Tankless Boiler -- Weil McLain?

Could U please explain what the "restrictor" is and where in the system it was located? I have alot of boiler experience and have never heard of this.
I'm wondering if U mean a water regulating valve perhaps? Its purpose is to knock down city water pressure (normally 70 psi) to household pressure (approx 30 psi)
If thats what he removed then while hes solved the original problem, he may have given U some new ones.
The water now moves thru the boiler to fast which means it requires more oil to heat it up and the pressure out of your faucet is to high. Not life threating but it might hurt young children or older folks in the shower.
Ur hot water heating system is now at city pressure. Most residential boilers are equipped with a pressure relief valve normally set @ 30 psi. If pressure in the system goes above that setting it relieves that pressure. There should be a pressure gage on the boiler and in most cases it should be @ 12 psi.
Let me know about the restrictor. I'm curious.
If u have hard water then U might want to go with a water filter/softner combo unit(expensive) or just try a filter (cheap) on the main water line into the house. Something down to about 3 microns should do the trick.
Hope this helps:)

The valve that had to be replaced was also totally corroded the screw that held it was simply broken off -- the plumber suggested that I take the valve to the city water office and ask what they were doing to soften the water. As I said, the boiler is only four years old, and the valve and restictor are corroded and totally eaten away. When we first moved here, the water company gave us stuff to put in the tanks of the toilets to take the iron out of the water -- the tanks were turning dark brown. We don't have to do that any more -- the water company did something fairly recently to improve water quality -- so maybe it was thr previous water situation that created the problems with the boiler to begin with.
Is it difficult to install the filter system you're suggesting? The cheap one?
Thanks ever so much for you interest and response.

Its been a long time since I've done residential work. The restrictor must B something new that I'm not aware of. My feelings are that if a system was built with something in it, then it should always have it, but thats just me.
If U are completely happy and notice no adverse effects then I think Ur ok:)
As far as the filter, no their not hard to install. It may require some soldering on Ur part if U plan to do it yourself. If not I think a reasonable cost is $400.00-600.00, but I believe they are well worth it. But filters only remove particulates from water. They do not remove dissolved minerals (hardness). Only water softners can do that.
Hope this helps:)

Actually now that I think about it, there is a mixer valve (maybe northeastern for tempering valve? ) -- the first plumber talked about replacing it to see if it was the problem, but he couldn't find one -- said the company didn't make them any more.

This will be especially true when the boiler sits idle at it's low limit setting (140-160 degrees).
The flow restrictor is a common addition these days with the lower mass of today's boilers.
A water softener is a must for you, because it's only a matter of time until the coil itself becomes restricted with deposits. When that happens, you'll need a new coil or an acid cleaning.
Hope this helps
