Water Heater Repair & Installation in Annapolis, MD
Tired of having to take a cold shower in the morning because your water heater isn't working as efficiently as it used to? Heidler, Inc. is your reliable Annapolis water heater repair team. Whether you need to repair your current water heater or replace a failing unit, we have you covered.
Common Water Heater Problems: What's Causing Your Hot Water Issues?
When your water heater starts to show signs of trouble, the problem is often traced to one of two causes. **Sediment buildup** is one of the most common causes of water heater problems. It can decrease hot water flow and lead to tank corrosion. In many cases, sediment can be flushed out — we recommend yearly flushing to keep your tank free of abrasive elements.
**Faulty parts** are the other frequent culprit. If you have an electric water heater, a faulty thermostat or a tripped breaker can cause problems. If you have a gas unit, the pilot light may go out, resulting in little or no hot water.
The age of your water heater can also affect its efficiency. Traditional water heaters last 7–10 years. Tankless water heaters have a longer lifespan at 15–20 years; these units also tend to have longer manufacturer warranties. Regular maintenance and good water quality go a long way in extending the life of your water heater.

Water Heater Repair vs. Replacement: Which Option Is Right for You?
Not sure if your water heater should be repaired or replaced? Contact us for a diagnosis, and we will let you know your options. The age and condition of your water heater are some of the factors to take into consideration. If your water heater is close to 10 years old and exhibiting frequent problems, water heater replacement may be the more cost-effective option.
While replacing your water heater involves a higher initial investment, you can actually save more down the road with a new unit installed. New water heaters are 20 percent more efficient than older units. This helps cut down on your energy bill, keeping it at a reasonable rate. If your water heater is only a few years old and has only a minor problem, repairing it may be best.
We serve homeowners throughout Anne Arundel County — including Severna Park, Arnold, Edgewater, and the surrounding communities. Help your water heater last longer by installing a water softener in your home.

Know the warning signs
When to Call for Water Heater Repair & Installation
Water Runs Cold or Lukewarm
A failed thermostat, tripped breaker, or dead pilot light will leave you short on hot water. Most are straightforward repairs when caught early.
Rumbling or Popping From the Tank
That noise is water boiling under a layer of hardened sediment. It kills efficiency and corrodes the tank from the inside out.
Rusty or Discolored Hot Water
UrgentBrown or metallic-tasting hot water usually means the tank lining or anode rod has failed. Replacement is often the only real fix.
Water Pooling Around the Base
UrgentA leaking tank does not repair itself and can flood a finished basement without warning. Shut off the supply and call immediately.

Water Heater Repair & Installation FAQs
How long does a water heater last?
Traditional water heaters last 7–10 years. Tankless water heaters have a longer lifespan at 15–20 years, and these units also tend to have longer manufacturer warranties. Regular maintenance and good water quality go a long way in extending the life of your water heater.
Should I repair or replace my water heater?
The age and condition of the unit decide it. If your water heater is close to 10 years old and exhibiting frequent problems, replacement is usually the more cost-effective option. If it's only a few years old with a minor fault and inexpensive parts, repairing it and scheduling regular maintenance is the better call.
Is a new water heater really more efficient?
Yes — new water heaters are about 20 percent more efficient than older units. While replacement involves a higher initial investment, that efficiency helps cut down your energy bill and you can save more down the road with a new unit installed.
Why should I flush my water heater every year?
Sediment settles and hardens at the bottom of the tank, decreasing hot water flow and leading to tank corrosion. In many cases sediment can be flushed out, which is why we recommend yearly flushing to keep your tank free of abrasive elements.
Would a water softener help my water heater last longer?
It can. Hard water accelerates scale buildup inside the tank, which is exactly what shortens its life. Many Anne Arundel County homes benefit from a [water softener](/water-softeners) for that reason.
I have no hot water at all — can you come out today?
In most cases, yes. We offer same-day service and emergency response across Annapolis and Anne Arundel County. Call (410) 268-7191 and we'll get you on the schedule.
