Unvented cylinder in a vented system

[jakefouro]

Hi All - have to move location of my vented hot water cylinder so am taking the opportunity to install a solar panel. I initially planned to change to an unvented system as most of the pipework is in the attic and got my hands on an unvented stainless steel dual coil 250litre tank at a good price. However now having second thoughts and am wondering if I can use this tank in an unvented system. It is a little taller than the height of my current cylinder but there is scope to raise the cold water tank in the attic. Thanks in advanced.

You can use an unvented cylinder in a vented installation.

An unvented cylinder should be installed by a qualified installer in the UK. I would have thought the same applies in Ireland too.

Thanks Tony - does that mean that if if you are installing a pressurized cylinder in a vented setup you would still require a qualified installer?

yes a unvented cylinder req an installer with a G3 cert & if you plan on using the solar panel to heat it you will need a solar cylinder with two coils as well

Yea its a solar cylinder with twin coils and temperature sensor probes etc. Thanks again.

Anyone can install a vented cylinder! Even if its specificed to be used as an unvented.

Solar is interesting! Perhaps I have a mental block but cannot think of any reason why anyone cannot fit that too. Not that I would advise anyone to fit it without the appropriate training.
