You say the perfect temperture for a shower is 115 degrees. I was wondering who that temp is perfect for.

Alot of ADULT folk like a HOT shower thus pushing their water temps up to 130, which is what the power companies always told me to set my water heater at. You state that 115 is the perfect shower temp so was wondering by whose standard you set that at.
Asked by: Lovnhart
The average person showers at temperature ranging form 100-115. Similar to hot tub temperatures which usually max out at 105. With a tanked heater you are told to set it 130 because the supply is limited and you make it last longer by mixing in cold water. With a tankless unit the supply is unlimited. So there is no need to heat it to 130 just us more water to cool it back down.

4.3 GPM Liquid Propane Gas Tankless Water Heater is rated 3.0 out of 5 by 9.
Rated 5 out of 5 by from Great purchase! This water heater does everything we wanted and more. Really like the limitless hot water provided by the unit. We are looking forward to a reduction in our energy bill due to the fact that the tank less heater does not reheat the water multiple times per day.

Rated 1 out of 5 by from Nothing but problems!!! This water heater has been a nightmare. We have followed all instructions and it will not ignite. Changed pressure regulators, got a dedicated tank for water heater, and it keeps giving an E2 code. checked trouble shooting guide and it was no help. I can't even find a plumber to come and look at it in North Dakota! Not sure what to do next. We have been messing with this thing for 2 weeks and have had no hot water. I need a phone number of someone to help. I give up. I will have to return it I guess!

Pretty quiet, easy to install and startup. I chose it because it was the smallest unit I could find that has direct vent so it's not burning inside air. It would be better for installation if the two ducts were a little farther apart.

Rated 5 out of 5 by from Simple install and great service! I installed this heater in a camper last year. The owner failed to drain before winter. He called to let me know it was leaking last week. I guess the hard freeze caused the problem. I was able to replace a 49 cent O-ring in the flow sensor in less than an hour. Most human errors cost a lot more than that!

Rated 2 out of 5 by from Bad experience We will be returning this water heater because it almost always give an error code of E2. There is no air in the lines and the gas pressure is good. The heater comes on and starts to work, then E2 comes on. Now, we can turn the hot water off, then back on again & it works fine. After spending almost $300 for a service man to put regulators on, it still give an error code of E2. Maybe we got the only bad one in the bunch, I don't know. Customer service offered to replace it, but we are changing brands.

Rated 1 out of 5 by from Good at first but didn't last Product worked good for a short period of time then stopped working. Called the company and emailed them several times but they have the worst customer service ever. Made promises they did not keep. Was told there is only 1 person to handle all the calls and emails. Finally, Home Depot came through and just replaced the product. That was a relief since we went over 2 weeks without hot water! Do not buy this product.
