How can I determine if the Navien NCB 34kw Boiler suits my Home?

Combo or combination boilers don’t require additional components like tanks in the loft or hot water storage containers in the airing cabinet. They are great for small homes. They heat water from mains but can only handle one tap at a time. Navien NCB Combi comes in four sizes. This is the ideal choice for homes with just one bathroom.

When choosing a size or output boiler, you don’t want to make a mistake. A Gas Safe registered engineer should visit your house to make a recommendation.
