We love this whole set-up, but the tank on the heater is made of some sort of poor material and starts leaking about every 5-6 years. This is our third water heater and we love it while it works. It does seem to us that the manufacturer could make the tank out of some material that would not break down so quickly. After all, our general household water heater was just replaced after 35 years of service without a leak and it worked well the whole time. Our plumber says that these products used to last for 25-30 years when first introduced, but that now they fail rather regularly. The faucet has failed after about 18 years, so it is better than the heater tank, though why it should start balking and not closing consistently is a mystery.
