Heating system help

[b21playa]

Hi all

Need a few heating system for the house to replace the old boiler.

In total there will be 16 radiators of various sizes, 1 wetroom shower and another shower that will be electric.

Is it possible to run this of a combi boiler like a worcester bosch 42cdi, and will there be enogh power to the shower?

Also what could be the alternative?

Thanks

That would be fine if thats what you have got.

However, the performance will depend on the mains water incoming.

You will need a dynamic flow rate of at least 24 li/min if you are going to get full performance from both showers at the same time.

Thanks for the reply

Would a Vaillant 937HE be better due to seperate 15l storage?

also as the ground floor is concrete, what would be the best way to run pipes so you can see them?

The 937 will give 20l/min with a suitable incoming mains pressure and flow rate.

Unless you want the expense and/or bother of cutting up your floors then surface mounting the pipes will be the easiest answer.
