Best Natural Gas Heaters of 2025

"I've tried multiple brands over the years, and I can confidently say this one is the best. Its simple design works well, and I even bought another for a different room. I only wish I'd chosen this brand sooner. Installing the fan kit was also a breeze. Plus, the AAA battery for the push starter means there's no loud click or bang noise like the others. While I’m not thrilled about replacing the battery, it’s definitely better than the noisy alternatives."

"This heater has been fantastic for the past two years. Installation was a cinch, and it costs significantly less than running central heating. It easily heats our 1300 sqft home, and I've never needed to set the thermostat above 2.5, even during the coldest days here in southeast Texas. It's truly a great investment that pays for itself!"

"I bought this heater for an insulated garage room after a wall furnace failed. I had been struggling with expensive electric heaters, so finding this was a lifesaver. The gas odor is noticeable when entering the room, which I hadn't anticipated, but I'm managing it with an air purifier. The comfort level is impressive, maintaining a steady temperature of 70 to 73 °F. I appreciate having the option of a white color too! Despite a couple of minor issues, I highly recommend it—it's a great buy!"

"I installed this heater on my 2nd floor landing to supplement the heat. It puts out great heat and looks nice. However, I have one complaint: the fan sits WAY TOO CLOSE TO THE WALL, which I worry may shorten its lifespan."

"This is my third Mr Heater. I replaced the old one after 14 years. I just prefer having a new one, and I have always found them to be quality products."

"I bought this product in January 2024 to replace one that was about 8 years old. What a disappointment! The one I received didn't have a glass piece in front of the flames, and the electric starter was faulty. I contacted Mr Heater, but the glass protective piece is no longer included. I feel unsafe using it without that feature."

"This product has been a lifesaver for me this winter. My baseboard heaters froze while I was out of town, and I had to wait for repairs. I've been using this as my only heat source downstairs, and it keeps the temperature at a comfortable 67-70 degrees on full blast, which is perfect for the three rooms I need to warm. Great value for the money!"

"I had to take this heater apart and adjust the thermocouple because it was incorrectly positioned from the factory. Once I did that, it worked well and produces a lot of heat. I definitely recommend the optional fan upgrade. It effectively heats half my house during power outages, making it a solid option for both primary and backup heating."

"I purchased this heater to use as a backup for power outages, but now I find myself using it every morning to chase away the chill in my home. It heats my 800 sq ft space in about 30 minutes, and it's more cost-effective than my furnace. The installation was straightforward, and I highly recommend this product!"

"I already had the larger model with temperature control, but when I needed another, this was the best option. With only two heat settings, it heats up my well-insulated 10x25 space quickly. I often have to turn it down from high to low because it warms up too fast!"

"We got this gas stove for extra heat and as a backup during power outages. It has a fantastic heat output, looks great, and is energy efficient. I've had this brand before and it lasted over a decade!"

"This heater is perfect for my cold laundry area. I usually keep it on low and turn it off at night, cranking it up to high in the morning. For the price and simplicity, it's unbeatable!"

"I really like this product, but the #1 setting doesn't work; I have to switch to #2 to turn it on. The fan is quite loud, but overall, it's very efficient with minimal fumes. It's definitely better than my last one."

"The blower on this unit is great; it really helps with circulating and distributing the heat throughout my space."

"I installed this heater as an additional source for my 795 Sq Ft home, and I'm really pleased with the design and output. I just wish they offered larger models, as I'd consider using it as my primary heat source."

"I found the installation process to be incredibly simple, even with my limited plumbing skills. After setting it up, I'm very happy and impressed with its performance. It cycles on and off effectively, just like a regular heating system."

"I needed a heater for my garage and this product seemed perfect. However, I didn't realize I would need a professional to hook it up. It can't be returned, which feels like a pretty good deal for the company, but I wouldn't give it a one-star rating."

"The assembly was straightforward, and it works exactly as I expected. I would have appreciated a bit more instruction on connecting the propane tank, but overall I'm extremely pleased."

"I appreciated that it works well out of the box and the fan makes it even better! The price is reasonable for what it does."

"This heater is simply wonderful. I placed it in my bedroom, and it keeps the space toasty warm on the low setting."

"I installed this heater as a supplement to my central heating. It's fairly simple if you know how to install gas pipes. I found the instructions unclear for turning the control knob, but overall, it works well when I'm in the room."

"It's worth every penny! This heater kicks out heat and warms the basement in no time."

"I liked it so much that I bought another one. Great price and product!"

"This heater works very well, but I've had some trouble keeping the pilot lit. It's frustrating, and I think I'll look for a different heater."

“Installing this unit was a breeze, and it really warms my room effectively. At night, I adjust it so my furnace takes over while I sleep.”

“After our old gas heater from 1992 finally stopped working, I discovered this Mr. Heater model on Amazon. I’m extremely pleased and look forward to enjoying many cozy hours in our sunroom during winter at the Jersey Shore.”

“I encountered a problem with the product kit. It was advertised as a Natural Gas heater but came with Propane (LP) lines. This could have caused a serious issue if installed as is. When I reached out to customer service to return it, I was told I’d need to cover return shipping and had only four days to send it back. Now, I’m stuck with a product that’s unusable.”
