Moe said:mkmh, I noticed you have a few Rinnais. Do you like them? I'm considering switching to natural gas rather than replace an old oil boiler and a very old oil tank in a five-room office, and someone suggested the 1004 Rinnai and a Rinnai tankless water heater. Any thoughts?

The Rinnais are phenomenal if you are ok with heating with LP or Natural Gas. My 556 is over 10 years old and it has literally never had a problem. The smaller unit is about 2 years old, zero issues. They just plain work, and throw great heat while maintaining a stable temp. They are also extremely efficient. the problem is that LP in my area (and I suspect most areas) is crazy expensive, and the pricing is nearly as erratic as oil.
Consequently, I don't use the 556 as much anymore, and i'm considering selling both units in the next few years and adding some baseboard eletric heaters.
I've heard the Rinnai tankless water heaters can be great if you get an installer that knows what they are doing. They can cause major headaches if installed wrong.
If you search the web for reviews on themm you'll find some dissatisfied customers for sure.
Personally, I'm fed up with oil and propane, so my 3 year plan is to convert to 100% electric and pellets.
Here is a dealer in Brunswick that has a pretty interesting web site. You can tell that the guy is passionate about heating!
