How to Use Vent-Free Propane Heaters Safely?

Propane heaters are absolutely safe, but only when you use them properly. Here are some safety tips, which you must follow to gain absolute safety from your unit.

  • Go through the instructions from the manufacturer properly before using the unit.
  • Having a heater built-in with a thermostat and other features like blower fan, oxygen depletion, automatic shut off, and overheat protection lets you modulate the temperature of the device as per your choice.
  • It is vital to have a proper inflow of fresh air in the space to heat up. If there is not such a system available, open your windows to permit outdoor ventilation.
  • Avoid placing any object on top of the heater.
  • Most importantly, never use the heater unattended. It is best to avoid using the heater when you sleep. For this, you can pick heaters with automatic on an off timer.
  • Keep your heating unit away from pets and children.
  • Install a sensitive detector in your home for determining carbon monoxide presence.
  • Make sure you don’t touch the heater’s body as it can lead to burning.
  • Get your heater inspected and serviced every year.
  • There must be no pathways along with your wall heater.
  • Don’t spray deodorants, air fresheners, and other sprays near the heater.

Benefits of Using Ventless Gas Heaters With Thermostat and Blower

  • Cost-Effective – One of the biggest benefits of these heaters is that they are very economical. They consume very less fuel and render great output, which makes them extremely cost-effective.
  • Brilliant Heat Distribution – A vent-free heater evenly distributes heater throughout your space. Their robust convection process offers more effective results in a very short time span.
  • Convenient Installation – The process for installation for vent free heaters is simple. Most of the models come with a simple setup and can be installed easily.
  • User-Friendly – It is absolutely convenient to use these units. They come with a simple push-button mechanism.
  • Easy Maintenance – No hefty or regular maintenance is required for these units. A simple wiping and regular cleaning of the blower lets you gain optimal performance.

How Vent-Free Propane Heaters Work?

The functioning of vent-free heaters is quite different from the vented heaters. It is because the vented units release harmful gases out through chimneys or vent pipes passing through the wall. Since they do not have a vented system, so they attempt to offer maximum combustion.

As a result, they release a few by-products, which are carbon dioxide and water. Hence, these units turn out to be a safe solution for heating homes.

Moreover, vent-free heaters with a thermostat and blower are efficient as they can easily convert propane into a heater while evenly distributing heat throughout the space.

But one important thing that you must keep note of is that vent-free heaters do emit a minimal amount of harmful gases like sulfur dioxide and nitrogen dioxide into your living space. We, therefore, suggest avoiding using these heaters while sleeping.

Furthermore, the output efficiency of vent-free heaters depends a lot on the air inside your space to fuel the combustion process. It means these units consume a lot of oxygen present in your room for combustion. This process goes on and on.

Buying Guide to Choose the Best Vent-Free Propane Heater [Thermostat + Blower]

A perfect heater is one that precisely meets all your requirements. For this, you must consider some important factors to ensure your selection is an apt fit.

1. Safety Features

Propane heaters can be highly inflammable if you do not properly consider the safety features. You must check the CSA safety certification to determine the safety parameter of the heater

It is essential to buy cool-to-touch models if you have pets or children at home as it reduces the probability of burns. There are propane wall heaters with thermostats and blowers are available, designed with ceramic cases, which cool the heater’s exterior without radiating heat outwards.

To gain protection against harmful emissions, pick heaters with oxygen depletion sensors and other additional safety features like tip-over protection or an automatic shut-off system.

2. Energy Efficiency

It is always best to pick energy-efficient models as they are certified for maximum performance with clean fuel burning. This prevents excess gas consumption and saves you on your monthly fuel bills.

Some models are dual-purpose and if you are picking heaters with a blower you must pick the most energy-efficient unit in order to avoid incurring additional running costs.

3. Heater’s Size

The size of a heater is calculated in BTU or British Thermal Units. The BTU amount required depends on room size and insulation quality in the room as well as the location. A 40 BTU level per square foot is an adequate pick.

4. Location

The place where you will locate your vent-free heater is extremely important. It is because the location must not inherit any safety risks. There must be a proper ventilation system and an inflow of fresh air in the space.

5. Ignition Process

A propane vent-free heater ignites either automatically or manually. Conventional heaters use the manual approach where a matchbox is required for fuel ignition. Modern heaters turn on automatically with just the push of a button. Mostly, people prefer using electronic ignition as the automatic ignition turns off with time.

6. ODS or Oxygen Depletion Sensor

An important safety feature to consider is the ODS or oxygen depletion sensor that monitors levels of oxygen in your house. This feature leads to an indicating alarm if there is a dangerously low level of oxygen in your space. Vent-free heaters consume oxygen from your space. In this case, ODS is highly useful.

7. Cost

Though propane heaters are cheaper than electric heaters, there is a wide range available within different price brackets. Make sure you buy a product offering a perfect blend of affordability and high performance.
