You would not want to change water heater every now and then, right? Choosing a water heating system that will provide enough hot water and that is energy-efficient is the best. It is also imperative to consider the available types of water heaters and the identification of the right fuel source and size for your home. Here are some tips on how to select one:
Types of Water Heaters
Before purchasing a water heater for your home, it would be best to know different water heaters.
- Tankless or Demand Water Heaters – These heaters can heat water directly without using a storage tank.
- Solar Water Heaters – They use the heat of the sun to provide hot water.
- Heat Pump Water Heaters – They move the heat from one place to another location to produce heat.
- Tankless Coil and Indirect Water Heaters – They use space heating system at home to heat the water.
- Conventional Storage Water Heaters – They provide storage tank or ready reservoir of hot water.
- Availability, fuel type, and cost – The energy source or fuel type used for water heating will have impact on the size, energy efficiency and operation costs of your water heater.
- Size – Properly sized water heater is necessary to have enough hot water and maximize its efficiency.
- Energy efficiency – Know the energy efficiency of a water heater before buying it to maximize cost and energy savings.
- Costs – Make an estimation of the yearly operating costs of the water heater before purchasing it and compare them with the more or less energy-efficient models.
Water Heater Selections by Fuel Type
The type of fuel and its availability in your location may help you narrow down your water heater choices. Here are the options you may consider:
- Fuel oil – This fuel source is used in conventional storage water heaters as well as indirect combination of space and water heating systems.
- Propane – It is used in fuelling demand and conventional storage water heaters and indirect space and water heating systems.
- Electricity – Demand-type or tankless, heat pump, and conventional water heaters are fuelled by electricity. Electricity can be used with space and water heating systems including indirect water heaters and tankless coil.
- Solar energy – This energy source is readily available anywhere and fuels solar water heaters.
- Natural gas – The water heaters using this energy source are tankless or demand-type and conventional storage. It also fuels space and water heating systems with indirect water heaters.
- Geothermal energy – This energy source is available upon installation of geothermal heat pump system in homes for the cooling and heating of spaces.
Comparison Between Water Heater Types and Fuel Costs
It would be a smart idea to compare the costs of fuel, especially if you are constructing a new home. Call the utility for the existing rates or costs of fuel. Your selected water heater may also have an effect on the costs of water heating. The higher energy efficiency of electric heat pump water heater makes its energy cost lower than that of the conventional storage water heater.
To make your hot water system at home viable, be sure to install the best, right water heater.
