Comfort Flow

Exclusive built-in recirculation system included on all NPE-A models.

Navien ComfortFlow® is the first and only system that incorporates a built-in insulated buffer tank and recirculation pump.

comfortflow-unit

The buffer tank eliminates the “cold water sandwich” effect and issues of minimum flow rates commonly found in other tankless water heaters. The recirculation pump saves on water bills by reducing the time to get hot water. When activated, the optional ComfortFlow mode results in additional energy usage.

ComfortFlow® recirculates hot water through supply lines, eliminating wait time for hot water.ComfortFlow

We just had a gas fireplace installed by Cozy Comfort Plus. What an incredible and seamless process this was - beginning to end.

We met with a few companies, and loved the professionalism and communication with Brian. He was thorough in his explanations, took his time to answer all our questions. We were so impressed that we knew right away this was a company we wanted to work with.

The installation was seamless! A team of three people (Jason, Amir, and Hamid) came on time and got straight to work. They were friendly, efficient, and left the space spotless!

Had we known that switching from a wood fireplace to a gas one was this easy, we would have done it years ago!

We would highly recommend Cozy Comfort Plus to anyone wanting to install a gas fireplace!!!

So happy we did our research and ended up working with these guys!

When my furnace broke down last winter, we were without heat for two weeks while the HVAC company sourced the parts from the US. I wanted to install a gas fireplace insert to replace my existing gas log set and to act as a backup heat source (e.g. furnace breaks down again, no power). I had a number of questions about the various gas fireplace inserts (e.g. size and fit in my old fireplace) and I contacted several HVAC companies.

I found that Brian from Cozy Comfort Plus to be the most helpful and he also gave me the best price. I was home at the time and I saw that the Cozy team did a great job installing the gas fireplace insert (e.g., assembling and fitting the insert, bending and capping the chimney, etc.). If you are looking for a gas fireplace insert, I would highly recommend that you give Brian a call.

We purchased a gas insert for our home from the Cozy Comfort Plus. The whole process was super smooth and easy from the very beginning. Brian was very knowledgeable and professional. He patiently guided us through different options we had. The installation crew were also super friendly but at the same time professional and serious about their work.
I would definitely recommend them to anyone who is looking for a satisfactory experience.
