Rinnai EX38CTN Space Heater Wall Furnace, Direct Vent, Natural Gas (38.4K BTU)

I bought this to replace a 22,000 btu Rinnai wall heater. So far it has been relatively easy to install and puts out considerably more heat. Winter will tell. The vent pipe was the same as the smaller version and in the right location helping with the install. The old heater will be installed in a room where it is difficult to heat

The heater arrived on time and the package was in great shape. I did my own install and this unit works great! Very easy to install. I heat my 800 sq. ft. home in Michigan using this and it keeps it nice and warm!

This is a direct replacement for same Rinnai furnace we have had for over 20 years. Installed new furnace yesterday and found damage all over the outside sheet metal dents and dings. This is the second furnace because the first one was heavily damaged during shipping. It look like it was dragged behind the delivery truck. This second one look better until I did the installation and found a lot of damage although furnace seems to work OK. I am a little concerned it gets hot on top where the old one did not. Rinnai does not package these well for shipment. Should be in a wood crate instead of flimsy cardboard and Styrofoam. Even though there is warnings all over the box (fragile do not drop) I think that is a signal to UPS to throw it around and drop it as much as possible.

First off these units have made us Rinnai fans and we recommend the brand to anyone and everyone. We had a previous model but the fan bearings seized in up after 16 years. We have 2 issues: 1. The product was delivered damaged. i did not receive feedback from the company, at least not that i am aware of when i tried to make contact. the mounting brackets were bent pretty bad but were fixable; however, the bottom left side (when looking at it)of the unit was bashed in as well. that is not fixable without taking off every painted piece you can see to get to the units frame. Since it is on the bottom back corner of the unit it is virtually invisible the way we have it installed. Probably would have sent it back but our previous model died in early February in eastern Oregon. we were sort of over a barrel, so we kept it. 2. The other issue with the unit is that it must have different sensors than our previous model. We have a 135+ year old house the winter chill just seeps in. Our old model ran more more or less continuously, quietly humming in the background, going from low to medium. This new unit gets the house to temp fast, then turns off....then 5-10 minutes later fires up and heats the house, then turns off... We aren't sure if it is actually louder than the previous model or not, but it is definitely noticeable since it cycles from off to medium/high. After 1 month of use the gas bill seems the same as always. Lastly, and this is not a complaint, Rinnai did away with the metal hatch cover over the buttons. We prefer the look over the old cover. Downside: the cat likes them, too. He will sit on that end, which is near us, and look out the window, occasionally getting by the "child lock" and turning the unit off. So far he has only turned it off once while we were asleep.

We were looking forward to getting this heater installed but the product was damaged. It looked like someone had removed the heater from the box and maybe returned it previously but many of the pieces were dented including the front of the heater. Waiting on a replacement.
