MY house already has a conventional boiler (with tank) supplying Hotwater and Central Heating for the whole house (inc bathroom) - it works well. I'm now considering installing 4 ensuites to the 4 large bedrooms. We plan to install a seperate Hotwater system. I need your advice on choosing a Combi boiler which will only supply hot water for these 4 ensuites? What power/type/brand/model should I choose? Many thanks!
It may be easier to instal electric showers.
I would suggest that you extend your current system to the new showers.
If you have a 28mm cold feed into the hot water tank and a 28mm supply from the tank you should not have a problem.
There is the possibility that the pipes may be overlong and the internal friction using 15mm pipes will result in unsatisfactory pressure, this can be solved by using 22 mm pipes to as close to the shower heads as possible.
Keeping in mind that the average shower time is six minutes, how likely is it that five people will choose exactly the same time to have a shower?
