Which of the following options makes sense to get?
1. Thermo Ash Monitoring Control - Does this really help? Especially while running during the summer under light load of DHW only??
The AHS web site has not kept up with the coal gun product they are now selling. As I understand it all now sold are Thermo Ash

Again all are now UL listed
watkinsdr wrote:3. ASME Rating - Help with insurance too? Plus a requirement in some states, right?? Probably helps with resale value too???
All are designed to ASME specs. The option is the boiler pressure vessel "H Stamp". YOU
need to determine if your state requires it. In a residential use PA does not require it. Call your local code inspection officials and get the answer in writing.

The belt drive fan does lower the temperature at the motor, but in my opinion what will likely fail is motor bearings and they are cheap compared to the belt drive option. The motor bearing fails because the heat boils out the grease.
