Hi Folks, I run my hot water off off my oil fired boiler. I have plenty of heat but no hot water in the house. I suspect it's the circulation pump.
What type of things can I check to determine or fix the problem ?
Thanks Dick

Clarification please. Do you mean you have no domestic hot water but you have heat for the baseboard or radiators? If so, it is not the circulator as the house is not fed with a pump, just the heaters.
If you mean the boiler is firing, but not circulating to the baseboard, then yes, it may be the pump. Do you hear a relay clicking as you turn the thermostat on and off?
Assuming you have an indirect water maker, and not just a coil in the boiler: It will have an aquastat on it which is connected to a relay that turns on the circulator. Depending upon make and model, these things can be integral to the unit or placed on or near the boiler. Probably the easiest thing to do is turn the aquastat up, open the circulator wiring box and see if you have 120 volts on the circulator wires
Call someone who can see the installation.
Thanks, I have no domestic hot water but heat for the baseboard. The problem seemed to correct itself by turning the hot water temp to 130 but that was a couple of week ago and now I have the same problem.
I tried draining the bottom of the water tank. I did notice some darker water but now it's running clear.
Some info. It's a Super Stor Stainless Steel Indirect Fired Water Heater running from a Well McLain boiler.
I ran some hot water in the sink for about 3 minutes and it was lukewarm but still not hot.
Any suggestions ?
Thanks Dick
As I read this, your boiler is heating one side of this heat-exchanger, and is either controlled by a zone valve or a circ pump. So this circ pump, if there is one, could be the problem if it has failed; similarly with the zone valve. The literature says it has a lifetime warranty; I would call them and talk to them. Certainly they can make some suggestions
