Reznor vs. Mr. Heater: Which Heater Is Better?

Reznor vs. Mr. Heater: Which Heater Is Better?

Both the Mr. Heater and Reznor heater brands are well-known and have been in existence for a long time. It is preferable to choose a heater based on its reputation for high performance and quality. Choosing which of the two brands is best for you, though, can be difficult.

If you’re only concerned with the product’s quality, Reznor is a superior option. The company is a market leader in the heating sector and is highly regarded by both contractors and customers. But if money is tight, Mr. Heater costs half as much as Reznor.

It’s important to consider other factors while selecting the right brand for you rather than just public popularity. The easiest approach to determine which brand best meets your needs is to look at the features that each one has to offer. Continue reading as we go over all the information that will assist you in determining which brand will work best for you.

What Characteristics Do Mr. Heater And Reznor Share?

Both heater brands have been in business for many years and are recognized for producing heaters of the highest caliber. Despite this, the two brands don’t have many things in common, and each has a unique selling feature.

While consumer opinions of each brand vary, both offer top-notch customer service. On their website, Mr. Heater offers timely support to clients who require product replacements and has a dedicated page on product recalls.

What Distinguishes Mr. Heater From Reznor?

The products from Mr. Heater and Reznor differ in a number of ways. The characteristics you need to look for in a heater are listed below. Let’s talk about the qualities of both brands in each of these areas.

Reputation Of The Brand

Both Mr. Heater and Reznor are preferred by customers, but Reznor is preferred more by contractors and consumers due to the high quality of their products and the expert design of their heaters.

Customer concerns concerning control board failures, problems with the heater’s fan board, and troubles with the ignitor are frequently seen in evaluations of Mr. Heaters. These are the results of the company skimping on some aspects of production in order to keep the cost of their goods low.

Safety Options

Reznor’s UDAP series features a finger-proof protective feature enclosing the huge fan on the back of the heater, while Mr. Heater Big Maxx has a fully enclosed direct drive fan as standard equipment. Additionally, Reznor features a safety shutoff switch that, should it overheat, will immediately stop the gas supply.

Lifespan Of The Product

While the lifespan of a heater cannot be predicted, Mr. Heater consumers report that the product can last an average of 3-5 years. The frequency of maintenance and how frequently the heater is utilised both affect this outcome.

On the other hand, Reznor promises premium heaters that are made to last, and some customers report that their heaters lasted longer than the brand rival’s heaters did with no problems. Reznor offers one of the best warranties in the business to reflect their confidence in their products.

Warranty Protection

Except for their range of unit heaters, which have a 3-year warranty, Mr. Heater gives a 1-year limited warranty. These limited warranties only cover the repair of parts or products; they do not cover installation or any other services. If they decide that the problem is either normal wear and tear or was caused by bad maintenance on the part of the owner, they might decide not to cover your equipment under warranty.

No product registration is required to use Reznor’s warranty; all you need is the serial number of the item. Their UDAP/UDAS versions come with a 10-year heat exchanger guarantee and a 5-year warranty on replacement parts. Reznor, like Mr. Heater, does not pay for any expenses incurred during installation or for any other necessary services.

What Should I Consider Before Buying A Heater?

Determine The Correct BTU For Your Space

Knowing a heater’s specs and how many BTU it will require will help you choose the ideal heater for your space. British Thermal Units, or BTUs, are units of measurement for the amount of energy required to warm up a specific sized space. A 50,000 BTU heater, for instance, would be beneficial in a 3-car garage or a 32 x 22-foot workstation.

Choose A Heater With Less Noise

In comparison to heaters powered by natural gas or liquid propane, electric heaters are typically quieter.

Mounted heaters that are directed towards a room’s border or corner typically make more noise than those that are directed towards the middle. This is because the echo will be greater the closer it is to the wall.

Make sure the heater you select is appropriate for the use of the area in which it will be installed. For instance, a noisy heater will be a drawback in a private setting like an office or reading nook. A car garage or a simple storage room, on the other hand, won’t need a quiet environment.

Select The Appropriate Heater Size For Your Space

The size of your heater is crucial since choosing the incorrect size can result in higher utility costs than choosing the appropriate one. If you decide to save money and purchase a 25,000 BTU heater for a room that needs a 50,000 BTU heater, there’s a good probability that the heater won’t heat the area effectively and will also use more energy, which will ultimately cost you more money.

Which Heater Size Should I Get?

An improperly sized heater typically works harder, which might shorten its anticipated lifespan. Select a heater that is the proper size for your space to avoid future repairs and part replacement costs.

How Can I Determine The Right BTU For My Space?

A heater with 50,000 BTU is advised for rooms like a sizable garage or a workspace. Smaller spaces like a bathroom or bedroom just need a fraction of this space. In comparison to their heavy-duty counterparts, heaters made exclusively for tiny spaces are typically thinner and more portable.

The typical room sizes and the corresponding BTU are listed below.

  • 1,890 BTU = Family Bathroom (43 sq. ft.)
  • 7,465 BTU = Living Room (340 sq. ft)
  • 4,666 BTU = Double Bedroom (120 sq. ft.)
  • 10,500 BTU = Small Garage (200 sq. ft.)
  • 13, 000 BTU = 1-Car Garage (1,240 sq. ft.)
  • 18.800 BTU = 2-Car Garage (320 sq. ft.)
  • 38,200 BTU = 4-Garage/Basement (720 sq. ft.)

Please be aware that there are more elements to take into account when determining the ideal BTU for your room. Your climate region, ceiling height, and level of room insulation should all be taken into consideration because they all have an impact on the actual number of BTUs your space will need. Online BTU calculators can be useful for determining the best temperature for your particular needs.

Can I Put Up A Heater On My Own?

The best course of action for installing industrial-sized units is to hire a professional to do it for you. However, the majority of items made for household use are ready to be installed when you buy them, and they also come with instructions and a handbook that will show you how to do it.


Both Mr. Heater and Reznor have advantages and disadvantages, and the ideal heater brand for a particular consumer will depend on their unique requirements. We’ve talked about what makes a good heater and what, regardless of brand, is appropriate for the needs of your space. When choosing a heater, there are many factors to consider, so it is best to think things through thoroughly to ensure that your purchase will be worthwhile.
