I thought they would stand behind the Samson valve and chain . They charged me $132.00 , If I wanted to try the air vent blower kit , that was another $230.00. Now on the domestic coil leaking they did tell me to crank it as hard as I could and goop it good ,wrap it with teflon also. They also said they are prone to leak when the boiler is not up to temp. and they are right. I did that twice. No fun moving a 1200lb boiler away from the wall. I added additional SS stack, purchased a digital manometer documented all readings, purchased coal three other dealers. What more can I say. I want to finish my boiler room and block up the sides for my bathroom in this new building before summer is here!
I have yet to hear any one praise the performance of the DS boiler or show me documentation of the BTU output or recovery of the unit. Heck I have not even seen a installation or operation manual . I have searched the web ,talk to people and have spent more $$$ than I paid for the boiler. I always say if you throw enough money and time on something it will work. I think I may be wrong on this one. I do not want to say the boiler may not work for someone, heck I gotta sell it.
