My old, high-end heater finally quite after 11 years of faithful service (with routine maintenance & repairs) so I decided to replace it with a top of the line FireSense model. I did a lot of research and although many heaters look the same, it became very obvious that the details matter. This Pro Series heater is very well made with high quality materials and the workmanship is excellent. Assembly was very easy and took less than the hour stated in the instructions. Once it was put together, it fired right up and functions flawlessly covering my entire patio with warm radiant heat. The wheels work surprisingly well compared to my last heater and stainless finish is a welcome improvement over the dull, faded paint on my old unit. I actually prefer the tank cover that lifts off vs the door that my old model had - it's very easy to change tanks and will be less prone to damage over time. I'm looking forward to many years of service from this well built heater.
