Hot water heater

No it is is not an on demand system like a Truma.  It is a 6 gal hot water tank system just like most homes have.  You can heat your water either by turning on the switch inside the POD (for using propane) or going outside and opening the cover to the water heater and turning on the switch ( for 120 volt electric heating).  And if you use alot of water and want to heat it up faster you can run both propane and electric at the same time (be careful and make sure you have water in the 6 gal tank by turning on the hot water faucet and having a good water flow).  We thought we would need to buy a Truma since 6 gal seems so small but glad we decided to try it first.  We have not run out of hot water even keeping it on for an entire shower.! So for us no need for an on demand system. The water pump is only needed when not connected to city water and you are using the water supply from your tank.  You also do not need to leave it on constantly but only when using water.  For example when we go to bed at night if we leave the pump on whenever the pressure drops the pump turns on and even though it is in the middle of the night and we have not used the water the pump comes on and it is noisy.  For that reason when dry camping we still only turn on the pump when using the toilet or turning on a faucet and then we just turn it off.

Never thought about a leak as it only cycles for a few seconds but will look into that. Thanks
