There is a common misconception among homeowners that, when it comes to appliances like their water heaters, bigger is always better. After all, you don’t want to be using an undersized system that is going to struggle to heat a sufficient amount of water for use throughout your home, right? That may be true, but you should also recognize the fact that an oversized water heater in Phoenix, AZ is actually no better.

There are a few issues that will affect you negatively if you choose a water heater that is simply too big for your needs. The best way in which to avoid these problems is to work with a trained professional when choosing your new water heater. That way, you will know that your system suits your needs entirely.


The first major issue with an oversized water heater is the simple fact that it is capable of heating water at a volume that you just are not going to need in your home. This is especially problematic with tank water heaters, as these models are subject to standby energy loss. This phenomena can result in serious amounts of energy waste if you choose a water heater that is too big for your needs.

Sure, you will always have a bountiful supply of hot water in your tank, waiting for use. However, because you don’t need all that hot water, it is going to just sit around in that tank, cooling off as some of its heat transfers through the tank and into the air surrounding it. Even the most efficient and well-insulated tanks are subject to some level of standby energy loss, which is why proper sizing is so important.


Not only will standby energy loss result in wasted energy, but simply paying for an oversized water heater is a waste of money right upfront. While tankless water heaters may not suffer standby energy loss, for instance, paying for one that is bigger than you actually need is still a wasted investment. Let us ensure that you not only have enough hot water for your needs, but that you are attaining that hot water in the most sensible and efficient manner possible.
