I moved to the new unit and the Rinnai Energysaver 556 FTR was here awaiting for me!!!
I am happy with it but because I am vision impaired I cannot see it it works with gas or electricity. It is gas is it not? Sorry I ask an obvious question... I do not know when it was purchased... so I'll click on anything so I can send you my query.

Have one of these to heat my shop. A few years ago the heat exchanger wall burned through just after warranty expired. Parts were not available to fix it, so it was repaired with furnace cement. Now I find out the RHFE-556WTA was recalled for the seal that leaked and caused the exhanger to burn through and now I'm told parts that have burned aren't covered. What gives? Not buying another one of these ever again. I'm lucky my shop didn't burn to the ground! Guess I'm getting out my scrap sheet metal to fix this again before I freeze.

This heater has been the best thing since sliced bread for our family. Our model is actually Ebergysaver 557 FTR, a smaller version of the 556 FTR. We have had it for about 5 yrs now.
Instant heat, we have a small house and it heats most of the house, easy to regulate temperature, water basin to prevent air drying out, has lots of features but we don;t tend to use them, gas is cheap.
So far nothing.

going to pursue full repair from rinnaii, i have recommended and installed these heaters to a lot of people, now i have ended up with the crappy one,,
557 FTR,, mine fitted in a tight area that i had, i have installed many of these heaters, never heard a complaint until now
ours has ran great for 18 months, now vibrating badly and chirping like a angry canary, find the warranty is 2 years on fan but 1 year only on the labor, how does that work ?,no new fans available for a month also

The conversion from our old electric fan heater to this was the best investment we ever made. It doesn't seem to kick up the dust like our old one so good for asthma sufferers and it's very child friendly.
Energy efficient and doesn't cost much to run. It heats up quickly but doesn't get so hot that children can burn themselves. Thermostat works well. Child lock prevents curious fingers from changing settings. Timer is also handy. Fan doesn't seem to kick up much dust.

A heater that performs to expectations and has handy timer options including timed turn on to preheat before you get home although I haven't that option yet, it heats the room pretty quickly anyway. It is fairly economical, quiet and isn't too ugly as it blends into plain decor. I have no reserves about recommending this heater to others and have already convinced a family friend who bought 2 and is also happy.
Looks good and is economical heating option. Heats the area that is suggested for the output no worries and the thermostat keeps the room at that temperature. It is so quite that you can forget to turn it off.
