Re: Converting from oil to gas Eastern PA
What’s the gas cost? Oil is expensive but you’re only using .2G per heating degree day so important to make sure you don’t spend $10k to save $500 annually.
Re: New Boiler Overfilling After Warm Weather
Yes. The Hartford loop should connect at 2"–4" below the normal water line. Yours is about 2" below the return, which is essentially the bottom of the boiler. If the water drains to the bottom of the Hartford, your boiler will be empty.
As long as they're re-doing it, consider a Gifford loop instead.
Re: Installing wifi-smart thermostat with 2-3 wires hydronic heat-only
You need to reverse the Red and White wires
The red wire is on Tw. and the white wire is on TR. This makes no difference when there is only 2 wires. But it makes a difference when you have 3 wires and one of them is common.
Look close at the red and white wires on the zone 6 label. The left is for the White to W on the thermostat. The right one TR must be connected to R.
Re: My pressure gauge is between 20 to 25 right at the marker. Is that too high!
You have no need to turn off the power supply or close any valves. Just connect a hose, open the valve slowly and watch the pressure gauge. Take you three minutes (or less) to bring it down to 18 psi.
However, it's already off from last night. Just leave it off and bring the pressure down with the hose and the valve.
BTW, what is the pressure this morning with the boiler dead cold? It might be down below 18 psi already. If so, lower it to 15 psi.

Re: The "equalizer" is mis-named. It does nothing to equalize anything.
And when you finish the first page of that application @ethicalpaul, page 2 needs

Re: The "equalizer" is mis-named. It does nothing to equalize anything.
Perhaps that's where the name equalizer comes from.
It equalizes the negative pressure when the pipe breaks so it "vents" the loop and stops it from siphoning from the boiler. It never had anything to do with equalizing positive pressure when the system is intact and never actually does anything to a properly functioning system.
I've brought that up a few times, but didn't think the name had anything to do with it until now.
