So far, so good.
So far, the water heater is working fine. It was easy to install, with all the connections on the top. There two things I am less then thrilled about. The first is that you have to install a T so you can install the T and P valve. It has to be installed in the hot water outlet, as there is not a separate place for it. The second one is that the aquastat only has the 120 temperature setting marked. It doesn't keep the temperature as close as I would like. But I was installing a tempering valve anyway, so that wasn't a problem.

Ive had three of these. The first was installed when my house was new. The second was a replacement under warranty (the tank rusted out) and third was another replacment under warranty when the tank again rusted out. The second replacement was a total nightmare when the company demanded that I document the serial number of the original unit as well as the replacment. And of course there were several hundred dollars in charges for the work required to replace the units not covered by the warranty. The pros of the boiler mate is that it provides a pretty good hot water supply if you turn it up high enough so that you can mix cold water into it to fill a large bathtub. That magic number is about 160 degrees, which exceeds the perameters that the Boiler mate is designed to operate under. The cons are many. The first being is that your hot water supply is not separate from you heating system, so if you live in a climate where you ordinarily would be able to shut down your heating system for four or five months of warm weather, you cant. And if your boiler malfuctions, you also dont have any hot water. Second, This continual year round operation seems very hard on the boiler. In 19 years in this house I have had to not only replace the boiler mate twice, I have had to also replace the entire boiler once and have had it worked on for one issue or another related to almost continuous operation on average of every year and a half. It has been a very expensive lesson in the downsides of the Boiler mate. This week I have finally had enough. When the plumber gets out here Tuesday to repair thr boiler (again) we are going to decide on a new system independent from the boiler to replace it.

    My first BoilerMate lasted 33 years. Replaced it this past November. People seem to have mixed experiences. My new one (CH 41Z) is presently working as it should.

      I Purchased my first Boiler Mate 20 years ago. Why because at the time it had a lifetime Warranty. Well, my fifth unit just failed today. Yes, that is 5 units in 20 years. Free replacement but have to pay installation $400 to $900.
        Failed at year 8
        Mine failed and needs to be replaced after only 8 years. I have a filtration system on the water before it goes to this tank. Pitiful.
          Boilermate Failed after 3 Years
          Boilermate has a 6-year warranty but it is not transferable. We purchased home 3 months after the unit was installed and it failed after 3 years. No warranty coverage.

            This unit replaced an existing Amtrol water heater that we had for 21 years. It was still working fine but decided not to press our luck. Had to re- pipe because Amtrol changed all hook ups to come in the top. Pretty straight forward and the unit works great.
