Tankless hot water heaters are being used in new construction and retrofitted for older homes to replace the original tank- style water heaters. This switch to tankless hot water solutions has saved much wasted water and energy, because it heats water as needed instead of continually working to keep a tank full of water at a constant temperature.One of the downfalls of switching to a tankless hot water heater is the fact that the hot water is not truly “on demand”. It seems that it takes a few minutes of running your hot water before it actually gets hot. Even with low flow fixtures, this can dump between 3-5 gallons of clean, usable water down the drain. If this happens every time the hot water is turned on, the wasted water can add up quickly.A sustainable solution for this particular issue has been developed. If you have an electric tankless water heater, you might want to consider the minor investment (around $180) for the Chilipepper “on demand” hot water pump. This small device is installed into a system that takes the initial cold water, which would be wasted, and re-circulates it to the inlet of the hot water heater. No water is wasted while waiting for a hot shower.The Chilipepper hot water pump costs less than $2.00 per year to operate, and can save the average family of four up to 15,000 gallons of waste water a year. Independently reviewed for its “green status”, the materials, manufacturing, usage and recycle ability were examined and found to be sustainable and up to standard.So if you’re tired of watching water dribble down the drain while you wait to wash dishes or take a shower, the Chilipepper hot water pump could be your next step in water conservation.
