Thanks,
I already have the boiler in place, i have added a loft room with an en suite, which i am trying to avoid using a electric shower for. It is a Baxi Duo Tech 40 HE A, the waterflow seems ok when i run the downstairs tap, but it looses heat when there are two feeds running, which i suspect would happen if i added an additional shower. Is there anything i can do to avoid this happening?
Ben
