If you need a gas water heater around 60 gallons, the closest listed storage option is a 65-gallon commercial Rheem-Ruud model. The other four picks are gas tankless alternatives, which heat water on demand rather than storing it. Choose the 65-gallon unit if tank storage is essential; consider the Rheem or MIZUDO for higher whole-home demand, or the APUS for a more modest stated flow rate. The FOGATTI is the outdoor-installation option.
| Product | Type | Best For |
|---|---|---|
| Rheem-Ruud 65 gal. | Commercial storage | Buyers seeking a tank near 60 gallons |
| Rheem RTG 7.0 GPM | Indoor tankless | Homes with 2–3 simultaneous showers |
| MIZUDO 10.3 GPM | Indoor tankless | Busy households needing high stated flow |
| APUS 4.42 GPM | Indoor tankless | Smaller simultaneous hot-water demand |
| FOGATTI 8.1 GPM | Outdoor tankless | Buyers planning outdoor installation |
Rheem-Ruud 65-Gallon Commercial Gas Water Heater
This is the closest match for shoppers searching for a 60-gallon gas water heater with a storage tank. The listed model is a 65-gallon commercial gas water heater with a 360,000 BtuH rating. Its manufacturer is Rheem-Ruud, and the listed country of manufacture is the United States.
Best for: Buyers who specifically want stored hot water and are considering a capacity slightly above 60 gallons. It was selected because it is the only listed product that is a gas storage-tank heater.
Limitation: This is identified as a commercial model, not a standard 60-gallon residential unit. The supplied details do not specify efficiency, dimensions, recovery rate, or installation requirements, so verify those before purchase.
Rheem RTG 7.0 GPM Indoor Tankless Heater
This natural gas, non-condensing tankless model provides up to 7.0 GPM at a 35°F temperature rise and has a 160,000 Btu/hr output. The listed features describe it as suitable for whole-house residential use and 2–3 simultaneous showers. It uses indoor direct-vent installation and a wall-mounted design.
Best for: Households that want an indoor, space-saving alternative to a storage tank and have demand within the stated flow conditions. It was selected for its clearly stated flow rate, temperature-rise figure, and residential application.
Limitation: It does not store 60 gallons of hot water. The 7.0 GPM figure is specified at a 35°F temperature rise, so actual output depends on incoming-water temperature and demand.
MIZUDO 10.3 GPM Indoor Natural Gas Tankless Heater
The MIZUDO is an indoor tankless model listed with 199,000 Btu of heating input and up to 10.3 GPM. Its features describe support for simultaneous demand across bathrooms, faucets, laundry, and dishwashers. Temperature adjustment is listed from 95°F to 149°F, with a default comfort setting of 107°F and stated temperature control within ±1°F.
Best for: Busy households comparing tankless options with a high stated flow rate and adjustable temperature range. Its listed 0.53 GPM low-flow activation may also matter to buyers who want operation at lower fixture flow.
Limitation: It is not a 60-gallon storage heater. The product listing’s broad outlet claims do not replace checking the home’s incoming-water temperature, gas supply, and simultaneous demand.
APUS 4.42 GPM Indoor Tankless Heater
This indoor natural gas heater is listed at 95,000 Btu and 4.42 GPM, with a 0.66 GPM low-flow start. Its adjustable temperature range is 95°F–140°F, and the product description states temperature control within ±1°F. Listed features also include an LED touchscreen, 120V power, and an anti-freeze function.
Best for: Buyers who want an indoor tankless unit with a lower stated maximum flow than the other high-capacity options. The listing describes support for two showers and one sink, making its stated use case easier to compare with household demand.
Limitation: Its 4.42 GPM rating is lower than the Rheem, MIZUDO, and FOGATTI figures here. It is not a direct substitute for a 60-gallon storage tank.
FOGATTI 8.1 GPM Outdoor Tankless Heater
The FOGATTI is an outdoor natural gas tankless model with a listed maximum flow of 8.1 GPM and 180,000 Btu. Its features describe use across 3–5 outlet points, temperature control within ±1°F, a remote control panel for indoor operation, and a four-stage combustion system.
Best for: Buyers who specifically need an outdoor tankless configuration and want a higher stated flow than the APUS. It was selected because its installation location and remote-control arrangement distinguish it from the indoor options.
Limitation: Outdoor installation is a defining requirement, so avoid this model if the planned location is indoors. It also heats on demand rather than storing a tank of hot water.
Buying Guide: How to Choose a Gas Water Heater
Do you need a storage tank or tankless design?
A 60-gallon storage heater holds heated water for use. Among these products, the Rheem-Ruud 65-gallon commercial model is the only storage-tank option and is the closest capacity match. Tankless models heat water as it flows, so compare them by fuel type, flow rate, temperature rise, and installation style—not gallon capacity.
How much simultaneous hot water do you use?
List the fixtures and appliances that may run at the same time. Compare that demand with the stated tankless flow rates: 4.42 GPM for APUS, 7.0 GPM for Rheem at a 35°F rise, 8.1 GPM for FOGATTI, and up to 10.3 GPM for MIZUDO. Those figures are not identical test conditions, so consult the product specifications for the conditions behind each rating.
Where will the unit be installed?
The Rheem RTG, MIZUDO, and APUS are listed as indoor units; FOGATTI is designed for outdoor installation. Confirm venting, available space, gas supply, electrical needs, and local code requirements with a qualified installer. Check the commercial Rheem-Ruud unit’s requirements separately because the provided details do not describe them.
What should you verify before ordering?
Confirm natural gas availability, household demand, required temperature settings, and the model’s installation instructions. For tankless choices, check whether the flow rate fits your incoming-water temperature and peak use. For the 65-gallon commercial heater, verify that a commercial model is appropriate for the intended application.

Is a 65-gallon heater a reasonable alternative to a 60-gallon model?

Which listed product is an actual gas storage water heater?
The Rheem-Ruud 65-gallon commercial gas water heater is the only listed storage-tank product.
Are tankless heaters measured in gallons?
These products are compared by flow rate in gallons per minute, not tank capacity. They heat water on demand rather than storing a stated number of gallons.
Which option is designed for outdoor installation?
The FOGATTI 8.1 GPM model is described as an outdoor tankless water heater.
