Long Life

• The seamless, blow-molded polybutylene tank is impervious to rust and corrosion!

• Multiple layers of filament-wound fiberglass give the tank unmatched strength.

• The tank is designed, built and warranted not to leak "for as long as you own your home."

Energy Efficiency

• Envirofoam insulation is free of ozone, depleting CFCs and HCFCs so it saves the planet - and it saves energy.

• Pipe Wrap Energy Kit is included to reduce heat loss from plumbing lines.

Durable

• Recessed drain valve is out of the way of brooms and scrubbers.

• Tough molded outer shell resists dents and scratches.

• Bowl-shaped bottom allows more complete sediment draining.

Functional

• Factory installed temperature and pressure relief valve for greater value and security.

• Conduit between control boxes facilitates wiring for "off peak" use.

• All plastic tank eliminates the need for an anode rod - preventing odor problems.
