It is important to note that these are just general guidelines. The best way to determine the right size water heater for your household is to consult with a qualified plumber.
3. Efficiency
When shopping for a new hot water heater, it is important to consider the efficiency of the unit. The efficiency of a water heater is measured by its Energy Factor (EF) or Uniform Energy Factor (UEF). The higher the EF or UEF, the more efficient the water heater is.
- Energy Factor (EF): The EF is a measure of the efficiency of a water heater in converting fuel into hot water. The EF is expressed as a number between 0 and 1.0. A water heater with an EF of 0.80 converts 80% of the fuel it uses into hot water.
- Uniform Energy Factor (UEF): The UEF is a measure of the efficiency of a water heater in providing hot water over a 24-hour period. The UEF is expressed as a number between 0 and 1.0. A water heater with a UEF of 0.80 provides 80% of the hot water that a household needs over a 24-hour period.
The EF and UEF are important factors to consider when purchasing a new hot water heater. A water heater with a high EF and UEF will be more efficient and will save you money on your energy bills. On average, a high-efficiency water heater can save you up to $450 in energy costs over the life of the water heater.
4. Installation costs
Installation costs are an important consideration when purchasing a new hot water heater. The cost of installation will vary depending on the type of water heater you choose, the size of the water heater, and the complexity of the installation. For example, installing a gas water heater is more complex than installing an electric water heater, and installing a water heater in a tight space will be more expensive than installing a water heater in a more accessible location.
It is important to factor in the cost of installation when budgeting for a new hot water heater. If you are not comfortable installing the water heater yourself, you will need to hire a qualified plumber to do the job. The cost of hiring a plumber will vary depending on the plumber’s rates and the complexity of the installation.
In addition to the cost of labor, you will also need to pay for the materials that are needed to install the water heater. These materials may include pipes, fittings, valves, and a drain pan. The cost of materials will vary depending on the type of water heater you choose and the complexity of the installation.
By understanding the installation costs associated with purchasing a new hot water heater, you can make an informed decision about the type of water heater that is right for you and your budget.
