I am trying to get to grips wth how many showers can be run off one source, as I have mentioned previously we are updating my lads' flat, by creating an ensuite. It would be far easier to have a combi boiler as space is at a premium, but I am told that such would not run two showers.
In my own house when they lived with us as kids we built an extension over the garage to give us two extra bedrooms with ensuites, making three ensuites and main bathroom. the 3 ensuites are served by a 5 year old Salamander CT 50 pump (1.5 Bar), the original pump lasted 14 years.
Today I decided to do a water flow test on each one at a time, bucket and stopwatch as advised on here. The individual ensuites all came out at 7 litres per minute. The main bathroom, that is purely gravity fed (head 5 feet max), came out at 5 litres per minute. The actual shower power in each case was more than adequate, not powershower, but for example in the main ensuite the shower reached from head height one end of 1700mm bath to the other at floor level a good arc. They never complained when they lived here.
I then turned all 3 of the Salamander showers on together, probably the first time this has occurred, expecting that the power would drop off considerably, but it didn't. Yes there was a small difference but still very acceptable as a proper shower. Arc went 3/4 down the bath.
My question if a combi pushes water flow out at 13 - 15 litres per minute why cant two showers be run off it at the same time, Am I missing something as my "tests" show that this should be possible. We are not looking for a blasting power shower, just perhaps the ability, if it occurs, that a quick shower by both in the morning can be achieved at the same time.
