Hi all, trying to put in a cheap RC unit for my rental. According to what's available in store, I'm deciding between kelvinator and Rinnai 2.5kw. However, I noticed Rinnai is using the older R410A gas, while Kelvinator is using the "newer" R32 gas. I heard from someone R32 is more energy efficient and more robust? Is that true? Would aircon with R32 gas last longer?
Appreciate your tips & advice. Thanks!
Yep, I would be looking at it’s cooling capacity and it’s power consumption over what gas it was using…
R410a is a mix of R32 and I think R125(?) as to lower the likelihood of flammability. R32 is flammable.
The biggest benefit of R32 is its environmentally better for the planet then what R410a is. R32 is about 1/3 the “Global Warming Potential” of R410a
Outside that, the fact that R410a is made up of R32 would suggest that they would perform pretty much the same or similar. The push behind using R32 in some systems would come down to a more environmental choice than a energy efficiency issue.
Global Warming Potential
It's all about potential damage, and never actually damage.
While the gas is sealed inside the air conditioner then it's not acting as a greenhouse gas.
If the gas is released into the atmosphere when the air conditioner is disposed of, it will act as a greenhouse gas.
mate, its a rental you don't have to pay the electricity bills the tenants do. get whats cheaper they should be glad you have anything at all in there (and pay a little extra in rent to cover it)
I wish, the old one broke down. So gotta replace, else they gonna go crazy over summer. Unfortunately it's renters market, so I better do my best to keep them
Air conditioners with R32 refrigerant will have about the same electrical efficiency as those with R410A refrigerant gas. Perhaps they would be about 2% more efficient, but not enough to determine reliability.
If you are concerned about lifespan look at the overall quality of the unit rather than the refrigerant gas.
Disregarding the gas option, I presume Kelvinator will be a better option in term of reliability and build yea? Never really heard of Rinnai until recently, but they're pretty cheap too. Almost like Aldi's Stirling cheap
Rinnai make great gas heaters, not sure about their air conditioners.
Kelvinator tops the Canstar Blue Reviews and Ratings so I know what my choice would be.
Yea, saw canstar review too, but then its $150 cheaper.. Dilemma
$150 is not much in the grand scheme of things when you consider a potentially better unit and aftersales service should you need it. Depends how much you trust the reviews.
Buy the one that's cheapest and with the most stars.
