Heating Your Tiny House with Gas Heaters

What Makes Gas Heaters the Best Pick?

There are many options to choose from when it comes to portable heaters for a tiny house. You can pick between wood-burning, gas, or electric heaters. But which of these three options is the best one?

Many homeowners like the idea of getting cozy near a wood-burning heater, but they tend to forget the work it takes for a wood stove to start producing heat. Wood stoves are also generally bulky – even if the small ones might still take up too much floor space in the tiny house.

For people who don’t like getting their hands dirty by preparing a wood stove, an electric heater may sound like a viable option because it only needs to be plugged into a power source. However, the biggest challenge when it comes to electric heaters is that they don’t produce enough heat and they are expensive to run. They are not exactly a practical pick for tiny home dwellers living off-grid.

On the other hand, a gas heater provides a reliable source of heat. This cost-effective type of heater is also environment-friendly and has a higher efficiency rating than electric stoves. Gas heaters also come in portable options, which make them the best choice for tiny house owners looking for a reliable heating system.

Types of Gas Heaters

Here are are three main types of gas heaters and how they work in warming the tiny house:

  • Catalytic Gas Heater – This type of gas heater is flameless and relies on chemical reactions to produce heat. A catalyst combines oxygen and natural gas to ignite at low temperatures without the need for a flame. This gas heater makes temperature control easier because owners manipulate the amount of natural gas that reacts with the oxygen.
  • Forced Air Heater – This kind of gas heater distributes heat around the house through forced air. When the mixture of natural gas and oxygen ignites and produces heat, the forced air distributes the heat around the house.
  • Radiant Heat – This type of gas heater utilizes electromagnetic radiation to ensure that heat is evenly distributed around the house. Instead of a flame, it has tubes, filaments, or ceramic heat exchangers to distribute the heat created by the gas and oxygen’s reaction.

What to Look for in a Gas Heater

Here are a few features to consider when looking for a gas heater for a tiny house:

  • Portability – When heating a tiny house, you’d want to get a portable heater that won’t take up much space. The heater should be moveable from one area of the house to another – wherever the heat is needed. This allows you to heat different rooms without wasting energy.
  • Safety Feature – Natural gas is harmful when mixed with oxygen, which is why it’s crucial to buy a heater that keeps the gas and oxygen levels in check. The heater must have an automatic shut-off system that gets triggered in case of a leakage or low oxygen levels in a room.
  • Heat Output – Another important aspect of a gas heater is its heat output or capacity. It tells how much heat is produced by a gas heater. Gas heaters with high heat output tend to be more expensive but getting a heater with low heat output might be insufficient for heating the entire house.
  • Cylinder Capacity – Gas heaters come with cylinders to hold the natural gas it burns. These cylinders must be refilled every now and then, which is why it’s better to buy a gas heater with a sufficient cylinder capacity. This allows you to make fewer trips to the store just to buy natural gas for the heater during cold days.

Keep Your Tiny House Warm and Cozy with Gas Heaters

A gas heater is a must-have for any tiny house, especially for those living off-grid. Aside from keeping the tiny house warm and cozy during the cold months, it also helps owners save more money by cutting down the electricity bills by a significant amount. Make sure that you’re well-informed about gas heaters first to create better buying decisions for the tiny house.
