                      This fits right where the other Aquastat went. Just loosen the set screw in the back and disconnect the wires and just reverse the process to install. I also installed it vertical even though it says horizontal.

                            This aquastat is the correct control for my home heating system. There has been one minor revision of this model since the last one was installed in 2008. But, it is the height of 1950's technology and is still comparable to the original model.

                            It is a well built simple design. It was easy to install. It is easy to adjust so that my heating system is functioning within its designed temperature range.

                            I would buy another if needed and I would buy it here. Pexsupply processed and shipped my order quickly.

                                              I will give Pex Supply an a+ on this product. Easy hookup directions where easily understood. Local plumber was 2.5 times the price so the time it took for shipping was well worth the wait. Again A+ Thanks

                                                    They had exactly what I needed. I was not looking to adapt a "similar product" to my heating system, I wanted to remove and replace. This was an exact match, half-hour job going carefully and deliberately, and my system was back to fully operational. No complaints, very happy.

                                                                Replacing my old broken honeywell L8148A 1090 aquastat relay with this part took just a few minutes, and everything worked as expected. If you are a handyman, contractor, engineer, or retired scientist, who is used to working on electrical systems, heating systems and so on, you will be satisfied with this part. If you don't know what a volt meter is, you should probably get a handyman to spend a few minutes installing and testing this part for you, cause you don't want to get electrocuted or create a huge and potentially dangerous problem with your heating system. If you want some specific advice from an electrician or HVAC contractor, consider using www.justanswer.com . It is a fast and cost effective service.

This means the furnace starts back up after the water cools just 8 degrees. This seems like a big waste of hot water that could be heater my water tank, why not have a larger differential like 15 degrees ? Water only gets heated to 120 * I realize the higher the furnace temp water is the quicker the water tank will recover but what if I don't need a quick recover. I also realise that the heating of the house may suffer alittle with a larger differential but thats OK also. Is ther another Aquastat relay that mounts horizontal that has a little larger derrerential temp. ? The L8148A 1017 has a non adj. differebtial temp.
                                                                  What I'm trying to do is burn less oil while heating up the water tank during the summer months when heating the house is not needed.

You can use the L7224U and in the installer setup turn the low limit to "Off" for a cold start application. The parameters for low voltage is 20Vac to 30Vac. A surge in voltage can cause a problem if the voltage is running as high as 30Vac and you go over the recommended voltage, so you should check to make sure this is a good fit.

                                                                    I believe most, but not all boilers have their temp elements mounted in a well.
                                                                    Hope this helps...

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.
