Combi - hot water without heating connected?

[Scott_D]

I am changing a heat only to a combi for a friend - Worcester combi
They dont want to be without hot water over night as they have a baby and im not likely to get it up and running in a day.

Can I do a temporary link up of the flow and return for the night or could it damage the heat exchanger or pump etc.

Just leave cylinder in with emersion element

or install an intergas which can run hw without a heating circuit

you can link the flow and return up if you need to, the longer the link the better. Dont forget your spoonfull of inhibitor 🙂

Thanks for the suggestions
They want a Worcester, not my choice.
The immersion is dead.
If I link them I will power flush and inhibit:61:

tell them to buy a decent boiler, they want want it breaking down to quickly, less to go wrong with an IG

do they want a new boiler or not, tell'em to go stay with the inlaws for one ****ing night

I hate unreasonable customers

What's wrong with a kettle? Or a saucepan. Tell them to do one. Would you actually need any pipework if just overnight?

Baxi use side of DHW plate as a bypass. So fine to shut off ch!

Ideal logic work fine for a few days, but supposed to have 10% of boiler capacity uncontrolled as a bypass.

Valiant no good though without ch.
