To begin with this looks like a great place to get my question answered. I am a State Certified Plumbing Contractor in Florida and have no experience in electrical circuits. I can do the electrical work in a house with some advice and actually wired most of my current home.
What i need to purchase or build. I am trying to use a tanked hot water heater as the primary "tanked" and a "tankless" electric as a secondary. I have my electric tanked heater on a timer. I want to put a "tankless" one after the tanked one in line with the plumbing. I want a relay or something that keeps the secondary "tankless" off when ever the timer has the primary "tanked" heater engaged. But when the timer has the primary "tanked" turned off, I want the secondary "tankless" to be online; then turn off when timer rengages the primary "tanked". The primary "tanked" draws 27 amps when on but the secondary "tankless" draws 74 amps when fully on and comes on almost at once to full power if all elements engage. This is a 220/240 volt system.
I sure would be grateful if you could direct me to where I could buy one or if someone could email me a circuit. I know someone who could help me make it. Thanks for your time. I would be glad to respond to any plumbing questions you may have by email. I hope I posted this on the right forum thread.
