When it comes to water heater performance it’s all about the output.
The NPE-S condensing tankless water heaters are so efficient that they outperform much larger capacity non-condensing competitors. More output for the money, lower installation costs and lower operating costs for customers makes it a smart choice.
Front Panel Control Center
Common vent up to 8 units
Cascade up to 16 units with Navien Ready-Link® technology.
Optional Wi-Fi remote control system
NaviLink makes it easy to communicate with your Navien systems anywhere internet service is accessible. The NaviLink module attaches easily to any new or existing* Navien NPE Series tankless water heater, NCB-E Series combi‐boiler and NHB Series boiler.

From installation to maintenance, Cozy Comfort Plus Inc. provided us with prompt, quality service. It took under a day to install our Mitsubishi split-type air conditioner in May, 2021. This week, they attended to cleaning our unit’s filters in less than a day’s notice. The technician explained how to remove, clean and reinstall the filters ourselves which will save us money down the road. I highly recommend Cozy Comfort without reservation.

Steve NishimuraWe were looking to replace A/C, furnace and water heater and had a number of companies provide quotes. Brian of Cozy Comfort Plus was the most engaging person we met and most importantly, the person we trusted the most. His price was very competitive and we decided to go with him. His team of four men, led by Mir, came in and got the job done in one day. We are very happy with the Lennox equipment and the professional installation job done by Cozy Comfort Plus.

Kenny LeungBrian once again helped me with my project. Before I have installed a gas fireplace and this time I have installed an LG heat pump with 3 indoor heads. We had an amazing experience with Brian and his team for both projects from quote to installation. Brian is experienced, patient, reliable, and provides great friendly service. He’s also tells very interesting life stories which makes enhances the whole experience. All my future business is going to his company. Thanks again Brian!
