Plagued by slow hot water? - Why does it take so long to obtain hot water to the bath, shower and sink fixtures?



There are quite a few variables involved in getting the warm water from your water heater to your bathroom and kitchen fixtures. Certainly, the distance from the water heater to the components is a major consider the length of time it requires to get very hot water. Another crucial element is exactly what type of piping is utilized in your plumbing system? Is it galvanized iron pipeline, copper pipe, copper tubing, plastic pipeline or perhaps some sort of plastic tubing?

Since the material that the pipeline is constructed of can absorb heat from the water. it is an important factor to consider as well. Other elements include whether or not the pipes are insulated, the ambient temperature level around the piping, and the speed of the water through the pipe.

Tankless water heaters add to slow warm water

One last order to consider is exactly what kind of water heater you have. If you have a storage type water heater where there is a huge tank loaded with warm water simply waiting to fill the pipelines, you will get it much faster than if you have a tankless water heater. The tankless heating unit needs to first heat the water, before it can send it to you, increasing for how long it takes.

Pipe diameter makes a difference

A gallon of water will fill 63 feet of 1/2 inch galvanized iron pipe, 36 feet of 3/4 inch galvanized pipe, or 20 feet of 1 inch galvanized pipe. When it comes to type K copper pipeline, a gallon of water will fill 88 feet of 1// 2 inch pipeline, and 44 feet of 3/4 inch pipeline.

This means that if you run your faucet at 2 gallons per minute, and you have 1 inch galvanized pipe, the water will travel 41 feet per minute. Nevertheless, if you have 1/2 inch type K copper pipeline, the water will take a trip 176 feet per minute, rather a distinction. So the smaller sized the size of the pipeline, the faster the warm water will reach the fixture, given the same flow rate.

The piping product adds to slow hot water shipment

Considering that galvanized pipe has a much thicker wall than the copper pipeline and is much heavier, it will soak up more heat from the warm water as the water streams through it. So if you have galvanized pipeline it will take a lot longer for you to get hot water compared to if you have a copper pipe of the very same length.

Seasonal variations - ambient air temperature level contributes

In here the winter it will take longer than in the summertime, given that the ambient temperature level will be lower. The colder the ambient temperature level the more heat the pipeline will suck from the water therefore the longer it will take. Insulating the pipes does assist a little.

Fixture circulation rate is a huge factor in the speed of the water through the pipes

In the old days you might get shower heads that would allow flows of over 7 gallons per minute ... but nowadays whatever is low circulation. The majority of showers now are restricted to 2 gallons per minute and numerous faucets are listed below 1 gallon per minute. This includes considerably to the time it takes to get hot water.

Instant hot water systems utilize a pump to speed up the water

There are methods to speed up the delivery of hot water to your components. Use a pump. A variety of producers offer numerous kinds of hot water pumping systems created to provide rapid hot water to your components.

The oldest design system just utilizes a pump to circulate warm water in a loop, through the warm water piping and back to the water heater. With that type of system, you have nearly immediate hot water. Nevertheless, the circulating warm water loses a great deal of heat energy so it's pricey to run. Another problem is that normally running a pipe from the last fixture back to the hot water heater is very costly.

Warm water on demand system

Another choice is an on-demand type warm water system. With a demand type system, the cold water piping is used as the return line back to the hot water heater. When you desire hot water you "demand" it by pressing a button. The pump switches on and flows the water through the piping until hot water reaches the pump. When the warm water reaches the pump it shuts down to prevent filling the cold water lines with hot water.

Now you have immediate warm water when you switch on the tap or shower, and you did not wastefully run diluted the drain while you waited. With the right pump, the hot water can get to the fixture twice as fast as typical too.

If you need to await prolonged durations to obtain your hot water, then by using a hot water pumping system you will save time, water and energy. Some such systems claim water saving of as much as 10,000 gallons a year for a family of four.
