Unvented Cylinders

Efficient home heating

Built on quality and performance, with one of the widest ranges of models available you can be sure there is a model to suit.

The Cyclone brand is noted for its attractive grey metallic finish. Manufactured with high-grade duplex stainless steel, 316L grade stainless fittings, and coils. For heat pump ready cylinders our coil quality sets us apart. Unlike most cheaper brands on the market, the Joule Cyclone High Gain range of cylinders uses high recovery smooth tube coils for optimal performance. No other coil type on the market today offers the same transfer rate as a smooth stainless tube.
