SUPER FAST RECOVERY hot water cylinders

For use where rapid recovery (re-heat) of the cylinder contents is required

The quick recovery cylinder has a special high performance heat exchanger which reduces boiler cycling and maximises the time the boiler can operate in condensing mode.

Its special coil enables recovery in as little as five minutes, assuming a correctly sized boiler is installed. The reduction in boiler cycling and faster recovery time combine to reduce the cost of producing hot water. The super recovery cylinder’s high efficiency coil and its ability to heat only the water you require means that a smaller capacity cylinder can be used. This makes it the ideal replacement choice where space is an issue but rapid reheat times are still required.

The cylinders 35mm of high efficiency EnviroFoam insulation further reduces standing losses – particularly beneficial during summer months.

Positioning tappings to your specification does not normally attract a supplementary charge

When sizing a cylinder remember the stated dimensions do not include the thickness of insulation. You must add the thickness of insulation to the cylinder dimension to obtain the finished size. This is most important if the cylinder needs to pass through a doorway or access hatch. Make sure you have enough room to make connections and service immersion heaters.
