Re: First time doing heat load calc: Whoa, is my boiler 2x oversized?
A simple cheap blower door test WILL show where the cheapest and highest return on investments can be made.

Re: Electrical - heating question
The NEC disconnect can be a switch on/near, at least in-sight-of, the equipment. Most burner instructions (and every burner tech I met) require a disconnect within reach of the service side.

Re: First time doing heat load calc: Whoa, is my boiler 2x oversized?
After lots of measuring and calculating and filling out the form I got about 70,000 btus/hr. So now I've pinpointed my desired energy capacity to exactly precisely somewhere between 30,000 (fuel bill method) and 70,000 btus (this method)
yeah this is exactly why you should not calculate it by the assembly lol. Way too inaccurate to use for someone who’s doing it for the first time. Why not just trust what actually happened? Otherwise you’re relying on a bunch of guesswork.
Regardless, you know what to do now. Reach out to some contractors and good luck!
Re: UPS26-150F speed shaft broke
do you need to be able to change the speed? If not just wire the speed you want and skip the switch

Re: Honeywell VisonPro 8000 cycles per hour
No, that kind of rapid cycling isn't normal. If it was the thermostat switching on and off even though it reached the setpoint, that isn't normal either. Something got badly confused…
There are some steam systems which seem to work better on 2 cycles per hour, so you could try that. 3 cycles per hour may be too short a cycle to get heat to some of the slower radiators.
Re: Sanitary sewer pipe thru box culvert?
This is something DPW or DOT engineers should be advising you on. Wasnt it in the bid specs? Mad Dog
Re: Sanitary sewer pipe thru box culvert?
"Now knowing this ……..I'll bet I'll be allowed to bury my 2" pipe within this stream bed as is done throughout the township in this area.
…….. thoughts on this?"
Fuggedaboutit.
Even if you could get permission — highly unlikely — you don't want the liability
Re: Sanitary sewer pipe thru box culvert?
It's done. But this isn't a matter of some Code or other. You don't own the culvert — the State does. I would imagine that you might be able to negotiate with the State Highway Department to purchase an easement through the culvert. You, of course, would then be responsible for any damage to the culvert and, very likely, all repairs and maintenance, and quite likely the resulting damage from any blockage or reduction in flow in, for instance, a flood.
As well as, of course, any harm to the stream should your pipe break or leak and cause pollution or contamination.
As part of your initial application for purchase of the easement, you would also have to show that your activities would not in any way harm the culvert or reduce the flow, have any impact on the stream, nor any impact on the highway.
And you would have to provide liability insurance covering all that.
You got the money to do all that? I'd suggest a bond of somewhere in the mid seven figures to start, and a couple of million up front for the studies, and an eight figure liability coverage might do…
Re: First time doing heat load calc: Whoa, is my boiler 2x oversized?
I agree with @Steamhead that you calculation sounds too low. It may be accurate but I would do further calculations by some other methods to cross check
Re: First time doing heat load calc: Whoa, is my boiler 2x oversized?
Most residential boilers are two to three times oversized.
