Mains supplied hot water cylinder

[mrgrimsdale]

I'm contemplating supplying my hot water cylinder from the mains to improve the rate of flow to the shower. How does one vent the cylinder, or doesn't it get vented?
Thanks.

Good plan, although it might be an idea to search this forum for advice to similar threads before you go ahead.

not if its one of these you won't be.

You'd need an unvented cylinder and the whole kit of safety devices that are supplied with it.
You also need a trained installer to install it.
Don't even think about trying to modify a conventional vented cylinder or installing an unvented cylinder yourself. There are innumerable pit-falls, most of them involve flooding your house.

Or causing a nice, pressure-induced explosion

Just looked into that............1 see what you mean. Plan2 then. Are those venturi showers any good?

There are a number of approaches to get mains pressure DHW.

1. A high flow combi. (probably the best approach as it will use less gas)
2. A thermal store (can be DIYed)
3. A heat bank (can be DIYed)
4. A Venturi shower (Idea Standard Trevi Boost) for high pressure showers and low pressure everywhere else.
5. A DPS shower Booster or heat bank conversion box that converts an existing cylinder to a heat bank (can be DIYed)
6. Unvented cylinder (needs an approved installer, an annual service and can explode if things go wrong)
7. Shower coil cylinder (this has a coper coil in the top of the cylinder for high pressure showers)
