Water Heaters: Tankless or Tank
In the great debate of tankless versus tank type water heaters, we have found that not one size fits all. This is due to the fact that there are different characteristics to each that might work better in any given situation. It seems fairly obvious that not every person has the same installation requirements. In the last post, the topic of discussion was of the benefits and detriments to the point of use heater. This time out though, we will be covering the pros and cons to using a traditional tank style heater. Let us start out by touching on the positives to this method of heating water.
Tankless vs Tank Water Heaters a Price Comparison
One benefit is that the initial cost of installation is going to be less. This is especially true if one is looking to replace an existing unit of the same kind. Since the traditional sort uses a ½” gas supply and the other type needs a ¾” supply, one would not have to resize the gas line when replacing, which will cut down on cost. One more asset to keep in mind is the lower repair expense incurred with the traditional type. Parts tend to be less expensive to purchase and more readily available which is also a plus. Although it is worth noting, that if ones water heater is ten years old or older, that it may be more beneficial to replace the whole unit as opposed to repairing.
Another pro to having a tank type heater is one many people probably never think of. If there is an emergency, one would be able to use that stored water for cleaning or even drinking. This could be a valuable resource during some hardship. Despite these advantages, there are some disadvantages as well. One of them being, the 70% usable water capacity.
This means that if you have a 40 gallon unit, you will have 28 gallons of hot water able to be used and 12 gallons of cold before the tank is emptied. This same scenario can have an effect on filling large bathtubs. Depending on the size of tub, one may find themselves taking a bath with much colder water than they had hoped.
Finally, there is the fact that tank type water heaters heat water constantly, which requires constant gas usage and possibly a higher gas bill. We hope this information helps when choosing a method for heating water in a residence or commercial building.
