Re: Boiler on the fritz?

180 is not low. There are many things that can be causing your problem.

1-air in system
2-bad circulator
3-zone valve if you have more than one zone
4-electrical problem (thermostat,relay transformer)

Re: Boiler on the fritz?

Thanks John.

1. I do not believe there is air in the system, but I will go around and open the air release valves. It has been fine for the past month or so.

2. My circulator pump appears to be pumping. Water is hot at the beginning and end of the line (just not AS hot as it once was) and I do not hear anything different from what it has always sounded like. But since I have never messed with it, I would guess this is the closest of any of your other possibilities.

3. The zone valves are manual twist valves. I have never touched them. Could sediment be blocking them?

4. How might an electrical problem show itself? I know I can start up the boiler and pump and shut it off at will from the thermostat.

Does any of this additional information help narrow down the issue?

Re: Boiler on the fritz?

If your water heater is doing the same thing it sounds like the pressure regulator on the meter was damaged in the move. Don't waste any time getting that looked at.

Re the circ. pump. Often the sound of the gas burner drowns out the sound of the circ. pump so it's hard to tell if it's running. Here's an old mechanic's trick: Take a long screwdriver and press the metal end against the pump flange and press the plastic handle against your ear. The sound of the pump running should then be obvious.

Thanks.

Guy - If I'm ever in Romeo you will have to show me that trick. Evidence is pointing to a bad circulator pump, but I would like to rule out everything else before I put one on order. The current model is a Bell and Gossett series 100, 1/12th HP.

The gas company will be out on Thursday to check the gas pressure.

One outlet from the boiler is skin-singeing hot. I follow it 30 feet in the basement until I reach where it goes up and it becomes luke-warm. It will still put out heat at the baseboards, but the house won't get up over 61, and the boiler has to run constantly. I have it turned off until this problem is fixed.

I don't see any other evidence of a bad circulator pump -- no leaking, no unusually loud noises. Pump appears to be pumping. Could these slowly decline and that is what I am seeing?

Can anyone speak to the electrical components of the boiler and if perhaps there could be an issue there?

Thanks!

Re: Boiler on the fritz?

On the type pump you have there is a spring coupling between the pump and motor that you can see spinning if it's running.

Re: Boiler on the fritz?

It looks like there are a few parts inside the pump spinning, so perhaps the pump is not the issue?

I'm stumped. Perhaps time for the experts to have a look. My last attempt will be to recharge the system -- maybe buildup somewhere is restricting flow or air? It just blows my mind, the pipes are scalding all through the system, but the house doesn't get hot. Like someone went through and stole all my aluminum fins.

Re: Boiler on the fritz?

Are the lines hot at all of the baseboards? If so then you have may have a problem with the design of the system. (Not enough baseboard) If the lines at the baseboard are not hot your problem is air.

Re: Boiler on the fritz?

If all the pipes are warm--but not as hot as they used to be--then I still think the problem is the high gas pressure. That can cause the flame to lift off the burners and is terrible efficiency.

Let us know what the gas man says when he visits today.

Re: Boiler on the fritz?

Guy - gas company just came out and tested pressure. 4oz indoors and 5oz at the meter, which he said was normal. Next step is getting the boiler serviced. Looks like earliest available is Monday.
