A Comprehensive Look at Its Advantages and Disadvantages
Tankless water heaters are becoming an increasingly popular choice for homeowners in the United States due to their many benefits. One type of tankless water heater is the outdoor unit, which is installed outside the home rather than indoors. In this article, we will explore the advantages and disadvantages of outdoor tankless water heaters.
Advantages Of An Outdoor Tankless Water Heater
Cost-Effective Operation:
Outdoor tankless water heaters are more energy-efficient than traditional tank-based models, resulting in lower utility bills and long-term cost savings.
Uninterrupted Supply of Hot Water:
These units provide an uninterrupted supply of hot water, meaning you'll never have to worry about running out of hot water during a shower or while doing laundry.
On-Demand Hot Water:
Tankless water heaters only heat water as needed, which means you'll never waste energy heating water that you don't need.
Longer Lifespan:
Outdoor tankless water heaters have a longer lifespan than traditional tank-based models, lasting up to 20 years with proper maintenance.
Space-Saving:
These units are compact and space-saving, making them ideal for smaller homes and condos.
Easy Installation:
Outdoor tankless water heaters are easy to install and require minimal plumbing and electrical work.
Environmentally Friendly:
Tankless water heaters are environmentally friendly, producing fewer greenhouse gases and reducing your carbon footprint.
Reduced Energy Consumption:
Tankless water heaters are more energy-efficient than traditional tank-based models, reducing your energy consumption and saving you money.
Disadvantages Of An Outdoor Tankless Water Heater
Limited Flow Rate:
Tankless water heaters have a limited flow rate, which means they may not be able to provide enough hot water for larger households or homes with high hot water demands. It's important to choose the right size unit for your home's hot water needs.
Potential For Freezing:
Outdoor tankless water heaters can be susceptible to freezing in colder temperatures. It's important to properly winterize the unit to prevent damage.
Possibility Of Leaks:
While tankless water heaters generally have a lower risk of leaks compared to traditional tank water heaters, they are not completely immune. It's important to have your unit inspected regularly to prevent any potential leaks.
Installation Complexity:
Tankless water heaters have a more complex installation process compared to traditional tank water heaters. It's important to hire a professional installer to ensure proper installation.
Higher Gas Consumption:
Tankless water heaters may consume more gas than traditional tank water heaters, particularly during periods of high hot water demand.
Low Gallons Per Minute (GPM):
Tankless water heaters have a lower gallons per minute (GPM) rate compared to traditional tank water heaters, which can limit the amount of hot water available during high demand periods.
Temperature Fluctuations:
Tankless water heaters can experience fluctuations in water temperature, particularly when there is high hot water demand. This can result in inconsistent water temperatures during use.
Colder Water For Longer Showers:
Tankless water heaters may not be able to provide enough hot water for longer showers or baths, resulting in colder water towards the end of the shower.
Inefficient Energy Usage:
Tankless water heaters may not be as energy efficient as advertised if they are not properly sized and installed for your home's hot water needs.
Overall Higher Operating Costs:
Despite their potential for energy savings, tankless water heaters can have higher operating costs compared to traditional tank water heaters due to their initial cost, installation complexity, and maintenance needs.
Higher Energy Bills:
While tankless water heaters may help lower utility bills, they may also lead to higher gas bills due to increased gas consumption during periods of high hot water demand.
Limited Climate Adaptability:
Tankless water heaters may not perform as well in colder climates and may require additional winterization measures.
Poor Performance In Colder Climates:
Tankless water heaters may not be able to provide enough hot water during periods of high demand in colder climates, which can result in inconsistent water temperatures.
Need A Dedicated Venting System:
Tankless water heaters may require a dedicated venting system.
Despite these disadvantages, an outdoor tankless water heater can still be a good choice for certain situations, such as when indoor space is limited, or when the unit needs to be installed far away from the point of use. Proper installation, maintenance, and protection can help mitigate the disadvantages and prolong the lifespan of the unit.
Frequently Asked Question
What to Know About Tankless Water Heaters?
They provide hot water on demand and can save energy and money in the long run. There are two main types of tankless water heaters: electric and gas. The size and flow rate of the unit should be carefully considered to ensure it meets the household's hot water needs. Proper installation and maintenance are crucial to ensure the unit operates safely and efficiently. While there are several benefits to using a tankless water heater, there are also some disadvantages to consider, such as higher upfront costs and potential issues with hard water.
What is the best practices for installing a tankless water heater?
The best practices for installing a tankless water heater include proper planning and preparation, ensuring proper ventilation and combustion air supply, following the manufacturer's instructions and local codes, and using a licensed and experienced plumber or contractor. Other factors to consider include the location and size of the unit, the type of fuel or energy source, and the necessary safety features such as pressure relief valves and earthquake straps. Proper maintenance and regular inspections are also important for ensuring the continued safety and efficiency of the water heater.
How To Install A Tankless Water Heater Outside?
Installing a tankless water heater outside involves several steps, including selecting the appropriate location, installing the required piping and venting, and setting up the unit itself. It's important to note that the installation process can vary depending on the specific unit you have and local building codes, so it's always best to consult a professional if you're unsure about any aspect of the installation.
Costing of tankless water heater?
The cost of a tankless water heater can vary depending on several factors, including the brand, size, and model of the unit, as well as the cost of installation. On average, a tankless water heater can cost between $500 to $2,500 or more, with higher-end models costing upwards of $4,000. It is important to consider the long-term savings on energy bills that a tankless water heater can provide, as well as the potential costs of installation and maintenance. It is recommended to consult with a professional plumber or HVAC technician to determine the most cost-effective and efficient option for your specific needs.
What is the difference between the indoor and outdoor tankless water heater?
The main difference between indoor and outdoor tankless water heaters is their installation location. Indoor tankless water heaters are installed inside a home or building, typically in a utility room or closet. They require venting to the outside, either through a chimney or wall, to expel exhaust gases. Outdoor tankless water heaters, on the other hand, are installed outside the home or building, usually on a wall or mounted on the ground. They do not require venting since they release exhaust gases directly into the outside air. Additionally, outdoor models may have different features and components to withstand outdoor elements and weather conditions.
Fogatti outdoor tankless water heaters have numerous advantages such as cost-effective operation, lower utility bills, reduced maintenance costs, uninterrupted supply of hot water, longer lifespan, space-saving design, and reduced carbon footprint. However, there are also several disadvantages to consider, such as high initial cost, limited flow rate, potential for freezing, possibility of leaks, and limited climate adaptability. It is important to carefully evaluate your needs and circumstances before deciding whether an outdoor tankless water heater is the right choice for you. Proper installation, regular maintenance, and choosing the right unit for your specific needs can help maximize the benefits and minimize the drawbacks of an outdoor tankless water heater.
