Re: New Rinnai boiler overheating very quickly but no hot water?
Shut it off and don't run it until you get the water flow issue resolved. 245 is way too hot.
You're going to damage something if you haven't already done that.
Re: New Rinnai boiler overheating very quickly but no hot water?
Does your boiler have a built in pump? Quick google of diagrams show external primary pump.

Re: New Rinnai boiler overheating very quickly but no hot water?
Well… I believe I am looking at the correct manual. Where is the Boiler pump in your install ? It acts like there is no water flow through the boiler. No boiler pump (circulator) #11 below.

I wouldn't use either one on steam if I had the choice.
Re: Boiler explosion in White Marsh, MD
I may be wrong but the lack of moisture and the cast appearing intact, it looks like a gas/burner explosion. Glad he survived.

Re: 1966 heating oil tank
You’d be crazy to try to clean. 1966 tank.
The sludge is probably the last thing keeping the tank from leaking.

This is another case of "just because you can, doesn't necessarily mean you should".
Re: Steam device to be identified
You might actually have it- depends on what's inside the radiator valves.
Re: Mega press for steam question
I've used 3" mega press for a few repairs on a main. With this job it was the best option to avoid a major project. You have to specify the right fittings and ensure the pipe is supported correctly. It has its place, just not fond of using it for every fitting during a changeout. 2 1/2 and 3" mega press flanges and couplings have saved the day on a few jobs to make the transition to near boiler piping where threading in place would not be practical or increase the cost for the customer by a decent amount.
Re: Mega press for steam question
Not a good idea to use MegaPress on steam, since it's too easy for the fittings to sag over time. And we know what that causes……………
