Here is a list of just some of the things a professional plumber can do for you: install or repair gas or electric water heating, install hot water circulating pumps, fix kitchen, bathroom and other faucets, install a garbage disposal or water purification system, install or replace shower heads, install a drinking water or instant hot water device, flush out valves, clean and repair or replace pipes, install or repair all kinds of toilets. The list goes on and on. If it has to do with water, your plumber can handle it.
If you think that you are spending a lot of money with your water heater, you might be better off buying a new heater that is more energy efficient. This is so you can save your money on the costs you incur with your electricity. One of the most recommended water heaters today is the Rheem hot water services.
For long pipe runs the low flow fixtures result in more barely-warm water from the hot water plumbing to be run down the drain. That means you are running heat energy down the drain too. That is wasting energy and costing you money.
Insulate the hot water pipes. Insulating the pipes keeps them from cooling off as fast, thus the new hot water doesn't have to give up so much heat to the piping material when first called for. The hot water doesn't loose as much heat from the piping when insulation is used.
Other systems use the cold water line as the return. All water heaters have a cold water inlet, and thus the cold water supply at each fixture connects back to the water heater inlet. By placing a pump at the fixture the cooled off hot water left in the piping after the last use can be pumped into the cold water line, until the hot water reaches the fixture. There are basically two types of systems that utilize the cold water line as the return. One type of system controls the pump that's located at the fixture by temperature. When the water at the pump (fixture) reaches a pre-set temperature the pump shuts off. Typically it's about 80 or 90 degrees.
Most of the fast hot water delivery systems put a pump at the fixture and just run the water in a big loop back to the heater. There are some systems that use gravity and thermal valves to move the water, with no pump involved. Although the gravity type systems can work when conditions are right, it's not practical for most homes, and you don't really get fast hot water, more like fast luke-warm water. For this article we will discuss only systems that use a pump to move the water.
If none of this works, then you must be facing a major plumbing problem, and a plumber may have to be called for to rectify your problem. Plumbers are professional who will know where exactly is the problem and how to deal with it. But when you call in a plumber, make sure he is reputed. It would be better to employ a plumber recommended by your friends or relatives and It would be better to use a licensed plumber who knows the job well.
Now when you turn on the tap you have instant hot water. Since the pipe had to get filled with hot water anyway, you don't waste any extra energy, in fact, you often get your hot water much more quickly and thus you actually save a little energy. Because the pump only runs for a few seconds and only when you demand hot water, it consumes very little electricity; typically for a family of four it would be less than .00 per year.
