Storage Water Heaters
Storage tanks are the most common water heater found in homes due to their lower upfront cost, flexible sizing, simple installation, and multiple heat source options. Their ability to store large volumes of hot water makes them well-suited for use in several locations at once.
Vaughn storage water heaters are available in electric, solar, heat pump, and indirect configurations (heated by steam or boiler water). What sets them apart is the ½" HydraStone cement lining that covers the entire tank interior. Unlike glass-lined models, Vaughn HydraStone tanks require no anode rod maintenance and last decades in demanding conditions. The result is a more durable, lower-maintenance option for long-term performance.
The Featherweight storage water heater line offers a lighter alternative without compromising performance. They’re ideal for applications where weight, access, or water chemistry are concerns. With thermoplastic storage vessels, shipping weight is as low as 85 lbs and handling is easy. They’re built to resist corrosion, maintain water quality, and operate with low standby heat loss. No anode rod is required, and the factory-installed copper heat exchanger is fully removable for service.
Heat Pump Water Heaters (HPWH)
A heat pump water heater uses far less electricity than a standard electric model to produce the same volume of hot water. It works like a refrigerator in reverse, drawing heat from the surrounding air and transferring it into the tank. This process takes advantage of ambient heat, making it a highly efficient option.
Most heat pump water heaters focus on efficiency and stop there. Vaughn goes further. The Vaughn MK II is ENERGY STAR® 5.0 certified depending on the specified KW and gallon capacity. It’s engineered to outperform and outlast, featuring our signature HydraStone cement lining—a proven defense against the corrosive effects of hot water. That’s a level of protection conventional glass-lined tanks can’t match.
The Vaughn Featherweight HP brings high performance in a lightweight package. Our innovative, ultra-lightweight thermoplastic tank makes it easy-to-handle and install. It requires no anode rod, cutting out a major maintenance concern. 3" of high-efficiency insulation means the tank holds heat longer. Freeze protection, four operating modes, and ducting flexibility make it suitable for a wide range of applications.
As of early July 2025, homeowners and commercial properties that install qualifying hybrid water heater models can take advantage of federal tax credits. These can offset up to 30% of the purchase and installation costs. Many states also offer additional rebates. The investment in energy-efficient heat pump water heaters, like the Vaughn MK II and Featherweight HP, is more affordable and practical than ever.
To conclude
Water heaters vary widely in design and performance. Selecting the right one means balancing factors to suit your specific needs. Reach out to us at Vaughn to identify the solution that works best for your situation.
