Unvented Systems
As we have said an unvented cylinder is supplied by the incoming main. When you open your tap, that high pressure cold water enters into the unvented hot water tank at the bottom, forcing hot water out of the top outlet and to your taps.
Advantages:
1. Pressure is much higher on all outlets.
2. No loft tanks which reduce risk of contamination and legionnaires
3. No pipes in the loft so no frozen pipe risk.
4. Very high heat recovery rate after use. Typical warm up time 15-20 minutes.
Disadvantages:
1. The hot water pressure will only be as good as your incoming main, however this is fine for most people.
2. You cannot fit shower pumps on mains water supplies. However you shouldn’t really need to.
3. When feeding multiple outlets the pressure can drop. This also applies to vented systems. On unvented systems it can be due to a small incoming main pipe (15mm for example). To overcome this on an unvented system, you need to install an ‘accumulator’.
