Is a propane heater affordable to maintain?

A possible concern for anyone looking to invest in a propane heater will be whether they can actually afford to maintain it once they have it.

The answer is that a propane space heater can be affordable to maintain, as it does not run on electricity, but on liquid propane for fuel.

This means you can stress less about any increases to your electricity bills. Propane heaters are also generally cheap to buy and operate, as you will only need to have fuel ready, which you can buy to last.

Types of propane space heaters

There are two types of propane heaters. Some are vented, which makes them safe to use for warming your indoor spaces. There are also unvented heaters, which are better used outdoors.

It is strongly advised that you never use the unvented propane heaters indoors, as they can pose serious health risks.

Unvented propane heaters reduce the levels of oxygen in the room and emit harmful carbon dioxide and other gases in closed-off, indoor spaces. This can be dangerous for people in the room, as inhaling these gases also pose a big danger.

What to look for in an indoor propane heater

If you are purchasing a propane heater for indoor use, there are important aspects to look for to ensure it is good for your space and safe to use.

You should choose a propane heater that will be the right size for your room and that possibly carries the Underwriter’s Laboratory (UL) label.

You should also look for features in the unit such as a low oxygen sensor, high temperature coated safety guard, overheat protection, as well as the automatic shut-off feature if the heater falls over.

Final thoughts

The cold winter season calls for one to keep as warm as possible and that often means investing in good quality heating appliances for your home and space. Space heaters are the go-to option for keeping your spaces warm, both indoors and outdoors.

When looking for the right space heater to cater to your needs, how much heat a space heater produces is something you want to look for. Propane heaters are known to produce the most heat and can be used efficiently with indoor-safe and outdoor-safe propane units available.
