Review:
"BAXI....TERRIBLE PURCHASE"
We purchased a Baxi Duo for our home in November 2014. We have had at least 7 service calls to repair/ replace parts. We experienced at least 13 times when the boiler stopped working. Some of the items that have failed: mixing valve, flow pump, burner sensor and pressure tank. (Sorry, don't remember technical names for these parts) We live in Vermont and the Baxi is used for heating. This unit is so undependable that I would have a very difficult time leaving my home for extended period during winter. The warranty does not cover us anymore so we are paying for repairs. I wish I had purchased any other brand

Review:
"Efficiency at its best"
An amazing small compact boiler that hangs on the wall that replaces the car-sized boiler that once was there. Super quiet. Been in for 3 years and not a hiccup. I will say if they're not Baxi certified don't let them touch it. These are their own animal and you wouldn't let the G.M. technician fix your Audi S5, so why let a flannel shirt plumber touch your state-of-the-art heating equipment.
