The Rinnai are great space heaters. I’m in the HVAC sales industry and can attest to these heaters lasting 15-20 years typically; and with very few repairs needed along the way. I installed one in my garage recently (EX22) and it easily heats my 2 bay garage. My only suggestion would be to further simplify the control functions, especially with the timers. I’m in the industry and even I find setting and changing them a wonky process.
