Install a Mini Water Heater DIY (#5251)
Did you ever turn on the hot water heater in the kitchen sink and it runs lukewarm for about 30 seconds? It’s because the water heater is located on the other side of the house.

But by installing an under the sink hot water heater, you can save water and still get hot water on demand.
