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:

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.
