Shower water temperature fluctuation to extreme

by Bob
(Upstate New York)

We recently installed a tankless electric water heater in our ranch home and are really dissatisfied. The shower water, which is close to the heater is hot then cold and cannot be regulated. It is frustrating and my people are hesitant to shower. This could be a problem!!! I paid about $1,300 for heater and installation all to get away from domestic hot water from the oil fired furnace running all year. I would love to know what, if anything, can be done about this.

Hi Bob,
I understand your problem, spending so much money and have the weak results.

I will try to help you in troubleshooting your tankless water heater. Actually I have an article about this problem, so I would suggest you to take a look and see does it help you in fixing the temperature fluctuation problem.

Find below what this article covers:

- Hot water temperature fluctuation due to the low water pressure.

- Temperature fluctuation due to the water flow restriction.

- Temperature fluctuates due to the dirty filter screen.

- Water temperature fluctuation due to the plumbing crossover.

- Recommended water pressure.

- Mixing valve as the cause for sudden water temperature change.

What to do when water temperature fluctuates.
