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

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.
Jon ConwayWe are so happy with the service, support and product that we received from Cozy Comfort Plus. Brian was incredible to work with, he took the time to understand what we were looking for and helped us with the designs and what the best fireplace for us might be. He is extremely easy to work with, very easy to communicate with and so fast and responsive!
Everything happened exactly on schedule and as planned. It was a well oiled machine!! The crews that were here to build everything were super friendly, kind, courteous and knowledgeable.
Highly highly recommend to all 😀👍

Andrew P.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!
