EP Portable Heater

We all know that the cost of heating our homes will continue to be a significant burden on the family budget. Now millions of people are saving on their heating bills with the EP Portable Heater. With over one million satisfied customers around the world, the new EP heats better and faster, saves more on heating bills, and runs almost silent.

The EP has no exposed heating parts that can cause a fire. The outside of EP only gets warm to the touch so that it will not burn children or pets.

The EP will not reduce oxygen in the room. With other heaters, you’ll notice that you get sleepy when the heat comes on because they are burning up oxygen.

The advanced EP also heats the room evenly, wall to wall and floor to ceiling. it comfortably covers an area up to 350 square feet. Other heaters heat rooms unevenly with most of the heat concentrated to the center of the room. And they only heat an area a few feet around the heater. With the EP, the temperature will not vary in any part of the room.

The EP comes with a 3-year warranty(保修) and a 60-day. no questions asked. Satisfaction guarantee. If you are not totally satisfied, return it to our expertise and your money will be given back to you.
