Heat is good.

Boiler furnace would run but the Boiler pump would not heat the house, jumped power to the pump and it would run . Replaced aquastat board/box Works as advertised. Was impressed with Supply house delivery time.

Aquastat review

Brand spanking new out of the box failure! Found that the secondary of the transformer was not wave soldered! The one that I was replacing went bad after many years of service due to a cold solder joint! Great price for the unit, poor factory unit testing.

Direct replacement for my failed unit.

I can't say for sure how old the original was. It was here when we moved in 10 years ago; and the furnace was installed well before that…. So it was at least 10, and maybe 20 years old, if it was the original part. The replacement was exactly the same style as the old one; so there were no surprises installing/wiring it. Hint: Remember to turn the power off before installing.

It is likely an issue with the aquastat. It could also be a problem with the actual wires.

Both those items are obsolete and can be replaced by part L7224U1002. L8148A1090 can also be replaced by L8148A1017.

I am not a heating pro. I would compare the electrical rating on each unit and the layout- horizontal/ Vertical. My swap had different 4 digit end numbers in the id and the match was perfect mechanically and electrically. The part # L8148A were matching on both units.

If you are speaking of the insulation depth, the L8148 may be used with either the 1-1/2” or 3” model wells. These instructions are located on a label attached to the back of the control.

Q: I have the L8148A1017 on my boiler. The switching relay provides voltage to the boiler but not the circulator. Should I replace the whole thing or can I just change out the relay itself?

No, the last 4 digits do not matter. This would be an appropriate replacement.
