It should be hooked up to your existing hot water tank.    Dan

If I hook it up to the water heater, will the heater have to stay on full time? At present I only switch on the water heater only before using hot water for shower. Just don't understand how the hot water will circulate so it's always hot from solar system. Thanks, Les

Les our systems come with a differential controller and a pump which controls this.  If you can load the hot water tank with solar then you will not have to tun on the hot water element to take a shower.  In the evening the solar pump is shut off.     Here is the system you will need which comes with everything to hook into your existing hot water heater. Retrofit Solar Water Heater   On this page you will see the diagram of how it works.   Dan
