Terrible customer service Terrible customer service. On hold incessantly. Heaters lost by FedEx. Spent 4 hours of my life trying to find them. They did not care. Sent me wrong hold address location. Happy to refund me only because they refused to pay for overnight shipping on new ones. Total nightmare. No empathy robot people. Hours of my life wasted. I would like to have reviewed the heaters but hey. God knows where they are weeks later.

Worried Issues; Customer Service Web site stated 1 to 2 business days to ship (but need to take holidays into account) Although ordered around holidays, order status was awaiting fulfillment. When I called customer service, another 12 days before fulfilment. Obviously, Haven't had a chance to review unit, but will if it arrives .

One of the 9 units I bought went bad in… One of the 9 units I bought went bad in 2 weeks . Almost impossible to replace . Terrible customer service

Just purchased our second Envi heater Just purchased our second Envi heater. The far bedrooms in our 2-story, single HVAC zoned-home get very cool in the winter. Even at a very low setting, the Envi is easily able to keep the chill out of the room, which allows us to keep the heating system at a lower setting overall. The second unit will replace a conventional oil-filled radiator that we currently use in the Master Bedroom. The Envi is easy to install (plug-in version), makes no noise, is energy efficient, and works really well! The build quality is excellent. This product is highly recommended!

Exceeds expectations by far! I bought one of their heaters several years ago to warm up a cold spot in my house it has been amazing! Heats up twice the square footage relative to what they claim and totally hassle free. Now the coldest room in my house is the warmest room and it’s perfect. I’m ordering another one for my shop. Saved me doing $5000 in duct work and putting in a larger capacity furnace!
