The Benefits of Upgrading to a Tankless Water Heater

Traditional tank water heaters have been providing reliable hot water in homes for decades, but they aren't the only option. More homeowners are considering tankless water heaters when it's time to replace an aging system or improve the way their home produces hot water.

Instead of storing and continuously heating a large tank of water, a tankless water heater heats water as it is needed. For the right household, that can mean greater efficiency, a more consistent supply of hot water, additional usable space, and a longer equipment lifespan.

At Loyal Plumbing, Heating and Cooling, we help homeowners throughout Rapid City and surrounding Black Hills communities compare traditional and tankless water heaters. If you're wondering whether going tankless makes sense for your home, here are some of the most important benefits and considerations.

How Does a Tankless Water Heater Work?

A traditional water heater stores heated water inside a tank so it's ready when someone turns on a faucet, starts the dishwasher, or takes a shower.

A tankless water heater works differently.

When you turn on a hot water fixture, cold water enters the tankless unit. The system activates and heats the water as it passes through the equipment. When the demand for hot water stops, the unit stops heating.

Because there isn't a large storage tank of water being kept hot throughout the day and night, tankless systems can reduce the standby energy losses associated with traditional storage water heaters.

1. Hot Water When You Need It

One of the biggest reasons homeowners consider tankless water heaters is the ability to produce hot water on demand.

With a traditional tank, your household has a limited amount of stored hot water available at any given time. If several people take showers one after another or multiple hot-water appliances operate simultaneously, the tank can eventually run out.

Once that happens, you have to wait for another tank of water to heat.

A properly sized tankless system continuously heats water while there is demand, which can make it a great option for households that frequently use large amounts of hot water.

However, tankless doesn't mean unlimited capacity. Every unit has a maximum flow rate. Proper sizing is critical to make sure the system can handle your household's expected hot water demand.

2. Improved Energy Efficiency

Traditional tank water heaters maintain a reservoir of hot water even when nobody is using it.

That means energy is periodically required to maintain the temperature of the stored water.

Tankless systems heat water only when there is demand. Eliminating the need to continuously maintain a tank of hot water can reduce unnecessary energy consumption.

Actual energy savings depend on several factors, including:

• Household hot water usage
• The efficiency of the equipment
• Fuel type
• Incoming water temperature
• System sizing
• Installation quality
• Maintenance

A professional evaluation can provide a more realistic picture of how a tankless system may perform in your particular home.

3. Tankless Water Heaters Take Up Less Space

A traditional water heater can take up a significant amount of floor space because it needs room for the storage tank.

Tankless water heaters are much more compact and are typically mounted on a wall.

Depending on your home's layout, eliminating a large water heater tank may free up valuable space in a utility room, basement, mechanical room, garage, or other area.

This can be particularly helpful in homes where storage and mechanical space are limited.

4. Tankless Systems Can Have a Long Service Life

Water heater replacement is an investment, so expected equipment life is an important consideration.

Traditional tank water heaters commonly have a shorter expected lifespan than well-maintained tankless systems.

Tankless water heaters can often provide many years of service when they are properly installed and maintained.

Actual lifespan depends on water quality, usage, equipment quality, installation, and how consistently the system receives maintenance.

Rather than looking only at the initial purchase price, homeowners should consider the expected long-term ownership costs when comparing water heater options.

5. You Don't Have a Large Storage Tank Full of Water

Traditional water heaters store many gallons of water inside a tank.

If that tank eventually corrodes or develops a significant leak, the surrounding area can potentially be exposed to a substantial amount of water.

Tankless water heaters eliminate the large storage tank.

That doesn't mean tankless equipment can never leak. Connections, valves, heat exchangers, and other components can still develop problems. However, you aren't storing a large volume of heated water inside a tank around the clock.

6. Consistent Hot Water for Busy Households

Hot water demand can add up quickly in a busy home.

Morning showers, laundry, dishwashing, baths, and other household activities can all require hot water within a relatively short period.

A properly selected tankless system can be particularly attractive for families that frequently exhaust the capacity of a traditional water heater.

The important phrase is properly selected.

If the unit isn't sized to meet your home's peak demand, running several fixtures simultaneously may exceed its capacity.

That's why professional sizing should be part of any tankless water heater installation.

7. Modern Temperature Control

Many modern tankless water heaters provide precise electronic temperature controls that allow the system to maintain a specific hot water setting.

Depending on the equipment selected, homeowners may also have access to additional controls, monitoring capabilities, or system information.

The exact features vary by manufacturer and model, so it is worth comparing equipment based on more than just price.

Is a Tankless Water Heater Right for Every Home?

No water heating system is automatically the best option for every household.

Tankless water heaters offer several advantages, but homeowners should also consider installation requirements, household demand, available utilities, water quality, and upfront cost.

Some homes can transition to tankless relatively easily. Others may require modifications to accommodate the new equipment.

Depending on the system, installation considerations can include:

• Gas line capacity
• Electrical requirements
• Venting
• Equipment location
• Incoming water temperature
• Peak household hot water demand
• Existing plumbing configuration

These factors should be evaluated before choosing a specific unit.

Proper Tankless Water Heater Sizing Is Important

Choosing a tankless water heater isn't simply a matter of selecting the biggest unit available.

The system should be sized according to your household's hot water requirements and the temperature rise needed to deliver hot water at the desired temperature.

A plumber may consider how many hot water fixtures could operate simultaneously, such as:

• Showers
• Bathroom faucets
• Kitchen faucets
• Dishwashers
• Washing machines
• Bathtubs

Incoming groundwater temperature also matters. The colder the incoming water, the more work the system must do to bring it to the desired hot water temperature.

This is particularly important when selecting equipment for homes in South Dakota's colder climate.

Water Quality Matters With Tankless Systems

Minerals in water can accumulate inside plumbing equipment over time, and tankless water heaters are no exception.

Scale buildup inside the heat exchanger can affect performance and potentially shorten equipment life if it isn't addressed.

That's why water quality should be considered when installing and maintaining a tankless system.

Homes with harder water may require more attention to preventative maintenance. Depending on your home's water conditions, additional water treatment options may also be worth discussing.

Tankless Water Heaters Still Need Maintenance

Tankless does not mean maintenance-free.

Like any important piece of home equipment, regular maintenance helps keep the system operating properly.

Depending on the equipment and water conditions, maintenance may include inspecting the system, checking connections, evaluating operation, cleaning components, and flushing mineral buildup from the heat exchanger when necessary.

Following the manufacturer's recommended maintenance schedule can help protect performance and equipment life.

Tankless vs. Traditional Water Heaters

Choosing between tankless and traditional water heating ultimately comes down to your household's needs and priorities.

A traditional tank water heater may offer a lower upfront installation cost and straightforward replacement in homes already configured for one.

A tankless system may make more sense when you value energy efficiency, additional space, longer equipment life, and continuous hot water production.

Consider factors such as:

• Initial installation cost
• Expected energy usage
• Household size
• Peak hot water demand
• Available installation space
• Current water heater condition
• Long-term maintenance
• Expected time in the home

Looking at the complete picture can help you make a better decision than simply comparing the purchase price of two water heaters.

When Should You Consider Replacing Your Current Water Heater?

You don't necessarily need to wait until your existing water heater completely fails before considering replacement.

If your current system is getting older, replacement planning gives you time to compare your options instead of making a rushed decision after losing hot water.

Signs that your water heater may deserve professional attention include:

• Running out of hot water more frequently
• Inconsistent water temperatures
• Water around the unit
• Visible corrosion
• Unusual noises
• Discolored hot water
• Increasing repair frequency
• A system that no longer meets your household's needs

A professional inspection can help determine whether repairing the existing system still makes sense or whether it's time to consider replacement.

Should You Upgrade to a Tankless Water Heater?

If your existing water heater is approaching replacement and you're interested in improving efficiency or changing the way your home produces hot water, it's a good time to explore tankless options.

The right system should be selected based on your home—not simply because tankless technology is newer.

Household demand, fuel source, installation requirements, water quality, budget, and long-term plans should all factor into the decision.

Working with an experienced plumber can help you understand those differences and select a system that is appropriately sized for your home.
