Re: Replacement Gas Boiler Size
Why 95%?
You'll only see that when running low water temperatures. Less than 140°F. Your emitters are rated for 180° water.
Your old boiler is probably 85% efficient and lasted over 40 years. The highly efficient won't last 1/2 that!

Re: Is this a house trap?
With all they currently have going on, why do you want them to do a radon test?
Even if it is a concern, with the dirt that saturated with water radon levels would likely be low especially if that's clay.
I wouldn't open up another can of worms until the problem at hand is sorted my self.

That's what we were saying. Once again, the sewer & drain company SHOULD know this. What's the next step? Mad Dog

Re: Off grid heating/ac minisplit efficiency
Mini splits don't have the inrush of typical AC unit as all the bits are inverter controlled. They do ramp up to near full power when doing periodic oil recovery but as long as you size for max power, you should be fine.
One thing to watch in off grid is power quality especially in remote areas with lighting. Make sure you have surge protection on your main panel and the AC itself.
For off grid, you want heat that is guaranteed to work 100%. Generators have a nasty habit of not starting when you are not there, so can't be relied on for power for heat (your boiler and pumps need surprising amounts of power once you calculate it). Best to install a pilot operated heat source such as a through the wall vented heater that can keep your place from freezing even with power out.

Re: Old house heating: Steam radiators or forced air?
"The reason for switching to central would be get to rid of the boiler in the basement and make it a mud room"
Done correctly, you'd be replacing steam pipes in your basement with much larger ductwork. 🤔
Re: Old house heating: Steam radiators or forced air?
Got a 2022 Hyundai Santa FE fairly loaded I think it was around 35K 3 years ago. I am well aware of new truck prices. I drive a 2007 F-150 5 speed 6cyl.
The engine crapped out at 145K. I paid only $6000 for it 9 years ago it came up from TN so the body will last me out. I looked at the prices of new trucks, excise tax and insurance and I only drive it 6k/ year so it was a no brainer to put a boneyard engine in it. My mechanic agreed because the rest of the truck is in good shape
Used truck prices are even more horrifying. 20K won't get you much unless the buyer thinks that 150-200K is ok for mileage and you still have high insurance and excise tax
Besides I will never give up my 5 speed. They don't exist in new trucks.
