12 Frequently Asked Questions About the RV-500 Water Heating
System
| What makes the RV-500 special? |
It delivers instantaneous, continuous and endless hot water for
as long as you want. You can literally shower for hours. |
| How can the RV-500 provide endless hot water? |
The RV-500 has no tank. Water is heated instantly to 115ºF
only when you request it. No propane is used to keep unused water hot. |
| How do I get the RV-500 to heat hot water? |
Simply turn on a hot water faucet. A flow meter in the RV-500
is activated and the heater automatically comes on to heat water. When
you turn off the faucet, the burner shuts down. There is not even a
pilot light. Simply turn on a hot water faucet. A flow meter
in the RV-500 is activated and the heater automatically comes on to heat
water. When you turn off the faucet, the burner shuts down. There
is not even a pilot light. |
| How long does it take to have hot water? |
The RV-500 begins making hot water in about three seconds. The
water temperature will rise rapidly to the set temperature (115º
F). |
| Does the RV-500 install like other water heaters? |
Yes. It installs and flues like a tank heater, in the side
walls of your RV. The water, gas and electrical hookups are the same type
used on tank heaters. |
| Will the RV-500 fit into the same bay in my RV's
side-wall? |
In almost all instances it will. The RV-500 mounting flange
is designed to perfectly replace a common ten gallon tank heater. To
replace a six gallon heater, a few inches must be added to the vertical
dimension. This can be cut up or down. |
| Is the RV-500 as noisy as my current tank heater? |
No. It is so quiet that the only way you know it's operating
is that you have hot water |
| Does the RV-500 use more propane than tank heaters? |
To the contrary, the RV-500 is about 20% more efficient than tank
heaters. And, because there is no standby heat loss, you may find that
you are using 1/2 or less the amount of propane per gallon of hot
water. |
| How do I winterize my RV-500? |
Simply drain the system of water, blowing it out with air, or
else running non toxic anti-freeze through the heater while winterizing the
rest of the plumbing system. The RV-500 only requires about a pint
of antifreeze. |
| If endless hot water is such a good idea, why doesn't
everyone use it? |
Most people don't realize that they have an alternative to tank
heaters. It takes a lot of time and marketing dollars to get the word
out. But for those who want endless hot water and a quiet and efficient
hot water system, the RV-500 is perfect. |
| When operating, does it create as hot an exhaust as my tank
heater? |
No. It is about 50% cooler. It will not scorch the
side of your RV. |
| Can I buy direct from the factory? |
Yes, or through a local dealer. |

| Model RV-500 |
Operation: When unit is powered, the microprocessor activates the gas
modulation valve and per-forms component diagnostics. A green LED will flash
for normal operation, red will indicate a malfunction, signified by different
codes. The unit will remain dormant until the rotary flow meter senses at
least .4 GPM of water flow. The gas modulating valve will be set to its ignition
value, the spark will be effected and the gas valve will open. Ignition
will occur and the flame will be proofed.
The microprocessor now reads water flow rate, and incoming water temperature,
calculates the required gas flow to maintain set temperature and sets the
gas modulation valve to the proper setting. The water temperature is then
monitored by the thermistors midway and at the outlet to make any minor
corrections in gas flow. If there is any change in water flow or incoming
water temperature, the microprocessor recalculates and makes any required
adjustments.
The unit continues to produce hot water until water flow is stopped and the
burner turns off. |
