Atwood uses a 1400W electric element and a 8000btu/6 gal or 10,000btu/10 gal burner (PER HOUR of Burn Time)
Heats water to 140*F where T-stat OPENS
**XT models use 160*F T-stat/Mixing Valve same 10,000btu burner
Suburban uses a 1440W electric element and a 12,000btu burner for all models (PER HOUR of Burn Time)
*4 gal uses a 9,000btu
1 Gallon of propane 91,500btu----do the math
Both use Dip Tubes on cold inlet and hot outlet
(Just like residential models)
Cold points DOWNWARD so it doesn't mix/dilute hot and creates a 'temp zone' that pushes the Hot out
Hot points UPWARD so the hottest water flows out
1400w1440w elements use roughly 11.5/12 amps @120VAC
If you have a Voltmeter installed...you can see a small deflection on voltage when it comes on and up tic in voltage when it goes off
***Amp meter would give better indication
Element when energized is 'silent' unless heavy scaling then it can 'sing'
Electric only...roughly 6.2 gal/hr recovery rate
Propane only ...roughly 10 gal/hr recovery rate
BOTH ...........roughly 16.2 gal/hr
*From initial cold temp
20-25 minutes for reheat cycle
Atwood 110*F to 140*F t-stat closes/opens
Suburban 110*F to 130*F t-stat closes/opens
IF you have short duration of hot flow:
Bypass Valve leaking thru diluting Hot out
Cold Dip tube has fallen off and Cold is quickly mixing/stirring Hot causing diluted temps
T-stat failing....opening too soon
