to fotie... I just bought the sames 30,000 btu blue flame heater you have and was going to hook mine up the same way you did off of the grill tank. my question is.. did it work and how long did it take for the tank to go empty? thanksM Foti wrote:thank you folks, good information about the on demand unit... My propane is a little more than "emergency" heat, but it is not our main heat source. During a normal winter I use the wood a solid 85% -95% of the time. During fall and spring, it isn't really worth it to start a fire that will only be used for a few hours during the night so I use the electric during these "in between" times where it only gets cold for a few hours. I just got the blue flame heater hooked up and running it off of a grill tank just as an experiment, it has a nice thermostat on it so I'm curious to see how long the 4 gallons in the grill tank lasts, that will give me a little bit of an idea... When I heated my shop with a 30k BTU radiant propane heater (the kind with the bricks w/ tiny holes) it had to run full blast to overcome the concrete slab and poorly insulated garage doors. Running full blast, it cost me about $1.50 per hour (I can't remember the cost of propane during this time).
I have no idea what will happen with the thermostat to actually regulate usage, but at least I'll have some sort of baseline to judge from. We're expecting a cold week here in western north carolina (chilly at night anyhow) so maybe that'll give me some clue...
Regarding the advice on having each unit on it's own circuit... I may go with that. The one 100lb tank for the kitchen stove lasts approximately six months and we do a fair amount of baking. I imagine due to surface area alone (for the propane to turn to a usable gas) I'll need at least two plumbed together for the heater AND for the water heater.
The reason for pre-heating the water going in to the gas water heater (from what I understand at this point but I am new to these) is that I don't have to run the water heater full blast to heat the water to a usable temperature, I can turn the main valve down a bit. Luckily (in a sense) we have not started building the house yet, so we are in a 14x56 mobile home, the longest run the water heater would have to make is 20 ft. away... This is a BIG unit, 90 degree temperature rise at 4.5 gallons per minute, got it for 10 bucks at a thrift store haha, ridiculously good deal...
