Rinnai 1004 f versus my radiators


I have a room that is 20 x 50 with 9.5 foot ceilings, well insulated and most drafts sealed. I have a Rinnai 1004 f in the room and it can heat it up quickly (but creates a lot of propane odor for some reason (thoughts?)). The conventional heating system is part radiators, part radiant with 170 degree water circulating from a highly efficient propane boiler. My question is which will heat the room more efficiently.

Rinnai 1004 f versus my radiators


Hi..

I didn't see any responses to your question so I thought that I'd give it a try..

Not sure of the question though.. A lot depends on which system may be more compatable with the room.. 170degF for a radiant system is way to high.. The systems I design .... well it was -15 last night and my system ran on 100degF. 170deF for radiators (or do you mean baseboards) is about right.. Mostly they are designed around 180degF. It seems as if you have 2 systems but both are only partial.. Maybe give me more info..

Thanks

The radiant is really just two loops and the installer said that they would really just be for comfort--they are in the bathroom and the kitchen. And you are right, I think the temp is too high because the wooden floors are suffering.

Hey..

You have wood floors? Your floor temps should never get above 80degF...So if you don't have a inferred thermometer put a regular thermometer under a throw rug.

Hi,
The Rinnai should be able to more completely heat the area as it will modulate to maintain the set temperature within the area . This will allow a more efficient heating source . The Rinnai will also "anticipate " the room heat load/loss and attempt to "fill " the room with constant heat . This will not "stratosphere " the room's temperature as a normal heat source will .
By modulating you incoming gas supply , the Rinnai unit should be most efficient .
Good Luck !

Another note regarding the smell of propane . Please makes sure you shut the gas supply off ! And contact the appropriate personel to find out why you have a smell!
The Rinnai is a Direct Vent product . This means you have a "Pipe within a pipe " vent system .
It bring combustion air from outside and expels the exhaust to the outside through the same piping system . There should be absolutley NO ODOR from the gas supply in the home !
Please consult your Rinnai installation operation manual for Cautions regarding any gas smell .
If the unit was converted form NG to Propane , there are several ares to investigate for leaks . The incomng gas fitting has an O ring that could have fallen out of place when the conversion was done . Also the incoming gas fitting may have been cracked if not backed up by a second wrench when initially installing the gas supply hose .
Please have a qualified service technician investigate these issues .
This is a gas fired appliance and is subject to HUGE liabilities for you and your family !
Have the service technician call Rinnai Tech Support for assistance if needed.
Good Luck !

Thanks for both replies. The gas smell was worse until I had a separate technician come and he found a large kink in the supply line behind the unit. It is much less now, but there is still some propane odor. I'm not sure what normal may be here...

Caution !!!
You should not have ANY smell from the incoming gas supply ! I would investigate the supply hose that was kinked . Was it replaced or just straightened?
If all incoming gas supply fittings are correctly tightened (Not torqued beyond sealing /and this can happen !)and have the proper sealant applied (if needed) there should be no smell !
I go back to my earlier post where I cautioned against using the product when you still have a gas smell ! Gas can "pool" in areas and cause an explosion as a result !
Not trying to scare anyone but this is a gas fired appliance and there is a big safety/liability factor involved here ....
Be Careful and good luck !

Once kinked needs to be replaced.
