HTP Water Heaters: A Comprehensive Guide


Few basic amenities are as appreciated as consistent hot water. If your hot water heater is too small or broken, you understand how uncomfortable showering, washing dishes, and other tasks can be with cold water. While all water heaters may look similar, there are a surprising number of options available. Whether you need to replace a broken water heater or are looking for an upgrade, consider an HTP water heater.

This guide will give you all the information you need to make an informed decision about your next water heater. There are a large variety of water heaters available from HTP, so this guide will provide a broad range of options. We'll also look specifically at one highly rated electric water heater, the Everlast 40-gallon model. You'll see a helpful comparison with other highly-rated water heaters as well. With an HTP water heater, you'll appreciate consistent, inexpensive hot water throughout your entire home.

What Is HTP?

HTP is a highly rated company that provides water heaters and space heaters for commercial and residential use. They offer an incredibly diverse product range. You might be more familiar with their Phoenix or Everlast water heater lines, which are their most popular and provide nearly every type of gas or electric water heater you could need for your home or business. According to HTP, Everlast water heaters are particularly well-rated and popular.

Water Heater Buying Guide

There are plenty of options for water heaters. These workhorses all look deceptively similar, but you have a few major considerations to make before choosing the right water heater for your home. When you determine the design, heat source, and capacity, you'll be on your way to choosing the best brand to meet your needs.

Water Heater Design

While most homes use a storage tank water heater, there are other convenient options to explore. Storage tank heaters keep a large amount of water hot, so you can have plenty of water for showers, washing clothes, and any other household needs. They store the water in an insulated tank, which uses one or two heating elements or rods to keep the water at your desired temperature. This is the most common home unit, but you can also try a tankless water heater.

Also called on-demand water heaters, these energy-efficient units don't store any water but heat the water on demand. This allows you to save on energy since you won't be keeping water hot until you use it. However, these water heaters may not be appropriate for a large household. If you use more than one appliance at a time, a tankless water heater won't be able to meet your demand.

There are other, highly specialized models available, like solar-powered water heaters or hybrid heat pump water heaters. Hybrid models draw in hot air from the room in order to help save on electricity costs. With the right model and room temperature, you can save up to 60 percent on your overall energy cost. In general, however, most homes will use a storage tank water heater, or a tankless heater if it is a particularly small household.

Electric, Propane, or Natural Gas

There are three popular ways to heat your water: electric, propane, or natural gas. Choose based on what's available at your house. Natural gas is the most cost-effective in terms of your heating bill, but it's usually the most expensive water heater. Not all homes have natural gas available, so this may not be an option for you. If you have propane, this is another great way to heat your water while saving on your electricity bill. However, depending on your area, propane can also be quite expensive.

Electric water heaters are the least expensive to purchase and install. Consider how much you will be using your water heater and what size you've chosen, because an electric water bill can add a significant amount to your electric bill. Some homeowners use solar power or other means of generating electricity, which can save on your energy bill.

If you choose an electric water heater, you can purchase either a 4500-watt or 5500-watt model. Typical residential electric water heaters use 4500 watts. Depending on the model, you can expect roughly 18 to 25 gallons-per-minute of hot water with a 4500-watt water heater. A 5500-watt heater, on the other hand, can heat up to 23 to 35 gallons-per-minute. If you have a large family and need to take multiple showers in the morning, a 5500-watt heater can be a great way to keep up a steady amount of hot water. However, 5500-watt heaters are more expensive and have a higher electric bill.

Tank Size and Capacity

All storage tank water heaters are advertised based on the size of their tank. Most water heaters fall between 30 and 50 gallons, but you can purchase tanks as small as 5 gallons or as large as 80 gallons. While this is an important factor to consider, the most important number to use as a comparison is the first-hour rate or FHR. The FHR tells you how much hot water you'll receive in the first hour. Not only does this take the size of the tank into consideration, it also factors in how quickly your water heater can heat more water. A smaller tank that heats efficiently may give you more continuous hot water than a larger, less efficient water heater.

Additional Features

Most water heaters will advertise other convenient features. Some have a digital display, which allows you to monitor and control the temperature easily. Others have the ability to connect to your smart device and allow you to wirelessly change the temperature settings. It's great if you are away on a vacation and need to reduce the temperature while you are gone. Consider the warranty, insulation, and other features as well when determining the best water heater for your home.

Specifications of the HTP Everlast 40-Gallon Electric Water Heater

Wattage4500 watts
Tank Capacity40 gallons
First Hour Rating58 gallons
WarrantyLimited lifetime

The HTP Everlast 40-gallon, 4500-watt water heater is an excellent example of some of the great features HTP offers with all its water heaters. This sturdy water heater has plenty of foam insulation and is backed by an impressive limited lifetime warranty. This is the smallest Everlast water heater available, but still offers plenty of hot water for most households. If you need higher wattage or a larger tank, Everlast offers 52-gallon tanks and 5500-watt options for both tank sizes.

The stainless-steel elements are resistant to corrosion, and the stainless-steel holding tank offers a considerably lighter design. However, this model doesn't offer a digital thermostat or control panel, so it isn't very convenient to adjust the temperature. While it's lightweight, the tall design may not fit easily in smaller spaces. It won't fit in your crawlspace or small cabinet like a shorter model would. This Everlast water heater is an excellent option for most households and provides a very high FHR.

Price Range

There is a wide range of water heaters available, and the price can vary quite dramatically. For electric water heaters, you can pay as little as $300 or as much as $2,000. This list offers mid-range and budget-friendly models, from $348.00 to $1,299.00. The largest difference between each water heater is the warranty. Another factor to consider is the FHR. Choose the water heater that best matches your budget and hot water use. Keep in mind that more expensive water heaters may be more energy efficient, so you'll save more after years of use.

How It Compares

Ease of Use⭐⭐⭐⭐

A.O. Smith Signature Premier 50-Gallon Electric Water Heater

Ease of Use⭐⭐⭐⭐⭐
Assembly Time⭐⭐⭐
Build Quality⭐⭐⭐⭐

This premium water heater is slightly more expensive and comes with a wide range of additional features. It uses a hybrid heat pump, which allows it to use as much as 60 percent less energy. The digital controls are easy-to-use and offer several operating modes for different uses. It has a larger storage capacity and recovers 20.7 gallons in the first hour. While it costs more, you'll quickly save this amount with the impressive energy efficiency.

However, there are several downsides to this unique water heater. First, you'll need to have plenty of room to store this tank. With the hybrid features, it's 63 inches tall. That's significantly taller than most water heaters. You'll also need adequate space for the hybrid heat pump to draw warm air. This water heater only comes with a 10-year warranty, so it may not last as long as an Everlast water heater.

Rheem Performance 40 Gal. Electric Tank Water Heater

Ease of Use⭐⭐⭐⭐
Assembly Time⭐⭐⭐⭐
Build Quality⭐⭐⭐

One of the most affordable brands, this model shows the most inexpensive way to purchase a 40-gallon electric water heater. The Rheem water heater only comes with a 6-year warranty, but still offers 53 gallons in the first hour. It isn't too tall or wide, so it fits in more locations. Like the Everlast water heater, this model doesn't feature any digital controls, so you'll need to manually change the thermostat if you need to adjust the temperature. It's an excellent choice if you are on a budget but may not have the long-lasting quality of the A.O. Smith or Everlast water heaters.
