Vaillant VCWGB 282 EH

Please advise if a pressurised tank can be attached with a combi boiler, i.e that the water is heated by the boiler instead of an immersion heater. the latter to be used as an emergency if installed.

I'd also need a manual and user guide for the above boiler.
Thanks all.

Like your VCW 282 GB I also say "EH" as in 'Eh I don't understand'

Lets have a go

Ok so you want your combi to heat a cylinder full of mains pressure water up. So for that you would need an unvented cylinder and an S plan set up to create a Hot water zone and a heating zone.

You want to be able to heat that cylinder up with an immersion heater. Well yes that could be provided.

You now have a problem and that is All your hot water would now be preheated and not instantaneous. Theres no easy way of switching from source to another for all your water draw off points.

But if you feed all the stored domestic hot water back into your boiler as if it was cold going in then the boiler will make up any shortage of heat as the stored water becomes depleted.

A little bit along the lines of a Ravenheat energycatcher set-up

I spent a while at the local theatre this evening. I think that Slug may have been down the pub or as the Government think down the Asda buying cheap booze.

Its quite feesible to heat an unvented cylionder from a combi boiler.

The DHW output from the boiler can be used to feed one outlet, often the kitchen.
