How Do Tankless Water Heaters Work?

If you’re thinking about replacing your water heater, you’ve likely come across tankless water heaters. Those who have switched praise their energy efficiency and report saving money on utility bills while still enjoying plenty of reliable hot water. 

So what makes one of these appliances different from a traditional stainless steel water heater? How do tankless water heaters work? Keep reading to learn whether a tankless water heater is the right choice for your home. 

A Simple Guide to Tankless Water Heaters 

A traditional or standard water heater with a tank keeps a supply of water heated at all times. When you shower, wash dishes, or do the laundry, the hot water comes from the tank already hot; the supply automatically replenishes.

Tankless water heaters work on demand. Instead of storing water, the unit connects to a water supply and instantly heats the water when you turn on the tap. Most units can heat between two and five gallons of water per minute. 

You can choose from two types of tankless water heaters: gas or electric. Gas water heaters have a gas burner that warms up the water, while electric tankless water heaters have electrical resistance heating coils. In either case, you can enjoy a practically limitless supply of hot water when you need it. In other words, even if the whole family takes showers and you run the dishwasher, you’ll still have plenty of hot water without waiting for the tank to refill.

The Pros and Cons of Tankless Water Heaters 

Energy efficiency is the primary advantage of switching to a tankless water heater. Standard water heaters use a significant amount of energy to keep the water in the tank hot, increasing operational costs. Tankless models only use energy on demand, which can slash your costs. 

Condensing tankless water heaters save even more energy since they capture and cool what would otherwise be wasted heat. Instead of venting the extra heat that comes from rapidly warming the water, the heat goes back into the unit, further reducing the amount of power consumed. 

Tankless water heaters also save space. Instead of taking up space on the floor with a tank, the wall-mounted units can fit into small spaces. They also last up to 20 years, compared to the average 12-year lifespan of a standard water heater. 

However, because these units can only heat so much water per minute, it’s critical to calculate the flow rate (how much hot water your home needs each day) accurately. Underestimating your hot water needs can mean dealing with the inconvenience of not having enough hot water. Some homeowners overcome this by installing multiple units to meet demand, but this means more expense.

Understanding the Importance of Water Heater Services 

Water heater services shouldn’t just be another item on the maintenance list for your home. They are what stands between you and the cold shock of the winter that you would be faced with if it fails. These water heater services involve a suite of actions that are designed to make sure that your water heater is thriving throughout the cool winter. 

The Pillars of Water Heater Health 

Before you run into issues from the cold, here are some of the essential heating services that will help keep your water heater in top condition. It will make sure that you never have to face the cold unprepared. 

  • Inspection and Maintenance
  • Tank Flushing
  • Insulation Checks
  • Emergency Repair Preparedness


As winter tightens its grip, your demand for a hot shower or a warm house doesn’t take a break. The silent yet steadfast water heater is probably working double time to meet all of your needs. However, without a watchful eye, it can falter when it’s needed most. Regular water heater services will give you peace of mind.

  • Detect and Protect: Catching sediment buildup and corrosion early can keep your water heater from becoming an energy hog or a breakdown statistic.
  • Efficiency Is Key: Consistent water heater services ensure each component sings in harmony, offering you hot water without a hitch.
  • Crisis Aversion: Professional eyes decipher the small clues that prevent the big problems, safeguarding your winter comfort.

In the heart of winter, knowing your water heater has been meticulously inspected and maintained can be the difference between a season of warmth and a cold surprise. Regular water heater services are your best defense against the unseen, ensuring reliability when the mercury dips.

Tank Flushing

Winter’s chill can be a trial for your water heater, but it’s nothing a good tank flush can’t fix for you. Over time, the unseen sediment that travels through the water will end up settling at the bottom, just like uninvited guests. It will result in compromising the warmth of your water. Flushing these away is like setting your water heater free to serve you better.

  • Clear the Clutter: Sediment may be out of sight at the bottom of your tank, but it shouldn’t be out of mind. Removing it means your water heats up efficiently.
  • Pre-Winter Prep: A little bit of prevention before winter sets in can ensure your water heater doesn’t falter when you’re reaching for that hot tap.
  • Long-Term Love: Regular tank flushing is the unsung hero that extends the life of your water heater, ensuring many more winters of faithful service.

With the tank cleared and the water flowing freely, your water heater is primed to face the coldest days. Tank flushing is a simple step in water heater services that reaps big rewards, keeping you cozy all season long. 

Insulation Checks

When the outside world turns into a winter wonderland, the last thing you want is the cold sneaking into your home through the nooks and crannies of your water heating system. Proper insulation is like a warm blanket for your pipes and water heater, keeping the heat where it belongs.

  • Wrap It Up: Inspect and snugly insulate pipes to keep the water temperature consistent from the heater to tap.
  • Gap Check: Look for leaks in the insulation—it’s like finding a window cracked open in a blizzard.
  • Pre-Winter Tune-Up: Address insulation issues before the cold sets in to lock in the heat and lock out the frost.

Closing out these checks before the winter sets in not only keeps your showers hot but also keeps your heating bills from rising. A well-insulated water heater is a fortress against the cold, ensuring you stay warm inside when it’s chilly outside.

Emergency Repair Preparedness

Winter’s chill is relentless, and even some of the best water heaters out there can fall to the pressure that winter puts on them. Being prepared for the unexpected means you will never have to face the cold shoulder of a broken water heater when you need it most.

  • Quick Fix: Ensure you have a plan set in place for a rapid response to leaks and breaks so you can prevent ongoing issues if your system fails.
  • Element Check: Regularly test the heating elements and your thermostats to avoid the icy surprise of a cold shower.
  • Seasonal Readiness: A winter-ready water heater is one that’s been checked for all common cold-weather issues.

Signs That It’s Time to Replace Your Water Heater

A water heater typically lasts for several years, but it can become worn out over time due to lack of maintenance or wear and tear. Before your water heater fails completely, it will most likely give some signs that there is a problem. If you know what to look out for, you will know when it’s time to contact a heating Northampton contractor and get a new water heater.

You Don’t Have Enough Hot Water

Sediment in the water heater tank can keep water away from the heat source. If your shower starts out hot and then turns cold before you’re finished, or if you and other members of your family have to wait a while between showers so that each person has enough hot water, you may have to buy a new water heater.

You See Rust in the Water

A water heater tank can rust on the inside, and that rust can get into the water. If water that comes out of a faucet or showerhead has a rusty color, that is a telltale sign that it’s time for a new water heater. If you don’t replace it soon, you may have an even bigger problem on your hands.

The Water Heater Leaks

Rust can eventually cause a water heater tank to leak. That can cause water to flood your basement or utility room. Water can cause major damage to your home’s structure, including mold. It may also damage or destroy your furniture, flooring, electronics, and other belongings.

You Hear Unusual Sounds

Strange noises can be a sign that sediment has accumulated in the water heater tank. The tank may also have cracks or holes, which means that it may leak if you don’t have the water heater replaced soon.
