Are 120v tankless water heaters affected by water hammer in an RV?

As a supplier of 120v Tankless Water Heaters for RVs, I've encountered numerous questions regarding the performance and durability of our products in various scenarios. One of the most common concerns is whether these 120v tankless water heaters are affected by water hammer in an RV environment. In this blog, we'll delve into the science behind water hammer, its potential impact on 120v tankless water heaters in RVs, and how to mitigate these risks.

Understanding Water Hammer

Water hammer is a hydraulic shock that occurs when the flow of water in a plumbing system is suddenly stopped or changed direction. This rapid change in flow can create a pressure wave that travels through the pipes, causing a loud "hammering" noise. The main causes of water hammer include quickly closing a valve, such as a faucet or a toilet flush valve, or a sudden stop in the water pump operation.

In an RV, the plumbing system is typically more compact and may have different pipe materials and configurations compared to a traditional home plumbing system. This can make the effects of water hammer more pronounced and potentially more damaging to the components of the plumbing system, including the 120v tankless water heater.

How Water Hammer Affects 120v Tankless Water Heaters in RVs

The internal components of a 120v tankless water heater are designed to handle a certain range of water pressure and flow rates. When water hammer occurs, the sudden increase in pressure can exceed these design limits, leading to several potential issues:

Damage to Heater Elements: The heating elements in a 120v tankless water heater are sensitive to pressure changes. A sudden spike in pressure can cause the heating elements to crack or break, leading to a decrease in heating efficiency or even complete failure of the heater.
Leaking Seals and Gaskets: The seals and gaskets in the water heater are responsible for preventing water leakage. Water hammer can cause these seals and gaskets to loosen or fail, resulting in water leaks. This not only wastes water but can also damage the surrounding components in the RV.
Malfunction of Sensors and Controls: Modern 120v tankless water heaters are equipped with various sensors and controls to monitor and regulate the water temperature and flow rate. The pressure wave from water hammer can disrupt the operation of these sensors and controls, leading to inaccurate temperature readings or improper functioning of the heater.

Identifying Signs of Water Hammer in an RV

If you suspect that your RV's 120v tankless water heater is being affected by water hammer, there are several signs to look out for:

CE Certificate Tankless Water Heater

Loud Banging Noises: The most obvious sign of water hammer is a loud banging or hammering noise in the pipes when a valve is closed or the water pump stops. This noise can be quite startling and may indicate a significant pressure wave in the plumbing system.
Water Leaks: Check for any signs of water leakage around the water heater or other plumbing fixtures. A leaky seal or gasket due to water hammer can cause water to drip or pool in the area.
Inconsistent Water Temperature: If you notice that the water temperature from your tankless water heater is inconsistent or fluctuating more than usual, it could be a sign that the sensors or controls have been affected by water hammer.

Mitigating the Effects of Water Hammer

Fortunately, there are several steps you can take to reduce the risk of water hammer and protect your 120v tankless water heater in your RV:

Install a Water Hammer Arrestor: A water hammer arrestor is a device that absorbs the pressure wave created by water hammer, preventing it from traveling through the pipes and causing damage to the water heater and other plumbing components. These devices are relatively inexpensive and easy to install.
Slow-Closing Valves: Consider replacing any fast-closing valves in your RV's plumbing system with slow-closing valves. Slow-closing valves gradually reduce the water flow, minimizing the sudden change in pressure that can cause water hammer.
Proper Plumbing Installation: Ensure that your RV's plumbing system is installed correctly, with proper pipe supports and adequate clearances. This can help reduce the vibration and movement of the pipes, which can contribute to water hammer.
