Unvented Hot Water Cylinders
Whilst vented hot water cylinders need a store of cold water, unvented cylinders get their water directly from the water mains.
The water mains feeds the hot water cylinder, this in turn heats that water, using either your boiler, or in some cases an immersion heater. Then when you need hot water it releases its store of warm water to your taps, the mains, in turn, refills the cylinder.
The Benefits are:
- No need for a store of cold water
- Higher water pressure
- Simpler plumbing
- Power showers without the need for a pump
