Heater not warm enough

I took the heater to a dealer for repairs. They found wasp nest and******stopping up the burner. Once that was cleared (1.5 hrs labor, $157 bill; I'm in the wrong line of work), it worked fine. Was around 30F this morn and camper was comfortably warm. Thanks for all the suggestions.

The time I had low/no heat issues it was a faulty regulator. It was all gummed up from getting lp out of a tank that was just unloaded from the truck. Should have let it sit for a while. The issue described here sounds like a bad regulator or bad two way valve. Lots of times with those hand tightened fittings there is a bad connection and low/no gas. Retighten and try again. Let us know how it turns out.

According to the Texas RRC, Butane availability in Texas is no longer. They still produce it, but most LP retailers do not like the cost of having Both Butane and LP containers. Butane is for warmer climates. There may be a few old timers that still want Butane, but they are very few if they can get it. Doug

Gas pressure seems ok since the stove works just fine. Any ideas? Is there an adjustment to increase the amount of gas feeding the burner?

Just because the stove is OK does not in itself guarantee gas is getting to the furnace. Each appliance has its own copper line from the galvanized manifold located outside and under the RV. It is not uncommon to have p-traps filled with oil in these copper lines.

Natural gas is not pure metane and what is called LPG is not pure propane but a mixture of different gases with propane and butane predominant gases. The ratio of propane and butane in LPG varies with season and location same as vapor pressure of gasoline varies with season and location. The ratio of propane and butane in LPG is only known to a supplier and even the people who dispense the LPG don't know it. This may explain why my furnace worked better on Canadian propane(LPG) posssibly because it has higher content of propane and lower content of butane.

LPG gas

You still did not answer my question---HOW can(did) you determine your furnace ran better off certain LP supply. Natural Gas is just that. LP and Butane are manufactured as a by product of oil refining. I am licensed by the Texas Railroad Commission which regulates ALL LP/Natural gas operations in Texas and my last update class, they stated that Texas does not refine Butane anymore for USA consumption.

When I carried propane (the mix you defined), the shipment was loaded--propane on the first 90-95% of cargo and a cap of the last 5-10% of Butane. This was because Butane was at a much lower temp and would tend to keep the total product at a lower temp. The lab folks took care of the calculations. The propane was loaded at Hess Oil in Houston, TX and was carried to as far as Ecuador but mostly in the Caribbean. Canadian Propane may have a lower % of Butane, all of ours South of the 49th is blended to a certifiable BTU content (but, of course, it's not all the same, practically).

For comparison, I was heating up my RV the other day, getting ready to head south for a couple months. It was -5F, and 20-30 mph winds, two slides, 40'. I set it on 62F, and the furnace would shut off about 25% of the time, as it was up to temp. So, you should be able to stay warm. Be sure to check your duct work, many times it is poorly wrapped, and leaks to the underbelly.
