I’m not happy with it

My home working space is currently heated by a compact, ventless gas heater, but because the house is nearly 200 years old plus lacks conventional HVAC duct, it’s problematic to heat plus cool, and the advantage of the little heating system is that it doesn’t take up much space or require any venting capabilities, however despite the small size, it puts out a great deal of heat! With truly long Winter seasons and hot and cold temperatures well below zero, the ventless heating system carries a truly demanding workload; I’m not entirely content with it.

It is a single stage heater, which means that it can only operate at full capacity.

There is no way to adjust the speed. The heating system is either on or off. When the temperature in the home office drops below the temperature control setting, the heating system kicks on. It then blasts a tremendous amount of truly tepid air non stop, then once it is able to hit the desired temperature level, the heating system shuts down plus blows freezing air to cool itself down a bit. This creates truly unpleasant temperature swings. The ventless heating system features two separate air filters that need to be consistently cleaned. I make sure to clean them at least once per week. If even a small amount of dust accumulates in the screens of the filters, an orange light flashes on the control panel of the heater. When this happens, the heating system will no longer shut itself down. It more or less runs non stop until I manually shut it off. I’m concerned that the idea will overheat and then create a safety threat. There’s also the issue that the heating system causes an oily motion picture on our windows. I have a set of French doors separating our home office from the dining room! Each of the two doors features 12 small panes of glass that I frequently need to clean.
