We were really looking forward to the gas heater, because we are open-air fans, it can be quite cold but with us at night - even in summer there are days that are anything but warm. Therefore, the device for us is worth almost the entire year. It comes in single commission about a meter high box, which is easier than you think and has to be built. The structure was a bit tricky, but to create. The commissioning was not a problem - we had a gas bottle anyway because of yet another furnace. Gas is simply convenient and inexpensive. The heater warms really intense. We have set it up in our furniture on the terrace and it was really nice and warm. The kids even had warm cheeks as we are purely :-) I'm curious to see how the instrument behaves in the long run.
