Which Boilers do they Offer and What do we Recommend?
Navien has a few boiler systems available and some which are multifunctional systems. We will go over their main boiler systems however we will make a special mention of their current, most advanced new systems as well.

Other Systems:
Navien’s other systems include the above Condensing NCB in System and Regular boiler types with similar features. The other water heating only systems are currently hard to find in the UK so we haven’t included them in the review today.
We will however be looking at the Energy Generating Stirling Systems:
The Navien HYBRIGEN SE- An Energy Generating Revolution:
The Navien HYBRIGEN SE provides an innovative solution to the global power supply crisis.
This is the next-generation green technology that reduces fossil fuel consumption and greenhouse gas emissions!
The Navien HYBRIGEN SE uses Navien’s patented m-CHIP for home use that produces electricity by driving a stirling engine.
The heat generated in the process is used for heating and domestic hot water, so it recirculates friction heat while generating electricity!
The dual energy system provides both heat and electricity from one appliance and does not rely on the sun or building orientation to generate power for your home, just a gas supply.

What’s the Verdict?
Although the range of Navien is quite small, they are actually one of the world’s biggest combi boiler producers. With affordability, high quality components, and innovative features (and a 7 year warranty) they are a pretty good deal in our opinion.
