Tankless units like the Rheem RTG-70XLN-3 and GASLAND Gasmart E 199,000 BTU were considered for their efficiency but ultimately focused on tanked gas models given the 50 gallon specification. We favored units with strong safety features like exclusive shut-off devices and durable anode rods.
What Most Buyers Get Wrong
BTU: The Muscle Behind Your Hot Water
For gas water heaters, the BTU (British Thermal Unit) rating is crucial. It tells you how much power the unit has to heat water. Higher BTUs mean faster heating and the ability to meet high demand, especially important for larger families or homes with multiple bathrooms.
Look for models like the Rheem RTG-95DVLN-3 (199,900 BTUs) or GASLAND Gasmart E (199,000 BTU) if you need robust performance, ensuring you won’t run out of hot water during peak usage.

Tank Type vs. Tankless: It’s About Predictability
When selecting a best gas water heater 50 gallon, the fundamental decision boils down to whether you prioritize consistent, readily available hot water or demand-driven, potentially unlimited supply.
Traditional tank models, like the Rheem PROG50-42N RH67 PV Professional Classic Residential 42K BTU Power and the Rheem PROG50-36P RH62 Professional Classic Tall Residential 36K BTU Atmospheric, are built for predictable output. They maintain a stored volume of hot water, ensuring that as soon as a faucet is turned, hot water is delivered. This characteristic is invaluable for households with synchronous demands – think multiple showers running simultaneously during morning routines or a dishwasher and laundry cycle kicking off at the same time.
Their limitation, however, is the finite nature of this stored supply; rapid, sustained use will eventually deplete the tank, leading to a period of cooler water until it can reheat.
Tankless units, conversely, like the Rheem RTG-70XLN-3 High Efficiency Non-Condensing Outdoor Tankless Natural Gas Water, Rheem RTGH Series 8.4 GPM 157,000 BTU 120, and the GASLAND Gasmart E 199,000 BTU Tankless Water Heater, provide hot water on demand. This means you can theoretically run hot water indefinitely, as the unit heats water only when the flow is detected. However, their performance is directly tied to flow rate and BTU input.
For instance, the Rheem RTG-70XLN-3 is specified at 7.0 GPM, suitable for 2-3 bathrooms, whereas a larger unit like the Rheem RRTGH84DVLN3701171 Rheem RTGH Series 8.4 GPM 157,000 BTU 120 can handle more simultaneous demands. The critical factor here is matching the unit’s GPM capacity to your household’s peak simultaneous hot water usage.
Underestimating this can lead to tepid water during high-demand periods, a situation less common with tank heaters.
The Rheem PROE50 M2 RH95 50-Gallon Professional Classic Medium Residential Electric and the MRCOOL 50 Gallon Electric Water Heater 4500W Tank, High Efficiency, while not gas, serve as a point of comparison for the sheer volume a 50-gallon tank can offer, highlighting the buffer provided against immediate depletion. While electric models have their own recovery rates, the concept of immediate availability from stored water remains. For those who consistently face multi-point hot water demands around the same time each day and cannot tolerate any interruption, a tanked model, even if it’s a gas option like the Rheem PROG50-42N RH67 PV Professional Classic Residential 42K BTU Power, remains the more predictable choice.
Ultimately, the Rheem RTG-95DVLN-3 High Efficiency Non-Condensing Indoor Tankless Natural Gas Water is an excellent selection for larger homes where the BTU output and high GPM can consistently serve multiple fixtures without issue.
How to Choose the Best Gas Water Heater 50 Gallon
Fuel efficiency and energy factor ef
When selecting a 50-gallon gas water heater, prioritize a high Energy Factor (EF) rating, typically above 0.60 for standard models and reaching 0.80 or higher for high-efficiency units like condensing gas heaters. A higher EF directly translates to lower monthly energy bills, as it quantifies how much energy is used for heating water versus wasted. For example, a heater with an EF of 0.80 is 80% efficient in converting gas to hot water.
Aim for the highest EF your budget allows, as the long-term savings will outweigh an initial higher purchase price. Choose a condensing gas water heater for maximum energy efficiency.
Ignition type: pilot light vs electronic ignition
The ignition system significantly impacts gas consumption and convenience. While traditional standing pilot lights are reliable and require no electricity, they continuously consume a small amount of gas. Electronic ignition systems, on the other hand, only activate when hot water is needed, drastically reducing standby gas loss and improving overall efficiency.
For maximum gas savings and a more eco-friendly operation, opt for models with electronic ignition. This technology is standard on most modern, high-efficiency gas water heaters.
Ventilation system requirements
Ventilation is critical for both safety and performance. Direct vent systems draw combustion air from outside and exhaust directly through a wall, offering flexibility in installation location and superior energy efficiency as they aren’t affected by house air pressure. Natural vent systems rely on ambient air from the surrounding space and vent through a chimney or flue, requiring specific installation locations and adequate make-up air.
For ease of installation and optimal performance in most homes, choose a direct vent gas water heater.
Which Should You Choose?
- If you have a household of 3-5 people and need ample hot water for multiple bathrooms, choose a model with a capacity of 50 gallons or more with a high BTU rating for fast heating.
- If you prioritize space-saving and easy replacement of an existing unit, look for a compact 50-gallon model that is designed for direct installation.
- If you need unlimited hot water for a busy household with multiple simultaneous demands, consider a high-flow tankless gas water heater with a high GPM (gallons per minute) output.
- If you are looking for an eco-friendly option with reduced emissions, opt for a gas water heater that meets low NOx requirements and features an efficient burner.
Quick Best Gas Water Heater 50 Gallon Buying Checklist

Frequently Asked Questions
What Is The Difference Between Direct Vent And Natural Vent For A 50-Gallon Gas Water Heater?
Direct vent models use a sealed combustion system drawing air from outside and venting through a wall or roof, making them ideal for indoor installations. Natural vent models require a vertical chimney to expel exhaust gases, typically installed in basements or garages.
How Does The Energy Factor (Ef) Impact My Bills On A 50-Gallon Gas Water Heater?
The Energy Factor (EF) indicates a gas water heater’s overall efficiency, with higher numbers meaning less wasted energy. A higher EF rating on your 50-gallon unit will directly translate to lower monthly gas consumption and reduced operating costs over time.
Is Electronic Ignition Better Than A Pilot Light For A 50-Gallon Gas Water Heater?
Electronic ignition systems are generally more fuel-efficient as they only activate when hot water is needed, unlike pilot lights that burn continuously. While pilot lights offer simplicity, electronic ignition contributes to cost savings on your 50-gallon gas water heater.
What Are The Typical Warranty Lengths For A 50-Gallon Gas Water Heater?
Most manufacturers offer warranties ranging from 6 to 12 years for the tank and parts on their 50-gallon gas water heaters. Some premium models may extend this coverage. It’s crucial to review the specific warranty details for each model.
Why Is A 50-Gallon Size Often Recommended By Experts?
A 50-gallon capacity is a versatile choice that generally meets the hot water needs of most medium-sized households. It balances sufficient hot water supply for simultaneous use, like showers and laundry, with reasonable energy consumption.
Final Words
Choosing the best gas water heater 50 gallon ensures reliable hot water for your home while offering energy efficiency.
