Keston designs rig for housing services

Individually designed rigs built by Keston for a large housing project combine a boiler, hot-water cylinder, underfloor heating panels and mains transformers, including electrical switchings for domestic appliances. The Duet rigs were developed with John Noad (Building Environment) Ltd of Braintree. They are compact in size and completely pre-plumbed, pre-wired and pre-piped for easy installation — including flow and return pipes to primary heating and the manifold box for the underfloor heating. The Celsius 25 gas-fired condensing boiler modulates between 7 and 25 kW and serves a Spa unvented hot-water cylinder and underfloor heating at around 35°C. The Duet rig is available in 125, 150 and 200 litre versions.
