These systems are NOT FOR TANKLESS hot water systems.Read some negative review from people who installed on a tankless hot water.These hot water recirc systems are made to bring hot water from a main hot water tank and ensure that hot water 96-104 degrees F from main water tank is maintained at all distant hot water outlets, sinks, showers and tubs. The temp sensitive check valve should be installed on the hot water outlet farthest from the hot water tank

Our kitchen tap is a long ways from the water heater and had to run the water quite awhile to get hot water. With this plus a circulation pump we now have instantaneous hot water.

Funciona y hace lo que promete, cuando se enfría abre la valvula y se mezcla para realizar la recirculacion, hay que considerar que enciende más veces el presurizador y el boiler

I installed two of these in a house with a long line to the bathroom and a fairly long one to the kitchen sink. Both work fine with the Grundfos pump I used. I had earlier tried a different pump that came with plastic mixing valves like this and it was clear they were quite fragile so I prefer these. However one kept leaking. I tighten the fittings and added more teflon tape but it still leaked. I finally saw that the water was coming from the union in the valve itself. I was able to unscrew it without damage—carefully—and applied some nylok to the threads, solving the problem. I could see they’d used a little dab of some similar sealant at the factory, but not enough. Other than that I fully recommend these things.

The flow via the recirculation is about 2 to 3 time more than the plastic valve kit I had before. When the water in the hot water line is hot enough the valve positively closes without leakage to bypass, thus improving the hot water pressure at the faucet.

Great product and works as advertised. Like the hotter 104F cutoff versus Watts. I've only had it for a few days but it seems like it should last as I've had to replace several Watts recirculating bypass valves already after three months. Would recommend but hope it last years like it should.
