Top 10 Best Rinnai Heater Models — Be Prepared for the Cold Season

During the cold seasons, having a high-quality heater can be as serious as a matter of life or death. That is why we treated this ranked review with the seriousness that it deserved. First, we did a lot of internet research to decide which products were worth testing and which were not. Then, we compiled a team of three experts from the industry to evaluate the ten heaters we decided were worthy of a physical test. We had three rooms that were all three slightly different sizes.

We then gave each expert an accurate thermometer to keep an eye on the changing temperature of each room. We let the expert testers try each heater out in each different room to see how well it warmed areas of different sizes. We also asked them to rate the heaters on other aspects than performance such as energy efficiency, cost, design, and a few other things. Once they finished their rankings, they reported the final order to us to publish in the form of the above list.
