I'm trying to work out whether to get a Vaillant Turbo Max, or a Aqua Plus.
The Plus seems to be the same as the Turbo Max, but with a 15-litre water
store. The blurb says:

"...unlike other wall-mounted combis with stores, its 15-litre store ensures
there are no G3 Building Regulations installation restrictions. "

I suppose my question is a) is this water store worth the extra money (and
space compared to the Turbo Max) and b) what's this about G3 regulations?

Thanks for any tips.

Part G3 of the Building Regulations is all about domestic hot water
production and storage.

You can look it up at www.odpm.gov.uk under Building Regulations and
Approved Documents

Installation of a pressurised hot water system is controlled under
this part if the storage is greater than 15 litres. There are
specific requirements for safety in the design of the system, and the
installation must be done by a trained and approved sealed system
fitter. DIY is not possible.

For the purposes of this part of the Building Regulations, a system is
exempt if it has storage of 15 litres or less. An approved fitter
can self-certify the installation.

However, all boiler and DHW installations are now controlled under the
energy efficiency part L1 of the Building Regulations. For a
professional installation, a CORGI fitter can self certify the boiler
installation. If you want to DIY it, then you need to contact
Building Control at your local authority and organise a building
notice.

Whether 15 litres of hot water in the boiler is useful is a moot
point. All that it will do is give you water slightly earlier when
you run the tap and for small amounts may not fire up the burner to
replenish it.

To start to get a real benefit from this technique, a larger store
would be needed, which some boilers have, but then you are looking
more at a CPSU type of device - i.e. floor standing, washing machine
sized. These are professional install only of course.

Ah - thanks. All clear now. So it seems I can file the Aqua Plus with it's
15 litre store under "not worth the extra money."
