Pro’s

This is a wonderful, reliable boiler giving efficiency, performance and reliability. With a stainless-steel heat exchanger and has been designed and built with a very long life in mind. It is compatible with Vaillant’s ebus controls and weather compensating controls giving a further increase efficiency by 4%. Modulation range of 1:6, it has won Which? Best buy and is very quiet. This boiler is good for small, mid-size and larger homes, however for small homes with a combi boiler and low hot water consumption might be better served saving some money and going for the pro.

Con’s

Very hard to fault.
Cost – however it does give long term value for money
It does not fit in a standard kitchen cupboard.
It is not possible to fit pipework behind the boiler without fitting a frame (this cost a little extra and makes the boiler deeper).

Opinion

Love it, fantastic boiler, just wish it was a little cheaper.
