Why Does My Tankless Water Heater Go Cold

The Outside Temperature Is Nosediving

One of the likely possibilities for a cold tankless heater is the cold external temperatures. This might seem painfully obvious, especially if you live in a colder climate, but you’d be surprised to know how many people don’t even consider the fact that the outside temperature is affecting the water temperature in their tankless heater. If this is happening, you’re simply going to have to wait until the temperatures get back to a normal level. Because simply put, they are not going to improve just because you want them to. It’s going to take a considerable level of patience on your end to see any really significant changes, but if you’re patient, you’ll get that warm water again.

There is a Disconnect From the Power Connector

One of the primary ways that a tankless heater creates heat is by the vibrations in the electric coils. However, for this to work, you need a steady power connection, otherwise, it’s simply not going to work. While a lot of people simply give up at this point, it’s important to acknowledge that there is absolutely no need to give up on your heater just because it’s not heating properly. You can go a long way to properly invest in the necessary equipment that makes the heater work, and if it does, you’ll notice very quickly that the coils are recalibrating, ensuring that the proper electrical connection established. This is absolutely vital to make sure the connection works, otherwise, you’re going to see long-term damage from start to finish.
