You got it! When I use the shower, I start the water flow full on at the hot setting. Wait two minutes and test; if too cool, slow the flow or up the temp setting. If too hot, lower the temp setting and for those with Gen 1, go to the lower setting. If still too hot, push the shower control off and quickly move ever so slightly to a cooler setting and pull open. This generally isn't easy, but that's how the Girard operates. Basically, you control the temperature by playing with flow. The higher pressure that you have coming in, the better.

Stephen,
You should not be pulling water from your tank unless the water pump is running. I would check to make sure that the water pump is not on.
As for getting the air out, turn on all of the taps (one at a time) and let the water run until you get a steady stream without any 'sputtering'.

Worked great! I had the pump on
Thanks Tom

1. Turn on water, the Girard senses flow and fires the burner at the BTU setting (High/Lo for Gen 1 and variable for gen 2).

2. If the water is set very low by you, the water in the heater will reach 122 degrees very fast and shut down for a moment. You will then get very hot water at the slow flow followed by cold and then hot again - not good!

3. So it is too hot, so you set the faucet flow higher and you get continuous very hot water without cold spurts. Problem is that you can't get higher flow, which is dictated by your water source pressure.

4. To reduce the high temperature, you then need to vary the BTU setting (say to low for Gen 1 or lower temp with Gen2). This may or may not work.

5. To reduce too high temps, you might think about mixing some cold water. Girard frowns upon this, because you will lessen the flow through the heater and it will then even get hotter and shut down. Another problem is that the shower valve in the Berkshires doesn't mix hot and cold water very good.

6. Basically, the Girard water heater has absolutely no output temperature control. With a hot water faucet open, all the Girard knows is fire the burner at your setting and shut down if the temperature reaches 122 degrees. This leaves you to try to control temperature with water flow setting which isn't always easy and is compounded by having different pressures at different parks.

The Girard Tankless would be an excellent heater if it had a variable flow gas valve with a controller that compared your desired temperature (set on your wall) with the actual output temperature. The controller would constantly adjust the burner's gas flow to achieve the desired temperature. Water flow would be of hardly an issue. Unfortunately, the Girard does not work that way, but I believe the Precision Temp RV-500 does.

Are there any Berkshire owners with an after-market Precision Temp installed, Like to hear from you.

Hank
Is it just me or does it seem that a rocket science degree needed just to get some continuous hot water with this tankless water heater? With the old propane/electric water heater you just turned it on and you had a steady flow of hot water. OK, you may not be able to take a 15 minute continuous shower and may have to wait a few minutes between showers, but it was a lot easier than the Girard system. Now you need to make sure that the temp is set on the control knob, that your water pressure coming in is sufficient, that you take into account the ambient temperature of water coming in, that you make sure that there is no air in the system, and on and on.
Seems like Girard, or someone, should be able to come up with a system that is easier to use and provide the same level of continuous hot water without all the adjustments and refinements that need to be made continuous trial and error tests.
I guess I am just getting very frustrated with this 'better' system.

Tom their is it's called Aqua Hot and comes on most DP now. Well most that cost 300,000 and up.
In the mean time I think you will get the hang if the Garrard It's a little temperaments but I find it worth while.

I totally agree with you. As I stated, I believe that the Precision Temp RV 500 is better. It monitors the output temperature and controls the gas automatically. That is the way it should be. See the Specification section and Controls paragraph of....

http://www.precisiontemp.com/rv-500-...-water-heater/

The Precison Temp is almost the same size as the Girard; if it wasn't for the price I would probably change. I wish that FR would awake up. I guess that because the Girard is about half the cost of the Precision Temp, FR is trying to save a nickle when compar to the cost of the MH, IMHO!

My Garrard must be stuck on full temp, I have it set as low as I can and the cold water in cool enough. When the hot comes on full it is scolding, and then it goes cold. The little flap valve is clean. DW is not happy.

Do you have the model with the temp control in the bathroom cabinet? Looks like you have a new coach so I'm guessing so.

The #1 solution in most cases is to be sure you don't have air in the lines. Run both the hot water and cold water on each tap until they're not sputtering. When I hook up city water the first thing i do is run the outside shower to bleed any air that was in the hose. Once you've run all the faucets and have the air out of the lines, turn the hot water on and wait 60-90 seconds...it should be stable at that point. I've found it very hard to convince DW not to try to manage water temp using hot and cold water. Hot on all the way in the shower then adjust the temperature knob for a comfortable but not hot shower. If hotter water wanted, turn DOWN the hot water a little. that slows the flow thorough the tankless and heats the water more before it sends it on to the shower.

Once my lines were bled, we had stable temps. If shower on full blast was too cool then we'd bump the temperature control and wait 60 seconds. Smooth sailing.

Thanks, I have no sputtering at all at any of the outlets. Yes ours in the one with the knob in the bathroom cabinet. The knob is currently set to low.

I understand your frustration. I realize I was restating things you may have read here before, but often air in the system is the culprit. Mine was all over the map until I ran the washing machine through part of a cycle (tip I got here.)
