How A Tankless Water Heater Works

Our Smart Water Heater

Think about the time you have stood in the shower or at the sink hot water tap waiting for it to warm up. But as hot water is required, the tankless water heater fires up to supply hot water on demand. Unlike an old tank water heater, the tankless unit has no storage tank with gallons of water and therefore, has no standby heat losses. Standby heat loss is the energy wasted by heating water only to store it in a tank.

Cold water entering the unit activates the flow sensor and the cold water is heated within the heat exchanger. The heat exchanger is a large capacity gas fired burner 5 times more powerful than the one available in a tank water heater, and unlike the tank, the burner in the tankless is modulated one BTU at a time.

Benefits of a Tankless Water Heater

Tankless water heaters are a fantastic upgrade to consider for any home. Tankless water heaters require less maintenance, have longer lifespans, are more energy efficient, have lower energy costs and have endless hot water. These lead to lower energy bills, which is important with the cost of electricity skyrocketing. Tankless water heaters work by heating the water only as needed compared to the traditional tank water heater which heats a reserve of water to temperature in a storage tank.

The lack of need for a tank also reduces the space required for a functional hot water heating system. Significant efficiency is also gained from a tankless water heater simply due to cleaner and better-controlled combustion. The upfront costs of on demand water heaters is off set when the result is endless hot water, 30%-40% higher efficiency and up to 80% lower NOx emissions.

How Does a Tankless Water Heater Work?

Tankless water heaters work on an on-demand system providing endless and consistent hot water.

Coldwater entering the unit activates the flow sensor. The flow sensor is responsible for then triggering the activation of the heat exchanger. The heat exchanger is a large capacity gas-fired burner 5 times more powerful than the one available in a tank water heater.

The cold water is then heated within the heat exchanger and exits hot and ready for everyday use. This energy efficiency results in energy savings!

The burner in the tankless is modulated one BTU at a time. The precise control of the BTU output allows complete control of the water’s temperature and cost-efficiency. Heating of the water only upon activation of the flow sensor reduces the energy required to heat your home’s water.

Maintenance of the water temperature in a storage tank or traditional boilers is more expensive and inefficient. 

An expert can assess your flow rate requirements and help make the best choice for your home’s hot water demands.
