Hott Rod & Lightning Rod are two aftermarket electric heat elements that install in drain hole of water heater tank.
Both are low wattage elements and can be a source of supplemental heat...great for maintaining hot water but very slow in recovery time.
Both have adapters for use in Atwood (1/2") or Suburban (3/4") drain holes and also have a small anode rod adapter for use in Suburban Brands (needed!)
Both Atwood & Suburban will void any warranty if they are used.
Not OEM equipment and because they go in the drain hole folks have a tendency to NOT drain & flush tank.
Replacing with a combo electric/gas model can be done......
Need to stay with same brand and size otherwise opening in side of rig would need to be modified.
Also would need AC circuit breaker, switch and wiring added.
Depending on brand may have to have 12V DC power also..Atwood uses a DC relay to energize AC power to element.
Is it time for your medication or mine?
