I have this unit on my Geo Thermal Unit. It works great. I run my unit on well water (open loop) and heat and cool year round. These units last about 8-10 years in the Attic were ambient temperatures vary from -10F to 150F.

I use this valve on an open system heat pump. It works great for the first 12 to 18 months then the end switch quits working. Either the end switch contacts go bad or the power mechanism starts getting weak with age. The end switch circuit drops out the compressor circuit and the fan keeps running which cancels out most of the benefit of the heat pump. After the compressor circuit times out the compressor restarts again until either the thermostat is satisfied or the end switch malfunctions again. Very aggravating. I use a single pole switch in parallel with the end switch and manually do the end switches job until I reorder and replace another Power Unit. I'm now on my fourth Power Unit.

Power Unit for Taco 5101-G2 Valve
By Bob the Builder
Comments about Power Unit for 5101-G2:
First the good: When the unit goes bad, you can twist it off and twist on the replacement, then hook up the wires and you're back in businessThe bad: The power unit appears to have about a 3-4 year life expectancy. The heater wires in the head are poorly connected to the power feed and the connections eventually fail.With that in mind, if you have a Taco 5101-G2 valve, buy an extra powerhead to keep on the shelf for when the one in service goes bad. It will be less costly to replace it yourself than paying a technician $250 or more for a service call.

Taco Power Unit
from Oxford, New Jersey
I bought this product as to have a spare power head. I haven't used it as yet. But it was delivered extremely fast, within three days. Very happy with the speed that it was processed. I purchased this product in the past and it worked flawlessly for quite a few years.
Not up to the job!!
By Dangerous Dan
from Simsbury, Ct.
I also have an open loop supply feeding a Water Furnace. The weak link in this valve head is the contact points that control the current to the heater. They quickly burn up from constantly arcing. I have been thru 5 valve heads in 5 years. If you drill out the POP rivet and dis-assemble the valve you will find the points are totally gone!
Taco Power Head Doesn't Last Long
from Moose Lake, MN
This Taco Power Head on my Ground Source Heat Pump was installed 5 years ago. I'm now on my 3rd head in five years, averaging about 2 years between failures. My water is not excessively hard or dirty. The valve head works great until it doesn't. It seems to me that it should last a lot longer than two years. Therefore, I cannot recommend it.
Good thing I checked online
from Wabash IN
My local supply company charges much more.

On open loop geothermal. These last me about a year. that's it. I just switched to the electric motor actuated ball valve from Taco. Hopefully it lasts longer.
