However, before considering these factors, you must first examine your home’s needs in terms of the size of household, the availability of space and the budget. The following are some of the different types of water heating system.
Conventional Storage Water Heater
This is the most common type of water heater used by homeowners. The power used in this type of water heater can be natural gas, oil, liquid propane or electricity. You can use any of these depending upon the available fuel source in your area. When the tap is turned on, hot water is released out of the tank and cold water is drained into the bottom of the tank to replace it. Heated water is stored in the tank and reheated when needed. This type of water heater is low-priced which includes the installation. It also comes in many sizes that can accommodate the size of your household and the space available. It can last up to 10 to 15 years. Storage heater has an average energy-rating factor of 0.67. It may run out of water depending on the usage and on the tank’s storage capacity.
Tankless or Instantaneous Water Heater
Although this type of hot water system is expensive plus the installation, you will not be paying much on water bills since the water is not frequently heated. It does not store hot water. Water is heated by the time you will need it. This type also does not need much space since it requires a little and it can be placed inside or on an outside wall. The disadvantage of using this type is you will not be able to use this at the same time. For instance, you cannot do the laundry while you are taking a shower. Tankless water heater is expected to function for 20 years or more. It has an average energy-factor rating of 0.75.
Heat Pump Water Heater

It works best in regions that is warm and temperate that ranges between 40° and 90° F. Heat pump water heater operates by extracting air from the surroundings and uses it to heat the water tank. Although it has a higher initial cost including the installation compared to storage water heaters, this type has low operating cost.
Solar Water Heater
To heat water, this system uses the sun’s ray. It absorbs the energy from the sun. When the sun’s energy is not enough, backup power used are either electric, gas or wetback. This is quite expensive and time-consuming to install but has low running cost annually. The heating system’s life expectancy is 20 years or more.
