    I recommend this product

    Ready for winter!!

    Excellent product. Looks great, slimline is the way to go.....half the width of the Bromic I bought and had to return. Single element but still needed 240V line run with its own fuse. Have not been able to verify the comfort level in cold weather yet but it puts out strong heat.

    Good heater

    I was very impressed with the customer service of this company. They helped me select the right size before I made a purchase.



    We installed 3 of these in our patio. They work great and keeps us comfortable during the cooler times of spring and fall.
