I've had a Heiss Heater for a few months now. Its the middle sized unit. I started having problems from the get go. I have cracking in the concrete, leaking smoke around the warped door, copper pipe showing inside the firebox, chunks of concrete breaking off, and crumbling in my hands.
Note, I've had this a few months. Not years, Months. This hasn't even made it through one season!!!
I had an HVAC tech look at mine, and the first thing he noticed was the lack of pressure relief valve.
I go through more wood than I went through with my last boiler. And thats after adding insulation to my house this year!
The pump they recommend is not big enough. We had to purchase a larger pump. The multiple elbows in the copper, extend the amount of pressure you need to push the water. Each elbow adds 30ft and that means you have about 500-600 ft.
I have a friend who bought a larger unit after I bought mine. He cannot even use his anymore. His pipe burst inside the cement and he couldn't get heat off the unit. Now he is burning fuel oil again to keep warm.
Heiss is not standing behind their warranties. My friend didn't even get a warranty. I was "luckier" although they refuse to admit anything is wrong with my unit, still, and won't replace the warped door either.
Cheaper is NOT always better! Unless you want to buy a new one every year!
