Which Combi Boiler Brand is the Most Reliable?

In chilly conditions, few appliances are more valuable than a functioning combination (often shortened to combi) boiler. This device can be a reliable and hassle-free way to keep you and your family warm during the winter months. A ‘combi’ boiler is a high efficiency water heater and a central heating boiler in one single unit.
To reap the benefits of a high efficiency water heater and a central heating boiler, you need to choose the right brand. We have researched the best combi boilers currently on the market, and the following brands are the most durable and reliable:

Boiler

Rinnai

As an industry leader for tankless water heaters, Rinnai is quickly taking the lead in the combi boiler space. Over the years, Rinnai has released several series of models that can be hung up on walls to meet all your heating and hot water needs.
A Rinnai combi boiler contains three heat exchangers, and the largest one heats the water to your specified temperature level. The second functions to preheat the incoming water and take excess heat out of the exhaust gases. The third heat exchanger isolates your portable water system, allowing you to apply glycol in your heating system.
Rinnai combi boilers combine tankless water heaters and a furnace into a single unit. When the furnace is turned on, the fan begins pushing hot air through the duct work. When you turn on the tap, the combi boiler immediately senses a need for hot water and prevents it from flowing to the furnace. Through the secondary isolated heat exchanger, the hot water then flows to the tap. As the tap is shut off, the combi system will direct the water back to the furnace.

Navien

Navien is a Korean combi boiler brand that focuses on leveraging innovation to improve the performance of their boilers. They are also known for being easy to use, adjust and operate. Their boilers supply hot water for your cleaning, bathing, and cooking needs, as well as to heat your home.
All Navien models have the ENERGY STAR® certification and an AFUE rating of 95%. Navien’s boilers are more efficient than traditional ones. They will trap and recycle some of the heat that would otherwise have been lost with a conventional boiler. This results in significant savings when compared to less efficient brands. Plus, Navien combi boilers are affordable and compact, making them a perfect option for most homeowners. If you purchase a Navien combi boiler, you will benefit from high flow rates and low noise levels, and you’ll also have multiple venting options for installation.
Moreover, the latest Navien combi boiler models can be connected to NaviLink; this allows you to operate the boiler remotely from anywhere around the globe.

    Brian and his team were very professional, the customer service was excellent and their prices are very competitive. One month after the installation of our tankless water heater, everything is running and operating as promised! My only recommendation is to try to offer credit card payment options that do not entail going to their office in person. Other than this small inconvenience, this service was superb. Thanks Brian!

    We 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 😀👍

    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.
