“My only regret is that I didn’t have my geothermal installed years earlier.”
The technicians are not only pleasant but they are extremely knowledgeable. Atel Air stands by their product and are always easy to contact even when you have a problem.

“We can now fill up our oversized bathtub without running out of hot water!!”
We had Atel Air install a new On-Demand hot water system. They did an amazing job, rerouting ductwork and pipes, leaving the furnace room neater and tidier than ever.

Terms You Need to Know

Understanding key Water Heater terms can help you make more informed decisions about your options.

BTU (British Thermal Unit)
Indicates the heating capacity of either a tank or tankless water heater. Allows you to know how much heat the unit can produce per hour.
GPM (Gallons Per Minute)
Important for tankless units, GPM is the hot water flow rate per minute, which impacts how many fixtures the unit can support simultaneously.
Uniform Energy Factor (UEF)
An energy efficiency measure for tank and tankless models. A higher UEF means the unit is more efficient, translating to energy and cost savings.
Recovery Rate
Indicates how quickly a tank water heater can heat and deliver water after the initial supply is used. (i.e. how long you can expect to wait for more hot water)
Activation Flow Rate
The minimum water flow required to activate a tankless water heater. Useful for understanding compatibility with low-flow fixtures.
First Hour Rating (FHR)
Important for tank-style heaters, FHR shows how much hot water the unit can supply in the first hour of use, combining the tank’s capacity and recovery rate to give a realistic measure of output.
Temperature and Pressure Relief (T&P) Valve
A safety feature for tank models that releases water if the tank becomes over-pressurized or overheated, protecting the unit and the home.

Frequently asked Questions

Which water heater is right for me—tank or tankless?

Tankless water heaters are ideal if you frequently run out of hot water, want to lower energy bills and save space, or travel often. Traditional tanks are a good choice if you’re home most of the day, need a lower upfront cost, or plan to sell your home soon. Contact us to learn about the benefits of each option and find the best fit for your home.

Can I switch to a tankless water heater?

Yes, switching to a tankless water heater is often possible, though it may require some adjustments, like a new gas line or venting. We recommend brands that integrate well with existing systems for a smoother transition, and ATEL Air’s licensed experts ensure professional installation.

Are tankless water heaters more expensive than tank models?

Tankless water heaters generally cost more upfront but save on energy in the long run, and they can also add value to your home.

How can I make a new water heater more affordable?

We offer flexible financing options with manageable monthly payments to make upgrading your water heater easier on your budget.

When Should You Repair or Replace Your Water Heater?

Wondering if it’s time to replace your water heater or keep it running? Here are a few things to think about:

How old is your water heater?
Most water heaters have a lifespan of 10+ years. If yours is nearing this age, replacement might be more cost-effective, as newer models offer greater efficiency and reliability. Tankless models can last up to 20 years.
Are repair costs adding up?
Frequent repairs can become costly over time. If you’re calling for service often, replacing your unit may provide better long-term value and peace of mind.
Does your water heater deliver enough hot water?
If your hot water runs out quickly, or heats unevenly, it may be nearing the end of its life cycle.
Are your energy bills increasing?
Older water heaters tend to be less efficient, which can lead to higher energy costs. Replacing an outdated unit with an energy-efficient model can help reduce monthly utility bills.
Is there visible rust or corrosion?
Rusty water, visible corrosion, or leaks around your tank are signs that the water heater is deteriorating. In these cases, replacement is often the safest choice to prevent tank failure.
Are you interested in upgrading to tankless?
If you’re considering an upgrade, tankless water heaters can offer long-term savings, energy efficiency, and continuous hot water.

Still not sure? Contact us for help to determine the best water heater for your home.
