Unvented Hot Water Cylinders

  • Home

There are two types of hot water systems - open vented and unvented.

Vented system is open to the atomiser and the pressure comes from a cold-water tank, usually installed in the loft. The pressure this system creates is not enough and very often requires the addition of a boosting pump, which increases the pressure for both hot and cold water.

The Unvented Cylinder’s pressure comes straight from the main water supply and delivers constant pressure to all outlets in the property. It eliminates the needs of cold-water tank and gives you more space.
