Cirrus owners opinions

I have an 820 and I like the heat more than a furnace. The heat comes from everywhere,under sink, dinette, shower, around bed, runs thru the basement(little radiators not just the lines) and on the way back to the reservoir heats outside storage. The first time you use it you'll smell the tubing but falls off quickly with each use. This is our second one and the wife was concerned with the sound coming from the closet as you can hear the fluid going back into reservoir.
