Storage Tank Water Heater VS Tank-less Water Heater

Many a time we are faced with the dilemma of having to select between different types and brands of an individual product. The entire process can be pretty nerve-wrecking, as more often than not the wrong choice can bring with it disastrous consequences. This article aims at easing the selection process for those homeowners out there looking to invest in a quality water heating system. Before purchasing a water heater, one need not only consider the amount of water up for heating, but also the water heater’s energy saving capacity, which in return determines the sum of money you spend on fuel sources. That said, let us focus on two main kinds of water heaters available for sale.

Storage Water Heaters

The most infamous water heaters are conventional water heaters. Most homeowners prefer this heating system as it readily avails a constant supply of hot water. On average, a single-family storage tank can hold up to three hundred liters of piping hot water at any particular time. It is incredibly easy to operate, as one need only turn on the hot water tap and obtain as much of it as they wish. Cold water then runs to the bottom of the heater tank where it is heated, consequently replenishing the hot water supply. This way, one need not worry about running out of hot water, as the reservoir is ever full.

Some of the fuel sources for this water heating system include electricity, solar energy and fossil energy such as natural gas and oils. One major flaw of conventional storage water heaters is their inability to conserve energy. See, a storage tank is supposed to hold hot water at all times, regardless of whether the hot water tap is running or not. Consequently, the water is continuously being heated, and thus fuel is perpetually in use, making operating costs that much higher. To overcome this drawback, manufacturers of this water heating system have come up with heavily insulated tanks, thus reducing heat loss and eliminating the need to keep heating the water in the tank repeatedly. This, together with the use of materials with high thermal resistance in making the tanks, has significantly lowered energy consumption, thereby saving on operating costs.

The installation of a conventional water heater is dependent on various factors. Such include climatic conditions, fuel source and building safety requirements. It is, therefore, advisable to engage the services of certified plumbing contractor to ensure proper installation. If this is not an option for you, ensure you contact the manufacturer for further guidance. Frequent maintenance of your water heater, as dictated in the instructions manual, should also be conducted.

Tank-less Water Heaters

Tank-less water heaters are commonly referred to as on-demand type water heaters. Unlike conventional storage water heaters, these avail hot water only when it is required. They are therefore more energy efficient, thus saving you an estimated hundred dollars annually, with each hot water outlet. They are also relatively easy to operate. When one turns on the warm water tap, cold water moves via a pipe to the heating unit where the heating process takes place. The actual heating can either be done by an electric source or by a gas burner. Once heated, the hot water then travels through a different pipe where it’s made available to the user by turning on the hot water tap. Therefore, one does not need to for hot water to fill the tank where it is stored.

There is, nonetheless,a significant disadvantage that comes with tank-less water heaters. Unlike a conventional water heating system, an “demand-type water heater’s” yield restricts the flow rate. A standard tankless water heater outputs hot water at an average rate of fifteen liters per minute. Consequently, not enough hot water is made available for various domestic chores simultaneously. It might be impossible for one to, for instance, take a hot shower while the washing machine is running. Most people find this frustrating, and it makes them less inclined to purchasing this water heater. A simple solution to this problem is installing more tank-less water heaters to increase the output of hot water. Alternatively, one can install different water heaters for the various appliances in the house. As with the conventional storage tank water heaters, proper installation is recommended, for optimal energy efficiency to be attained.
