What are the key Differences between Standard Tankless Water Heaters? When choosing a water heater for your home, it’s crucial to understand your options. Two of the most popular types are standard (or traditional) water heaters and tankless water heaters. Each comes with its advantages and disadvantages, so it’s about finding the one that best suits your needs.
A standard water heater works by storing and preheating up to 50 gallons of water in a tank. Once the water is used, the tank is refilled and reheated. This method, while effective, may seem time-consuming for some homeowners. Tankless water heaters, on the other hand, heat water on-demand, eliminating the need to wait for a storage tank to fill and heat up.
This is the fundamental difference between standard and tankless water heaters, but the differences don’t stop there. Let’s delve deeper into the distinct advantages of each system.
Tankless Water Heater Pros and Cons
Tankless water heaters, often referred to as “on-demand” water heaters, warm up water directly without using a storage tank. When a hot water tap is turned on, cold water flows through a pipe into the unit, where either an electric element or gas burner heats the water. This means you’ll have a constant supply of hot water whenever you need it.
Here are the key advantages of tankless water heaters:
Longer Lifecycle: Unlike standard water heaters, which typically last 10-15 years, tankless models can last over 20 years. Some higher-end models may even function up to 30 years with proper maintenance.
Cost-Savings: Tankless water heaters are more energy-efficient, with potential savings of up to 34%. If the unit is gas-powered, you could save at least $100 every year, with savings increasing based on usage.
Space-Saving Design: With their compact design, tankless water heaters take up less space than standard ones. They can be mounted on outer walls or tucked away in tight corners, freeing up valuable space in your home.
On-Demand Water: Enjoy hot water whenever you need it. There’s no waiting for a tank to fill up and heat. Depending on the unit, tankless water heaters can deliver up to 3-5 gallons of hot water per minute.
Advantages of Standard Water Heaters/disadvantage of tankless water heater
Standard, or traditional, water heaters operate by storing water in a tank and consistently heating it to maintain a set temperature. They’re straightforward, reliable, and have been the go-to option for homeowners for decades. Here are the key advantages of choosing a traditional water heater:
Low Initial Cost: Traditional water heaters are generally less expensive to purchase and install than their tankless counterparts.
Simplicity and Low-Cost Maintenance: Standard water heaters have fewer parts and a simpler design, making them easier and less costly to maintain and repair.
Easy Replacement: If a traditional water heater fails, it’s typically straightforward to replace with a similar unit, requiring minimal changes to plumbing or gas lines.
Here are some further considerations that may help you decide:
Size of the Household: A larger household, where multiple hot water appliances might be used simultaneously, could benefit more from a tankless water heater’s ability to deliver a constant supply of hot water. On the other hand, a smaller household with less simultaneous hot water usage might be perfectly served by a standard water heater.
Energy Efficiency: If reducing your carbon footprint is a priority, a tankless water heater can be a great choice. They are more energy-efficient, as they only heat water when required, leading to less wasted energy.
Future Savings: While a tankless water heater may require a higher upfront cost, you may recoup these costs over time due to lower energy bills and the longer lifespan of the unit. However, if the upfront cost is a major concern, a traditional water heater might be a more cost-effective choice initially.
Installation Considerations: Before choosing a tankless water heater, it’s important to consider the costs of installation, which can be more complex and costly than standard models. For instance, if you’re switching from a standard water heater to a tankless model, additional costs may include upgrading your home’s electrical system or gas pipeline to handle the new unit.
Lastly, it’s important to remember that every home and every family has unique requirements. What works best for one home may not be ideal for another. A professional plumber can guide you through the process and help you choose the water heater that’s best suited to your needs.
While tankless water heaters may have a higher initial cost and may be more expensive to maintain, they can save you money over their lifespan due to energy efficiency and longevity. They’re also ideal for larger families or high-demand households, as they can deliver consistent hot water without making anyone wait.
