hot stick/ hot water heater add on
If you added the additional heater would you then NOT install the hot stick? Would this second heater feed into the original one? That way you would have 16 gallons of hot water if you used both propane and 120v, 10 gallons (with 6 gallons to be discarded) with 120v only or 6 gallons using propane only. If you did it the other way, you'd have to discard the 10 gallons when using propane only. Of course, discard is a relative term and could be minimized by correct timing usage.
If you get any kind of electric heater, a lighted switch is worth its weight in diamonds. I have a switch, but it is not lighted so the only way to see if it is on is wait and see if the water heats. I use the circuit breaker to turn it on and off...
I have no experiance with the hot stick, as the heater in my trailer came with a 120v/propane heater which works very well on 120v (i've not run it on propane yet). If it had not already had 120v capability, odds are very good I would have added a hot stick or equivalent, because getting the propane tanks out of my trailer to refill them is a long, painful process. Paying current propane prices is not pleasant either.
Must be nice to have extra space... I have to decide between extra underwear or extra food
