Costs of a Tankless Water Heater

Tankless Water Heater Atlanta are designed to provide a virtually limitless flow of hot water. They also offer energy savings because they only use energy when water flows through them.

However, it’s important to note that installing a tankless heater is not a DIY project and requires professional installation. This is because the home’s gas and electricity lines must be updated.

Unlike traditional storage tank water heaters, which cost a lot of money to operate for a year, tankless units are more energy efficient and can save you money in the long run. However, a tankless water heater will cost more upfront to install. If you plan on installing a new water heater or replacing your current one, consider these costs before deciding.

The cost of a tankless water heater depends on several factors, including the size of your home, your energy usage, and your local climate. Additionally, you’ll need to factor in the cost of installation and any additional plumbing services required. It’s always best to work with a professional plumber to install your tankless water heater properly and efficiently.

Before a professional can determine which size tankless unit is right for your home, they must know how much hot water you use daily. To do this, they must take the sum of the flow rates for each hot-water-using appliance and fixture in your home. This information is usually expressed in gallons per minute (GPM). Then, they must calculate the temperature rise required to meet your desired incoming water temperature.

If you choose a gas-powered model, your plumber will also need to consider the size of your existing gas line and whether it can support the increased power needs of a tankless water heater. Lastly, your plumber must determine if you want to install a point-of-use tankless water heater or a whole-home unit. Then, depending on your preferences, they will make leak-free water, gas, and power connections in the case of a gas tankless water heater or an electric plug-in unit.

A Tankless Water Heater uses less energy than a conventional water heater because it only produces hot water on demand. As a result, it can save you money on energy costs, especially if you have a high electric bill. Depending on your location, you may also be eligible for rebates from your utility company for installing this energy-efficient unit.

However, the energy efficiency of a tankless water heater depends on several factors, including how you use it and the fuel type. For example, a gas tankless water heater requires an ignition device (IID) to turn on the flame when there’s a demand for hot water. This prevents wasting gas by turning the flame off when not using water. If you choose a gas model, ensure the unit is installed by a qualified plumbing and heating contractor who can properly install it and follow local building codes.

If replacing an existing water heater, you must retrofit the system with a new natural gas line and exhaust venting, adding to your installation cost. You may also need to upgrade your electrical service panel to accommodate the additional energy requirements of a tankless water heater.

To determine the right size tankless water heater for your home, carefully measure the space where it will be installed and consider the distance from the hot water source to each fixture. You can also reduce your energy bills by pairing your tankless water heater with a hot-water circulation system, which can speed up hot water delivery to faucets through scheduled or on-demand recirculation. Many Rinnai tankless models can be used with a WiFi module to remotely monitor power output, temperature, and energy usage. This can help detect issues before they become major problems.

One major drawback to a Tankless Water Heater is that it does not keep water hot constantly like a traditional tank system. This is because it has a small reservoir of hot water waiting to be used. When you use your shower or other appliances, the unit has to heat the water on demand as it flows through the pipes, resulting in some lag time while the system works.

This is not as much of a problem with point-of-use systems, but it can be an issue with whole-house systems, especially in larger homes. To minimize the lag time, you can install multiple units throughout your house, which allows you always to have hot water at any faucet in your home.

Another downside to a Tankless Water Heater is its energy requirements. While these systems are more energy efficient than conventional tanks, they still require electricity to run and regulate. This can be a problem in some homes prone to power outages.

It is possible to reduce the upfront cost of a Tankless Water Heater by ensuring that the system is properly sized for your household’s needs. Oversized systems waste energy, leading to higher utility bills over time. A qualified plumber can help you determine the best size system for your home and ensure it is properly sized.

A professional can also ensure that your Tankless Water Heater is installed correctly, saving you money in the long run. This includes ensuring the gas line is connected properly, and your home is wired appropriately for an electric model. If you opt for an electric model, you may need a professional to upgrade your circuit-breaker panel and wiring to accommodate the higher amperage required.

We all have to deal with power outages, but tankless water heaters are not immune. Since they rely on electricity, the circuit board that controls their on/off cycles and spark igniter will not work during a power outage. This can make your home’s plumbing less efficient because it will need to be able to run at its normal rate. Luckily, you can install a battery backup system like the HUGO for your tankless water heater to help ensure it will continue operating during a power outage.

This third-party backup battery system stays plugged in and provides an alternate electric power source for your tankless water heater. It’s compact and easy to install, and it can also keep your water heater hot for up to 14 hours during a power outage. This system works with most tankless gas water heaters, and it’s more affordable than buying a portable generator for your home.

However, if you plan to install an electrical tankless water heater in your home, it will only work during a power outage if these models require a lot of energy to heat the elements. Without the power on, your electric tankless water heater won’t be able to set temperatures, regulate water entry and exit, or light the pilot.

The BEST WAY to avoid losing access to your instantaneous water heater is by installing it in the garage. Since these units don’t have a storage tank, they’re less likely to be damaged by the cold. It’s also easier to install this type of heater since it only requires a small space footprint and can be connected to your home’s main water line.

Although tankless water heaters do not require a standing pilot light like their storage tank counterparts, they still use gas. To ensure that your new unit uses only minimal gas, you can look for a model with an IID (intermittent ignition device) that resembles the spark ignition devices used on some natural gas furnaces, kitchen ranges, and ovens.

To determine the right size tankless water heater for your home, a plumber will perform a load calculation to determine the total household’s hot-water usage in terms of gallons per minute and the temperature rise needed to bring the incoming water up to a specified point. This requires significant math to be completed correctly, and it’s best left to a professional.

Another important consideration is the ventilation needs of your new system. While traditional tank-style water heaters can be vented through a wall, most tankless models must be installed in a cabinet or on an exterior wall to prevent carbon monoxide leaks. Before recommending a location, your plumber will discuss the available venting options, including a power vent and a direct vent.

The installation usually takes about four to five hours and begins with the technician shutting off your home’s incoming water and electricity. They will then disconnect your existing system, if applicable, and remove it for disposal. They will then mount your new tankless water heater on the wall in a location they determine will be most appropriate and convenient for you.

If your tankless water heater is electric, your technician must also ensure your home’s electrical service panel can handle its energy demands. This may involve upgrading your circuit breaker to accommodate the additional demand and could incur additional costs. Unless you have extensive experience with electrical work, we recommend hiring an electrician to complete the installation for you. Doing the work yourself can void your warranty and pose safety risks.
