Tankless water heaters are becoming an increasingly favored option for homeowners seeking to improve energy efficiency and save space. Unlike traditional water heaters, which store hot water in a tank, tankless units heat water on demand as it flows through the system. This heating method ensures that hot water is always available without the constant need to keep a water tank heated. At MoCo Plumbing, we specialize in the installation and maintenance of these systems, helping homeowners enjoy hot water and savings. We’ll cover the benefits of tankless water heaters, the installation process, and maintenance tips to help you decide.
What is a Tankless Water Heater?
A tankless water heater, also known as an on-demand water heater, is a modern appliance that heats water instantly when you turn on the faucet. This contrasts with conventional water heaters, which store large amounts of hot water in a tank. With a tankless unit, the water is heated only as it flows through the system, eliminating the need for a storage tank. You’ll never run out of hot water, and the system optimizes energy use by heating only when necessary.
Key Benefits of Tankless Water Heaters
Energy Efficiency
One of the crucial advantages of tankless water heaters is their energy efficiency. Traditional water heaters keep water hot constantly, which results in substantial energy loss due to standby heat loss. Tankless models, on the other hand, only heat water when you need it, diminishing energy consumption and lowering your utility bills. As a result, homeowners who switch to tankless technology often see a noticeable decrease in energy costs over time.
Endless Hot Water
A tankless water heater supplies an ongoing supply of hot water. Unlike traditional systems that may run out of hot water after a certain amount of usage, tankless units continuously heat water as long as it flows through the system. Whether running multiple showers, washing dishes, or filling a bathtub, you won’t have to worry about running out of hot water halfway through. This mainly benefits more extensive families or households with increased water usage.
Space Saving
Tankless water heaters are compact and take up much less space than traditional water heaters, which require large storage tanks. These smaller units can be installed in tight spaces, such as closets, utility rooms, or even on an exterior wall, saving valuable indoor space. This space-saving feature makes tankless water heaters an ideal option for homes with limited room or those looking to maximize storage areas. Additionally, because the unit is mounted on the wall, it keeps the floor clear and free of bulky equipment.
Long Lifespan
Tankless water heaters have a longer lifespan than traditional tank models. With proper maintenance, tankless units can last 20 years or better, while conventional water heaters generally only last 10-15 years. This extended lifespan makes them an excellent long-term investment, as homeowners will only need to replace the system occasionally. Proper care, including descaling and regular inspections, can help you get the most out of your tankless water heater and dodge costly repairs or replacements.
How Tankless Water Heaters Work
Tankless water heaters warm water as it passes through the unit, using electricity or natural gas. When you open a hot water tap, cold water enters the unit, quickly heated by either a gas burner or an electric element. This instant heating process stops the need for a storage tank and ensures that you have a steady hot water supply as long as you need it. The system is developed to maintain a constant water temperature so you won’t experience changes or sudden drops in hot water during use.
Heating Process and Energy Efficiency
The heating process in a tankless water heater is highly efficient because it only heats water when needed. This contrasts with traditional water heaters, which keep a large tank of water hot continuously, consuming energy even when no hot water is being used. By heating water on demand, tankless models reduce standby heat loss and energy waste, leading to greater efficiency and lower energy bills over time.
Benefits of On-Demand Hot Water
One of the main advantages of tankless water heaters is the ability to provide on-demand hot water without waiting for a tank to heat up. This ensures an endless supply of hot water, making it ideal for larger households or homes with high hot water demands. Additionally, since tankless units do not store water, they reduce the risk of water contamination or the buildup of bacteria that can occur in a traditional tank heater.
How to Install a Tankless Water Heater
Selecting the Right Size
To install a tankless water heater, you must select the right size for your household’s needs. You must consider factors like the number of bathrooms, appliances requiring hot water, and the water flow rate in your home. The right size unit will ensure adequate hot water capacity for your family’s usage. Installing a tankless water heater also requires professional assistance, as the system needs to be correctly connected to your home’s plumbing and electrical or gas lines.
Professional Installation
A professional installer will handle the necessary steps to ensure your unit works efficiently and safely. They’ll make any required adjustments to your plumbing system, such as adding new pipes or upgrading your gas line. Proper installation is essential to prevent future issues, such as water flow problems or inadequate heating performance. An experienced technician will also test the system after installation, ensuring it operates optimally before you use it.
Maintaining Your Tankless Water Heater
Descaling the Unit
Preserving your tankless water heater ensures it continues operating efficiently for years. One of the most critical maintenance tasks is descaling the unit, especially if you live in an area with hard water. Mineral buildup inside the system can cause the unit to overheat and reduce effectiveness. Regular descaling helps discourage this, keeping the system operating smoothly and extending its lifespan.
Cleaning the Filters
Another key maintenance undertaking is cleaning the filters regularly. Filters trap debris and prevent blockages in the water flow, but they can get clogged over time. Cleaning consistently or replacing the filters will assist in maintaining optimal water flow and prevent issues with water pressure. Additionally, flushing the system once a year helps remove any remaining sediment or mineral deposits, ensuring the heater works efficiently.
Regular Inspections
Schedule routine assessments with a professional plumber to keep your tankless water heater in top condition. They can check the unit for potential issues, such as leaks, wear and tear, or malfunctioning parts. A well-maintained unit will continue to operate efficiently, saving you money on repairs and keeping your hot water supply steady. By staying on top of maintenance, you’ll avoid unexpected breakdowns and ensure the longevity of your investment.
Troubleshooting Common Tankless Water Heater Problems
Low Water Pressure
Low water pressure is one of the most common issues with tankless water heaters. This can happen if the filters are blocked or there is a buildup of minerals or debris inside the system. If you notice a decrease in water pressure, try cleaning or replacing the filters and flushing the system. If the problem persists, contact an experienced plumber to inspect the unit and ensure everything is functioning properly.
Inconsistent Water Temperature
Another issue some homeowners need help with is consistent water temperature. This can happen if the unit is too small for the household’s needs or if the heating elements malfunction. If your tankless water heater struggles with temperature consistency, check the flow rate and confirm the unit is properly sized. A technician can also check for any internal issues causing the fluctuation.
Cost of Installing a Tankless Water Heater
The cost of installing a tankless water heater varies based on factors like model, installation complexity, and system upgrades. The upfront cost of a tankless unit is usually higher than a traditional water heater. However, the long-term savings on energy bills can make it a worthwhile investment. Over time, these savings can offset the initial expense. Additional expenses may arise for gas-powered units if gas line upgrades are required. Although the initial investment may seem steep, the energy efficiency and durability over time can help balance the cost.
Factors Affecting Tankless Water Heater Installation Costs
Several factors contribute to the cost of installing a tankless water heater. Consider the water heater type, required capacity, and potential plumbing or electrical upgrades. Installation complexity can also affect pricing.
Potential Long-Term Savings and Benefits
Despite the higher initial cost, tankless water heaters can lead to significant long-term savings due to their energy efficiency. Tankless water heaters heat water on demand, using less energy than traditional models that constantly heat and store water. Over time, this efficiency can result in lower utility bills and a quicker return on investment. Additionally, tankless units typically last longer than traditional models, which can further enhance the overall value.
Conclusion
Tankless water heaters offer many benefits, from energy efficiency and unlimited hot water to space savings and long-term durability. They provide an ideal solution for homeowners looking to upgrade their water heating systems and reduce their environmental footprint. With proper installation and regular upkeep, a tankless water heater benefits you for many years, making it resourceful and cost-effective.
