Hi There,
We have an aging gas boiler which we need to replace. The hot water cylinder is on the ground floor, there is a cold water tank on the 1st floor and a header tank in our bedroom on the 2nd floor. The curent bathroom has a dribble for a shower. We removed the bath.
We are just installing a bathroom on the 1st floor and have a short (1.6m) slipper bath and a Aqualisa Aquatique 8" rose shower, and a sink. There is a kitchen sink and we'll probably end up with a cloakroom sink and utility room. The Dishwasher and Washing Machine are both cold fill.
Idealy we would like to go to a combi type sealed system removing the header, feed and hot water tank for space design reasons. The house has dormers in the roof, so no loft space. We can dedicate a 600ish square cupboard on the ground floor to heating/dhw requirements. It will be floor to ceiling and while we would like to get some towels/bedding in it, not a major requirement.
Condensing/HE is good and almost mandatory.
Aqualisa said a min 14lpm, though we'd like better.
We've seen the Worcester Greenstar Highflow 440 which is interesting and affordable. There are the Potterton/Baxi Powermax HE (85/115) which seem to be comming out arround the same price. We've also seen the Viessamann Vitodens 333 which is a bit on the tall side and comes with a high price tag, but also seemed to be a bit of a rollsroyce of a boiler.
I know the worcester drops to 11lpm and carries on after the heatbank is used, do the other two and are there any general comments / opinions / other options ?
Also looking for someone to install the boiler, though i'm happy to do a lot of the system changeover/removal etc. Huntingdon/cambs area
Thanks, Lee
