Consuming almost 30% of personal budgets, heating water ranks behind only heating and cooling homes in terms of household budgets. Nevertheless, gas water heaters are often ignored until they break down, often leaving families with flooded basements and only cold water in their taps, desperately contacting Ohio Water Heaters for the best gas water heater repair in Columbus, OH, and surrounding areas.

Equally suitable for families large and small, gas water heaters are available in a range of BTUs, with different storage capacities. Regardless of whether they burn natural gas or propane, the output of all gas water heaters is measured in British Thermal Units. Higher BTU ratings indicate more efficient equipment with shorter recovery times, with refilling water heated faster and with longer-lasting outflows.

Typically holding 40, 50, 55, 60, 75 or 100 gallons, gas water heater costs are dependent on capacity and efficiency, particularly as recent federal regulations now require water heaters to be more energy-efficient. Water heaters holding less than 55 gallons are now 4% more efficient, while larger models have efficiency gains of up to 50%, depending on the technology used.

Although daily hot water consumption may top 100 gallons, families may need a storage tank only half that size. The important factor here is the First Hour Rating, which is the number of gallons a water heater can deliver in an hour, starting with a full tank. This figure is shown on the Energy Guide Label. However, the best tankless gas water heater for any specific home depends on how many people are living there, how much hot water they use in a day, and their peak water usage requirements.


In most homes, busy mornings are usually the best time to estimate hot water consumption and discover what gas water heater services are needed. The figures vary widely: two showers, a shave and breakfast account for 47 gallons FHR; three showers, a shave, breakfast and a load of laundry account for 99 gallons FHR, with the washing machine accounting for a massive 32 gallons of gas water heater costs.

Depending on how much water you use, when you use it and how you heat it, energy costs might be halved, compared to regular storage models. However, higher up-front gas water heater costs mean that payback times might be longer.

Storage Tank Gas Water Heaters

Normally running on natural gas or electricity, these insulated tanks are fitted with temperature and pressure relief valves that open if either parameter exceeds a preset level. For added safety, they can be replaced quickly and easily by a gas water heater service. Although more expensive to purchase, natural gas water heater costs are about 1/3 the price of running an electric water heater.

Tankless Gas Water Heaters

Using coils to heat water on demand, tankless gas water heater installations are more energy-efficient than tanks, but with a more limited flow of hot water, at about 5 gallons a minute, depending on inlet water temperature. This means that they are more suitable for many homes, just make sure they are sized properly. They are also the best tankless gas water heater for homes that already heat water with natural gas, as switching to electricity might require an expensive system upgrade.

Wall-Mounted Gas Water Heaters

As tankless water heaters simply heat water as it flows through their structure, the Gallons per Minute (GPM) Rating is important, showing how much hot water heater can deliver during a specific length of time. The higher the GPM, the more hot water it delivers. As an example, a typical shower uses up to 2.5 GPM. So a large family with several bathrooms, frequent meals and endless loads of washing needs the best gas water heater it can afford, with the highest possible GPM.

For smaller families, the best gas water heater rating is 34,000 BTUs for a forty-gallon tank, with 36,000 BTUs preferable for a fifty-gallon tank. As an indicator, here are some average flow rates for common household appliances:

  • Bathroom faucet: 5 GPM – 1.0 GPM
  • Shower head: 5 GPM – 2.0 GPM
  • Kitchen tap: 0 GPM – 6.0 GPM
  • Dish washer: 5 GPM – 2.5 GPM
  • Clothes washer: 5 GPM – 3.5 GPM
