Commercial Heating Supply Industry Tips For Choosing The Proper Water Heater

by | Feb 9, 2018 | Heating and Air Conditioning

When a business needs a new water heater, the correct sizing is crucial to meet the demands placed on it. If the water heater is too small, there will not be enough hot water when it is needed. This is especially important if the business is a restaurant or a hotel, where water needs are exceedingly high. On the opposite side of the coin, if the water heater is too large, there will be money wasted both in upfront costs and in long-term costs of operating the heater. Here are some things to remember when buying a new or replacement water heater from a Commercial Heating Supply store.

Factor 1

The business owner should make note of just how many fixtures in the building require hot water. Depending on the business, these could include bathroom fixtures, pools, dishwashers, and many more.

Factor 2

What are the hours of operation of the business? Obviously, a business that is only open for a small portion of the day has a lower hot water requirement than a business that is open 24 hours a day. These operating hours and the peak needs of the business should be strongly considered whenever a water heater is being purchased from a Commercial Heating Supply store.

Factor 3

What kind of physical appliance footprint limitations are in place? Consideration must be taken as to where the heater will be placed and what the venting requirements are for the area. Also, there are local building ordinances to consider, which will vary significantly by area.

Factor 4

The correct balance between gallons and BTU capability needs to be determined. Gallons are determined by gallons per hour and should be measured by how many gallons will be required at the peak time for the business. For instance, a hotel’s peak time for hot water usage is probably in the morning, when guests are showering and housekeepers are doing laundry. However, the peak time for a restaurant may be during mealtimes, when the hot water is needed for both cooking and dishwashing.

This is why it is so important to trust the expert knowledge of a reputable HVAC wholesaler such as It takes experience to know exactly what size of hot water heater will be needed for any business.
