I would purchase this product again

Product work in my first attempt. I am an accountant and if I can install this product i think most of the people would not have problem.

Most Liked Negative Review

It works but it's noisy.

The old unit on my furnace stopped initiating the burner flame. This unit solved that problem with easy, straight forward installation instructions. However, the relay chatters during the heating cycle. If this shortens the life of the unit, it's a loser. And the chatter has become background noise when I'm in hearing range.

Excellent support

Originally purchased the wrong aquastat, but support worked with me to get the correct unit and provided free return shipping of the wrong part. Really helped sort out a confusing mess of which part to use in a friendly and communicative manner. Will definitely use SupplyHouse for future parts needs!

The L8148E1265 AND L8148E1257 are the same control, however their temperature ranges are different. The L8148E1257 has a temperature range of 140-240 degrees F, while the L8148E1265 has a temperature range of 180-240 degrees F. They are both Aquastats used with a vent damper. Either control would be appropriate to use.

The L8148E1265 is used on gas and only if you are using a vent damper. If this meets your requirements, you can use this item as a replacement. However, if you are not using a vent damper, the L8148J1009 should be the part used.

In order to get an accurate replacement you will need to find out the full model number of the aquastat you are replacing. Usually if a model is obsolete it will have a suggested replacement. Aquastats are also selected based on desired temperature range and differential.
