Many people wait for hot water in their shower each morning. A similar thing happens when people operate sinks, dishwashers and washing machines. Fortunately, this problem can be solved one of two ways depending upon how your plumbing system is designed. Clean water is a valuable natural resource and it should not be wasted. The trouble is, in many localities, water is a very cheap commodity. When prices are low, people tend to waste.
To get instant hot water as you often find at hotels and other institutions, you need to have a loop in the piping system that circulates hot water back to the water heater. Most houses do not have a loop as the hot water pipe typically dead ends at the plumbing fixture that is farthest away from the heater. It is possible but usually very difficult to install a dedicated return loop in houses because the piping required would typically be hidden in the walls, ceilings and floors of the home.
But, you don’t have to install a dedicated return loop if you choose an innovative and patented technology known as a “temperature controlled hot water recirculating valve”. It uses your existing water pipes and the thermal convection generated by your water heater to circulate the water back to your water heater for reheating (not requiring a pump or any electricity). To save water and save energy, these hot water recirculation systems have a temperature-controlled valve that allows the consumer to easily adjust the temperature to meet their particular needs. There is no water waste as it reduces the energy required to heat your water while it provides faster hot water to your faucets and showers for better water conservation. Installation is a simple DIY project (no pipe cutting, soldering or electrical connections).
Not all recirculating systems are the same. Some systems have pump under the sink requiring you to push a button to start the pump. The trouble with this type system is that you still have to wait for hot water. What’s more, this pump needs high voltage electric to operate. It can be a huge challenge to install an outlet under a sink.
Another system uses a timer to activate a pump. The trouble with these systems is that they only provide instant hot water at specific times of the day.
