Buying Guide

Type of Indirect Water Heater

For those who already have a boiler installed, I suggest going with an indirect model that includes a tank. However, before purchasing an indirect water heater, you should verify that your boiler is compatible with such a system.

Additionally, you may see if the indirect water heater you wish to buy is suitable for use with your boiler.

Make sure the water heating systems are compatible with your home's energy setup.

Do you intend to link it to a boiler? Do you plan to use it with a cord and plug? Is it limited to gas-powered boilers only? Do tank-mounted gas-heating devices need to be installed? These are just a few examples of the kind of things you should be considering.

Having a furnace makes a tankless indirect water heater the most practical choice.

Energy Efficiency and Other Technical Specifications

Think about the product's energy efficiency rating. An improved energy efficiency is usually indicated by a higher grade.

Also, before making a purchase, it's a good idea to look into the product's other technical details. The Recovery Rate (RR), First Hour Rate (FHR), and British Thermal Unit (BTU) ratings are just a few examples.

Understanding how much hot water the system can produce in the first hour is crucial, and the FHR does just that. To make sure, multiply the system's capacity by 0.70 to get an accurate reading. The RR can be included afterward.

Ideally, you would install a high FHR indirect water heater. It should be set to provide as near to your maximum daily demand for hot water as possible.

Capacity

For a family of three or four, an indirect water heater of 40 gallons should be adequate. A smaller capacity indirect water heater may be appropriate for a home with just two occupants. Large families, however, find the opposite to be true.

Find out how much hot water you use on a daily basis on average. You want it to be lower than the tank's maximum volume.

If you need 35 gallons of hot water per day, for instance, a 40-gallon tank will be adequate. It is expected that the disparity will be sufficient to cover any unforeseen circumstances.

Customer Reviews

The opinions of consumers on a product can be quite helpful. Your understanding of the product's functionality in the actual world can benefit from these encounters.

You could also find out some of the product's pros and cons. If you know you want an IBC, for instance, you may read up on the best IBC indirect water heaters.

Size

To begin, realize that an indirect water heater will require sizing prior to or after purchase. First, you'll want to determine the square footage of the area that will house your water heater's storage tank. A similar online size calculator can help you determine your requirements.

The tank capacity is specified on the product label you'll see after purchasing. The best course of action is to take measurements and then compare them to the available options or to select a heater that fits the space, such as one that is less than 45 gallons.

Power Usage

When looking to purchase an indirect water heater, it is also important to examine the amount of energy that will be required to run the unit. Having a portable model with several outlets will negate the need for extension cables if you intend to use the heater in more than one location.

You should look for water heaters that can be positioned close to a power source if you want to use your tank in multiple rooms of your house.

First-hour Rating

Within the first hour of usage, every water heater must provide adequate hot water at the desired temperature. That's why it's important for consumers to always check the FHR, or first-hour rating, of any gadget they're considering purchasing. This is the amount of hot water that can be produced by the indirect water heater in the first hour of use.

It's possible to get indirect water heaters with an FHR of 460 gallons, despite their relatively small capacity of 70 gallons. However, the FHR for some 30-gallon units is 190 gallons. Both the boiler's BTU output and its total energy efficiency play a role in the ratings.

The total flow rate of all hot-water fixtures can be used to estimate the peak demand for hot water. The typical range for shower flow rate is between 1.5 and 3.0 gallons per minute (GPM), whereas the range for dishwashers is between 2.0 and 4.0 GPM. In order to select the most appropriate FHR, it is necessary to calculate the household's peak hot water use.

If everyone in a household takes a 10-minute shower, it uses 45 to 90 gallons of hot water each day. As a result, the 190-gallon FHR is an adequate size.

Insulation

Indirect water heaters rely on the continuous operation of a boiler or furnace to maintain the desired water temperature. Boilers and similar space-heating devices are not always operational, which is a major drawback. As a result, heat loss is a possibility.

Because of this, you should inspect the insulation surrounding the indirect water heater. Polyurethane is used for insulation in most items, while polybutene is used in a small percentage. The thickness of the foam makes a difference in its ability to insulate and retain heat.

Price

The price tag on an indirect burning water heater can range from $600 to $4,000. Although cost is often indicative of product quality, it is still wise to do some background reading on the item you plan to purchase.

Contrary to popular belief, not all high-priced indirect heaters are better than their lower-priced counterparts.

Warranty

The piece of mind afforded by the limited lifetime guarantee included with some models of indirect water heaters is substantial. It's a proxy for the product's actual performance and build quality. After example, no business would want to guarantee the quality of an indirect water heater for decades if it wasn't sure the product would last.


FAQS

What are the most trusted indirect water heater brands?

The Burnham brand of indirect water heaters is known as one of the most trustworthy options available. The company's products are well-liked by consumers because of the advanced technology they incorporate.

Triangle Tube and HTP are two further resources you could look into. These two manufacturers produce high-quality water heaters that are both effective and durable.

If taken care of, the system has a long lifespan.

The Buderus indirect water heater is a good option if you're short on installation space. This manufacturer is well-known for its compact products. Westinghouse and American Standard are two further well-known manufacturers to consider.

There are a number of other well-liked options, including Rheem, A.O. Smith, Crown, and Amtrol. Each manufacturer's lineup of products offers a wide variety of options. It is in your best interest to learn about the distinctions between them. Choose only the indirect water heater that can meet your family's needs.

How long does an indirect water heater last?

The typical lifespan of an indirect water heater is 20 years. A quarter-century of use is nothing unusual for certain brands. The structure of the goods is to blame for this.

Unlike traditional water heaters, these do not heat and chill extremely quickly.

Indirect water heaters take a while to heat the water in the storage tank. Likewise, the system is not shocked by the introduction of cold water from the tank's upper reaches. The slower rate of temperature change in water keeps the metal from rapidly expanding and shrinking.

There aren't many moving parts in a tankless indirect water heater, so it shouldn't degrade much over time. In addition to being more efficient, several of these items also have a more sturdy build quality than standard water heaters.

Indirect water heaters last a long time but need to be serviced frequently. By flushing the tank on a regular basis, you can keep your system running smoothly.

How does an indirect water heater work?

Electricity is transferred through a heating coil that is immersed in the tank of an indirect water heater. The water within is heated, and the steam escapes through the output faucet. Really, it's that easy!

What is an indirect vs. a direct water heater?

The aforementioned model is an example of an indirect water heater, while a direct tank employs direct electrical current to warm the coil. The internal liquid is heated in this way to produce steam on demand. The operation is very similar to that of a conventional electric range or oven.


Conclusion

Whether it's due to a lack of storage space or simply a need for more consistent hot water availability, every home might use an indirect water heater. This type of tank makes it possible to have unlimited access to hot water.

It's not always easy to figure out which indirect water heater is best for your household or business. You need one that won't break the bank but will still have all the bells and whistles you need, so we culled the best reviews and recommendations to present you with these six possibilities. Please use this information to guide your final purchase decision.
