Taco Pumps

We utilize Taco pumps on all our commercial systems. Each is a 1/2 hp hydronic circulation pump. One is used to supply water up to the solar field and the other to supply the ODW heaters. The water is always returned back to the top of the storage tank.

Grundfos Pumps

On the residential mini and maxi, we utilize 2 Grundfos UP-15 hydronic pumps in a series to supply the solar field when solar contribution is available.

When solar is not available, a diverting valve sends the water to the ODW heater and returns the hot water back to the top of the tank.
