When Water Heaters Don't...

Computer User
When I worked in aerospace, much of my time was spent helping computer users and designing reporting tools so those companies could get the best value from their software systems.

We often joked (privately of course) that most of the issues users face are really simple. Like the computer not being plugged in or worse, turned on. We had insider jokes about this -- which in hindsight are probably not very PC, but this was 20 years ago after all.
My favorite was to say, 'this is a chair to keyboard problem' -- in other words -- the user him/herself. I know, don't chastise me. It wasn't nice.
Remote Control
These days about the worst user problem we ever encounter are homeowners upset because they think their pool controls or TV remotes don't work properly when the fact is, they have forgotten how to operate them. This is particularly true when they have more than one home and their controls differ.
Recently though, I experienced my first ever embarrassment over an issue with a client. That has never happened before and I'm still feeling the sting.
Our client has a tankless water heater and he said it took a little while to get the water hot. We had our plumbers -- a company with whom we've been working since we first started this company -- come out to investigate.
On the first visit, they said everything was fine and they recommended configuring the internal recirculating pump which will keep the hot water flowing rather than simply waiting for it on demand.
Plumber
Our client ok'd this but the water seemed to take longer and longer to heat. We then had the same company run diagnostics, even though the heater was not throwing error messages. No issues there.
I called the manufacturer who explained this is not an 'instant' hot water system but an 'on demand' system and that sometimes water can take a little while to heat.
I shared this with the client, but he insisted that the hot water previously came on in about 10 seconds where now it was taking minutes. He wasn't upset about the length of time so much as the water waste. Still, it needed to be fixed.
Tankless Water Heater
As someone who has yet to meet a problem I can't solve, I spent quite a bit of time researching tankless hot water heaters and determined that they need regular maintenance. Since this homeowner was new in this house (but the house wasn't new), we decided to do the maintenance.
Still no results. Finally, I called the company who installs these particular tankless systems regularly. Their technician came out and, you guessed it, the switch for the recirculating pump was not turned on!
O.M.G.! We have spent two weeks on this issue and have had our original plumber out three times -- and for what? A switch not being on! I am feeling the same flush of embarrassment now, as I write this, as I felt when we figured this out.
The client, as always, was very gracious and nonjudgmental -- he even said he was so happy he was running around the house running all the faucets! We're happy for him but still, we feel pretty awful about this.
However, and as is always the case, we did learn some valuable lessons in all of this:
  1. Tankless water heaters operate just like regular water heaters except they don't have a storage tank for the water.
  2. Tankless water heaters operate 'on demand' not 'instantly'. This means that when you call for hot water by turning on a tap, the tankless unit starts the heating process and delivers the hot water - not instantly (like an Insta-hot) but within a few seconds.
  3. Tankless water heaters need to have yearly maintenance. Maintenance consists of flushing the unit and descaling. Scale is hard water deposits. More scale means the tankless water heater cannot do its job properly. Descaling removes hard water deposits on the heat exchanger so it may heat as quickly as possible.
  4. This map,
    Water Hardness Map
    from https://water.usgs.gov/ shows that our Valley has extremely hard water. And if the water is extremely hard you definitely should have the unit flushed and descaled twice per year instead of only once.
  5. Hard water deposits can build up faster if you keep the tankless heater at an extra high temperature. If your thermostat reads greater than 120 degrees F, then it is best if you have your unit flushed and descaled twice a year.
  6. If you have the manufacturers name and the model number of your tankless water heater, it is pretty simple to find the operating manual online which has a description of all error code meanings and steps to take for resolution. It also has a 'problem' solving section that could help if your unit does not have error messages.
  7. For goodness sake, please check to see that the recirculating pump switch is ON.
