Questions & answers

Before you buy

Everything homeowners ask about installing and sizing a MRCOOL system.

Can I install a water heater myself?

Water heaters involve plumbing connections and a dedicated electrical circuit, and most areas require a permit and inspection. A licensed plumber or electrician is the safe route.

What tank size do I need?

Tank size follows household size and peak hot water demand. The capacity of this model is listed in the specifications.

What power does it need?

Electric tank water heaters need a dedicated circuit sized to the element wattage. The required voltage and wattage are in the specifications on this listing.

How long should it last?

Service life depends on water quality and maintenance. Flushing the tank periodically and replacing the anode rod when it wears out will both extend it.
