The luxury of turning on a faucet and having hot water flow on demand is often taken for granted. A reliable hot water supply is more than just a convenience; it is a crucial aspect of our daily lives.

Whether you’re replacing your old water heater or building a new home, you have two main types to choose from: tankless and traditional. Each has its own set of benefits and drawbacks, so it’s important to understand which type suits your needs best.

What Are Tankless Water Heaters?

Tankless water heaters, often referred to as “on-demand” water heaters, heat water directly without the need for a storage tank. Tankless water heaters are outfitted with a series of components that work in harmony to provide hot water on demand. When you open a hot water tap, the cold water travels through a pipe into the unit.

Here, it encounters the heat exchanger. This is typically electrically powered or heated by gas and is triggered by the flow of water. The heat exchanger transfers its heat to the cold water, warming it to the desired temperature. This process is instantaneous, hence the term “on-demand water heater.”

Advantages of Tankless Water Heaters

Firstly, their energy efficiency is a standout feature. Since they only heat water when it is needed, they avoid the energy losses associated with traditional water heaters thereby saving on utility bills. They are also space-efficient, eliminating the need for a bulky storage tank and making them ideal for smaller homes or apartments.

Moreover, tankless water heaters provide an uninterrupted supply of hot water, ensuring that you never run out of hot water during a shower or when conducting multiple household chores simultaneously. This is in sharp contrast to traditional tank heaters, which can deplete their hot water supply.

Their longevity is another significant advantage. On average, tankless heaters have a longer lifespan than their traditional counterparts, often lasting up to 20 years with proper maintenance. This makes them a cost-effective investment in the long run.

Finally, the water quality from a tankless heater is generally superior as the water doesn’t sit in a tank potentially being exposed to rust and scale for extended periods.

Disadvantages of Tankless Water Heaters

To begin with, tankless water heaters have a higher initial cost compared to traditional tank heaters. This is due to the more complex components required for operation. They also require professional installation, which can further add to the cost.

In addition, while tankless water heaters offer endless hot water, their capacity is limited by the flow rate. This means that if you are running multiple appliances at once it’s possible to exceed the flow rate and cause your heater to shut off temporarily.

Finally, tankless water heaters require more frequent maintenance because of their complex design. Fortunately, the pros at Apollo Plumbing, Heating & Air Conditioning make scheduling tankless water heater maintenance a breeze. We work 24/7, so we are available on your schedule.

What Are Traditional Water Heaters?

Traditional water heaters use an insulated storage tank to store hot water until it is needed. They typically feature two components: a cold water inlet valve and a hot water outlet pipe. When the hot water tap is opened in the home, cold water travels into the tank and is heated by an electric element or gas burner. The warm water then rises to the top of the tank where it can be drawn off for use.

Advantages of Traditional Water Heaters

The main advantage of traditional water heaters is their cost—they are significantly cheaper to purchase and install than tankless models. Their simple design also means that they require less maintenance, which could save homeowners a little bit of money and hassle.

Secondly, it’s easier to predict their hot water yield. Since the tank has a given capacity, you can estimate your hot water needs in advance and select the appropriate-sized tank. It’s also not typically a problem to do two tasks at once that require hot water without compromising either, like doing laundry and taking a shower. You also get a feel for your water heater once you’ve had it for a while, so it’s easier for you to estimate your tank’s limits and plan accordingly.

Thirdly, the water temperature is much easier to regulate with traditional tank heaters as it’s simply a matter of adjusting the thermostat. Regulating the max water heater temperature is crucial in homes with children or elderly people to prevent injuries. With tankless models, you must adjust both the flow rate and temperature setting for precise control.

Disadvantages of Traditional Water Heaters

While traditional water heaters are cost-effective, they have a lower energy efficiency than tankless models. As the hot water cools off in the tank, it must be reheated continuously to maintain its temperature; you’re essentially paying to heat water that’s just sitting there. This leads to higher electricity bills and wasted energy over time.

Moreover, traditional water heaters require more space because of their bulky storage tanks, making them a less attractive option for small homes. Also, because of their design, traditional water heaters are prone to rust and scale build-up over time, which can adversely affect the quality of hot water. Finally, there’s always a possibility that the tank could leak, which could cause damage to your walls and floors.

So, Which One Should You Choose?

Both tankless and traditional water heaters have their own benefits and drawbacks, so it’s important to do your research before deciding which one is right for you. If cost is a key factor, then a traditional water heater might be more suitable. However, if energy efficiency and an uninterrupted supply of hot water are important considerations, then a tankless water heater system is probably the better choice. Either way, it’s important to keep in mind that both models require professional installation and regular maintenance for optimal performance.

Also, the availability of gas mains will play a role in your decision. If you have access to natural gas, then a gas-powered tankless water heater can provide an even greater energy efficiency advantage over its electric counterparts. But if there’s no gas supply at your home, then electric tankless and traditional water heaters are both viable options.

Ultimately, the choice of water heater depends on your budget, hot water needs, and energy requirements. By weighing all these factors and choosing carefully, you can enjoy the very best in hot water performance for years to come.
