Many customers have asked us about water conservation over the years. It is a natural progression to want to save energy and save water.
We offer a few products that we feel perform well, live up to their water conservation expectations, and are affordable.
1. Tankless Water Heating
Noritz has been an innovator in the water heating industry for over 60 years. Noritz introduced the first modern, electronically controlled tankless water heaters in 1981 and remains the leader in energy savings and superior hot water delivery today. Serving both homeowners & commercial users across the U.S. and Canada, Noritz America offers a broad range of tankless gas water heaters to meet the varying needs of its broad spectrum of customers.
Benefits of a Tankless Water Heater:
- A tankless water heater can save you up to 40% of your current water heating bill.
- More compact, saving space
- A tankless water heater reduces carbon emissions, equivalent to planting 33 Cypress tree.
- A Noritz tankless water heater lasts twice as long as traditional tank water heaters, dramatically reducing landfill waste. There is an average of 7.3 million traditional water heaters disposed into landfills each year in the US.
- 12-year replacement warranty on heat exchanger
2. Water Recirculation Pumps
PROBLEM: Waiting for hot water is miserable. Plus, this wastes a lot of water. Over a year, the wasted static water in the average home equals 11,461 gallons. That’s 9% of the average home’s total water use of 131,000 gal/year.
SOLUTION: A Water Recirculation pump installed by Solarponics.
How a water re-circulation pump works: By adding a water re-circulator pump, located at the water heater or at the faucet farthest from the water heater, hot water is circulated through the "cooled" hot water pipes until the water is hot at the faucet. The cool water is circulated back to the water heater via the cold-water line, and no water is wasted during the wait. The energy use of the re-circulation pump is less than operating a 25-watt light bulb.
SAVINGS: Saving 11,461 gallons of water per year adds up to 114,000 gallons over 10 years (the equivalent of 9 in-ground swimming pools) and $1,600 in water cost savings over 10-years when you factor in water rate increases.The system will pay for itself. The added value is in comfort and convenience of hot water on demand.
WHAT DOES IT COST? The average water re-circulation pump should run around $1,200 for proper installation and quality equipment. Addition costs to consider are energy use. The average pump will use about 219kWh per year, costing around $48 (based on a .20¢/kWh rate). Water recirculation pumps can be installed in one day.

HAVE A SEPTIC SYSTEM? Imagine removing 11,000 gallons of water from your septic system each year.
More Water Use Data and Facts:
Every year on World Water Day since 1993, the community of nations has focused on the importance of fresh water and advocated for the sustainable management of freshwater resources. Severe droughts experienced recently in places like the American West, the Horn of Africa, Russia, China, and Australia have highlighted the fact that humans are rapidly using up the world’s freshwater supplies—and when they’re gone, they’re gone. We are spending one of our most vital resources in greater volumes every day, according to a report by CleanTechnica in May, 2014.
Water and energy are closely interlinked and interdependent. Energy generation and transmission requires utilization of water resources, particularly for hydroelectric, nuclear, and thermal energy sources. Conversely, about 8% of the global energy generation is used for pumping, treating, and transporting water to various consumers.
If you didn’t know, we use water to pump crude oil out of the ground, remove pollutants from power plant exhaust, flush residue after fossil fuels are burned, cool power plants, and much more. Our ngenergy resources rely on water, much more than we probably realize. Exactly how much water?
Technically speaking, solar panel manufacturing does use some water. Even so, solar uses 96% LESS water than Nuclear power. This is a very relevant statistic for us here on California's Central Coast. Being that we're in a severe drought, and we get most of our energy from Diablo Canyon Nuclear Power plant, the adoption of solar energy will save us money and water. Lots of water.
We also need to consider how energy industries have water expenditures even after power is generated, all the way through to decommissioning of the power sources.
The analysis gets complicated at this point. No one has yet come up with solid numbers for the storage and post-generation stages of energy water. Here are some guesstimates from solarenergy.net:
Coal: A typical 500-MW coal-fired power plant will create close to 200,000 tons of sludge waste per year, according to the Union of Concerned Scientists, as well as 125,000 tons of coal ash. This waste leaps into the headlines when it spills into waterways, destroying rivers and polluting drinking water, as it has at large scale in Tennessee and North Carolina in recent years.
Natural Gas: The post-generation water impacts of natural gas are negligible, although the EPA notes that “pollutants and heat build up in the water used in natural gas boilers and… is often discharged into lakes or rivers.”
Nuclear: There are no hard data, but one estimate—which may be on the low end—puts nuclear waste disposal’s water use at 3 gallons per MWh of energy generated.
Rooftop Solar: Another instance where hard data don’t exist, especially not on a per-MWh basis, but several studies have shown that both solar panel manufacturing and disposal can create toxic waste that affect water supplies, such as when lead or cadmium seep into groundwater when end-of-life panels are sent to landfills. However, the Silicon Valley Toxics Coalition, which has studied these issues extensively, notes that those wastes can be reduced and avoided through responsible recycling practices, and that state and federal laws govern proper disposal of solar panels.
Wind uses a bit less water than solar, but both are exponentially more water-efficient than other energy sources.
So now you know. You need water to make power. Using solar won’t just save you lots of money. It will also help all of us conserve precious fresh water and switch over to less wasteful and less dangerous energy from renewables.
