Worcester have further expanded their renewable technologies to include an 11kW system heat pump together with four combination ground source heat pumps and two new Greenstore cylinders.
The introductions follow the introduction of their System range of Greenstore ground source heat pumps in summer 2006,
The 11kw system model joins the existing Greenstore 6 system, 7 system and 9 system ground source heat pumps whilst the combination models, which are also available in 6kW, 7kW, 9kW and 11kW outputs, were introduced in early 2007 to suit homes that don’t have the space to accommodate a separate cylinder for hot water storage.
Completing the package of ground source heat pump solutions available from Worcester, the Greenstore Cylinder series is available for installation with any of the System models available in the range.
Worcester’s Greenstore cylinders and are available in two sizes – 180 cylinder and 280 cylinder. Both feature a tank in tank design to achieve the larger surface area required for heat pumps and include a secondary heat source coil, making them compatible with Worcester’s Greenskies solar system too.
Importantly, the Greenstore combination series of heat pumps and the Greenstore cylinder range have also been fully approved by independent testing body KIWA, to section G3 of the building regulations, which means they fulfil the legal requirements for unvented hot water storage.
The G3 regulations have been devised as the method to ensure that products which store in excess of 15 litres of hot water are equipped with safety devices capable of preventing the water from exceeding 100ºC. And Worcester have taken the step of specifically approving the products they bring to the UK and are the only supplier of combination heat pump products which include the mandatory G3 approval.
