Best Propane Heaters For Tiny Houses

Unlike most traditional homes that are dependent on the central heating system, tiny houses have several options that are inexpensive, energy-efficient, and put out a lot of heat.

Propane heaters for tiny houses are one of the options you can try. What you love about propane heaters is that they’re energy-efficient, relatively cheap, and readily available.

When choosing the best heater for tiny house, you have to consider the room’s size and the amount of heat the unit produces. You also want to go for vented propane heaters for indoor use because they are safe. If you choose vent free heaters, make sure your tiny home is well ventilated.

Here are both vented and unvented propane heaters for tiny houses that will keep your warm and offer a powerful heating experience.

How Do Indoor Safe Propane Heaters Work?

Like any other type of propane heater, indoor safe propane heaters produce heat energy through the combustion of propane gas. The combustion process produces carbon monoxide, carbon dioxide, and many other byproducts.

Carbon monoxide is highly toxic but colorless and odorless gas. When it accumulates in a closed room, it can easily lead to fatalities.

Indoor safe propane heaters have a unique mechanism to prevent the excessive production of carbon monoxide gas.

Propane heaters used outdoors do not need this mechanism because there is enough oxygen out to ensure that carbon monoxide is turned into the less poisonous carbon dioxide.

Indoor safe propane heaters have an oxygen depletion sensor. The device can detect when carbon monoxide levels rise rapidly. A sudden rise in the amount of carbon monoxide means that the room’s oxygen is getting depleted.

When this change happens, the sensor automatically triggers the heater to shut off. This process prevents the occurrence of carbon monoxide poisoning even when you use a propane heater indoors.

Direct Vent VS. Vent Free Propane Heaters

Direct vent propane heaters comprise a glass-sealed front and a complex venting mechanism in the background. The heaters draw in oxygen for combustion from the outside environment.

When the combustion process is complete, the byproducts are similarly channeled out through the vent. The heaters are about 85% efficient.

Installing direct vent propane heaters requires careful consideration of the venting. Typically, the venting is done across walls. In some instances, the venting may be done through the roof of the house.

Ventless propane heaters do not have any venting mechanism. Unlike the direct vent propane heaters, ventless propane heaters draw oxygen from the inside of the house in which they are installed.

Also, the byproducts of the combustion process in vent-free propane heaters are released into the house’s atmosphere.

Ventless heaters are almost 100% efficient. Their installation is easy and straightforward because you do not have to worry about venting. Moreover, the installation of such heaters follows stringent standard codes to ensure that they are completely safe for indoor use.

How Much Propane Does a Tiny House Use?

A tiny house may need anywhere between 120 to 150 gallons of propane per year. Propane is usually sold in small 10-gallon tanks. The tanks can perfectly fit in any tiny house, ideally in the basement or in a specially-constructed cabinet.

For a typical tiny house, 10 gallons of propane is needed to provide warmth for a month. This consumption rate means that you will need to refill your 10-gallon tank at the end of every month.

If your rate of consumption of propane gas for heating and other functions is slightly high, then you may end up burning about 15 gallons by the end of every year. If the consumption rate remains at one 10-gallon tank per month, you will have consumed 120 gallons at the end of the year.

How Can I Make My Propane Last Longer?

The efficient use of propane gas will help you keep the heating costs within manageable levels. Here are a few tips that you can use to make your propane last long and minimize the costs of replacing it frequently.

  • Switch off the heater when you are not at home. Leaving your propane heaters on when you are not at home is a big waste of fuel and not necessarily a safety hazard. Ensure that the heaters are off when you step out of the house, even for just a few hours. This practice will minimize the amount of propane that is burned when no one is at home.
  • Ensure the intake and output vents and the air filter are clean. Having clean ducts and the air filter will reduce the amount of propane that is wasted due to inefficiency. Propane heaters with vents and air filters that are clogged produce a distinctive hissing sound. The sound indicates that a small percentage of the propane is not burned correctly.
  • Use automatic ignition. Unlike manual ignition systems, automatic ignition ensures that no small amount of propane gas goes to waste when you put on the heater.
  • Go for energy-efficient heaters. Brands of heaters have different efficiency levels. Go for energy-efficient propane heaters that score high on efficiency to ensure that you minimize the wastage of propane gas in heating the home.

Propane VS. Electric Heater for Tiny House

We can compare propane and electricity as heating alternatives for tiny houses in terms of thermal efficiency, cost, and convenience.

Thermal efficiency refers to how sufficient fuel produces heat energy. Propane is more thermally efficient than electricity because you only need to burn a small amount to produce massive heat energy levels.

Thus, propane produces more heat energy than electricity. However, it is difficult to measure the two’s performance because propane is sold in volumes while electricity is sold in currents and billed in terms of kilowatts per hour.

In terms of cost, electricity is more expensive than propane. You will have to pay for all the kilowatts that you consume every month.

The price of a kilowatt per hour is predetermined. However, buying a 10-gallon tank of propane and refilling it is affordable and much less than that of paying for electricity.

Propane is more convenient than electricity as a source heating for a small house. You can purchase, store, and use your propane gas at your convenience.

However, if you are using electricity, then you are the mercy of the utility companies. Outages in power supply will interrupt your domestic schedule and force you to use an alternative fuel source.

Propane VS. Kerosene Heater

We can compare propane to kerosene heaters in terms of propane and kerosene’s thermal efficiency, cost, safety, and convenience.

Burning one gallon of propane produces about 91,600 BTUs of energy, while a gallon of kerosene yields about 135,000 BTUs. The results show that kerosene is more thermally efficient than propane.

In terms of convenience, both propane and kerosene can be bought and stored at home. However, kerosene is known to produce potent fumes when it gets burned.

Kerosene burning heaters produce the fumes when they get lit because the air ratio to kerosene is still not correct. When the flame of kerosene heaters is lowered, kerosene fumes escape to the external environment and cause a bad smell.

Comparing kerosene with propane heaters in terms of the cost of the fuel yields exciting results. Contrary to popular belief, kerosene is more expensive than propane. This price difference means that you will spend more on keeping a kerosene burning heater than when you have a propane burning one.

Are Propane Heaters Safe for Home Use?

Vented propane heaters for cabins are safe for home use as long as you observe standard safety precautions. Primarily, choose propane heaters that have an oxygen depletion sensor installed.

The oxygen depletion sensor helps prevent the accumulation of carbon monoxide within the house when all the doors and windows are closed.

When the amount of oxygen drastically reduces, the sensor automatically triggers the heater to shut off. This helps to ensure that you remain safe even when using a propane heater indoors.

The automatic shut off prevents the possibility of carbon dioxide poisoning from occurring when you use the heater in a tiny house.

It is safe to use either the direct vent or vent-free propane heaters at home. Direct vent heaters have special pipes used to either draw in oxygen from outside or channel out the byproducts of the combustion process.

Vent-free propane burning heaters have unique mechanisms for minimizing the amount of byproducts produced during the combustion process. Additionally, their installation follows very strict safety standards and procedures.

Observance of the established safety rules ensures that it is completely safe to use vent-free propane heaters at home. Either way, you can safely use any propane heater at home.
