Is A 75 Gallon Water Heater Big Enough For My House?
One of the worst experiences in a bustling family is that of jumping into a shower, only to find that the hot water has been depleted. The icy realization that a replacement may be in order is the beginning of an investigative process that may leave one more confused than ever. There are so many models available, and so many factors to consider, that it seems every reference has a different formula for determining the right sized water heater for a family. Additionally, water heater cost can influence one’s decision, when it comes to selecting a new system.
The factors affecting one’s selection of a replacement water heater are varied, but there are a few basic considerations to begin with. Family size is the predominant indicator of hot water usage. An individual or couple will rarely need to upgrade to a larger system. The standard for most residential water heaters is 40 to 50 gallons, and this will generally accommodate a small family’s needs. As a family grows, the use of hot water is directly influenced, based on more bathing, more laundry, and more dishwashing. A 50 gallon water heater may be perfect when the children are young, but as they get older, shower times increase. Larger families will use a greater amount of hot water, and a larger capacity water heater is a sensible solution.
The number of bathrooms in a home may also influence the need to consider a larger water heating system. More than one shower in use at the same time means that the tank will be depleted of hot water more quickly. A large capacity water heater provides a longer time during which hot water is available, making it a better solution for a household that handles much of its hot water activity in a short time frame. Evaluation of the system present may provide insight into the extent to which capacity needs to increase. If a 50 gallon water heater doesn’t quite meet the needs of the household, for example, then upgrading to a 75 gallon water heater may be the perfect solution.
The presence of appliances that use hot water plays a minimal role in determining household needs for water heating. Dishwashers and washing machines both use hot water, but these appliances aren’t often used at the same time that bathing is taking place. If appliances are competing for hot water usage in one’s particular case, a larger capacity tank should alleviate the problem. However, adjusting the household schedule may also alleviate the depletion of hot water, and avoid water heater costs associated with replacement.
There are many formulas to be found relating to each of these factors and the water heater size that suits the circumstances. These guidelines tend to vary somewhat from one manufacturer to the next. Further, the sizes indicated through research aren’t always available in a given locale. Fuel impacts household needs, as well. Gas and propane water heaters have a higher rate of recovery than electric water heaters. Smaller tank sizes will accommodate a family using non-electric water heating. Generally, a 2 person household will function well with a smaller tank size, ranging from 40 to 50 gallons. 3 to 5 person households will be better served by a 50 to 65 gallon capacity, while a 6 to 8 person household will be better served by 75 to 100 gallon water heaters. 120 gallon water heaters exist for residential use, and suit the needs of a very large household.
The space available for a water heater may determine the sizing options. If the system is contained in a small room, a larger water heater may not fit. Although a 75 gallon water heater might be the best choice for a family, the design of the tank might make it inadequate for the space available. A 120 gallon system might be enticing for the family that loves to take long, hot showers, but the door frame may make it impossible to get the device into the correct location, making it a poor choice for that particular home.
High recovery rates reduce the needed tank size for many households. However, the water heater cost for a high recovery system will be greater than for a regular recovery system. Alternative systems are becoming increasingly attractive, as tankless water heaters provide a space saving solution. These on-demand hot water systems assure that there is never a lack of hot water. In the case of gas-fueled tankless systems, this is also an energy conserving alternative.
The decision to upgrade one’s water heater is not always based on extensive research. Urgent replacement due to a failing system may dictate an immediate choice. It’s not difficult, however, to assess whether the system in place has been adequate, or whether a larger system would be appropriate. Whether replacement is a consideration or a necessity, these influences are helpful in deciding on a new water heater.
