The built-in thermostat compatibility was also a game changer for us-it offers that extra touch of convenience, allowing us to maintain a consistent temperature without constant adjustments.
While we did have a few hiccups during initial runs, such as small amounts of smoke when it first ignited and an occasional need for injector replacement, these experiences were manageable. After switching to a premium fuel additive,not only did it eliminate the frequent need to use the pump between uses,but it also made the whole system run quieter.These efficiency upgrades and improvements are a testament to the quality engineering behind this heater.
