Has anyone ever used the SharkBite Tank Booster or a product like it?
I was looking to increase the hot water capacity at my house, and was shown this:
The basic idea is that instead of just storing 120 degree water in your hot water tank and using it until it is empty, you change your water tank to store water at 140 degrees. When you require hot water, a valve mixes the 140 degree water with a little cold water to put it back down to 120 degrees. This way, you get to use more 120 degree water than you could if you used it straight up.
Has anyone ever messed with this? Or can you suggest an alternative? Someone suggested running two hot water tanks in series ...
