Assuming you cleaned the rear filter… All it can be is starvation of the fan, but unfortunately these heaters are as [Content Removed] ! Not much better than a candle

Lmfao. You must be from Melbourne? Northern suburbs or there abouts. As [Content Removed] is as common a saying in these parts as '[Content Removed].' But yes you are correct and burning candles would probably work out cheaper.

We replaced an old Rennai heater we bought 40 years ago with the 559FT. The old heater, which did not have a fan by the way, performed far better than the new one. Compared to the old heater, the new 559FT is useless because it fails to heat rooms satisfactorily. The area it has to heat with us is 63m2 in Auckland NZ. And it’s no good calling Rennai. They’ve got our money now and don’t really want to engage.

Thanks for your help

Do yourself a massive favour and take it back to the shop for a refund before you unbox or think of install it. They are simply too small and run constantly. It will only ever reach 23 degrees on a spring day.

Thanks for the input my wall furnace is 30 years old heats up my open plan rooms but dying and no way I’ll get the new ones as they are rubbish. Hard job to find a heater that will do the job

Lorraine, I agree with Jade, we have had a 559ft to supplement our central ducted system on those not so cold days when the use of a full house system is just not economical. From the beginning the 559 was not up to the job. Yes it would heat up eventually, but it could not maintain the selected temperature and was working hard all of the time. This week we had installed the bigger version, the 1005FT. What a difference!! Twice the performance and it is only ticking over we are not game to turn it up full. It rivals the central system for fast heat up and easily maintains temperatures not achievable by the 559. Thank you to the Rinnai tech person who suggested this option. we are very very happy (and warm) We are right at the highest point in the Blue Mountains.

Hi Kirstin. Unfortunately this is normal for the 559FT. It’s a lemon. We have had problems with this unit from day one. After many call outs to their technicians and various parts replaced Rinnai replaced the heater with a new one. Still issues with new one after calls to them again Rinnai would not reply. Have given up and put it down to purchasing at least one lemon in my life time.

Hi Peter,

Thank you for your question.

This would be fine to be turned off if not required.

Thanks Rinnai Australia

It's a long shot and a wild guess, but I am wondering if the air temperature and flow sensor is dirty. It happens on diesel engines in my experience, so why not your heater? Low down at floor level, there is a grille. You can press the end catches (tricky to find) and remove it. Turn the heater off and feel around inside behind the grill. You should feel a thin rigid tube protruding down, with a tiny bulb on the end a bit like a match-head. I am guessing it is a temp/flow sensor. Wet a cloth with alcohol and wipe the bulb. There is an aerosol spray can called "CRC MAF Sensor cleaner" (MAF = Mass Air Flow). I don't recommend spraying anything into the heater though. Alcohol on a cloth should work fine, maybe iso propyl alcohol. Or maybe just even Methylated spirits. Do not touch the sensor with bare fingers after cleaning it. Hope this helps, best of luck, Gary (NZ)

Hi Paul, thank you for the question. There could be a number of reasons for the heater not getting to temperature and a service call may be required to diagnose the issue. In a lot of cases it may be that the heater is not the correct size for the room installed. You have speak with our technical department on 1300 555 545 and they may be able to help you.

Hi Jan I have not found any problem with the heater drying out the air and have had my heater on all day long for the past couple of months. Also I have not used the water tray at all. Do you have the Flued model? I can only suggest that you talk to Rinnai head office in Melbourne Cheers Ron

Thanks for your answer. Yes we have the flued model. Maybe we are running it too high for our small room, what temp do you recommend?

Thanks for the question Jan, we would recommend contacting our Technical Department to discuss this matter further. They can be reached on 1300 555 545 (option 3).
