When buying a new water heater for your home, there are many factors that you should put into consideration. The most fundamental consideration is the type/model of water heater that is most appropriate for your home. Additional considerations include the size, fuel source, availability, efficiency, and cost of the heater. Basically, the “type” factor considers the functionality and structural construction of the water heater. There are many types of water heaters, in different sizes and offered at different prices, in the market today. As such, you might need to consult a reliable plumber in your locality to advise you on a suitable model for your home. For instance, if you live in Texas, you can consult any professional plumbing company that includes Leander water heater repair services in its services page. Although there might be other creations, these are the most common types of water heaters in use today.
This is the most popular home water heater today. Conventional storage water heaters feature a storage tank or reservoir that holds heated water for home use. These water heaters use either of the following fuel sources: electricity, natural gas, propane, and fuel oil. Although some models feature heavily insulated storage tanks to reduce standby heat losses, all storage water heaters are considered inefficient because of the constant energy wastage in the stored water. As such, they are quite expensive to operate due to their energy inefficiency limitations. In addition to its size and fuel source, consider a combination of the following factors when choosing a new water heater of this type: energy efficiency and associated operational costs, first hour rating, availability, and actual price. For instance, the cheapest storage water heater may turn out to be the most costly to operate and maintain over its lifetime, while a large unit might be too expensive to buy and operate due to high energy loss costs.
Unlike the storage models, tankless water heaters do not have a reservoir/tank for storing hot water — they provide hot water on demand. Also known as demand-type or instantaneous water heaters, this type of water heater is more efficient than the storage model because it does not incur any standby energy losses; hence lowering its operating costs. Tankless water heaters use either gas burners or electric elements to heat water on demand. One functional problem with the tankless water heater is that its flow rate is limited by its output; thereby undermining its capacity to furnish all hot water needs in a typical household. Although gas-fired models produce more flow rate than electric models, you still need to install several of them to sustain your home’s hot water needs.
Notably, although they are more expensive to buy than storage water heaters, tankless models are more economical in the long run because they usually last longer and incur lower operating (energy) costs.
Instead of producing heat directly, heat pump water heaters use electricity to suck heat from the surrounding environment before dumping and using it to heat water in a storage tank — reverse-refrigeration style. Essentially, heat pump water heaters are 2-3 times more energy efficient than electric-powered conventional storage water heaters. Although heat pump water heaters have higher purchase prices and installation costs than conventional storage models, their relatively low operating costs can offset the price margin — making them more economical.
