To do one heater in a perfect world where the room is water resistant roughly $245.00 includes new gasket.

For one ignitor installed $214.00

The room has a floor drain 3 feet away from the heaters.

At those prices I would prolly sub it out. I think I was quoted something like $125 just for the ignitor plus shipping and tax.

I just don't see how you can pay to drive out there, drain the heater down, pull the access, manually remove the scale, then treat the flame coil (chemical costs), supply and install a new gasket, fill the thing back up and test fire it all for $245.

Why are you looking to de-scale W/H? Don't you want them to fail so you can replace them?

I think he means anything that is not on the street where his office is located.....anything past that point is "Out there". But he could mean anything outside of his garage

I wouldn't even touch it for 245.00 so I know he wont down in central FL.

How much calcium carbonate does RO water dissolve at room temperature? I know that acid neutralizers for well systems use calcium carbonate and the chemical must be replenished as it is dissolved away by the acidic water. I was just wondering how practical it would be to use RO water to descale a boiler.

Let’s say hypothetically that 1 gallon of RO water at room temperature will dissolve 5 grams of boiler scale. That would mean that you would need only 200 gallons of RO water to dissolve a kilo of boiler scale.

Why does this matter? Well, what if a small RO unit could be installed in a boiler room with flush rigs built into the boiler piping. When one of the boilers starts popping you simply turn the isolation valves off to 1 boiler and open the RO purge valves and walk away. Come back a few days later and all of the scale will be dissolved away. Switch to the next boiler and repeat. Once said rig is installed, boiler maintenance is cheap.

Thoughts?
