Central Boiler / Loosing water mystery SOLVED!
« on: December 09, 2018, 10:25:52 PM »
Our E Classic is 6 years old this year. Never had problems with it until this season. I take care of my baby by cleaning it inside and out after every season. Checking and cleaning the air elbows and lubing the solenoids. I've never had to add water till this season. The water level was at the full line in the beginning this season. now every week I need to add water. There is no signs water leaking from the outside anywhere. I have noticed that I am getting great burn times as long as 16-18 hours. weather has been highs in the low 30s and lows in the upper 20s. also noticed that the reaction chamber is higher than I have seen the past. Its getting as high as 1.40 and water temp of 185. I since replaced the fire box door seal, that was in bad shape. Tested and lubed the solenoids all we around 22 ohms. I set up to add water from in the house. when i am filling, i can hear and see gurgling and boiling water and stream coming of the vent tube. When it gets full the boiling stops, but next thing you know, the water level is down a noticeable amount. Within a few days its way down and have to add again.
Any ideas?

Central Boiler / Water heater water to water heat exchanger install
« on: November 02, 2016, 07:16:44 PM »
We have been using our system for four years with no problems at all. We do have the water to water heat exchanger installed on our water heater as per the Central boiler instructions as well as the installers instructions. The pilot light has been going out on the water heater for some reason. Why is it when the pilot light goes out, we have no hot water during the heating season? we do feel a difference in the water temperature being hotter when the system is up and running.
It is set up with the water heater side of the exchanger connecting to the output on the side of the water heater for the pressure relief valve and a tee extending out to re install the relief valve. The bottom end of the exchanger connects into the bottom of the water heater. On the boiler side, hot comes in to the top of the exchanger, then out the bottom of it and off to the furnace. The outside of the exchanger gets plenty hot.
How is water from the water heater forced though the exchanger, and out as needed? When the pilot is out, we don't get any hot water.
I would have thought you would put in a valve and cold water line to the input side of the exchanger and the output in the bottom of the water heater. With a shut off valve on the cold going into the water heater you can then shut if off and heat solely off the boiler heat exchanger.
Am I right?
