Instant Hot Water Will Save You Water and Money!

Now that you’ve heated your water for free from the sun, it’s time to address the hot water delivery system. Stop standing there with your hand in the shower stream waiting for the water to get hot! Sending water down the drain while you wait just makes it that much worse. But there is a solution!

Demand Hot Water Pumps Save Water

A demand system pumps the hot water from your water heater to your fixture at fast without running any water down the drain. When hot water reaches the pump, it shuts off.

Turn On the Tap and Get Instant Hot Water

Now when you turn on the tap you have nearly instant hot water. When you desire hot water you just push the start button and the pump starts up, pumping the water from the water heater to the sink. At the same time it sends the cooled-off hot water in the back to the heater through the cold water lines.

Solar Powered Water Heater – Any Kind

Demand systems will work with any type of water heater including any kind of solar water heater. Direct, indirect, batch, or any other kind of solar installation will work with a demand system.

The longer the pipes the more wait time you have for hot water and the more water gets run down the drain. Often solar water heaters have more piping than standard water heater installations. This is especially true for batch type systems that have a storage tank of hot water up on the roof.

Hot water demand system pumps use very little electricity for their operation, normally less than $2.00 per year in electricity costs. Demand pumps use no more energy than if you did not have one, other than that $2.00 in electricity.

A hot water demand pump does nearly the same thing you do… turn on the hot water until it reaches the sink. The demand pump usually pumps the water to the fixture much more quickly than just running the water down the drain.

Low flow fixtures cause slow hot water.

The time it takes for water to reach the fixture is determined by the diameter of the pipe and the gallons per minute of flow. Larger pipe takes longer to fill and cause longer waits.

Higher flow rates result in higher water speeds and shorter wait times. It’s impractical to change your pipe diameter; however you can raise the flow rate by not having to run water through a low flow fixture.

Bathroom sink fixtures are often one gallon per minute or less. This means a long waiting period for you to get your hot water.

The solar powered water heater efficiently heats your water; now turn your hot water plumbing layout green and make it efficient by adding a demand pump for fast hot water and water savings.

Solar water heating and hot water demand pumps are a perfect combination for ecology and environmentally conscious home owners.

You can even use tankless water heaters with your solar water heater and a demand pump for an energy efficient, water saving, hot water plumbing system that can also provide you with unlimited hot water.

Usually conserving water is a painful process. Low flow toilets conserve water, but most people who have used them complain about their operation…needing to flush multiple times etc. How about low flow shower heads and faucets? Again, for most of us it’s not a painless way to conserve water. It’s emotionally painful, at least for me. How about all those brown yards with dead lawns? And not being able to wash your car…that’s painful isn’t it?

Well the good news is there is a way to save a lot of water without the pain and it’s called a hot water demand system! In fact, this way of saving water is actually a convenience for the user. It’s called a hot water demand system (or demand hot water system), and it can save a typical family of 4 up to 16,000 gallons of water per year according to one manufacturer, and 10,000 gallons per year according to another.

A hot water demand system consists of a small pump that mounts under the sink in a bathroom or kitchen. When the user “demands” hot water, by pressing a button, the pump begins pumping water out of the water heater, and when the hot water reaches the pump, the pump shuts off. The cooled-off hot water in the hot water pipes is pumped into the cold water line, and back into the water heater inlet. It just pumps the water in a big loop out of the heater and back in. Since the pump shuts off when hot water reaches the pump, little if any hot water makes it into the cold water line.

Since the pump only runs for a very short time, typically less than a minute, it uses very little electricity. Usually these pumps use less than a dollar or two per year of electricity. With some of the systems the pumps are powerful enough that you get your hot water in half the normal time.

If you have a tankless water heater then you are probably wasting even more water waiting for the hot to arrive, since a tankless water heater takes time to heat the water and a storage tank type heater does not. However, it takes a certain amount of flow to turn on a tankless water heater so you must be sure the pump you purchase has enough power.

There are a number of hot water circulating systems on the market, and not all of them are “demand” systems. Traditional circulating systems require a separate return line for the hot water, and the pumps run continuously. These traditional systems use a tremendous amount of energy keeping the hot water pipes full of hot water. The water heater has to work a lot harder and can wear out much more quickly. Tankless systems won’t work with traditional hot water circulating systems.

There are also a class of circulating systems that are kind of half way between the traditional system and the demand system. They use the cold water line as the return line like real demand systems, but they operate on a temperature cycle like some traditional systems. That is, when the water cools down to a pre-determined temperature the pump turns on, and when the water reaches a pre-determined high temperature the pump shuts off. The pump cycles on and off continuously keeping the water in the pipes kind of luke warm. These systems will not work with tankless water heaters either. The pumps are too small to pump enough water to turn them on.

These temperature controlled cold water return line systems also use a lot of energy since they keep the hot water (and cold water) pipes full of warm water. They aren’t as bad as the full time traditional systems, but they consume one heck of a lot more energy than a true demand system.

When considering purchasing such a system be sure to check with your local water company and or city government to see if any rebates are being offered. There are water companies that offer rebates, and some rebate as much as $200.00 per home. That’s actually more than the retail price for at least one brand of demand system.

There are a number of simple yet highly effective ways to save water now that it is becoming more and more of a precious resource. As more States have to impose water restrictions, you will find that saving water is good for the planet and it is also good for saving you money.

When you think ’save water’, I bet you think of mostly indoor things. There’s the dripping taps, the toilet that doesn’t stop flushing and uses too much water per flush, the shower head that doesn’t have a flow restrictor, the people who run the water while they are brushing their teeth or shaving. All these sorts of things need to be the forefront of your mind if you are wanting to save ater.

However, there’s also the chance of saving water outside. Using water outside more efficiently is the best way to ’save’ it. Tons of water pours from the roof and into the storm water system. This is water that you could be using every day. All you need is a tank that is filled by the water off the gutter downpipes. And if you don’t like the thought of a great big ugly tank siting in the middle of your property, there’s now no need to worry as there are a number of tank manufacturers who provide tanks that can be shaped so that they closely fit to the exterior walls of your house. These tanks also now have excellent health technology so that the water doesn’t sit around at the base of the tank, but is emptied from the bottom rather than the top. There are also excellent systems you can use, mainly using some form of meshing, which can cover over the top of your meshing to prevent all sorts of muck getting into the water. You can also use water purifying systems that mean you can even use this water inside of your house for drinking and cleaning. In fact, the water that comes from the sky, as long as your guttering and tank are regularly cleaned, may well be of a better quality than the water from your local authority.

Having this supply means that you can continue to use water outside without feeling guilty about wasting town water supplies. There are a few things that are beneficial to remember, though. If you have a sprinkler system, buy a system that will water the roots of the plants rather than just have a general spray. This will aid the vegetation in growth and also use less water. Also, arrange your garden so that the plants that need more water are grouped together so that they get the full benefits of the irrigation system and the others that don’t need much water aren’t flooded and die.

If possible, clean your car or boat on your lawn, then you can use the water to complete both tasks. Ensure you utilize organic cleaners, else you poison rather than water your lawn.

Make sure that your outside fixtures are also not leaking. Recall that through the simple drips of leaking faucets, you can lose tons of water and thus, money. So, check often to make sure your faucets are not leaking.

NASA’s International Space Station has very limited resources. This includes water. For astronauts there, water recycling is the only feasible option. Many people don’t realize it, but water is in limited supply on earth also. Only about three percent of the world is fresh water, and of that two percent is unavailable in polar ice caps, so only one percent of the world’s water is fit for human consumption.

In the United States, the average household uses three hundred and fifty gallons of water a day. That may not seem like much, but when you multiply it out over a year that amounts to 127,400 gallons. That’s a lot of water. Of that, in some homes almost seventy percent is used for watering lawns and gardens. Because of the finite nature of our usable water and the current rate with which we use it, it makes sense that so many government and environmental groups are calling for more water conservation. Water is precious stuff. While it is technically possible to make water chemically, the amount of energy needed makes it an impractical solution

“Utilities enforce and promote water restrictions through rates, municipal ordinances, federal laws and regulations, and financial incentives.” One example of this is only allowing the public to water their lawns on certain days. Or by not allowing home car washing with a hose. Some counties only permit water fountains that use recirculated water. As far as financial incentives, some counties offer them to consumers that install more efficient or low-flow plumbing or change out their lawn for resilient plants that require less watering. The country’s average for recycling wastewater is only 2.3%. However, in areas that are plagued more frequently by drought, that percentage may be as high as twenty-five percent.

Since scientists are unable to predict droughts or the length and severity of droughts, beginning and maintaining water conservation measures and programs is the only way to ensure that our area is prepared if a drought does occur. Using wastewater for irrigation or similar work, shortening showers, conservation efforts at businesses, Aquifer Storage and Recover (ASR) programs, and other responsible consumer actions can all help. Water conservation isn’t just another environmentally friendly thing we “ought to do”. It is vital to ensure there is enough water for our children and grandchildren.

Households are actually one of the biggest consumers of energy and water in the world, more than agriculture or manufacturing. This is simply due to the immense number of households in the world. However, there are plenty of strategies that we can use, right now, to cut down on electricity and water usage – and therefore, bills!

There are lifestyle guidelines, as well as choices that you can make once, and then never have impact on your life again, apart from delighting in the lower bills. Condensing water heaters and tankless water heaters, innovative home heating products, better appliance choices, as well as new inventions and systems are all explored here.

One of the biggest consumers of energy in a household is water heating, second only to space heating. This represents an average of 25% of your annual electricity bills, and can be cut down by up to 50% by installing a condensing water heater or tankless water heater. You heat only the water that you use, creating enormous savings on your energy bill.

Normal water heating products have a fixed minimum cost – even if you went on a three month overseas holiday, you would still come back to an energy bill because of your water heater. Tankless water heaters eliminate that waste, and minimize your environmental footprint.

Condensing water heaters and tankless water heaters also help save water. These units are usually very small, and several small ones can be installed over the house for the same price as one large, central one. If you use hot water from the tap several times a day, you could be wasting around 10L a day waiting for the hot water to reach the outlet.

A small energy efficient water heating product like a tankless water heater installed under the sink, or in the roof or wall near the shower, could save over 700L of water off every bill. Not to mention 700L that is better off in our river systems and dams!

Saving water is often a lower priority on household lists, as it costs less in utility bills, However, water use can still have a major environmental impact. Rainwater tanks do represent a capital investment, but can often be added to your mortgage (and then add capital value to your home).

Aside from using tankless water heaters, you can save water in the shower by fitting a low-flow AAA rated shower head. In many areas these arecompulsory for all new homes built. Grey water systems can then re-capture the water that does run through your water heating system for showers, for re-use on decorative areas of the garden – however not on any plants that are for human or animal consumption.

Insulation is important for home heating, but it is equally important for your water heating. Ensure your water heater’s pipes are wrapped in insulation – copper conducts heat very efficiently away from the water! Of course, this can be minimized by choosing condensing water heaters that are located under sinks and next to showers, anyway. Insulation in your walls can save up to a fifth of your total home energy bills.

Around 40% of the average bill is taken up with home heating and cooling, and half of this can be cut off with insulated walls, as well as curtain pelmets and double-glazed glass.
