Why does my tankless water heater keep tripping?

The high resistance caused by a loose wire produces a substantial amount of heat that can eventually cause fires. If there is a loose electrical connection within your water heater’s system, your reset button’s thermometer can trip (regardless of the water’s temperature) if it picks up the heat from that loose wire.

People can end up with cold showers until that happens. With a tankless system, there isn’t a supply of hot water that can be depleted. Instead, the water heater heats up water as there is a demand for it. Although a tankless system can’t run out of hot water, it can still be overwhelmed with demand.

What happens when you turn off a tankless water heater?

Can a tankless water heater be used with a mini tank?

Note: If the temperature of hot water fluctuates during the shower, for example, it is recommended to combine your tankless with the “buffer” mini tank. The mini tank will always have hot water ready and deliver it to the shower before the tankless warms up. Shut off the cold water to the heater. Open all the hot water taps.
