SITUATION: 50 year old boiler running classic radiators on 100 year old house (converted into 8 apartments).
Boiler and pump kick in for 30 – 100 seconds then turn off. Boiler pressure appears between 18 and 20. Temperature is well below 70 degrees.
When I first turned on the boiler, it kicked on and ran continuous til temp was attained and then cycled on and off. The temperature of the house was in the 50s when I started the boiler on Nov 1. Last year it appeared to be the same problem, but eventually the boiler gets hot enuff and heats appropriately (but with far too many cycles from my perspective). The system seemed to work best during the dead of winter when the boiler did not shut down for extended time during the day.
I have replaced no parts and the controls are without LEDS or schematics or troubleshooting information.
Could somebody point out what I should be looking into, I would like to be able to maintain the system myself and purchase appropriate replacement parts as needed.
Is there somewhere I can look to learn about the switched/sensors on the outlet and return piping and any other sensors as needed.
I am going to start by replacing the thermostat and go from there.
Is there some way to put a relay in front of the pump to delay its running for 1-2 minutes after the boiler ignites?
