Signs it's time for a new water heater

What you might be seeing

Seeing one of these? Call (256) 221-2847 and tell us which number. It helps us plan the visit.

  1. The tank is ten years old or more

  2. Rust or a leak coming from the tank itself

  3. Repairs keep adding up

  4. You run out of hot water more than you used to

  5. You want a tankless heater or a bigger tank

A new water heater is a big purchase, and it’s easy to buy the wrong one. We size it to your house, install it properly and take the old tank with us.

New water heater installation in Huntsville

Most calls for a new water heater start with a leak or a tank that won’t heat anymore. Before we price a replacement, we check what you have: gas or electric, how many gallons, where it sits, and how it’s vented. Then we recommend the size that fits your household and your space.

A family that runs out of hot water every morning may need a bigger tank. A couple in a smaller house may not need the 50 gallons they have. We explain the trade-off and let you choose.

Gas and electric water heater replacement

Gas tanks need a proper flue connection and a sound gas line with a shut-off valve. Electric tanks need the right breaker and wire size. On every replacement we also look at the parts around the tank. That means the cold water shut-off, the temperature and pressure relief valve and its discharge pipe, and the drain pan. If your main line has a pressure-reducing valve, we add an expansion tank so pressure has somewhere to go.

When the job is done, you have a tank that’s filled, heating and checked for leaks. The old one leaves in our truck.

Tankless water heater installation

A tankless heater heats water as it flows, so it doesn’t run out and it frees up the space a tank took. It’s a good fit for some Huntsville homes and a poor fit for others. A gas tankless unit needs enough gas supply and its own venting. An electric one needs a large electrical service.

We check both before we recommend one. If your house can’t support it without major work, we’ll tell you, and a new tank may be the better choice.

Water heater sizes for Huntsville households

Most homes here run a 40 or 50 gallon tank. A household of one or two people usually does fine with 40 gallons. A family of four or more with a big tub or several showers each morning is better served by 50 gallons or more, or by a tankless heater. A bigger tank costs more to buy and keeps more water hot all day, so we match the size to how your house actually uses hot water.

Hot water heater replacement in attics, garages and closets

Plenty of homes around Huntsville have the water heater in the attic or a hall closet. These are the installs where a pan and drain line matter most, because a leak lands on the ceiling or the floor below. Attic and closet tanks go in a pan with its own drain line.

If your old tank failed but some parts are still good, water heater repair may be the cheaper answer. We also install water heaters in nearby towns, including Madison and Decatur.

How a water heater installation job goes

From the first call to clean-up

  1. Step 1: Match the heater

    We look at the fuel, the space, the venting and how much hot water your house uses, then recommend a size.

  2. Step 2: Price it up front

    You hear the price for the heater and the install, including any new valves or an expansion tank.

  3. Step 3: Swap the tank

    We drain and disconnect the old tank, set the new one, and connect water, gas or power and venting.

  4. Step 4: Fire it and haul off

    We fill it, bring it up to temperature, check for leaks and take the old tank with us.

Questions about water heater installation service in Huntsville

How long does a tank water heater last?

Most tank water heaters last around 8 to 12 years. Sediment, high water pressure and heavy use shorten that. A tank that leaks from its own seams is done, whatever its age.

Should I replace my tank with a tankless water heater?

It makes sense when you want endless hot water or need the floor space. A tankless heater has to be sized to your gas line or electric service, so we check both before we recommend one.

Do I need an expansion tank with a new water heater?

Most homes with a pressure-reducing valve or a check valve on the main water line need one. Without it, pressure builds each time the tank heats. We check your supply line and include the tank in the price if it's needed.

Can you replace a water heater in the attic?

Yes. Attic and closet installs take more care, and they need a pan with a drain line under the tank. We carry the old tank out and set the new one in the same spot.

Do you take the old water heater away?

Yes. Hauling off the old tank is part of every replacement we do.
