Can I increase the wattage to a higher wattage when replacing
and element?
Do to liability, we never recommend that you increase the element wattage over the original
element installed by the manufacturer.
Which is better, one element or two?
Absolutely two elements! In our minds, there is NO doubt about which is best;
two elements!
Most two element systems work like this: The upper element goes on first and
once it is hot enough on top then the lower element goes on. If the water
you are getting out of your heater comes from the top, why would anyone think
that heating the bottom only is better? We think the only reason is to save
manufacturing costs.
Do you think electric water-heater timers are worth it?
In almost all cases they should pay for themselves in a short time.
