Boiler Heat- The lower the setting the better?

Question

I know that the temp for the boiler on my home heating system is suggested to be between 120 and 240 but I noticed it is normally from 90-100 degrees. Is that less efficient? Should it be higher? I want it to be the most efficient and don't really care about how long it takes to work. It seems to run every 3-5 minutes but only for short burst of time and it just seems to me to be using a lot of fuel- although my house is an OLD farmhouse. Should I adjust that setting? Is there an easy way I can change that setting? It is a Slant/Fin Sentinel S210-EDM (I think those are the letters/numbers). Any suggestions?

Answer 1

The first thing I'd check would be to see if that's the temperature at rest, when the burner and the circulator motor are both off. Depending on how your controls are wired, if you're reading between 90 and 100 degrees when the burner is on and the circulator pump is running, I'd question the accuracy of the thermometer on your boiler. 90 degrees is not even lukewarm, so I don't see how that could possibly be the maximum temperature your boiler water reaches. If you have any exposed heating pipes, try taping a quick reading kitchen thermometer to one of the exposed pipes on a spot close to the furnace, and see what that thermometer reads during the cycling of your furnace....As to setting the water temperature is concerned, there may be two "aquastats" that monitor the boiler water temperature. One might be set to 180 degrees or so, that should be the high temperature cut-off. There should be one that is set somewhere between 120 and 180 or so. That's the one that would control the burner mechanism to maintain the operating temperature of your boiler....Let me know if I've helped at all, Thanks.

you're very, very not likely to wade through a freeze-up on your sources. We continually turn the water off and the gas besides. i have been primary to depart a fan heater sat interior the midst of the floor at a low thermostat putting, "only in case", in particularly extreme (for the united kingdom) climate. The electricity continues to be on to skill various lighting fixtures fixtures biking on and stale for safe practices applications besides.
