Envi Heater Room Sizes - What’s the Right Size?

Posted by

Bookmark and Share

Lately,tThe number one question we get asked is “How big of a room cam the Envi heater work in and how hot will it get?” Here is an introduction to the heating size ratio and the temperature of the Envi Heater.

The Recommended Ratio

The Envi is designed to heat an average room of around 10 by 15 feet; this translates to roughly 130 - 150 square feet (insofar as the room is properly insulated). Our 475 watt Envi Heater was designed to heat your room to a comfortable level, even in the coldest regions. Rooms that have inadequate insulation or a lot of windows are harder to heat up, and you will need to adjust the number of heaters used accordingly. You can add as many heaters as you want to heat rooms of any size. If you choose to heat rooms with little to no insulation (or even a fully-windowed sunroom), we recommend a ratio of one Envi Heater per 60 – 80 square feet.

The Temperature Range

The general temperature range that you can expect is between about 65 - 75 degrees depending on the room size and insulation. In a normal bedroom with modern day insulation the room temperature range of the Envi is about 40 – 85 degrees. This is thanks to Envi's built-in thermostat or, alternatively, a wall thermostat. You can always call or email our team to help you if you need more detailed answers for your situation.

Customer Reviews

Silent Heat – This unit was extremely easy to install on the wall. We have oil heat/forced hot water. We needed a secondary heat source for a child's bedroom. This Envi High-Efficiency Whole Room Plug-In Electric Panel Heater produces heat keeping the room at a constant temperature of your choice. It is also a silent heater. It is the answer to our needs. Happy with the purchase.”

Sleek and functional design – My brother purchased two of these last year. He raved about them. I needed a small heater for a 170 square foot detached office space. This heater does the job to perfection. No more dragging in my portable heater that was ugly and space-consuming. The Envi heater is slim and unassuming, yet tastefully designed. The nights are chilly and the room is staying quite comfortable. Easy to install, helpful template and instructions. Timely delivery.
