A tankless water heating system is a newer technology that’s been gaining popularity recently due to its efficiency and unlimited output for both consumer and commercial applications. Most systems of this type can provide hot water to multiple points in a building or residence, although there are point-of-use systems as well for singular fixtures.
These systems are typically powered by natural gas, propane and sometimes electricity – regardless of the power type, these units usually have 82% – 98% greater efficiency over tank-styled systems. This means less carbon emissions being produced and thus a greener choice for the environment.
This is because there is no need for a large holding tank and this new technology provides hot water on demand, thus instantly having a significant increase in efficiency over older, dated tech.
This new technology uses a heat exchanger (gas or electric powered), as it runs though the unit to warm the water often times in a negative feedback loop until it reaches the set temperature, hence providing the continuous supply. It also features a electric ignition, eliminating the need for a traditional pilot light. By addressing these key issues, the common cycle of heating and reheating with the standby loss of energy is no longer.
Tankless water systems come in a range of sizes, and are capable of a regulated flow to multiple outputs with no temperature fluctuations. Most provide a flow rate of 3 to 5 gallons per minute, while larger units can handle upwards of 8 to 10 gallons.
