I dont know why you are asking about Radiant boilers.
They are a typical economy boiler which can give good service on a clean system.
They are not very well established in the UK and their sales volume is probably the lowest of the recognised brand names. They use independent service agents which can mean a quicker response then when staff engineers are employed.
Like many of the economy boilers they get a bad reputation because they are bought by builders and the unqualified and badly installed on dirty systems.
Very few CORGI registered people would want to fit them by choice. Is your "plumber" actually CORGI registered?
Yes he is - they just happen to be his fave boiler!!!!! I chose to go with Baxi as i'm ex British Gas sales and used to sell them as the Rolls Royce - but that was a few years back and I guess things change!!
