A propane heater consumes 2.6 gallons to 40 gallons of propane a day, provided it is used continuously (most will not).
A 30000 BTU heater consumes 7.9 gallons of propane a day and an 80000 BTU furnace consumes up to 21 gallons a day.
Propane furnaces and heaters come in a great number of types and sizes. They may be applied in tents, cabins, garages, patios, basements and even in the house itself.
This article will provide you with the information you require concerning the amount of propane you are likely to consume in case you possess any of these heating appliances.
How Much Propane Does a 30000 BTU Heater Use
.33 gallons or one third gallon per hour. It would consume as much as 7.9 gallons in a day.
How is this determined?
The open (non-ducted) propane heater has heat that is directly produced by the open flame. In practice therefore, they are 100 percent efficient, that is, all the heat energy will be present in the room that is being heated.
A gallon of propane will give approximately 91,500 BTU per hour (91,500 BTU/h).
Therefore, when we divide 30,000 BTU by 91,500 BTU, we will obtain 3.05. This is the number of hours that one gallon of propane will go when used by a 30,000 BTU heater.
This implies that the same heater will consume about 1/3 of a gallon of propane in a span of 1 hour.

How Much Propane Does an 80,000 BTU Furnace use?
It will consume .9 gallons an hour or approximately 21 gallons in every 24 hours of operation.
Ducted furnaces which do not blow hot air out of the furnace into the space they are heating are not as efficient due to the manner in which they generate heat in a building.
As an example, a forced air propane furnace burns the fuel in the furnace that heats a heat exchanger and the gasses are released through a vent or chimney.
The rooms air is forced over the heat exchanger and is heated indirectly by the flames and not directly as in a heater. This gives an output of 80 to 99 percent of the input value of 80,000 BTU.
Therefore, an 80,000 BTU furnace will consume about .9 gallons per hour, or nearly 21 gallons per day assuming that it ran 24 hours a day, but in a well insulated house and assuming that it is sized correctly, it will not run 24 hours a day.
And the more efficient the furnace the more BTUs it will provide into your living space.
- 80,000 x 80% = 64,000 BTU of heat to your living space.
- 80,000 x 90% = 72,000 BTU.
- 80,000 x 95% = 76,000 BTU.

How much propane does a 10000 BTU heater use?

Are Ventless Propane Heaters Safe?
The question that many people ask is whether they are safe, because there is no external outlet to the combustion gasses.
When a propane appliance is operating correctly, it will give what is known as an ideal burn during the heating process and will pose no threat of carbon monoxide poisoning.
Also, every indoor propane heater except the very cheapest will have a safety device known as an oxygen depletion sensor, which will shut the unit down automatically in the event that the oxygen level falls below a specified level.
How Long Will a 20 Pound Tank Last?
A 20 pound tank or bottle has approximately 4.7 gallons of propane. It will operate an 18,000 BTU heater such as the Big Buddy by Mr. Heater, 24 hours at full blast or approximately twice that on the 9,000 BTU setting.
A 20 pound tank will power one of the more popular 30,000 BTU ventless heaters approximately 14 hours.
What is the Advantage of a 2 Stage Furnace or Heater?
They come in two levels of heat. The low heating is either 65 or 70 percent of full capacity depending on the brand/model.
One hundred percent is high heat.
A 2 stage furnace will save you energy cost since it will operate at the lower capacity whenever it is able to generate enough heat at the low capacity to meet the requirements of the thermostat.
When the weather is very cold, it will be forced to work at 100 percent more of the time in order to warm your home.
