Customer Symptoms:

We received a call from a landlord who had been receiving complaints from a tenant who had no running hot water when she was using her bathroom sink.

Issue:

Before deciding what the best course of action would be, the technician needed to know if the water was ice cold or if it was lukewarm and not as hot as it had been in previous weeks.

Resolution:

The technician checked to make sure that the standby light on the tankless water heater was functioning so that he would know that the unit was receiving the power necessary to heat the water. The connections and the voltage to the water heater were also working, so the technician was able to rule out any electrical causes. After asking the landlord about the age of the water heater, the technician determined that the unit would need to be replaced as it was over 20 years old. He stressed the importance of regular maintenance checks to the new tankless water heater that would need to be purchased.
