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.
In warm water circulating systems, a pump is used under bathroom sink that works in a way like temperature controlled traditional hot water circulating system operates. However, in warm water circulating systems the control temperature is set at a lower level. You can obtain instant hot water with the help of these water heaters. One drawback of using it is that many times hot water enters in cold water lines and for getting cold water you need to flush out the hot water first which leads to water wastage.
Hot water demand pumps supply instant hot water without wasting any drop of water. To initiate this system, you need to push a button and when hot water is delivered, the pump automatically shuts down.
In this system, hot water does not run into cold water lines and whenever you turn on the hot water faucets, you always get hot water supply. Things are controlled through the pump that is installed under the sink.
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.
Hot water demand systems can easily operate with tankless water heaters. If you are going to use a demand pump with a tankless water heater make sure it produces enough flow to turn on the water heater.
Therefore, with a hot water demand system, time, water and money can be saved. They also provide the convenience of instant hot water whenever the hot water faucet is turned on.
