Absolutely not! This kind of question came up a lot, and it’s totally understandable. Everyone wants a cozy, quiet room, not a cold, noisy one. Unfortunately, most portable users in the market are usually made of the type of plastic that makes a lot of undesirable noises, which is not ideal in most cases. Instead of keeping you warm and making you feel comfortable, these portable heaters annoy the living hell out of you. Lucky for you, as several EcoHeat reviews show that is NOT the case with this product. For our EcoHeat review, we put it to the test. The result shows that the EcoHeat makes such a minimal sound that most of the time, you won’t even notice it’s there. The sound it makes is way below 50db, which won’t bother even people who are hypersensitive to sound. The silent operation of this portable heater makes it a perfect choice to be used anywhere.
