Your Guide to Understanding Hot Water Tanks

hot water tankA hot water tank is exactly what its name suggests, it is a tank used for storing hot water. Now, the water stored in this tank can be put to two uses: domestic use and space heating. These tanks usually have a built-in oil-burner or gas system, but some models may also feature immersion heaters or an external heat exchanger. If the tank is heavily insulated then it would be capable of retaining the heat for several days. These tanks come in different sizes and they feature different delivery systems, therefore it is necessary to pick the right one that would look to your needs while being compatible with your preferences.

Tank Sizes

As far as the size of the water tank is concerned, the choice depends upon the number of occupants in the house, which is why larger houses would need larger hot water tanks. On an average, one should keep 35-45 liters per person for a day. However, it is also necessary to take into considerations the personal habits of the individuals when it comes to hot water usage. In case of presence of appliances like washing machines and dishwashers in the house, additional water should be set aside.

Delivery Systems

Just like sizes, hot water tanks feature different types of delivery systems as well like water on demand system, trunk and branch system, core system, whole-house manifold system, demand-initiated recirculation system and so on. The best hot water tank delivery system is the one that have minimum pipe run lengths with the right pipe diameters to reduce wastage of energy and hot water. If you choose an efficient delivery system for your hot water tank then you will be able to save a lot of money which would otherwise have went into installation and purchase of materials. In today’s times, people generally prefer the Water on Demand delivery system because it allows them to have instant hot water without wasting time in waiting for the water to heat up.

Ventilation and Safety Concerns

Since hot water tanks contain very hot water and they are insulated properly to reduce heat loss and energy consumption, it is utterly necessary for the tank to have a proper ventilation system. An effective exhaust vent is a must for all hot water tanks. While a standard vent works for most water tanks, it is best to have a professional determine the type of vent your hot water tank requires; after all, safety of the family members should be your primary concern!

Typical Life Spans

Last but not least, just like any other household appliances, even hot water tanks need to be replaced because they do not have an infinite life span. While these are capable of lasting for 5-10 years, they will start displaying signs when they are very close to conking off.

When to Replace

One of the sure shot signs is when the hot water tank does not supply hot water anymore or when it supplies hot water but not for a long duration. Also, hot water tanks having large or small leaks irreparable and should be replaced. In case your hot water tank make a lot of popping or clanging noises when producing hot water then you should have it checked for mechanical problems or get it replaced in case the problem is irreparable.
