In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
1906 water boiler converted to natural gas.
My client purchased this home under the assumption boiler worked.
I found it has a water gauge on top left and a small possibly broken temprature gauge on top right.
There is a floor standing expansion tank with no vents that I can find.
The only control other than a heating thermostat and thermocouples on the gas valve.
Shouldn't this have a Aquastat and low water cut off?
What water pressure should we have.
