This is gonna be one of those posts with way too many photos, but not because it’s one of my random collections of Fun Friday Photos.With this one I hope to assist anyone who may need help to troubleshoot and fix RV water heater issues.Specifically, I’ll show how to repair an RV water heater that no longer heats water.

Unlike traditional water heaters, the hot water supply is not stored in the tank. In this article, we will explore how tankless water heaters work, from gas and electric tankless heaters to whole home and point of use models. The immersion heater itself sits inside a hot water cylinder and is powered by a strong electric current. Hot water tanks, or cylinders, are a way of storing your hot water and keeping it warm for when you need it. Electric water heaters have a separate thermostat, while the thermostat on gas models is built into the gas control valve. The idea behind a tankless system is that it heats the water as you need it instead of continually heating water stored in a tank. As a result, tankless water heaters deliver a constant supply of hot water. Always disconnect the power and then drain the water from the tank before attempting to remove the heating elements.

The differences between electric and gas water heater types are more apparent when you get down to the basics of operation. It is positioned in the pilot flame and sends a signal to the gas valve to keep it open whenever the pilot is lit. Some of the typical problems that occur are common to both types, but other issues are unique to electric water heaters. The heating element is in turn submerged in the water of the tank and heats up in the same way that an electric stove burner works, by passing electricity through a resistant material and converting energy into heat. This serves as a protective layer and can hold about 40 up to 60 gallons of boiling hot water at about 50 up to 100 PSI. Some water heaters use a hot water recirculating system which keeps hot water moving through the heating system and prevents hot water flow from being interrupted with “cold” spurts of unheated water. Instead, hot water is created through heat transfer using the home’s boiler or furnace. When the water temperature in the tank falls, the thermostat sends a signal to the gas control valve, which checks the signal from the thermocouple to ascertain that there is a pilot light. Wiring an electric water heater involves several electrical components. 1. Sometimes water will shoot out of the valve on the side of the tank. Then the upper element would rarely turn on.
