The Navien NCB 33kW is the most powerful boiler in the NCB system boiler range. With an output of 33kW for central heating, this system boiler is ideal for medium-sized homes with up to 20 radiators and 1-2 bathrooms. However, for smaller homes with lesser demand for hot water and central heating, we would recommend looking at Navien NCB System Gas Boiler range. This boiler range includes 20kW, 23kW and 28kW
In addition to this, thanks to its high-efficiency rating of 93%, the NCB 33kW is also known for being a highly reliable and efficient system gas boiler that could potentially help you to lower your energy bills long term, depending on your current boilers efficiency rating.
The boiler unit itself has been designed to be compact and lightweight so that it can be wall-mounted in the space of your standard kitchen cupboard, out of sight, out of mind. However, it is important to remember that although system boilers are great for homes with a high demand for instant hot water, you will need an additional hot water cylinder installed during your boiler installation in order for your heating system to perform correctly.
These hot water cylinders are often installed in an airing cupboard or similar-sized space in your home. For this reason, system boilers are not recommended for homes with limited space. On the plus side, if your home has limited space, the Navien NCB range is also available as a combi boiler, so there is an option for everyone.
