How often should I perform maintenance on my greenhouse heater?
I've been using a propane heater in my greenhouse for my bonsai collection, and I want to ensure it’s running efficiently throughout the colder months. I’ve heard mixed advice on maintenance schedules, and since I'm meticulous about the health of my plants, I want to be proactive. I've checked the filters and connections for any visible issues, but I’m curious about how often I should be performing detailed checks or servicing it to prevent any sudden failures. What’s a reasonable maintenance schedule for a propane greenhouse heater, and are there specific signs I should look for that indicate it needs attention? Thank you!
