Using a combi boiler as just a water heater.

[md68]

Never done this or even tried it before but can i use a Baxi Duotec (ver 1) just as a water heater, flow and return turned so my customers can have hot water whilst I re pipe their system ?

As a temp measure why not? Never done it myself either! Only concern would be whether or not the boiler 'dumps', on overrun, excess latent heat into the radiators before switching off? I don't know the answer to that one or took notice to be honest

Baxi fine for few days. Uses side of plate as bypass. Pump over run may be bit longer but fine. If it's going to be longer i .e weeks or months I would make loop through old cws full if cold water . Then cws will cool ch water as it flows through, not really needed but if it's a 40 and they are running 3 baths and them a few showers boiler might get a bit tired!

it's a 28 kw if that makes any differance

u can use an intergas combi as a water heater as long as you like, only needs a couple of button pushes to do so

Should be fine, as has been said, it uses the plate as a bypass.
