Applications and proper selection of water heater
1- Choosing a water heater based on needs
Choosing the right water heater depends on your specific needs and circumstances. Here are some tips to make a better choice:
- Volume of water consumption: If you have a large family or you need hot water for various purposes (such as washing, showering, etc.), you should choose a water heater with a high capacity. Tank water heaters are usually suitable for these types of needs.
- Type of fuel: Depending on the availability of different fuels (electricity, gas, or solar energy), you should choose the type of water heater. In areas where natural gas is available, gas water heaters can be a better option.
- Installation space: The space available for installing the water heater is also important. Tankless water heaters require more space, while tankless (instantaneous) water heaters usually take up less space.
- Operating costs: The running costs of water heaters (electricity or gas) must be considered. Although solar water heaters have a high initial cost, they can be more economical in terms of long-term operating costs.
2- Important points in buying a water heater
Pay attention to the following points to buy the right water heater:
- Checking the capacity: The capacity of the water heater should be suitable for the needs of your home. Conventional water heaters are usually available in capacities of 20 to 80 gallons.
