What are the Benefits of Cold Water Showers?


With the harsh weather and dropping temperatures outside, using hot water can sometimes dry out our skin and hair. It may be very tempting for a person to want to submerge into a hot bath or relax in a steamy shower. Cold water is actually known to be better for you. Unlike hot water, it does not dry skin and hair, making them prone to damage. While there is no way to instantly repair years of damage done, there are some simple tips that can aid in that repair. There are some shampoos, conditioners and leave-in products that can really help reduce the damage by introducing vitamins and some oils back into our hair. There are advantages to both hot and cold water.

Residential hot water circulating systems provide the user with fast hot water providing a convenience for the user, and saving the water that would have been run down the drain.

Traditional circulating systems form a loop with the piping that connects from the heater outlet to the fixtures, and then back to the heater. A pump circulates the heated water through the loop. These systems provide nearly instant heated water at each fixture, but they are very expensive to operate. They waste huge amounts of energy keeping the pipe hot, and decrease the life of the heater. They are inappropriate for tankless heaters. Traditional circulating systems are made by Grundfos, Taco, Bell & Gusset, and others.

Laing makes a system suitable for retro-fitting to existing homes that don’t have a dedicated return line, called the Autocirc. It is a small pump that mounts under the sink, and pumps from the hot water pipe into the cold pipe, and when itreaches 95 degrees, the pump shuts off. When the temperature drops to 85 degrees the pump turns back on and the cycle repeats. The pump can handle several fixtures if the plumbing layout is correct. This system uses a lot of energy since it keeps the plumbing full of above ambient temperature water, and the cold water line ends up with tepid water not cold. The Laing autocirc is not suitable for use with a tankless water heater.

Grundfos makes a similar circulating system for retrofitting into homes that don’t have a dedicated hot return line. A pump connects to the outlet of the heater, and a thermally controlled valve is placed at each fixture in the home. The valves are connected between the hot and cold water lines. When each valve is cold water can flow from the hot line to the cold, and does so because the pump at the water heater outlet is providing pressure. When heated water reaches the valve, the valve closes. This keeps heated water near all the fixtures in the home with just one pump. However, like the Laing Autocirc, it doesn’t really deliver hot water, just luke warm, and it replaces the cold water with tepid. The system is not suitable for use with a tankless heater.
