How do I find out if the Navien NCB 24kw Boiler is suitable for my Home?
Combination or combi boilers do not require any additional components such as tanks in the loft, or hot water storage cylinders in the airing cupboard. This makes them great for small homes. They heat water from the mains, but they can’t handle more than one tap at once. Navien NCB Combi comes in four sizes. It is ideal for homes with only one bathroom.
You don’t want to make the wrong decision when choosing a boiler size or output. It’s best to have a Gas Safe registered engineer visit your home to give you a recommendation.
