So do you buy the Viessmann Vitodens 100-W or not? It's the burning question on dozens of lips

Viessmann Vitodens 100-W Review FeaturesThe Viessmann Vitodens 100-W review won't fight for your attention. He's no show off. He'll blend in to the background, quietly confident that if you get to know him, he'll prove himself - and he will.

It's true, it's not as popular as a Worcester Bosch boiler even in spite of its components being made of spag bol, or as good looking as an Ideal Vogue but the Vitodens is a solid companion, a boiler with a good heart.

He's the type of boiler that'll pick you up from the airport at anti-social hours, give change to the homeless and put misplaced bird eggs back in their nest. The Viessmann Vitodens 100-W is loyal and dead set on saving you money, like a Labrador doing your accounts.

So with stats to topple the competition and a price point to better them, our answer would be - why on earth wouldn't you?
