Hi all,
Our 15 year old boiler has finally given up the ghost and so we're getting quotes for a new Combi boiler to take its place.
We've just had a visit from an engineer who is an accredited Viessman installer. He said they're great boilers which have a 10 year warranty. I hadn't heard of them before so I wondered what everyone thinks of them? Would you say a Vitodens 100 35kwh is better than a Worcester Bosch 42cdi (the other one we've been offered)?
The 2nd thing is that the aforementioned engineer has also said that we don't need to power flush our system before installing a new boiler. He said it isn't required for the Viessman warranty and we would just be wasting our money - he also said we don't really need a magnaclean either. He has included a flush of our system using mains water in his quote.
We're still planning to get a couple more quotes but I'm really confused. What is the best brand and should we powerflush and get the magna clean installed?
The Viessmann engineer has great feedback on checkatrade (almost 10 out of 10 from over 140 reviews) and I was impressed with him but I'm very wary about his view on the power flush and magna clean issues
