Efficiency (Gas Only)

– Gas Tankless Water Heater Efficiency:

– Gas tankless water heaters have an energy efficiency rating called the Uniform Energy Factor (UEF). – Higher UEF ratings indicate better efficiency and lower energy consumption.

– Some high-efficiency gas tankless water heaters feature secondary heat exchangers, which further increase energy efficiency but can also increase the cost of the unit. 4.

Indoor vs. Outdoor (Gas Only)

– Indoor:

– Indoor gas tankless water heaters require venting to redirect exhaust gases outside.

– Venting involves additional materials and installation work, leading to higher costs compared to outdoor models. – Outdoor:

– Outdoor gas tankless water heaters do not require venting, reducing installation costs.

– However, they may require protection from the elements and freezing temperatures, which could add to the overall cost. 5.

Recirculating Pumps (Gas Only)

– Recirculating Pump Cost Increase:

– Some gas tankless water heaters can be equipped with recirculating pumps to provide hot water quickly. – The addition of a recirculating pump can increase the cost of the unit, as well as the installation cost.

6. Other Features

– WiFi Capability:

– Some tankless water heaters offer WiFi capability, allowing you to control and monitor the unit remotely with a smartphone.

– This advanced feature can increase the cost of the unit. – Wireless Remotes:

– Wireless remotes provide convenience by allowing you to adjust the temperature and settings from different locations within your home.

– The inclusion of wireless remotes may contribute to a higher price. – Wall Thermostats:

– Tankless water heaters equipped with wall thermostats allow for precise temperature control and customization.

– The addition of wall thermostats can increase the cost of the unit. In conclusion, when considering the cost of a tankless water heater, it’s important to take into account factors such as the GPM flow rate, quality, efficiency (for gas models), indoor vs.

outdoor installation, recirculating pumps (for gas models), and additional features. Each of these factors can impact the overall cost of the unit.

By understanding these cost factors, you can make an informed decision and choose the right tankless water heater for your needs and budget. When considering the operating costs of a tankless water heater, there are several key factors that can impact the overall expense.

In this section, we will delve into the various elements that contribute to the operating costs, including hot water demand, temperature rise, fuel type (electric vs. gas), natural gas vs.

propane, water heater capacity, recirculation, and the use of energy guides. 1.

Demand for Hot Water

– Hot Water Usage:

– The amount of hot water your household uses on a daily basis will directly impact the operating costs of your tankless water heater. – Larger households with high hot water demand, such as multiple bathrooms and frequent hot water usage, may experience higher operating costs than smaller households.

2. Temperature Rise

– Incoming Water Temperature:

– The temperature of the incoming water plays a crucial role in determining the energy required to heat it to the desired temperature.

– Regions with colder incoming water temperatures will necessitate more energy to achieve the desired hot water temperature. – Thermostat Setting:

– The temperature at which you set your tankless water heater thermostat will affect the overall energy consumption and operating costs.

– Higher thermostat settings will require more energy to heat the water to a higher temperature, resulting in increased operating costs. 3.

Electric vs. Gas

– Gas Heat:

– Gas tankless water heaters generally have lower operating costs compared to electric models.

– Gas units can provide a higher flow rate and can heat water more efficiently, resulting in energy savings over time. – Electric Heat:

– Electric tankless water heaters tend to have higher operating costs due to the higher cost of electricity compared to natural gas.

– However, advancements in electric units have improved their efficiency, narrowing the gap in operating costs compared to gas models. 4.

Natural Gas vs. Propane

– Propane Cost:

– If using a propane-powered tankless water heater, the cost of propane in your region can impact the overall operating costs.

– Propane prices are subject to regional variations and can fluctuate more than natural gas prices. – Natural Gas Cost:

– Natural gas tends to be less expensive compared to propane, resulting in potentially lower operating costs for natural gas tankless water heaters.

– However, natural gas prices can also have regional variations that affect operating costs. 5.

Water Heater Capacity

– Electric Unit kW Size:

– The size and capacity of an electric tankless water heater, measured in kilowatts (kWs), will influence the energy consumption and operating costs. – Larger electric units with higher kW sizes will require more energy to heat the water, resulting in higher operating costs.

– Gas Unit BTU Capacity:

– Gas tankless water heaters have a capacity measured in British Thermal Units (BTUs), indicating their heating power. – Units with higher BTU capacities can provide a higher flow rate and may consume more energy, potentially increasing operating costs.

6. Recirculation

– Recirculating Pump:

– The use of a recirculating pump with a tankless water heater can lead to increased operating costs.

– Recirculating pumps allow for near-instant hot water, but they require energy to continuously circulate the hot water through the pipes. – While convenient, recirculating pumps can contribute to higher energy consumption and operating costs.

7. Energy Guides

– Energy Guide:

– Energy Guides provide valuable information regarding the expected operating costs of tankless water heaters.

– The Energy Guide will indicate the estimated annual cost of operating the unit, based on the specific model and fuel type (natural gas, liquid propane). – Consulting the Energy Guide can help provide an estimate of the operating costs associated with a particular tankless water heater model.

In conclusion, several factors contribute to the operating costs of a tankless water heater, including hot water demand, temperature rise, fuel type (electric vs. gas), natural gas vs.

propane, water heater capacity, recirculation, and the use of energy guides. By considering these factors, you can make an informed decision about the operating costs associated with different tankless water heater options.

It’s essential to assess your household’s hot water needs, regional fuel prices, and the specific features of the tankless water heater to determine the most cost-effective and efficient solution for your home.
