As an experienced water heater specialist, I’ve seen firsthand the significant impact that upgrading to a tankless water heater can have on a home’s energy efficiency and monthly utility bills. In this comprehensive guide, I’ll explore the benefits of retrofitting your existing water heater system, provide insights on installation techniques, and share cost-saving strategies to help you make an informed decision.
Now, this might seem counterintuitive when dealing with water heaters…
Water Heater Types
Before we dive into the tankless water heater retrofit process, let’s quickly review the primary types of water heaters available:
Conventional Storage Tank Water Heaters: These are the traditional water heaters found in most homes. They store and maintain a tank of hot water, continuously working to keep the water at a set temperature. While reliable, they can be energy-intensive due to standby heat losses.
Tankless (On-Demand) Water Heaters: Also known as “instantaneous” or “demand-type” water heaters, these compact units heat water directly without the need for a storage tank. They only activate when hot water is needed, making them a more energy-efficient option.
Heat Pump Water Heaters: These advanced systems use electricity to transfer heat from the surrounding air into the water, rather than generating heat directly. They can be up to 3 times more efficient than traditional electric water heaters.
Retrofitting to a Tankless Water Heater
For homeowners looking to improve their water heater’s energy efficiency, upgrading to a tankless system is one of the most effective retrofits you can undertake. Tankless water heaters offer several key advantages:
Reduced Energy Consumption: Tankless water heaters only heat water on-demand, eliminating the standby heat losses associated with traditional tank-style heaters. The U.S. Department of Energy estimates that homes with average hot water usage can save 24-34% on their water heating costs by switching to a tankless system.
Endless Hot Water: Tankless heaters provide a continuous supply of hot water, unlike a tank that can run out during periods of high demand. This ensures your family always has access to the hot water they need.
Compact Size: Tankless models are much smaller than traditional tank heaters, freeing up valuable floor or wall space in your home. This makes them an excellent choice for space-constrained areas like closets or under-counter installations.
Longer Lifespan: Tankless water heaters typically last 20 years or more, nearly double the average lifespan of a storage tank heater. This extended service life can provide greater long-term value.
Installation Considerations
Retrofitting your home to a tankless water heater requires some careful planning and preparation. Here are a few key installation factors to consider:
Location and Accessibility: Tankless units are typically wall-mounted, so you’ll need to double-check that there’s adequate space and accessibility for the installation. Proper venting is also crucial for gas-powered models to safely expel combustion byproducts.
Electrical or Gas Connections: Tankless heaters require either a dedicated electrical circuit or a gas line, depending on the fuel source. Your existing infrastructure may need to be upgraded to accommodate the new system.
Plumbing Modifications: The pipes leading to and from the water heater will likely need to be rerouted or resized to accommodate the new, compact tankless unit. This can add to the overall installation cost.
Permits and Inspections: Be sure to check with your local building authorities regarding any permits or inspections required for a tankless water heater retrofit. Proper permitting and compliance with safety codes is essential.
To double-check that a successful and safe installation, it’s highly recommended to work with a licensed and experienced plumber or HVAC contractor. They can assess your home’s specific needs, handle the necessary permitting, and complete the retrofit to manufacturer specifications.
Cost Considerations
One of the primary concerns homeowners have when considering a tankless water heater upgrade is the upfront cost. While the units themselves may be comparable in price to a traditional tank heater, the installation can be more involved and, therefore, more expensive.
Tankless Water Heater Costs:
– Electric Tankless: Typically $200-$1,000 for the unit
– Gas Tankless: Typically $300-$1,500 for the unit
Installation Costs:
– Electric Tankless: $300-$3,000 for installation
– Gas Tankless: $500-$4,000 for installation (including venting)
The total cost can range from $500 to $5,000 or more, depending on the complexity of the retrofit, local labor rates, and any necessary infrastructure upgrades. However, the long-term energy savings can often offset the higher upfront investment.
To help offset the retrofit costs, some local or national incentive programs may offer rebates or tax credits for upgrading to an energy-efficient tankless water heater. For example, the Canada Greener Homes Grant provides up to $5,000 in grants for eligible water heater upgrades.
Maximizing Energy Efficiency
When planning your tankless water heater retrofit, it’s essential to consider other energy-efficient upgrades that can work in tandem to maximize your home’s overall efficiency. Here are a few strategies to explore:
Improving Insulation: Ensuring your home is well-insulated, particularly in the attic, walls, and any exposed pipes, can significantly reduce heat loss and improve the tankless water heater’s performance.
Adopting Renewable Energy: Pairing your tankless water heater with a solar photovoltaic (PV) system can create a highly efficient, low-carbon water heating solution. The Canada Greener Homes Grant also provides incentives for installing solar PV systems.
Integrating Smart Thermostat: A smart thermostat can optimize your tankless water heater’s performance by automatically adjusting the temperature based on your household’s hot water usage patterns, further reducing energy consumption.
By taking a holistic approach to your home’s energy efficiency, you can maximize the benefits of your tankless water heater retrofit and enjoy long-term cost savings on your utility bills.
Sustainability and Environmental Impact
Upgrading to a tankless water heater not only saves you money but also helps reduce your home’s carbon footprint. Tankless systems are generally more environmentally friendly than traditional tank-style heaters for a few key reasons:
Reduced Energy Consumption: The on-demand heating process of tankless water heaters results in significantly less energy usage compared to continuously maintaining a tank of hot water. This directly translates to lower greenhouse gas emissions.
Water Conservation: Tankless heaters can provide a more consistent flow of hot water, reducing the need to let taps run while waiting for the water to heat up. This helps conserve valuable water resources.
Longer Lifespan: The extended 20-year lifespan of tankless water heaters means fewer units end up in landfills over time, contributing to a more sustainable product lifecycle.
To further enhance the environmental impact of your tankless water heater retrofit, consider pairing it with other green home upgrades, such as solar panels or energy-efficient appliances. Many local and national programs, like the Canada Greener Homes Grant, offer incentives to support these types of sustainable home improvements.
Conclusion
Upgrading your home’s water heater to a tankless system is an excellent way to improve energy efficiency, reduce utility costs, and minimize your environmental impact. By understanding the installation process, weighing the financial considerations, and exploring complementary efficiency upgrades, you can make an informed decision that best suits your home and lifestyle.
