The Advantage of EC Circulating Water Pumps

EC circulating water pumps have several advantages. They use less energy and last for years. They also require minimal maintenance. However, you should be alert to leaks and other unusual sounds, and call a plumber if you hear them. The typical lifespan of an EC circulating water pump is about 10 years.

EC circulating water pumps meet the European Union's Energy Efficiency Directive (Eurodesign) Directive. The Directive requires manufacturers to make products that are more energy efficient and reduce their carbon footprint. This directive applies to pumps, motors, computers, and other products used in the industrial sector. Manufacturers must comply with the directive if they sell more than 200,000 units per year.

There are two types of EC circulating water pumps. The traditional type uses the existing cold water line as the return line. The pump sends water to the faucet through one line and returns it through the other when the faucet is turned off. The two-line system is the most common and convenient, but it does cost extra to have a return line. If you decide to purchase a thermostatically controlled pump, be sure to talk to your plumber about your options and the costs associated with each.

EC circulating water pump systems are usually small electrically powered centrifugal pumps. They typically range from a few to several horsepower. The electric motor is typically separate from the pump body. They often have a sealed design. This prevents any water from getting inside the pump body.
