I have an American Standard boiler that dates to ~1973. The unit appears to work fine but it comes on very frequently. The temperature limit control (made by Honeywell) is set at 180 degrees (which causes the frequent shutdown and startup). The limit control will not turn past 180 degrees (even though there are higher temperatures visible on the adjustment knob). The manual recommends a temperature limit setting of 220 or below.
Q1. Will this frequent shutoff and startup influence boiler efficiency and overall cost of heating? If so, would there be an advantage to purchasing a different temperature limit control and set it at 220 F? Where can I go to find parts for a 28 year old American Standard boiler?
Q3. The sheet metal panels that surround the boiler sections grow very hot in a few select places. Is this a cause for concern? Can I simply stuff some fiberglass insulation between the panels and the outer boiler sections?
Thanks!
