Great heater

Really is a great heater. Bought one in 2016 and had it exposed to the elements year round and didn’t even cover it in the winter. 3 years ago I replaced some burners as I let them rust. Recently I started to get error codes that would suggest I needed new boards and such. I decided to buy another one and Sunplay had the best deal. Had my heater in 2 weeks without any hassle. I decided to buy a lean-to perhaps keep some of that direct rain off of it. I will also wrap it in the winter to protect it further. This one has Bluetooth so looking forward to that. The gas and electric hookups are oriented a little differently, but shouldn’t bee a huge problem. The water inlet and outlet are in the same place THANK GOD! Looking forward to many more years of warm bath water in my pool. Worth every penny spent on the unit and the enormous amount of gas it goes through. I can open my pool with 54° water and swim in 90° the next day. Great heater!!
