An amazing fact to state is that heating water is the second largest single user of electricity in any home and while a hot shower is soothing the energy costs keep rising, and there are also the environmental effects of the water heater the least a person can do is select a good water heater.
There are three types of water heaters that are storage tank, solar, tankless solar heaters, solar water heaters and heat pumps. Storage tanks are the most common hot water systems that are used in homes. Such tanks use a heating mechanism where the water is constantly preheated in the storage tank by natural gas, propane or oil and then the water is drawn out from the top of the tank when a tap is turned on then cold water flows in the bottom to heat it. Such tanks are cheap and available in a variety of sizes, but one of their demerits is that they waste between 10-15% of the energy via radiation and they can run out of water during lengthy uses. These kinds of tanks have a life expectancy of one to one and half decade, and they have been increasing in size to meet the new regulations thus they may not fit some homes. Such tanks have an average EF rating of 0.67, and they can cost $200-$400 inclusive of installation costs.
Tankless water heaters, also called demand water heaters, use a mechanism where water is heated by gas or electricity as it flows throughout the system without the need for a tank. These water heaters are smaller and take up little space thus can be mounted inside the house or outside it, and they meet the new regulatory standards without the need to increase their size or installation costs. A known fact is that these tanks have little or no standby energy loss, they save close to a fifth to almost a third of the energy costs compared to standard storage tank models, and they can last for close for two decades or more. These tanks can be expensive to install with whole house installations costing between $600 to $1000 and installation.

Solar water heaters circulate the water through the tank by using a solar collector that is heated by the sun and if the water in the tank is not hot enough a standard water heater can be used to heat it up to a good temperature. These solar heaters have little to no energy costs, and they can save on energy costs for the unit for 8-12 years and have a life expectancy of two decades or more.Incredible Lessons I’ve Learned About Services
