I had researched this tankless water heater extensively to include it in my Axis/Vegas Crowd sourced Owners' Manual. Here is a link to the discussion I posted to the forum about the UNIQUE quality of this hot water heater -- that being you don't control the water temperature by adjusting the flow of COLD water to mix with the hot. You adjust the flow of the HOT water to control its temperature.

Here is a quote from my previous post:
"In reading the owners' manual adjusting water temperature in this water heater is counter intuitive to everything we do in regulating the temperature of hot water at a tap. Basically conventional wisdom says regulate the temperature by adjusting the amount of COLD water being mixed at the tap. In terms of this tankless hot water heater -- that is EXACTLY the wrong way to adjust the temperature.

Here is what the Girard GSWH-1 says about the operation of their system and how to increase and/or decrease hot water temperature at the tap or shower head:

"The Girard Products model GSWH-1 is a new 'induced-draft', tankless water heater designed specifically for Recreation Vehicles (RV). Its configuration and size are consistent with the tank based RV water heaters currently in use and is designed for OEM's and after market use by the RV industry. A main feature of the GSWH-1 is a Dual BTU burner, which is set by the Mode Switch to either HIGH (34,000 BTUs) or LOW (27,000 BTUs). The incoming water temperature will raise 40°- 60° (F) based on water flow.

A tankless water heater heats water while it is being used i.e., on demand. The output temperature of the water depends on the temperature of the inlet water AND the amount of hot water that is drawn."

In addition the manual says the Girard Tankless Water Heater operates at 40 - 60 psi.

If you have this tankless water heater you can save yourself a lot of grief by downloading it. Printing it. And reading it (like who reads owners manuals). I'm not trying to insult anyone's intelligence -- but -- this water heater does not operate like the tanked water heater we have in our RVs or home.
