Tankless Water Heater Saves Energy, Money, and is Green

Posted on : by : admin

The water heater is one of the neglected appliances in homes, usually hidden in some corner of the garage. We don’t pay much attention to it until it breaks. It has been around in its current form for a long time. It was invented in 1889 by Edwin Ruud and not much has changed since then. It consists of a 40-gallon or larger cylindrical container with a gas burner or sometimes an electrical element. Heat the water slowly and keep it warm all the time.

Its burner has a pilot flame that continuously burns gas, and the main burner periodically kicks in to heat the water again because the water in the container has cooled. Well this goes on day after day even if the water is never used. This is because the water gives its heat to the surrounding environment. It’s like always having a kettle full of water on the stove. Newer tank water heaters are better insulated than before to reduce standby heat loss, but nevertheless they lose heat and the water must be constantly heated. In today’s times when energy has become expensive and will become even more expensive, this is a total waste of energy and money. It also burdens the environment unnecessarily and contributes to global warming and climate change.

The tank water heater is also very inefficient, not only does it lose its heat, standby heat loss, but it also doesn’t do a good job of heating the water through its inherent design. When new they are about 55% efficient. Depending on the hardness of the water it can quickly drop to around 30 percent due to the accumulation of water sediments at the bottom of the tank, just like the kettle where water sediments accumulate when the water is heated over and over times. The WH tank also has health problems. Bacteria and germs love standing warm water and grow easily and quickly in that environment.

The water is usually not hot enough to kill them. Over time, rust can also accumulate in the water tank which reduces the heating efficiency of the WH as well as being delivered to the bathroom taps and kitchen sink. Sometimes you can see rust in the discoloration of the tile joints. Not all of this is unhealthy, but many times it is simply undesirable. The WH tank pushes some of this sediment out and some of it remains in the tank and continues to accumulate. It is not only in the bathrooms that we use hot water, although most of it is used for bathing. Sometimes we also use hot water for washing dishes and preparing food. Now, if you could see all those microscopic foreign elements, bacteria and sediments, you’d think again about using it for food or even bathing the kids in the tub with that water Waterlooexterminators.ca

We have all run out of hot water by showering or bathing. And there is no rapid heating of the water. The WH is not designed for this and it still takes a lot of energy and time to heat 40 or more liters of water. Many families have to schedule their showers because in a multi-person household, hot water runs out quickly. To make the hot water last a little longer you can run the WH at a higher temperature; say 180 degrees Fahrenheit so as to mix more cold water with hot water. Running the WH at higher temperatures wastes even more energy and with it obviously money.

People usually shower in the morning before they leave the house for work. The WH is not smart in knowing that everyone leaves the house after a shower and you won’t need hot water until late afternoon when everyone returns home. Then heat the water again and keep it warm all day by heating and reheating it again and again. And he obviously doesn’t know that you won’t need hot water after taking a shower and after falling asleep, so he reheats the water again and keeps it warm overnight.
Leaking your tank water heater can be expensive.

Well, the other problem with WH tanks is that they tend to lose water over time. Sometimes this happens for a long time without being noticed. Since most water heaters are placed in the garage, they are usually out of sight and no one is paying attention to them. So water damage due to a water leak can go unnoticed for a long time and cause significant damage to the home and the surrounding environment as well as wasting water and energy. Water damage to subfloors or other house structures is not uncommon, and repair tends to be expensive because it wasn’t detected early.
