Leridian Dynamics, Inc. is proud to announce the release of the Smart Thermostatic Control. After years of testing to figure out a solution for homes that do not have a dedicated hot water recirculation loop, we have finally found a thermostatic crossover valve that has high enough flow to provide "on demand" comfort. The high quality AquaMotion AMK-ODR brass and stainless thermostatic crossover valve is designed to allow high flow in order for tankless water heaters to activate. It is this high level of flow that allows "on demand" comfort. The smaller plastic valves from Grundfos/Watts/Taco just don't allow high enough flow to allow the hot water line to heat up quickly enough. This is also the reason they do not work with tankless water heaters.
The AquaMotion AMK-ODR valve will work with both tankless and tank water heaters. Our control for a tank system comes with a thermostat to ensure the water coming out of the tank is greater than 95F, the temperature required to close the AquaMotion AMK-ODR valve, which prevents lukewarm water from being recirculated throughout the home. Since tankless water heaters never run out of hot water they don't require this extra check, but if you purchase a tank controller and later install a tankless, it is not a problem as the system will still work.
And as with all our products, there is a 2 year warranty and 90 day satisfaction guarantee.
