The Cooperative sells the Marathon Water Heater, which is warranted not to leak as long as you own your home. Rebates are available for current members of the Cooperative. The rebate on a 50 gallon model is $250. The rebate on the 85 gallon is $300 and 105 gallon model is $350 and the Hybrid Heat Pump is $500. I have attached some information on the Marathon water heaters and also an advertisement that you may want to use. Call for prices and after the purchase of a Marathon Water Heater please register your water heater at for warranty purposes.
