Enviro Pellet Stove Reviews

Pellet stoves have emerged in the last few decades as an excellent option for reliable and affordable heating. Since they hit the market in the early 1990s there has been an explosion of different manufacturers and styles of pellet stoves. In this article, we will focus on one particular brand—the Enviro Pellet stove. 

With many pellet stoves on the market, it can be hard to determine which one might be right for you. To help you sort through the details we have compared the Enviro pellet stove to several other leading stoves on the market. We looked at their price, features, BTU rating, heating area, pellet hopper size, and even broke down a few pros and cons. 

At the end, we have also provided an overall rating for the Enviro pellet stove as well as a top pick from the list of stoves in this article.

About Enviro Wood Pellet Stoves

Enviro leads the pellet stove marketplace with some of the most powerful and cutting-edge designs available. They offer a range of models from traditional hearth-style pellet stoves up through pellet furnaces capable of heating very large spaces. The Enviro pellet stove creates heat by burning small pellets of compressed wood in an enclosed space and then blowing that heat out into a room. 

The wood used in pellets can vary greatly, but these pellets are traditionally made from recycled particulate that is generated in the forest products industry. The pellets are packaged into 40-pound bags and then sold on the general marketplace for use with pellet stoves.

To operate the Enviro pellet stove the pellets are loaded into a hopper. It then releases a small number of pellets into a firebox that faces outward into the room to be heated. These pellets are then ignited by hand or with an automatic lighting mechanism. 

Once the pellets have caught sufficiently and have a good amount of coals, the stove is fully engaged. Pellets then move automatically from the hopper to onto the flame to keep the fire burning. The rate at which pellets are fed from the hopper is controlled by the user. More pellets introduced to the stove will create a larger and warmer flame while the opposite is true with fewer pellets. 

Simpler pellet stoves often rely on the user to visually monitor the flame level and warmth. On such models, you control the pellet feed either with analog dials or digital controls. Some higher-end models use internal thermostats and pre-programmed heating specs to maintain a constant temperature without the need for much maintenance. To discontinue use of the Enviro pellet stove, simply stop the pellet feed and engage the stove's shut-down process. 

Pellet stoves are very durable and highly efficient but, like all wood burning heat sources, they require some maintenance. Regular removal of ash from a collection bin is required and some ash may accumulate on the glass surfaces. This ash can be cleaned with a damp paper towel and glass cleaner to restore a full and inviting view of the flame inside the enviro pellet stove.

Enviro Pellet Stove Product Specs 

For this article, we decided to focus in on one specific Enviro pellet stove: the M55. This is a large and powerful pellet stove that is big enough to warm an entire small dwelling like a cottage or cabin. It could serve as a reliable secondary heating source for a larger space like a house, retail space, or office. It has a large pellet hopper capacity at 80-pounds, so you won't need to spend all day refilling the hopper to keep the stove running. 

With a 55,000 BTU rating and a 2,500 square foot heating area, this Enviro pellet stove pumps a lot of heat. It's not just powerful, however, as at it also has an 83.5% efficiency rating from the EPA. This means that the pellets in this stove burn to 83.5% completion and release a very small quantity of smoke, ash, or particulate out through the exhaust vent. This high-efficiency rating is not only good for the planet but also makes your pellets go further than they would in a less efficient system. 

Besides its powerful heating capacity and efficiency, this Enviro pellet stove is easy to use. It can be coupled with an internal thermostat or wired to an external thermostat for simple and consistent heat throughout the day.


Prices on pellet stoves can differ depending on size, features, and season. The pellet stoves in this article range in price between around $1,200 and around $4,000.

The 4840 wall mount pellet stove from US Stove is much smaller and more compact option compared with the Enviro pellet stove. As the name implies, this is a wall-mounted unit, and it vents directly to the outdoors through the wall. This will take up far less space than a freestanding pellet stove like the Enviro and could be a great choice for additional heat in a smaller space like a living room or upstairs hallway.

Overall, the 4840 is a less powerful unit than some on the market. It has a 28-pound pellet hopper and burns at a max BTU of 24,000. Though this wouldn't be a great choice as a primary heat source for a home, it could be an excellent addition to a home that already heats with pellets and has a good stock of fuel on hand. It's also very easy to operate with five different heating modes as well as an auto-ignition setting. It will run for six hours straight on high and 24 hours on low.

Mounting this unit could require some expertise, but you get everything you need including a mounting bracket, stove adapter, cap, wall thimble, vent attachment, and twist lock pipe.

Compared with the other units on our list, this Enviro pellet stove is more of premium option and has the price tag to prove it. It's one of the highest priced pellet stoves on the market. This fact alone could rule the stove out for some buyers. But for those needing a lot of heat and are willing to pay a little more for extra quality features, this could be an excellent choice.

Overall Top Pick: For the money, our overall top pick of the pellet stoves on this list is the Castle Serenity. It's slightly underpowered, but we feel the programmability more than makes up for it.
