How does cold water affect a hot water heater?
These colder temperatures cool down the water that enters your hot water heater, and in effect, your hot water heater has to work harder to heat the chilly water to the right temperature. As your hot water heater is working to heat up the water, cold water enters the unit, thereby cooling the water back down.
What causes a tankless water heater to go cold?
Think of it as “on-demand” hot water– it’s only there when you need it. When you turn the hot water tap, your tankless system’s flame ignites the heat exchanger. Then, cold water enters an inlet pipe at the bottom of your water heater. As the water flows through the unit, it preheats by way of any escaping or “secondary” heat.
Why is my hot water heater not working?
