Query: Heat? Heat what?

This is the poorest excuse of a patio heater. Stay away! We have it next to our hot tub. Thought it would help after exiting the tub. Ha! What a waste of money. Best advice we can offer is go to your local LP gas dealer for sizing your patio heater for your part of the country. We have been in the pool/spa business for 32 years and have seen a lot of inadequacies. I have to say that this is the first time getting bitten this badly. Bottom line.....Don't waste your money here.
