Did You Know?

1. The first electric water heater was invented in 1889 by Edwin Ruud, a Norwegian engineer. His invention laid the foundation for the development of heat pump water heaters as we know them today.

2. Heat pump water heaters work by extracting heat from the surrounding air and transferring it into the water. This process is so efficient that, on average, they can produce three times more energy than they consume, resulting in significant energy savings.

3. Unlike traditional water heaters, heat pump water heaters can also work as cooling units. By reversing the flow of the process explained above, they can extract heat from the water and release cool air into the surrounding space—an added benefit for hot summer days.

4. When installing a heat pump water heater, it’s important to consider its location. These units work best in warm or moderately cold climates, as extreme temperatures can affect their efficiency. Installing them in basements or utility rooms rather than outdoor spaces can help protect them from temperature fluctuations.

5. Heat pump water heaters are not only energy-efficient but also environmentally friendly. By reducing energy consumption, they help reduce greenhouse gas emissions, thus contributing to a healthier planet. Choosing this type of water heater can make a positive impact on both your wallet and the environment.

Required Tools And Equipment

To ensure a smooth and successful installation process for a heat pump water heater, it’s important to have the right tools and equipment. Here are the essential items you will need:

  • Pipe cutters: These are necessary for cutting the PVC pipes to the required lengths. Make sure to choose a cutter that is suitable for the size of the pipes you are working with.

  • Wrenches: Having a variety of wrenches in different sizes will help you tighten and loosen fittings and connections during the installation process.

  • Voltex® Hybrid Electric Heat Pump water heater: It is crucial to choose a reliable and energy-efficient heat pump water heater for your installation. The Voltex® Hybrid Electric Heat Pump water heater, manufactured by A.O. Smith, is a popular and highly recommended choice known for its exceptional performance and energy savings.

  • PVC piping: PVC pipes are commonly used for plumbing applications and are ideal for heat pump water heater installations due to their durability and resistance to corrosion.

  • PVC glue: This adhesive is used for joining PVC pipes and fittings together securely. Make sure to use a high-quality PVC glue that is suitable for your specific application.

  • Vacuum valve: A vacuum valve is an important component that is used to remove air from the system during the installation process, ensuring optimal performance and efficiency.

  • Temperature and pressure relief valve: This valve is designed to prevent excessive pressure or temperature buildup in the water heater, ensuring safety and preventing potential damage.

  • Expansion valve or expansion tank: These components are used to accommodate any expansion or contraction of the water within the system, ensuring proper functioning and longevity.

Clearance And Space Requirements

When installing a heat pump water heater, it is essential to consider the minimum clearance and space requirements. This ensures proper airflow and optimal functioning of the unit. Different brands may have specific clearance requirements, so it is important to refer to the manufacturer’s guidelines.

In some cases, an air duct or louvered doors may be necessary to facilitate proper ventilation. This allows the heat pump water heater to operate efficiently and prevents the buildup of heat in enclosed spaces.

Electrical And Plumbing Considerations

Proper electrical and plumbing considerations are vital for a successful heat pump water heater installation. Consulting a licensed electrician and plumber is important to ensure all electrical and plumbing connections are done correctly and safely.

The heat pump water heater will require a dedicated circuit breaker and specific voltage requirements. It is essential to match the circuit breaker size and voltage specifications according to the manufacturer’s guidelines.

Plumbing extensions may be required to connect the heat pump water heater to the existing plumbing system. PEX pipes or T-adapters are commonly used for these extensions. Installing shut-off valves is also necessary to isolate the water heater for maintenance or repairs.

Installation Accessories And Components

To ensure a proper and long-lasting installation, the following accessories and components are necessary:

  • Drain pan or foam pad: These are essential for protecting the flooring from potential leaks.

  • Insulated platform: This is recommended to reduce heat loss and improve energy efficiency.

  • Relief valve: It should be installed to release excess pressure from the system.

Frequently Asked Questions

What is required to install heat pump water heater?

Installing a heat pump water heater requires adequate space. These units are typically taller than conventional electric water heaters, so it is important to have enough vertical clearance. Additionally, to ensure effective operation, the heat pump water heater needs at least 750 cubic feet of surrounding air space, equivalent to approximately 8.5 feet in height, 9 feet in width, and 10 feet in depth. Creating an appropriate space with sufficient air circulation is essential for the installation of a heat pump water heater.

Where should a heat pump water heater be placed?

When determining the placement for a heat pump water heater, it is important to consider the surroundings. If feasible, it is advisable to install it in a semi-heated space like an unfinished basement or garage. This helps to ensure that it is not placed in living areas that are sensitive to colder temperatures or near a thermostat, which could affect its performance and efficiency. By situating it in an appropriate location, the heat pump water heater can function optimally without disrupting the comfort of living spaces.

Should I install a heat pump water heater?

Yes, installing a heat pump water heater is a worthwhile investment. Despite the higher initial cost compared to traditional water heaters, the long-term savings are considerable. With potential savings of around $300 per year, the upfront cost can be quickly recouped, leading to substantial savings on your monthly electric bill.

What electrical is required for heat pump?

The operation of a heat pump requires a specific level of electrical power. Typically, air source heat pumps consume electricity ranging from 545 to 7,500 watts, with the actual amount depending on factors such as the unit’s size and the season. The majority of these heat pumps draw between 4 and 20 amps and run on approximately 230 volts. This electrical supply is crucial for the heat pump to effectively transfer heat and provide heating or cooling to a space.
