    great patio heater

    This is a great patio heater. It works well, not hard to install or use. The only complaint is that there is no way to control the heat to high or low. Just the one setting. But I like it and it's just what I expected.

    Great heaters

    My customer loves the heaters. They really helped the new enclosed patio. Great even heat threw out patio. We put a fan out on patio but they are not using it.

    If you're looking to add heaters to your outdoor living spaces, this is THE heater. It's used at so many of the outdoor restaurants here in Phoenix where outdoor dining is an asset to any restaurant. I'm proud to have two of these warming my outdoor living dining area. In the cooler months, I love having coffee and meals on the patio and taking in the view of the mountain. The heaters light up immediately using the remote. And that have two settings (high/low). Easy to operate and a beautiful addition to our home. Just love them.

    The heater arrived well packaged and on time as promised. We had chosen the black-coated version with electronic ignition to blend in with our decor. All in all the heater works well. We had it professionally installed as the installation is a bit tricky
