What is Reddit's opinion of Laing LHB08100092 AutoCirc Recirculation Pump with Timer?

From 3.5 billion Reddit comments

Definitely go for it - I have a boiler with an indirect hot water tank (so the water is heated via a heat exchanger coil from the boiler) - that was a good upgrade because it’s similar to a tankless HWH as far as being able to keep up real time while at the same time keeping hot water in reserve. (My tank is a Burnham Alliance SL50.)

That being said - my house is old and it takes several/many minutes for hot water to arrive at my furthest bathroom. Even without automation, knowing that I can recirc to get hot water to the fixtures rather than just running all that water down the drain is better overall and when I leave it on - I know I’m probably incurring some energy costs but I haven’t noticed any change in my gas bill, but it is totally worth it for immediate hot water at the tap.

Not an endorsement but this is the one I have because it doesn’t require a separate recirculating line since I was retrofitting and couldn’t install a separate loop.

It's a recirculating pump with a timer. It's so you don't have to wait for hot water nearly as long. It cycles periodically to keep the water in the hot water lines hot. Typically put in bathrooms far away from the water heater so you don't have to wait minutes for your shower to get hot.

Looks like you have something very similar to this model: https://www.amazon.com/Laing-LHB08100092-AutoCirc-Recirculation-Timer/dp/B0046MDAK0

No that is a recirculation valve, not a mixing valve. It's there to you don't have to wait forever for hot water. They're typically placed on faucets in bathrooms far away from the water heater.
