Hi friends
I m Zmicer.
I am plumber heating from Minsk Belarus.

let me show you my last project. I wold like to get your opinion.
One my customer has a Сombi boiler in his house, but the Combi boiler does not give enough hot water when he needs a bathroom.

I have a plan "B" for him to solve the problem.
Please look at the circuits.

Plan "А" is works now, but the Combi boiler does not give enough hot water when my customer needs a bathroom.

What do you think about it?

Install a regular unvented cylinder on an s plan. Not how you've got it on the drawing.
Thank you for the reply.
But you forgot to say exactly how otherwise will need to install a unvented cylinder ?
And if possible, share a link to plan.
I'm going to use a conventional electric boiler. 100 liters. Of course I want more then 100L, but there is not much place in the house.

this is an update on the next picture.
I want to do a layer-by-layer water heating cilinder.

It's no so good idea, but i need to change the GAS project and put Vitopend 100 to trash (
 
I’m confused...

You say and electric boiler but you show a gas fired boiler with flue and gas supplies.

Fit an indirect unvented cylinder and have the primary heating circuit zoned off to supply heat to the cylinder via the coil and then mains pressure hot water to the domestic hot water circuit.
Instant hot water from combi can still be used to provide for kitchen sink and perhaps bathroom sink!
