Now available from ESS (Environmental Site Supplies) is the Robur K18, an 18kW mini gas-powered heat pump that offers temperatures up to 65ºC for heating and up to 70ºC for domestic hot water. The K18 is aimed at larger or period domestic properties, and is also suitable for small commercial installations, such as church halls and care homes. A hybrid version, with an integrated boiler offers a 37kW output.
The Robur K18 is a high efficiency boiler replacement said to provide energy and carbon savings of 38% against a modern condensing boiler. It is a monobloc heat pump that requires no fridge work and simply connects to an existing heating main.
The K18 has fewer mechanical parts than electric heat pumps and so benefits from low noise levels. It satisfies demand in properties that are too large for electric heat pumps, or where higher water temperatures are required.
Kevin Pacey, MD of ESS, says: “It makes complete sense to use our established gas transmission network to deliver the energy we need for heating until such time that adequate renewable power becomes available. Gas heat pumps are straightforward for a gas-qualified plumber to fit and plumb, and are similarly priced to an electric heat pump.”
