Rated 2 out of 5 by from Dont Bi - Asi I bought this in lockdown and it was fitted by a Gas Safe plumber. Continually failed and not even their recommended Biasi engineer could get it working. I need a reliable boiler, this isn't it. Warranty doesn't apply as my plumber didn't register it and company have washed their hands of problem. I am forced to take it out (only been in place for 11 months and hardly done any any work) and putting a more recognised name in. From my experience Id have to recommend that you avoid using this brand.

Does this come with a thermostat?

Asked by: sidav
Hi, thanks for your enquiry. Because of the different types of thermostats on the market all boilers come supplied without, so you can chose what type is best for your system and lifestyle. It is possible to fit either a volt or volt free version to our boiler.

What accessories go with this

is flue included
Asked by: astrorover
Hi, Thanks for your enquiry. The boiler is priced within the catalogue as boiler only because of the fact there are many flue options available. The standard flue has the following SF Code 61069. You can run the horizontal flue up to 10m and the vertical also up to 10m. Each 45 deg elbow added to the system reduces this maximum flue length by 0.5m and any 90 deg elbow reduce the maximum flue length by 1m.
