I chose this heater for its smart functionality, as I wanted something I could control remotely to heat up my garden room on colder days when I have excess solar power to use.On its highest setting, it heats small spaces very quickly, which is perfect for my needs. It’s also very quiet, even when running at maximum power, so it doesn’t disturb me while I’m working. I mostly use it on the maximum setting to warm up the garden room quickly, and it performs brilliantly.The app is nicely laid out, making it easy to use the smart features like remote control and adjustability. The range of heat output options gives plenty of flexibility for different situations.I have yet to test the safety features, but so far, this heater has been excellent for my purposes. Overall, it’s a well-designed, efficient, and reliable heater that’s ideal for small spaces. Highly recommend it for anyone looking for a smart heating solution!
