Our range of standard Direct Cylinders are designed to be heated by a single immersion heater.
Direct Vented Cylinders are fed from a cold water feed and expansion tank usually situated in the loft space within the property. These cylinders are generally classed as low-pressure cylinders due to the low static pressures better known as the working head.
The working head is determined by the distance between the feed tank’s water level, and the draw off point on top of the cylinder.
Available in various sizes from 96L to 512L.
