What is the Best Ventless Gas Heater with Thermostat  and Blower

However, if you get indecisive, we recommend going with our top choice; the Mr.Heater Corporation F299730. It offers everything you would reasonably want in a gas heater with thermostat and blower, all while remaining relatively affordable. 

Many homeowners place safety as their top priority when buying gas heaters. If you are willing to spend more for all the safe-use features you can get, go with the class-leading Rinnai FC824P. You will not have any worry about leaving the heater unattended with your children or pets in the house. 

As you have likely uncovered, the high-performing, feature-packed gas heaters are the priciest in the market. If you are cash-strapped, however, you can go for the 10,000BTU Procom MG30TBF. With its under $200 price tag, it proves that you do not need to sell a limb to get reliable heating. 

Frequently Asked Questions.

Now that you have decided to buy a ventless gas heater with a thermostat and blower, you need to know how it works. If you have any questions regarding purchasing and using these heaters, then keep reading. You will probably find the answer below. 

Q: Are ventless gas heaters dangerous?

A: The concept of ventless gas heaters is straightforward. Burning propane gas creates “smokeless” heat that does not require a smoke extractor.

However, some of these gas heaters are not as safe as you may think. As a carbon compound, propane consumes oxygen and gives off carbon oxides when it burns. Over time, these heaters can dramatically reduce the oxygen levels in a poorly-ventilated room. Worse still, burning propane in a poorly ventilated space can release carbon monoxide.

Gas heater manufacturers know that keeping your windows open to maintain ventilation can undermine your heater’s efficiency. Therefore, most top heaters come with an oxygen depletion sensor and a carbon monoxide sensor. These instruments monitor the air quality in a room and shut off the heater if dangerous conditions are detected. 

Some heaters also include advanced safety features for more convenient use, and to minimize the risk of fire. These functions include:

  1. Tip-over protection: automatically shuts off the heater’s power if it is accidentally knocked down or tipped over. 
  2. Overheat protection: turns off the heater when the internal components reach an unsafe temperature.
  3. Cool-to-the touch: prevents burns caused by accidentally touching the heater. The casing remains cool even when the heater radiates heat.

As you would expect, additional features add to the price of a ventless gas heater. If you are on a budget, you must determine the functions that are most important to you. 

Q: How do ventless gas heaters work?

A: Ventless gas heaters are room-heating devices that have no chimney vent. Therefore, they do not vent air to the outside of your home. Instead, oxygen is taken from the room where the unit is placed. The resulting heat is then vented out directly from the device. 

Convenience is a significant advantage of vent-free gas heaters. On the other hand, the degradation of indoor air quality is a notable concern because of the reduction of oxygen levels and carbon monoxide emission. Fortunately, many devices in today’s market offer air monitoring sensors and burn fuel with nearly 100 percent efficiency.

Q: What is the right heating capacity for a ventless gas heater?

A: When shopping for a space heater, one of the most important things to look out for is heating capacity. Propane heater capacity is measured in British Thermal Units (BTU). The size of your space determines the BTUs you need. 

Experts recommend 40 BTU per square foot of space. So, for a medium-sized area of 450sq ft, you would need 18000 BTU. However, this guideline is a general rule of thumb. It does not apply to every model. Other heaters may cover more or less space, depending on their heating technology or your indoor environment.

Q: Are ventless gas heaters noisy?

A: Like many housing appliances, ventless gas heaters emit some noise when running. However, some models produce more sound than others. For instance, convection heaters are generally quieter than heaters with blower fans. 

To determine your noise tolerance, consider where you intend to use the heater. A low-noise heating unit would be a perfect fit for your bedroom or office.

In case you hear any loud popping sounds from your heater, make sure to have it checked by a professional.

Q: Can you vent a ventless gas heater?

A: Unfortunately, you can not convert a ventless gas heater into a vented one. These devices are designed in a way that a vent cannot be added to them. If you want a vented gas heater, your only option is to replace your ventless system with a new vented unit. 

Wrapping Up

Ventless gas heaters with thermostat and blower are great alternative heating solutions for indoor spaces. They provide smoke-free warmth efficiently, and they are easy to use. Technological advancements have also made them safer over the years. Best of all, they are more affordable than central heating systems.

We do not doubt that this post will guide you towards finding the right ventless gas heater for your space. Go out there and do some shopping!
