Vented Hot Water Cylinders
In simple terms with a vented hot water cylinder you have a store of cold water usually in the loft that feeds the hot water system.
The hot water system is often heated by a gas or oil boiler. Some renewable systems, such as Solar Thermal, can be used. The pressure is gained through gravity, so the height of the cold water store above the hot water cylinder creates the momentum that pushes that water out of your taps.
The benefits for this type of system are:
- Easy to install
- Low maintenance
- Simple mechanism
The potential drawbacks are:
- You have to have a cold water store, usually in the loft
- Hot water flow rates may be low especially if pipes are not adequately sized
