Have got water tank style boiler which is quite new.
Will I need to
a) get a combi? (and is that the heat as you go kind?)
b) will I also need some kind of megaflow or other style of pump?
Definitely want to be able to pour two baths/have two showers at same time although don't require power shower style avalanche.
We've got 1st floor bathroom and will have loft bath/shower room not directly above 1st floor one.
What do you have/reccommend?
