Heating with Wood vs. Propane
If you want the ambiance of a real fire without the maintenance of a wood stove, a direct vent propane fireplace might be an option for you. A propane fireplace allows viewing of the dancing flames of a real fire, while providing dry, radiant heat to your home similar to a wood stove. Unlike unvented propane appliances like catalytic heaters, a direct vent propane fireplace exhausts combustion gases outside of your space, so there’s no buildup of water or depletion of oxygen in your living area. And unlike forced air furnaces, propane fireplaces require little or no electricity to operate, and they are quiet or silent while in operation.
There aren’t many direct vent propane fireplace options available for small spaces as of this writing. The only one we typically find in small spaces is the Dickinson Marine Newport. But we are developing the Dwarf Gas Stove that we hope will be ready to ship in 2019.
Pros of Propane Heat
With propane you only burn as much fuel as necessary to maintain inside air temperature. If your heater is controlled by a thermostat, once the temperature is reached, the burner shuts off. This saves fuel and maintains a steady, constant temperature in your living space.
Propane heat is easy and convenient. The only chores that come with LP is keeping the tank full, turning on then setting the thermostat — done.
A properly calibrated propane fire burns very cleanly, so propane fireplaces are very low maintenance relative to wood stoves. After your propane stove is properly installed, all you need to worry about is keeping the propane tank full, keeping the pilot assembly clean, and sweeping soot out of the flue as needed.
Lightweight and Compact
Propane fireplaces are small and lightweight. The installation allowances and footprint is very narrow and can be installed in the smallest of spaces.
Cons of Propane Heat
Cost of Propane
Heating with propane can be a significant expense. Depending on prices propane ranges from $2.75 – $3.75 per gallon. The Dickinson Marine fireplace burns roughly 1lb of propane every 5hrs on high (7500btu). So a standard 20lb 5 gallon tank would burn for 100hrs on high and cost $15-20.
While there is an abundance of cheap propane today, that may not always be the case. What if the price of propane doubled or tripled? Or what if propane was no longer available due to a shortage or interruption in supply lines? Wood can be foraged, but propane needs to be purchased.
Volatility of Fuel
A leak or malfunction could cause an explosion. Propane is very volatile and if a leak happened in a small space it could be dangerous! On top of that, propane gas is poisonous. Most appliances have safety valves so if the flame goes out the gas is turned off, and propane detectors installed in a living space can detect leaks at very low levels. Proper installation and maintenance should be trouble free.
Burning 1 pound of propane releases approximately 1.6 pounds of water. For every 20 pound cylinder burned, nearly 4 gallons of water are produced as water vapor.
While appliances that vent outside don’t add to condensation problems, unvented propane appliances like catalytic heaters can cause mold and mildew problems. Wood heat adds no moisture to the air, and can help correct moisture problems during the winter.
Wood fuel is a renewable resource when harvested responsibly, and when burned in a quality stove, wood is a fairly efficient heat source. Wood burning stoves have been around for hundreds of years and technology, efficiency and emissions have greatly improved! While there is an abundance of traditional wood stoves on the market, if you are heating a small space there are far fewer options.
Small Wood Stoves
Recently, there have been an increasing number of suitable small wood stoves for tiny spaces. Some are made for the Marine industry for use on sail boats, cabin boats and canal boats. Other stoves, like our line of small wood stoves, are made specifically for tiny spaces like tiny houses, RVs, and bus conversions. These stoves are small, lightweight and produce enough heat as a backup heat source or a primary heat source for a small space.
Here are some pros and cons of wood as a heat source…
Pros of Wood Heat
Widely Available Fuel Source
Firewood is abundant. Take a stroll through the woods and you will see an abundance of down, dead and dry firewood. Landscaping companies often have a lucrative side-business reselling trees removed from their customers’ property as firewood. Hardware stores, farm supply stores, gas stations, and even grocery stores typically sell kiln dried firewood in bundles.
Affordable Fuel Source
Depending on your location, firewood is probably available for cheap or free. If you own or have access to wooded property, downed wood can be gathered in abundance for free. If you have somewhere to store it, firewood can be purchased in bulk for relatively low cost. Even if you need to purchase kiln dried firewood in bundles, a tiny stove uses very little fuel, so the fuel cost is often minimal.
The top of most stoves gets very hot! This is a great surface for heating some tea or cooking a meal. Some small wood stoves have an oven built in … hot chocolate chip cookies, anyone?
Who doesn’t like the dance of flames and the warm dry heat from a wood-fire? I personally love the sights and smells that come with wood heat!
Cons to Wood Heat
Climate, No Humidity
The dry heat from wood stoves saps humidity from your space. This lack of humidity can dry out skin and surrounding wood furniture causing damage. If you heat with wood, get a hygrometer and keep track of your humidity levels. If your climate gets too dry, you can add some humidity into your space by placing a kettle or a cast iron steamer on top of your stove for a while.
Weight and Space
Wood stoves can be heavy and bulky, depending on the size and model of your stove. Every wood stove will have clearance requirements for how far it has to be installed from combustibles. For the tiniest of spaces, safe installation can be a challenge.
Wood heat is a lot of work…splitting, hauling and storing wood, starting fires, stoking the stove, cleaning out the ash, cleaning out chimney build up. If all of this sounds like a headache, then wood heat might not be for you.
Ultimately, the ideal heat source comes down to long term cost and how involved you want to be in the process of heating your home. Do you want to be independent of fossil fuels and don’t mind some extra chores? Then a wood stove is right for you! Or do you favor convenience, don’t mind buying propane and just want a warm space? If this is true then a simple propane fireplace is the best option for you.
I hope this has helped you narrow down the right heat source for your tiny space!
