There are three basic types of systems to solve slow hot water problems. That includes the traditional hot water circulating system, the warm water circulating system and the demand hot water system. Not all of them are green although they all save water. Here we will talk about all these systems.

In traditional hot water circulating pumps, looped plumbing is used from one fixture to another and then a dedicated line up to the last fixture. Energy consumption of these water heaters is very high as they need to maintain hot water in lines every time. They are not suitable to be used with all the tankless water heaters.

Warm water circulating systems have a pump installed somewhere under the sink and operates like a temperature controlled traditional hot water circulating system. The hot water is provided instantly in these heaters. But in this system, hot water could also get inside cold water line which causes wastage of water. As the hot water that comes out through cold water faucets has to be drained out.

Hot water demand pumps speed hot water from your water heater to your fixture without running any water down the drain. In a demand system, you can push a button to start the system when you want hot water and when hot water arrives at the pump, it shuts off.

No hot water gets into the cold water line and when you turn on the tap you nearly get instant hot water. With the help of the pump that is located under the sink, all the fixtures in the bathroom get hot water fast.

Using demand pumps, a lot of water (saves thousands of gallons) and energy can be conserved and due to this reason they makes a bathroom green where they are installed. The total energy consumed by this system cost you $2 for a year. You can get this system in around $200, so it is not very costly also.

You can use hot water demand system with any of the tankless water heater. But keep one thing in mind that when you use demand pump with tankless water heater the flow should be able to power on the water heater.

If you are plumbing a bathroom, you can go green and install a hot water demand system. With this system, you can save time, water, money and experience the convenience of instant hot water when you turn on the tap.
