I have a Toyotomi OM-180 that is being used as a boiler for

Hello,JA: Hello. How can we help?Customer: i have a Toyotomi OM-180 that is being used as a boiler for baseboard heat. There is a pump in the system for circulating the hot water that is wired to run all the time. The temp on the unit is set at 130*. The wall thermostat is set at 65*. The unit fires up, runs for about 22 seconds, then shuts down. It starts back up again a few minutes later, and runs for 22 seconds again. It does this non-stop, never running for more than 22 seconds. The temp at the wall thermostat never gets up to 65*. It's like the heat system can't keep up with the outside temperature, but the unit is cycling off. The temp gauge on the outlet side of the unit shows 130*. The inlet fitting seems to be the same temp by touch, though the is no gauge there. The piping to all the baseboard radiators feels warm, as do the radiators. This house is new to me. I am told that this is how the system has always been whenever it gets below about 30* outside; that the unit cannot keep the house warm. Seems to me that if the unit itself is getting up to temp and cycling off, then there is excess heat available that is somehow not getting into the house. Ideas?JA: Did you double-check the thermostat's settings? And what about the filters?Customer: You mean the wall thermostat? Or the one on the unit? Which filters? Air? Fuel? Not sure where the air filter is, if there is one.JA: Do you plan on doing the work yourself?Customer: Yes, as I'm in a remote area of Alaska and d't have another option. I am an aircraft mechanic, but with limited knowledge of HVAC.JA: Anything else we should know to help you best?Customer: I think that's it for now.

Gas Furnace, replaced item on top of expansion tank with the

Gas Furnace, replaced item on top of expansion tank with the air valve that releases air for the expansion tank. water was spraying out from top for expansion valve. Afterward water was coming from the overflow tube daily. So I took about 3 gallons of water from overflow tube. The water stopped dripping. At night you can hear water running through baseboards that keeping you from sleeping. The house has two zone heating. The gauge on the furnace is at 20 lbs. Can you please help me.

17 year old CG boiler. Worked good until now. Keep getting

17 year old CG boiler. Worked good until now. Keep getting air in the system so it doesn't put out proper heat to the house. Service tech power bled all zones and put on a new auto vent on top of the expansion tank manifold. The furnace cycles on and off like it should.JA: Did you double-check the thermostat's settings? And what about the filters?Customer: gas fired boiler. I don't know of any filter. Thermostat is set to 80 but the best it will do is get it up to 66 degrees in the house.JA: Do you plan on doing the work yourself?Customer: I've had service guys to house 4 times. And they are reputable and good but can't seem to find the answer why it keeps getting air. We've discussed maybe the seal is leaking in the circulating pump. Is that a possibility ?JA: Anything else we should know to help you best?Customer: This system is 58 years old. Meaning registers and piping. Furnace is 17 years old and never a problem with air getting into the system until a couple of months ago. Complete service was done to the furnace on the first service call trying to figure out the problem. And the expansion tank was replaced last year and seems to be ok. Hot on the top half and cold on the bottom half.
