Factors To Consider When Choosing Horizontal Water Heater

horizontal water heater

When it comes time to replace your home’s water heater, you may choose horizontal or vertical models. Horizontal water heaters have been gaining popularity in recent years because they take up less space and are easier to install. But which one is right for your home? Here are some factors to consider when choosing a horizontal water heater:

Sizes

When buying a horizontal water heater, it is important to know the different available sizes. There are mini horizontal water heaters, small horizontal water heaters, medium horizontal water heaters, and large horizontal water heaters. 

horizontal water heater

Which size horizontal water heater you need will depend on how much hot water you need at one time. The larger horizontal water heaters can hold more hot water and meet the demands of a larger household or commercial space. 

However, it is important to note that the larger horizontal water heaters may also take up more space and require a bigger installation area. It is important to carefully consider your space before purchasing a horizontal water heater. 

Installation Costs

horizontal water heater

Installing a horizontal water heater can be costly, but there are ways to reduce those costs. Here we will look at some factors that will affect the installation cost and how you can save money on your horizontal water heater purchase.

Firstly, the size and type of horizontal water heater you choose will affect the installation cost. Generally, larger horizontal water heaters require more work for installation and therefore cost more. Higher-end models may also require additional parts or specialized installation, resulting in higher costs. 

horizontal water heater

Additionally, the location of your horizontal water heater can affect installation costs. If the horizontal water heater is placed in a difficult-to-access location, such as an attic or crawl space, it may require extra installation time and labor. 

One way to save on installation costs is to purchase your horizontal water heater from a company that offers installation services, as they may have discounts or deals. 

horizontal water heater

You can also save by purchasing your horizontal water heater from a reputable retailer with competitive prices and buying any necessary installation materials rather than having the installer provide them. 

Overall, the cost of installing a horizontal water heater will vary based on factors such as size, type, location, and who you purchase it from.

Flow Rate

horizontal water heater

Flow rate is an important consideration when buying a horizontal water heater. The flow rate is the amount of water that can be heated in a minute and measured in gallons per minute (GPM). When choosing a horizontal water heater, make sure to select one with a GPM that meets your needs. 

For example, if you have low water pressure, you’ll need a horizontal water heater with a lower GPM than someone with high water pressure. It’s also important to consider the flow rate when determining the size and capacity of your horizontal water heater, as a higher GPM will require a larger tank. 

Be sure to research and select a horizontal water heater with the appropriate flow rate for your household’s needs.

Energy Efficiency

horizontal water heater

When it comes time to buy a horizontal water heater, energy efficiency is one of the most important factors you need to consider. A horizontal water heater that is not energy efficient will end up costing you more money in the long run, as you will be using more electricity to heat your water. 

Thankfully, many horizontal water heaters on the market today are highly energy efficient and will save you money in the long run. So how do you know which horizontal water heater is the most efficient? Here are some tips:

horizontal water heater

– Look for horizontal water heaters that have an energy star rating. These water heaters have been tested and certified by the government as energy efficient.

– Check the horizontal water heater’s Energy Factor (EF) rating. This measures the overall energy efficiency of the water heater, with a higher EF indicating a more efficient unit.

horizontal water heater

– Consider investing in a horizontal water heater with advanced technology, such as heat pump technology or condensing technology. These technologies can significantly increase the energy efficiency of the water heater.

Overall, taking the time to choose an energy-efficient horizontal water heater will save you money in the long run and also help to conserve energy. So do your research and choose the most efficient option for your needs.

Warranty 

horizontal water heater

When you buy a horizontal water heater, it is important to know what the warranty covers. Most horizontal water heaters come with a 1-year warranty, but some manufacturers offer longer warranties. 

Be sure to read the warranty carefully before purchasing a horizontal water heater to understand what is covered and what is not. It is also important to register your horizontal water heater with the manufacturer after purchasing it to ensure that the warranty remains valid. 

Overall, a lengthy and comprehensive warranty can give you peace of mind when investing in a horizontal water heater. It is worth taking the time to research different manufacturers and their warranties before deciding on which horizontal water heater to purchase.

Capacity     

horizontal water heater

When buying a horizontal water heater, it is important to consider its capacity. Horizontal water heaters range in size from 10 to 80 gallons. It is important to buy a horizontal water heater that is large enough to meet your needs. 

If the horizontal water heater is too small, it may be unable to keep up with hot water demands. On the other hand, buying a horizontal water heater that is too large can lead to wasted energy and higher utility bills. 

Consult with a professional to determine the proper size horizontal water heater for your household or business.

Housing’s Material Types

horizontal water heater

When it comes time to buy a horizontal water heater, there are many factors you will need to consider. One of the most important decisions you’ll have to make is what material the horizontal water heater will be made of. 

There are 3 main types of materials used in horizontal water heaters: copper, steel, and plastic. Each has its own set of pros and cons, which you will need to weigh before making your decision.

Copper horizontal water heaters are known for their durability and lifespan but may also come with a higher price tag. Steel horizontal water heaters have a lower initial cost, but they may not be as long-lasting as copper models. 

horizontal water heater

Plastic horizontal water heaters are often the least expensive option, but they may not be able to handle high water pressures as well as the other materials.

Safety Features 

If you are in the market for a horizontal water heater, it is important to know the safety features included. Some horizontal water heaters have a built-in thermostat that automatically shuts off the heater if it becomes too hot. This prevents overheating and potential fires. 

Other horizontal water heaters include a thermal cutoff switch, which will automatically shut off the heater if it runs out of water. This prevents the heater from being damaged by dry-firing. 

horizontal water heater

Be sure to ask your dealer about the safety features of each horizontal water heater you are considering.

Temperature Ranges

When buying a horizontal water heater, it is important to know the temperature ranges different models offer. Some horizontal water heaters are designed for colder climates, while others are better suited for warmer ones. 

By knowing what to look for, you can ensure that you find the perfect horizontal water heater for your needs. Regarding temperature ranges, there are 2 main factors to consider. 

horizontal water heater

The first is the minimum output temperature, which refers to how low the horizontal water heater can go before stopping heating the water. The second factor is the maximum output temperature, which refers to how high the horizontal water heater can heat the water before shutting off. 

Some horizontal water heaters offer a minimum output temperature of as low as 90 degrees Fahrenheit, while others can reach as low as 75 degrees. Similarly, some horizontal water heaters have a maximum output temperature of 140 degrees Fahrenheit, while others can reach 180 degrees. 

It is important to consider the temperature ranges offered by horizontal water heaters, as they can greatly impact the efficiency and effectiveness of the unit. 

horizontal water heater

Make sure to research and choose a horizontal water heater with temperature ranges that meet your needs.

Ultimately, the best water heater for your home will depend on various factors related to space and budget constraints. Consider all of these factors before deciding to ensure you choose the horizontal water heater that’s right for you.
