This is partially correct. YES propane provides more BTU's YES on many heaters you can use both at once for still faster recovery.
But it is also wrong. ON SOME heaters (Many Surburban models for example but not limited to) there are two thermostats one for Electric, one for Gas
On many others (Most Atwood models for example) there is but one set of thermostats that control both Gas and Electric via the control board (I say set because in addition to the primary T-Stat there is an Emergency Cut off.)
How hot the water is when you start your shower is NOT dependent on the number of BTUs. even a 400 watt Lightning Rod (yet another T-Stat) can get it up to 120 or 130 degrees. given enough time (1200 watts takes about an hour to do that)
But the temperature of the water is controlled by the thermostat.
So you have one of two situations.. Either the electric side T-Stat is set too low. or it's the wrong factory set model Either way it should be an easy fix.
