For year after year, we turn the knob for hot water and it always comes out. Our hot water heater is one of those things we never think we have to be worried about. However, when the day comes where you turn the knob and all you get is cold or tepid water. As confusion sets in the thought finally washes over you – what type of water heater should I replace my broken unit with?

Or, the hot water heater works as advertised, but you just need more hot water. Your business has grown and you realize what worked a few years ago is not keeping up with demand.

Alternatively, you want to be more eco-friendly and get your utility costs under control. Which water heater is going to work toward those goals?

What’s your capacity?

A family of four can put some pretty good use to a water heater, pulling around 100 gallons a day, in some cases. By no means does this require you to buy the biggest hot water heater you can find; because, you’re not using that water all at once. However, there are a couple of important numbers you need to consider. Look at the heater’s first-hour rating, or FHR. This is, to a large degree, more important than how big the tank is. A tank with a high FHR will recover fast, meaning the water that is used is quickly replaced.

If you’re looking at a tank-less system, the equivalent is gallons-per-minute, or GPM. This will tell you how much hot water can be delivered over a period of time, which is often rated by the hour. A large business with multiple plumbing fixtures will require a larger tank and a more efficient FHR or GPM. Keep in mind that a standard shower uses between 2 and 2.5 gallons of water per minute. So if you have two people who each take a 10 minute shower; separately, your 30 gallon water heater is working hard to keep up. At some point, the second person is taking a tepid shower, which means you need to consider a system with a larger tank and a better FHR.

Answer these questions for better results

To get to the bottom of what will work for you, start by answering these questions:

• How many people work in the property?
• Is the water heater in a drafty area of the building?
• How is your existing system powered – electricity, gas, renewable energy or other fuel source?
• Is you water hard or soft?
• Are you looking to improve your bottom line by cutting back on utility bills?
• How long will you operate your business out of this specific property?

The number of people in the business, and the amount of processes you undertake that involve using hot water, make the size of your tank, FHR and GPM vital. A drafty property, or a water heater in a cold part of the business, drastically reduce its efficiency. If you want to stay consistent with your fuel choice, this also dictates which water heater is a good fit for your commercial property.

Your plumber has options available regarding water that’s hard or soft. They look at every question posed above to make their determination on what you should install.

Storage tank water heater systems:

In general, smaller properties with fewer people living in them find that a water heater with a storage tank and are powered by gas, to be the best option. Typically these units last around 12 years. This is the most commonly installed unit. Most tanks hold between 30 to 80 gallons of heated water. They can be fueled by propane, fuel oil, natural gas (most common) or electricity. They are economical to buy and install, but they use more energy than other types of systems.

Tank-less:

A tank-less water heater is a good choice for businesses that plan on operating out of the property for a long period of time - up to 20 years. That’s the approximately shelf life of most of these units. However, they’re usually only able to provide hot water at a rate of three gallons per minute. The perk is that they don’t suffer from standby heat loss. That is an issue with tank systems that have to continuously add fuel to the fire to keep the water hot. By installing multiple heaters, which is what larger commercial properties do, you can get more than three gallons of hot water per minute. Finally, these tank-less systems are perfect for tight spaces, because they take up much less room than a tank system.

Hybrid/heat pump water heater:

Instead of generating heat directly, a heat pump water heater uses electricity to move heat around, which makes it an extremely energy efficient machine. Most heat pumps are associated with heating and cooling commercial properties, but they are used for heating water as well. The limitation on these is to install it in a room that doesn’t dip below 40 degrees or get above 90. Outside that range the are not efficient. They also have a tendency to cool the rooms they’re in, so that has to be considered as well.

Every hot water heater has a shelf life

It’s not uncommon for a water heater to come with a 12-year warranty. If you’re coming up on that 12-year mark, or have surpassed it, you’ve got some decisions to make in the near future. While hard water can be tough on your water lines and fixtures, soft water has been found to be corrosive to various parts of the water heater, including the anode. This means the estimated shelf life of your water heater may be much shorter.
