Filtered Instant Hot & Cold Water

In Sink Erator Model #HC1100. Maintains 1/2 Galloon of near boiling water up to 212 degrees. Cool tap water is plumbed into a valve in the dispensing faucet. When the valve is opened, the cool tap water flows into the tank displacing the near boiling water, which flows out of the faucet. The hot water dispenser can be less costly than heating water on a stove-top or microwave because the only water heated is that which is consumed.
