Tankless (On-Demand) Water Heater: Tankless water heaters, as the name suggests, do not have a storage tank. Instead, they heat water on-demand as it passes through a heating element. They are more energy-efficient than storage tank heaters since they only heat water when needed.
Storage Tank Water Heater: This is the most traditional type of water heater. It consists of a tank that stores and heats water continuously, maintaining a certain temperature. When you open a hot water tap, the preheated water is dispensed from the tank, and cold water refills the tank for heating.
Heat Pump Water Heater: This type of water heater uses a heat pump to transfer heat from the air to the water, rather than generating heat directly. Heat pump water heaters are energy-efficient and are best suited for warm climates.
Solar Water Heater: Solar water heaters use solar panels to capture energy from the sun and heat water. They can be either active systems with pumps or passive systems relying on natural circulation.
Condensing Water Heater: Condensing water heaters are a type of tankless or tank style water heater that captures the hot exhaust gases and uses them to preheat incoming cold water, increasing efficiency.
Point-of-Use Water Heater: These compact water heaters are installed near the point of use, such as under sinks or near showers. They provide hot water directly to that location, reducing the need for long hot water pipes.
Direct Vent Water Heater: Direct vent water heaters have a sealed combustion chamber, drawing air from outside and expelling combustion gases directly outside. They are suitable for tight spaces where air quality may be a concern.
