Water shortage? Hot water circulating pump systems save a lot of water!

!±8± Water shortage? Hot water circulating pump systems save a lot of water!

If you live in an area affected by a severe water crisis, you should get a hot water circulation system for research. Recycling systems save a significant amount of water, and simultaneously give the user more quickly. Fast hot water is a commodity that once you have tried hard to do without. Not only that, but if you must do to run it down the drain for a long time to get there, it feels very guilty of this ... or at least me.

SinceA variety of circulation systems on the market, we will study different systems to get an idea of ​​what the differences are getting. There are advantages and disadvantages of each system, and they know what they are, you can make an intelligent decision if you would benefit from such a system, and to buy what type of system.

We can begin with the traditional cardiovascular system. The traditional system, the hot pipe from the outlet of the water heater is connected to the first light,and then in a loop from device to device, and ultimately connects back to the entrance of the heater. There are in circulation in the line that provides water circulates in the pipes. The pump can be set to a time so as to reduce heat loss from the system and the pumping energy during periods of little or nothing.

The traditional system is very wasteful of energy since they are all hot hot, hot weather continues to lose continuously for the environment. The heater has to work much harder thanwith a non-circulatory and could end up as necessary to replace much earlier than normal. The system is a waste of energy that are not used for residential construction in California. Grundfos and Taco are manufacturers of traditional pumps.

A better approach is to use what is called "hot water system." It is similar to a conventional system, but uses the line as cold as the return line. A small pump is placed under the sink farthest from the heater. If 'The pump is turned on, water pumps from the stove and the cold line. In fact, it is pumping water into a large loop from the heater and back into the stove. Nothing goes in or out of the water main and not run down the drain.

When the heated water reaches the pump turns off. Now you have hot water without running all down the drain. According to Grundfos, a leading international manufacturer of circulators, a typical family can save up to 16,000 gallons perYear with a circulation system. Demand systems do not use more energy than a non-circular, since it does not really circulate the water, they only have the pump on the sink, where to go anyway. The pumps run on such a short time, that energy consumption is very low ... usually less than $ 2.00 per year. With a request to save time, water, energy and money.

Another type of system is somehow halfway between a traditional and a demand system. This system usesa pump that connects between the hot and cold lines, such as application systems, but in a continuous or on a timer, as the traditional system. The switch of the pump at a temperature and a second higher temperature, the tubes stay warm temperatures. As the pump runs the cold line often ends with plenty of warm water, and if you're the hot water tap is not hot make it hot. Because the traditional system consumes much energy, because the tube keeps warmer than normalfor a long time. Laing and AutoCirc RedyTemp are two systems of this type.

The real question systems are by far the most efficient and save as much water as traditional types of systems. Traditional systems are not generally in existing buildings because of the large hydraulic rule together with the costs of operation for the loss of heat must be installed. Demand systems range in price from less than $ 200.00 to over $ 500.00. In many cases, the systems are entitled to discountslocal water utility. In some cases, the refund can cover the full cost of the system.

Saving water and energy, the greenhouse gases released into the atmosphere as a result of reduced pumping, treatment and distribution of drinking water. So, be green, and install a circulation system in your home.
