Best Temp Setting For Hot Water Boilers Aquastat

If the aquastat does not agree with the temperature gauge. As the burner re-heats the boiler and the boiler temperature rises back up to 120 the burner turns off and the circulator is allowed to turn on. I just put a new temperature gauge on front of my boiler and for an Aquastat setting of 180 for high the gauge temp goes up to 220I set the aquastat to 160 low and high temp reaches 200So its about 40 degrees off. If your aquastat HI limit is set to 200 F about as high as is safe as long as the boiler temp stays above about 180F the burner wont come on until boiler water drops below that point. Aquastat is set to 190. The cutoff temperature for most hot water boilers is 180 F. Sometimes the boiler high limit is set higher to get more heat faster out of the baseboard especially when there isnt enough of it.

I have a hydronic heating system- mostly cast iron radiators and a couple cast iron baseboards and 3 copper fin baseboards.

LO 120 F DIFF 10 F. Water this hot must be. At 150 it wont run as long in the summer because the boiler maintains that setting but in the winter it runs above 150 normally and it just takes longer to heat up the house. The more I read it seems the DHW works off the low limits side anyway so it may not be a concern. In most cases the high-limit temperature setting on an aquastat should be between 180 and 200 degrees Fahrenheit. If the aquastat is set at 200 degrees Fahrenheit as the high-limit setting and the pressure valve begins to leak set the temperature back to 195 degrees Fahrenheit.

Best temp setting for hot water boilers aquastat. The cutoff temperature for most hot water boilers is 180 F. Recommended Temperature Settings Water heaters are factory set at OSHA recommended levels around 140 degrees. Can this possibly an issue with my programmable thermostat.

The boiler Cut-on temperature or burner turn-on temperature for the boiler AS LONG AS THE THERMOSTAT IS CALLING FOR HEAT is fixed at 10 degF. Water this hot must be. For example an aquastat is often set to maintain a boiler water temperature of anywhere from 180 to 200 degrees in the winter.

With cast iron rads some people keep it at 150. To maximise efficiency we recommend setting your radiator dial to 75 degrees and your hot water to 60 degrees. Here in Maine with a degree day load of 7500 its not uncommon to see the high at 200 and the low at 180.

If the aquastat does not agree with the temperature gauge. If your aquastat HI limit is set to 200 F about as high as is safe as long as the boiler temp stays above about 180F the burner wont come on until boiler water drops below that point. Click to see full answer.

The fact that it is a triple aquastat yet the DHW is capped off led me to wonder if the settings were ever adjusted properly to compensate for the absence of hot water demand. Aquastat is set to 190. The HI on a combination heating control like this aquastat is usually set by the heating service technician to a spot between 180 F and 200 F.

The only way he can tell if theres calcium in. Most boilers are set for 160180 for baseboard or 150170 with cast iron rads. It is often a trial error thing.

They BOTH are inaccurate. As the burner re-heats the boiler and the boiler temperature rises back up to 120 the burner turns off and the circulator is allowed to turn on.

Water temps only get to 150 before the boiler shuts off.

On some controls this hard-wired fixed gap may be 15 F. With cast iron rads some people keep it at 150. If your aquastat HI limit is set to 200 F about as high as is safe as long as the boiler temp stays above about 180F the burner wont come on until boiler water drops below that point. Water this hot must be. The aquastat is a Honeywell L8124C and probably about 15 to 20 years old. Sometimes the boiler high limit is set higher to get more heat faster out of the baseboard especially when there isnt enough of it. Here in Maine with a degree day load of 7500 its not uncommon to see the high at 200 and the low at 180. The HI on a combination heating control like this aquastat is usually set by the heating service technician to a spot between 180 F and 200 F. On the other hand the EPA suggests turning the thermostat down to 120 to reduce power consumption and a booster heater to reach sanitizing temperatures at.

Normally for boiler efficiency we like to set the aquastat HI to 200. As the burner re-heats the boiler and the boiler temperature rises back up to 120 the burner turns off and the circulator is allowed to turn on. I have a hydronic heating system- mostly cast iron radiators and a couple cast iron baseboards and 3 copper fin baseboards. In the summer you can reduce the low limit to 140 for hot water. Radiators throw heat but the baseboards need hotter water to be effective IMO. The aquastat is a Honeywell L8124C and probably about 15 to 20 years old. Normally for boiler efficiency we like to set the aquastat HI to 200.
