Hot water pressure for 2 showers

[xdrive]

Hi.

I'm having 2 bathrooms. What's best way to provide got water at same time?

Have combi boiler.

Will I need a pump? Don't really want electric shower.

Thanks

You can't fit a pump on the mains (combi system) above 12l/min which wont help much. Using the showers one at a time or fitting an electric one are the easiest options.

The less easy option is to install a hot water cylinder to supply one or both bathrooms. You can keep the existing combi boiler.

What size is the combi boiler? There are Raindance shower heads which are aerated consuming 9 litres minute mixed hot an cold. So a good sized combi can just about do two of these showers.

Best have a full bore main stopcock and a dedicated 22mm pipe from the stopcock to the combi. A tee at the main stopcock to all other cold outlets. Piping up the hot and cold water pipes properly is important in any mains pressure system. Shower is king - all pressure/flow must be directed to the shower. Balancing the hot and cold system by pipework, aerated taps and outlet flow regulators is essential.

Really depends on what kind of showers you want to have - skin tingling - massage type - overhead rain shower - basic washing - etc.

That is a good point. The aeration of the Raindance at 9 litres a minute, mixed not & cold, give the impression of a drencher. I have had combis fitted with two Raindance showers with them coping.
