being trialled in homes in Bristol, with further trials planned in other locations ahead of a proposed market launch in 2027.

Russell Murchie, CEO and co-founder of Nusku, says: “Our design will make it quicker and easier for people to replace their gas boilers and switch to renewable energy with a heat pump that meets all their needs.”
