Re: Propane In-Floor Heat Operating Costs
Your winter fuel use in Therms is about design heat load / 42.
So if your heat load is say 42000BTU, you need 1000 Therms.
If you have a 95% modcon, that means about 1050 Therms of propane or 1100 gallon. So ~$3500/year.
You can do the above math for your heat loss. Generally with expensive fuel, it is worth while to get your heat load down, so see where you can improve your building envelope.
There is not much efficiency difference between a boiler or a condensing tankless. Efficiency is mostly a function of return water temp, so as long as those are low (~90-100F) you'll 90+ efficiency out of either.

Re: My three worst jobs sites. What are yours?
The worst was The grease trap in a fish store. Other than that any of the hundreds of hoarders that I've been to.

Re: My three worst jobs sites. What are yours?
This post makes me smile. Vacuum pumps are used in rendering plants, so yes, been in lots of those. Edible oil and shortening plants are slippery too. Really had to be careful climbing the stairs.
Sewage treatment plants too. They're not that bad, really.
Poultry processing plants use vacuum pumps for evisceration. Really nice when we'd get one in for repair that had been baking in a hot enclosed semi trailer for a day or 2.

Re: HVAC in New Construction in 2024
54% of new homes the primary fuel is electric, resistance or heat pumps.
All I can is get ready for brown outs as the electrical grid isn't going to hack this.
Seems steam and oil are not popular LOL
