Tankless Water Heater: The Efficient Solution for Hot Water Needs

Tankless Water Heater: The Efficient Solution for Hot Water Needs

By Contractors.com Team March 18, 2024

Are you considering a new water heater? A tankless water heater might be just what you're looking for. These units heat water on demand, ensuring you always have hot water without the energy and cost of heating a large tank continuously. They come in both electric and gas models. Electric ones tend to be cheaper initially but can be more expensive to operate. Conversely, gas models might have a higher upfront cost but usually offer better energy efficiency, potentially lowering your energy bills over time.

To find the perfect tankless water heater, assess your household's hot water needs, focusing on the size and flow rate to meet your demand. Also, the energy efficiency, warranty, and total cost of the unit must be taken into account. This way, you'll make an informed decision that balances your immediate needs and long-term savings.

Basics of Tankless Water Heaters

These high-tech devices are becoming increasingly popular for their energy efficiency and space-saving design. In this section, we'll cover the basics, including how they work, different types, and their advantages over traditional water heaters.

How They Work

Unlike traditional models that store hot water in a tank, they offer a modern twist by heating water directly as it flows through the unit. When you open a hot water tap, cold water enters the unit, where either an electric element or gas burner warms it up before it heads to your faucet or shower. This method means you can enjoy a continuous supply of hot water, perfect for large families or any home with a high demand for hot water.

Types of Tankless Water Heaters

They usually come in two primary types: electric and gas. Electric models are usually more affordable and simpler to install but might be less powerful and pricier in the long run. On the other hand, gas heaters tend to be more expensive initially and need professional installation, but they offer a higher hot water output and are typically more energy-efficient.

Installation and Maintenance

Installation Process

Installing a tankless water heater effectively enhances your home's energy efficiency and saves space. Prior to installation, evaluating the designated area is crucial. Hiring a professional plumber ensures the optimal placement of your heater, taking into account the fuel source, ventilation requirements, and how close it is to where you'll need hot water. Following the assessment, your plumber will remove the existing water heater and set up the new tankless unit. 

Maintenance Requirements

Proper maintenance is essential for extending the lifespan of your heater. This includes routine tasks such as inspections, cleaning, and replacing parts as needed. Regularly cleaning your unit with 2.5 gallons of undiluted white vinegar is advised, as it's a safer alternative to chemical cleaners. Moreover, an annual flush of the system helps eliminate mineral buildup, keeping your water heater in top condition.

Common Issues and Troubleshooting

If you face any problems with your heater, it's best to contact a professional plumber for troubleshooting and repairs. Common issues include a lack of hot water, reduced water pressure, and error codes displayed by the unit. Frequently, these problems can stem from insufficient gas or electricity supply, so checking the connections for proper function is crucial. Moreover, a lack of hot water could be due to a clogged filter or a faulty thermostat.

Energy Efficiency and Environmental Impact

Energy Savings

They excel in energy efficiency compared to traditional storage tank models by heating water only on demand, eliminating the need to reheat water continuously. This reduction in energy use can lead to significant savings on your energy bills. The Department of Energy notes tankless water heaters can be up to 34% more energy-efficient for homes using 41 gallons or less of hot water daily. Even for homes with higher hot water consumption, savings can reach up to 14%.

Environmental Benefits

These heaters offer notable environmental advantages by using less energy, leading to reduced greenhouse gas emissions. They also boast a longer lifespan compared to traditional storage tank models, generating less waste over time. Moreover, when a tankless water heater reaches the end of its life, it can be recycled, minimizing its environmental footprint.

Rebates and Incentives

Utility companies and government organizations frequently provide rebates and incentives to homeowners installing tankless water heaters, helping to offset the initial cost. Moreover, these water heaters may also qualify for federal tax credits, further reducing installation expenses.

Selecting the right heater involves considering several key factors. This section will cover essential aspects like size and capacity, fuel types, and how to compare different brands and models.

Size and Capacity Considerations

When choosing a tankless water heater, size and capacity are crucial to ensure it efficiently meets your household's hot water needs. Select a unit that provides enough hot water without using excessive energy.

To find the right size for your home, factor in your household size and the simultaneous use of hot water appliances. Here are some guidelines:

  • Small households (1-2 people): 27 kW or less
  • Medium households (3-4 people): 27-40 kW
  • Large households (5 or more people): 40 kW or more

Fuel Types

Fuel type is a key factor in choosing a tankless water heater, with electric and gas-powered models being the most common.

Electric ones cost less to buy and install, offer higher energy efficiency, and need less maintenance. They're ideal for smaller households with moderate hot water needs. On the other hand, gas-powered models, though pricier initially and to install, cater well to larger households with high hot water demand, providing hot water at a faster flow rate.

Brand and Model Comparisons

Choosing the right one involves comparing brands and models to find one that suits your needs best. Focus on reliability, energy efficiency, and a solid warranty. Brands like Rheem, Rinnai, and Navien offer a range of models with varying features and specifications. Carefully review these options to make an informed decision.
