You choose a
tankless water heater because of its convenience, but just like any other
system, it can also malfunction. Have you had problems where your heater works
properly but fails minutes later? If so, here's all you need to know about why your tankless water heater
goes cold and what you can do about it.
Cold Water Switch
You must have
experienced the notorious cold water switch when the heater is used after being
turned off for a while. The water inside the system starts running out cold, so
when it mixes with the heated water, the water flowing out is unusually colder
than expected. As a result, you deal with water that is inconsistently hot and
cold. To solve this problem, you can either use a recirculation device or,
alternatively, let the cold water run out for a minute before using it.
Sediment and Dirt Build Up in
the Filter
Are you wondering why your tankless water heater
goes from hot to cold in a short time? It may be because your filter is
dirty. The more you use the unit, the more sediment builds up, clogging the
system, reducing the water pressure, and making it work extra hard. This forces
it to keep recycling on and off, causing temperature inconsistencies. It helps
to frequently check the filters and conduct proper care and maintenance, calling
for replacements when necessary.
Flow Sensor Issues
Another logical
explanation for why your
tankless water heater goes cold is because of issues with the flow
sensor. This gadget monitors the water flow and activates the heating. However,
if the readings are faulty, the system will either overheat or fail to heat.
When you call in the experts, they clean the sensor and check whether the flow
rate is accurately detected. They also adjust the wiring, making sure that it
is connected properly.
Issues With Gas Line Size
When you opt for a tankless water heater,
experts ensure that the gas line is the perfect size for the unit. Otherwise,
it will fail to deliver the water you need, especially during peak hours. The
best way to handle this is to install the proper gas line size according to the
product's manual or use a temporary booster.
