From standard storage tanks to high-efficiency hybrid and tankless systems, we offer professional-grade water heaters built to handle Arizona’s demands. Installed by licensed experts, our options deliver reliable hot water, longer lifespans, and energy savings compared to big box units.

Trusted Brands We Install: Bradford White, Rheem, Ruud, Lochinvar, AO Smith, GE, Rinnai, Navien, and more.

Standard 40/50 Gallon Electric or Gas 

Reliable and cost-effective, these standard water heaters are the most popular choice for Phoenix homeowners. Available in both gas and electric, they provide consistent hot water for families while offering the best balance of performance and affordability.

75 Gallon Bradford White Gas Water Heater

Perfect for large households or higher hot water demand, the 75-gallon Bradford White delivers plenty of capacity without running out. Built with professional-grade components, it offers a longer lifespan and greater efficiency compared to big box units.

80 Gallon Bradford White Electric Water Heater

Designed for homes with heavy hot water use, the 80-gallon Bradford White Electric combines capacity with durability. With professional-grade construction, it ensures dependable hot water while lasting longer than standard store-bought models.

Gas Tankless Navien Water Heaters

Tankless systems heat water on demand, giving you endless hot water while saving space. High-efficiency Navien models are ideal for Arizona households that want modern convenience, lower utility bills, and long-lasting performance.

Hybrid Electric Water Heaters

Hybrid water heaters use advanced heat pump technology to cut energy costs by up to 60%. They provide reliable hot water for Phoenix families while being eco-friendly and efficient — the perfect upgrade for homeowners who want long-term savings.
