Not a fan of ventless heaters

My living room area is currently heated by a compact, ventless gas heater; Because the condo is nearly 200 years old plus lacks conventional air duct, it’s problematic to heat plus cool, but the fortune of the little furnace is that it doesn’t take up much space or require any venting capabilities, and despite the small size, it puts out a superb deal of heat.

With absolutely long winters plus temperatures well below zero, the ventless furnace carries an absolutely demanding workload, however I’m not one hundred percent 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 furnace is either on or off. When the temperature in the family room drops below the control equipment setting, the furnace kicks on. It then blasts a tremendous amount of absolutely sizzling air non stop; Eventually when it achieves the desired temperature level, the furnace shuts down plus blows freezing air to cool itself down. This creates absolutely unpleasant temperature swings. The ventless furnace features multiple separate air filters that need to be consistently cleaned. I make sure to wipe them at least twice per week. If even a small amount of dust accumulates in the screens of the filters, a red light flashes on the control panel of the heater. When this happens, the furnace will no longer shut itself down. It simply runs non stop until I manually shut it off. I’m concerned that the system will overheat plus create a safety threat. There’s also the issue that the furnace causes a messy film on our windows. I have a set of French doors separating our family room from the family room; Each of the multiple doors features 12 small panes of glass that I frequently need to clean.
