Vrapp,

I wouldn't worry about the anode, unless you're in an area with really hard water, or a lot of chemical or minerals, it has little to do with heating the water but,

You may want to remove one of the elements, and see if you have a heavy deposit of minerals attached on it,and the condition of the element.

Do you have a lot of deposits in the water when you drain the tank ?

That's about as far as I can get you, at this time.

Good Luck,
:) :) :)

Vrapp,

No, You didn't mention that it was a gas heated unit,

I made the mistake of assuming.

But some or most of the information I sent you is still relavent,

You could have a sediment build up on the inside of the tank,

Instead of draining the tank, you should also flush the tank.

(Drain the tank, once empty open the water valve to allow the tank to partially drain and flush the remainder of sediment from the bottom of the tank).

The other thing you want to check is the burner flame characteristics, blue flame, little to no white or yellow tipping,and should encompass the base of the tank(not too small, not too large) and no sooting on the bottom of the tank.

Good Luck,

:cool: :cool: :cool:
