Loft installation of a combination boiler is getting very popular with many people. Wireless controls make this easier to install and the flue plume doesn't cause a nuisance up near the roof. I fitted a Baxi 28HE DuoTec recently which comes with a built in frost stat, very handy for a cold loft.

We used Tony to do our shower room and got him back to do our boiler. We wouldn't use anyone else.
