Hard water to Soft
If you run a boiler on hard water for 2 years, then flush and fill it with soft water, will the new soft water eventually remove the scale that must have built up in the boiler????

My 60-year-old hot water heating system shows no evidence of scale or corrosion when I have opened up the system for maintenance.

I though hard water wasn't good for Brazed Plate exchangers???
The point that Furd made is that 'lime scale' (it's just called that, it's calcium and magnesium) is only a problem when water is constantly being added to a system.
The amount of 'hardness' in a single filling of a boiler is not enough to cause a problem. It's the constant supply of fresh water entering a system that causes a buildup over time.
If your system is leak free, you only fill it once...
Still, with the tiny passages in a HX, they do occasionally need to be acid flushed. And the buildup may not be on the 'boiler' side...
Where is this HX in your system? Connected to what?

It's mounted directly on the top of a 55 gal Versa Flame boiler.
Which brings up another problem. It runs hot all day, despite no actual use of hot water due to thermal syphoning. If I close one of the shutoff valves (there are two), it cools down, and, remains cool till I open the valve, and, use some hot water.
It drains enough heat out of the boiler when not being used, to cause the boiler to fire at least twice during the day, on top of the boilers normal firing rate.
You would think a company as advance as HTP would have built anti syphoning into the DHW system.
Any easy fix for this. It's a pain in the butt turning the valve off and on all the time when I want hot water.

In the end, while it's easy enough to say that they should have designed their products so that they were "installer-proof", bottom line is that any install is only as good as the installer!

I did the install myself.
The HX came factory installed and, pre plumbed on the boiler.
I'll try and take a couple of pics tomorrow.
Here's what it is

On the question about the HX, after looking at that manual, and reading the manufacturers warnings about water quality and chemistry, and seeing that your hard domestic water flows through one side of the HX, I would say there's a good chance that the HX is at least starting to scale up.

Yeah, that was a concern. Would running soft water through it from now on help clean out the Domestic side of it????
I'll prolly take it off next summer and soak it in vinegar for a day.
Would still like to remedy the syphoning. There's not much room pipework wise to install a check valve. I might have to make, or, modify something to fit in an existing piece of pipe.
I notice the new Taco Bumble Bee has a built in check valve. If they sell that separately as a part, I might be able to retro it into the existing Circulator.

Household vinegar works fine on my shower head, and, toilets.
About every three months I get a pretty hard coating (stiff brush won't touch it) of greyish calcium buildup in the toilet bowl. One cup of vinegar overnite softens it up, and, very light brushing, scrubs it up nice n clean.
Is the stuff in the Brazed Plate going to be any harder than the toilet/shower head buildup, maybe because of the heat involved.
