In reply to ED. Hey Ed, I see it has been a while since your post but I am having the same problem. Did you ever get it fixed? I have been surfing looking for an answer but have not found anything yet.

I bought a Paloma PTG-42-PV about 4 years ago. After listening to my wife yell at me too many times about no hot water, I pulled it out. The slightest blink in the power and it shuts off. We live in the country, so our power is not the cleanest. I should not need to buy a battery back-up for a water heater! Also, I had to remove all the flow restrictors to get the faucets to flow enough to get the thing to fire! The dishwasher still will not pull enough to fire it. It takes 3/4 gpm to fire this unit, most other heaters take only 1/2 gpm. If having a well might be a problem with these things, it should be stated. I have installed 2 Bosch units for people and they have had no similar problems. I tried to contact their non-existant customer service depart at least 4 times and have had no response to date. This is to say I never miss an opportunity to let anyone within earshot about my experience with the company and it’s product. I reinstalled it again when the electric tank I replaced it with started to leak. Again I was having the same problems.
I made a sort of hybrid system by installing a 12 gallon electric tank after the tankless unit to take care of most of the problems we have been having.

My paloma 7.4 has been shutting off for 3 weeks intermittently. it gives a code that does not show up in the manual. I have spent more on repair calls to have guys show and tell me they have to order parts from paloma but they don’t know whaqt the problem is because the code means nothing to them. don’t buy one. . it’s a piece of sh!t.

I bought the 7.4 unit about 4 years ago and installed it without removing my 50 gallon water heater, and so far have not needed to use the tank water heater. I have developed a problem this week, where the control system has shut down on me with no codes, I turn it back on and run for a logn time then the next day, I find it powered off agian. I’m going to make sure adequate water is going through the unit and make sure the inlet water filter is clear. Vents are clean and there is adequate ventilation. Has worked flawless until these recent issues. Hopefully something minor. I have saved a lot of money with this unit. I’m extremely satisfied. I was going to buy the Bosch unit but at the time they could not match the specs on the Paloma.

I get a lot of work from Home Depot in Florence Kentucky and on more than one occaision I’ve been given Paloma brochures to read up on the product in case I get called/referred to install one. I believe they told me that they sell about 3-4 Paloma tankless water heaters a month and I do get calls for pricing, but for the most part the purchasers take it upon themselves to do it themselves.

The Home Depot in my area has been selling Paloma Tankless Water Heaters for some time, and they bring in a product display truck on customer appreciation days to show off their product line. Soon enough I’ll be installing one of these units for a customer in my area.
