Welcome to Airtek's expert guide on how to install a tankless water heater, a journey that promises to lead you to a haven of endless hot water. With an emphasis on efficiency, cost-saving, and providing a seamless supply of hot water, tankless water heaters stand out as a superior choice for homeowners. But how do you embark on this transformative journey? Let's delve into the intricacies of installation, armed with insights and guidance from Airtek's seasoned professionals.

Understanding Tankless Water Heaters

Before diving into the installation process, let's demystify what tankless water heaters are and how they stand apart from their tanked predecessors. At its core, a tankless water heater, also known as an on-demand water heater, heats water directly without the use of a storage tank. When a hot water tap is turned on, cold water travels through a pipe into the unit, where a gas burner or electric element heats the water. This means you're not storing a massive tank of hot water that can run out; instead, you get hot water when you need it, for as long as you need it.

Key Advantages:

• Energy Efficiency: Unlike traditional water heaters that heat and reheat water at a set temperature regardless of your needs, tankless heaters only use energy when you turn on the tap. This can lead to significant savings on your energy bill.
• Space Saving: With no need for a bulky tank, tankless heaters are compact and can be installed in smaller spaces, freeing up room for other uses.
• Longevity: Tankless water heaters typically have a longer lifespan than traditional water heaters, with many models lasting more than 20 years.

Considerations:

• Upfront Cost: The initial investment for a tankless water heater can be higher than that of a traditional tank heater. However, the energy savings and longer lifespan can offset this over time.
• Installation Requirements: Installing a tankless water heater involves dealing with gas lines, venting systems, and electrical work, making it a more complex process that might require professional assistance.

Choosing the Right Tankless Water Heater

Selecting the perfect tankless water heater involves more than just picking any model off the shelf. It requires careful consideration of your household's specific needs, the fuel type, and the size of the unit. Here's how to navigate these choices to ensure you get the most efficient and suitable system for your home.

Fuel Type:

• Electric: Ideal for smaller applications, such as a single bathroom or as a booster for appliances. Requires adequate electrical capacity to support the unit's demands.
• Gas: Suitable for whole-house applications, offering higher flow rates. It's important to consider the availability of natural gas or propane and the need for proper venting.

Size and Flow Rate:

Determining the right size involves calculating the flow rate and temperature rise you'll need. The flow rate (measured in gallons per minute, GPM) depends on how many fixtures you want to run simultaneously. Temperature rise is the difference between the ground water temperature and your desired output temperature.

• Calculate Your Needs: Add up the flow rates of all fixtures you plan to run at the same time (e.g., shower, dishwasher, kitchen sink) to get your required flow rate.
• Consider Peak Demand: Think about times when demand will be highest and choose a model that can handle this peak.

Brand and Model:

• With brands like Gree and ATK AirTek highlighted by Airtek, you're assured quality and reliability. Look for models with high SEER2 and HSPF2 ratings for the best efficiency.
• Check reviews and product specifications to ensure the model meets your needs.

Government Rebates and Energy Efficiency:
