Understanding Tankless Water Heaters
When it comes to choosing a new water heater for your home, a tankless water heater can be an excellent choice. Not only do they provide hot water on demand, but they also come with several benefits over traditional tank-based models.
What are the benefits of a tankless water heater?
One of the biggest benefits of a tankless water heater is their energy efficiency. Unlike traditional tank-based heaters, which heat and store water continuously, tankless models only heat water as it is needed. This means they can save energy and reduce your utility bills.
In addition, tankless water heaters are more compact and take up less space than traditional tank-based models. They are also more durable and have a longer lifespan, which can save you money in the long run.
How do tankless water heaters work?
When you turn on a hot water faucet or appliance, tankless water heaters use an internal heating element or a gas burner to heat the water as it flows through the unit. This means that there is no need for a storage tank, which is why they are sometimes called on-demand water heaters.
As soon as you turn off the faucet or appliance, the tankless water heater stops heating water, which can save energy and reduce your utility bills.
Why are tankless water heaters popular?
Aside from their energy efficiency and compact size, tankless water heaters are popular because they can provide hot water on demand. This means you won't run out of hot water, even if you have multiple people using hot water at the same time.
Tankless water heaters are also more environmentally friendly than traditional tank-based models because they use less energy and produce less waste.
Are all tankless water heaters energy efficient?
While most tankless water heaters are more energy efficient than traditional tank-based models, not all tankless water heaters are created equal. Some models are more energy efficient than others, so it's important to choose a model with a high energy efficiency rating.
When selecting a tankless water heater, look for models with an Energy Star rating. These models meet strict energy efficiency guidelines set by the US Environmental Protection Agency (EPA) and can help you save on your utility bills.
Summary
In summary, tankless water heaters provide several benefits over traditional tank-based models, including energy efficiency, compact size, and on-demand hot water. When selecting a tankless water heater, look for models with a high energy efficiency rating and an Energy Star certification to help you save money on your utility bills.
Factors to Consider When Choosing a Tankless Water Heater
Choosing the best tankless water heater for your home can seem like a daunting task, but it doesn't have to be. There are several key factors to consider, which we'll outline below to help you make an informed decision based on your household's specific needs.
Household Size and Hot Water Demand
One of the most important factors to consider when choosing a tankless water heater is your household's size and hot water demand. The larger your household, the higher the hot water demand will be. To ensure you choose a tankless water heater that can meet your needs, you'll need to determine the appropriate flow rate, measured in gallons per minute (GPM).
Generally, a flow rate of 2-5 GPM is suitable for a small household, while a larger household with higher hot water demand may require a flow rate of 7-10 GPM or more.
Fuel Type
Tankless water heaters are available in electric, natural gas, and propane fuel types. Electric tankless water heaters are more energy-efficient but have a lower flow rate, making them better suited for smaller households with lower hot water demand. Natural gas and propane tankless water heaters have a higher flow rate, making them suitable for larger households with higher hot water demand, but they may have higher installation costs and require venting.
Energy Efficiency Ratings
When considering a tankless water heater, pay attention to its energy efficiency rating. The higher the rating, the more energy-efficient the unit will be, resulting in lower monthly energy bills. Look for units with an Energy Factor (EF) rating of at least 0.82 for electric models and a Uniform Energy Factor (UEF) rating of at least 0.87 for gas models.
Installation Costs and Requirements
Installation costs and requirements can vary depending on the type and model of the tankless water heater you choose. Electric models are generally easier to install and have lower installation costs, while natural gas and propane models may require professional installation and venting, resulting in higher installation costs. It's important to consider your budget and the installation requirements before making a final decision.
Warranty
When choosing a tankless water heater, consider the warranty offered by the manufacturer. A longer warranty period can provide peace of mind and protection against unexpected repairs or replacement costs. Look for a warranty period of at least 10 years for the heat exchanger and at least 5 years for other components.
By taking these factors into account, you can choose the best tankless water heater for your home that provides reliable hot water, energy efficiency, and cost-effectiveness.
