Navien Condensing Technology To explain ‘Condensing Technology,’ imagine condensation on a glass of ice water. This effect is created within our condensing heat exchanger (latent heat exchanger) from the incoming cold water cooling the hot gases inside the unit. The state-of-the-art stainless steel condensing heat exchanger is designed to capture the latent heat of water vapour in the exhaust gases that would normally escape through the flues in conventional boilers. By using the latent heat, Navien NCN Condensing Combination Boilers can achieve the highest efficiency level, providing one of the most economical and reliable combi boilers on the market. All the more reason to switch to our SEDBUK Band A rated Navien NCN boilers is they maximize energy savings and minimize greenhouse gas emissions.

Highly Efficient, Highly Reliable,

Condensing Combination Gas Boiler

Where Technology meets Ecology Navien products are widely known to be associated with quality and reliability. When designing products to meet customers’ needs, we only select the finest components. That is why Navien NCN Condensing Combination Boilers are produced with stainless steel to eliminate corrosion and guarantee long life of your appliance.

Navien NCN Condensing Combi Gas Boilers The Navien NCN boilers generate hot water on demand for both your central heating and domestic hot water; therefore there is no need to install a separate hot water cylinder which takes up valuable space within your home. However if large amount of domestic hot water is required, the boiler can be configured to provide instantaneous hot water and at the same time control an indirect cylinder. This feature also enables you to connect the Navien NCN boiler to a solar cylinder and benefit from solar technology.

Key Features The SEDBUK Band A rated Navien NCN boiler is the ultimate choice in today’s world of high energy costs and environmental preservation.
