I like the size of the heater - it is quiet but it does not get hot enough for me.

Hi Deborah, I am sorry you are not happy with the temperature of the unit. Regardless of your climate with that unit if you are using 4.5 gallons per minute or less, which would be 2 showers and a sink, or a bathtub and sink it would reach the max temperature of 120 degrees. 120 is the max temperature for residential water heaters. If that is not enough there are commercial chips available for $99.99 that will allow the unit's max temp. to go up to 180 degrees. If interested call me and we can one ordered for you. You have to be careful though, because with water that hot you can hurt yourself or others.

After it was installed and the gas was finally turned on it wouldn't start up. Turns out the thermostat had a short in it. We disconnected it and it works fine, just cant change the temperature. Have had no luck getting it replaced..
