Navien Boiler Installation

Save substantial space.

Not only are they efficient but Navien boilers are much smaller and compact compared to your existing floor standing unit. 

improved steel heat exchangers

The condensing technology in the stainless steel heat exchangers saves energy, reduces green house gasses and lasts much longer than old copper systems!

low noise levels.

Very low noise levels – Installations in or near media rooms, recreation rooms or any living areas of the house are possible with these quiet running boilers.  These are perfect for smaller Toronto homes where it’s impossible to install the boiler far away from the bedrooms and recreation rooms.

and more...

low exhaust gas temps

The low exhaust gas temperatures produces means installation can use PVC, CPVC, polypropylene and stainless steel venting thus reducing installation time and costs for you! System can use 2" venting for up to 60 feet and 150 feet with 3" venting.

Environmentally friendly

Navien primary condensing stainless steel heat exchangers recover extra heat that would be lost in non-condensing boilers. The result is reduction in energy consumption, lower CO₂ emissions and very low exhaust temperatures allowing use of less expensive venting materials such as Schedule 40 PVC.

Energy efficient

Navien condensing boiler technology provides 95.0% AFUE, recognized by Energy Star as Most Efficient. These extremely efficient and eco-friendly units provide extra energy savings over a traditional floor standing boiler.

Optional naviLINK Wi-FI control

Optional NaviLink™ Wi-Fi control system gives you access to your NFB and NHB boiler from anywhere in the world.

High turn down ratio

Turn down ratio up to 15:1 on NHB and 10:1 on NFB – The sophisticated gas flow control system provides a high turn down ratio which reduces energy waste and excessive boiler cycling while also enhancing temperature control for DHW
