Combi Boilers
A combi boiler is an all-in-one compact appliance that provides central heating and hot water to your home. Also known as a combination boiler, this compact device doesn’t require a separate water cylinder or storage tank.
Traditionally, combi boilers have been the perfect central heating option for smaller homes, due to the compact size of the boiler. However, with Navien UK’s latest combi boiler technology, which is in all our gas boilers, they are now suited to larger properties.
This includes our powerful NCB700 Combi Crossover, which can provide hot water to up to three showers simultaneously without losing comfort. Moreover, as gas combi boilers only heat the water your household uses, you will also pay lower energy bills in comparison to traditional regular boilers.
Our award-winning combi boilers are stocked in plumbing merchants and builder’s merchants nationwide and are fitted by our dedicated network of Gas Safe Registered installers in every region.
