NO HEAT OR HOT WATER BOILER NEEDS SERVICE PART 1 OF 2

If the Taco control has a priority switch, maybe mentioned below the hot water has to be satisfied first . So if the circulator for the hot water is bad, the control will not be satisfied to allow heat to the other circulators- no 120V. When you replace hot water circulator, the Taco will allow the other heat zones to work. That might be the issue as others have mentioned.

It is so satisfying when Steve bleeds the air out of the line to check the oil flow, literally ASMR.

Good to see another Steve's troubleshooting videos!

Bio Slime “It’s alive” somebody save us!

I look forward to your videos.👍

Hey Steve and Miss Molly! Workin’ again ya’ll. 👍👍

Steve how about a Sunday, St. Patrick's Day special Maybe as you are quite the cook, show us how to make Irish turkey, or dress up our four paws friend in green.

look forward to paaaaart two; see you on the morrow!

The issue with stuff added to stuff is rich get richer while We The People, well sheep actually just tolerate it. And so it goes on.

For everyone talking about priority, he literally jumped it out and bypassed all of that and you could hear the relay click and it still didn't pass any power. There's probably a bad solder joint or something on the board.

What up Steven thank you for all your videos I learned a lot for you

I love my Viessmann triple pass boiler !!

Steve must moonlight at jiffy lube and Walmart the way he cranked that filter on there...yee haw mama cranker down lmao😅😂😢😊🎉

More Molly, more Molly, please show more Molly.

my heating oil filter i change every other year and its still good, we dont have that bio stuff here. & i change the nozzle each year. then of course what ever is needed as needed. its just a basic forced air mobile home furnace. pretty simple.

Hello Steve and Miss Molly 😊👍🏻 Texas Lady🖐🏼

Hello Steve!

Howdy Steve and Molly

Hmmm, with a burnt board and a dead circulator, I'm betting on a power surge. Wonder if the guy's TVs went out around the same time.

I don't have a problem with biodiesel. Ran it in my car for years when I had a diesel car. Ran it in boilers in several houses for many years as well. It's not an issue if the correct filters and piping are used. 1 pipe system is a bad idea, sludge will build up in the bottom of the tank if the oil doesn't circulate. With 2 pipe it doesn't. Double filters are a good idea as well. Make sure to use the bio rated filters, the others have rubber that reacts badly with the fuel. Certain nozzles don't run well with the fuel either. Hollow (A and H) are a bad idea. Delavan regular solid (B) tend o have issues too. Nozzles with brass components also don't work as well. The best to use are Hago B and SS, Steinen S and Q, and Monarch A and AR. Danfoss is coming out with special nozzles now, the HVO series. Do the right things and there are no issues. My mother's house has been running on B100 for years. Double filters on each appliance. Furnace has an ancient Beckett SR with a J pump. Never has an issue. The point is, MA is going to ban oil at some point. They can't ban biodiesel because it's carbon neutral. They're already going that direction with gas. Would you rather change your filters once a year or heat with those stupid heat pumps. I know what I would rather do, I like my oil heat and I'm not getting rid of it for any reason.
