40 Gallon Water Heater Buying Guide

If this is your first time purchasing a water heater, there are ample chances that you’d end up with an expensive yet problematic heater. Even if you grab a good deal, the repairing and maintenance cost might leave a big hole in your pocket.

Moreover, buying a reliable heater is no easy play; you better be ready to do some brainstorming, compare products, and evaluate their features. But, fret not! I have made this water heater buying checklist after thorough research. Keep these points in mind, and you’d never face any trouble while getting a new water heater.

1. Capacity

Everything becomes useless if your water heater does not support your daily water needs. Having a family means continuous use of water in the kitchen, laundry, and showers.

If you are 2-3 people at home, a water heater with 20-30 gallon capacity would serve you needs effortlessly. Similarly, if you are a family of 3-5 people, your heater must have the least capacity of 40 gallons. Most water heaters offer above 60 gallons of water during the first hour of consumption, and this capacity reduces as the hours pass by. 40 gallon water heaters are the most practical and easy-to-use ones for residential use.

2. Warranty

Home improvement fixtures are pricy, period. Once you decide to replace something as important as a water heater, make sure it’s all worth it.

The confident manufacturers always offer a reasonable warranty with their heaters. Your new water heater should have a minimum warranty of 5 years. Rheem, Reliance, Westinghouse, Bradford, and A.O smith are some of the most trusted brands that offer a far-reaching warranty on all products.

Before spending your precious bucks on a heater, do check its warranty and repairing policy.

3. Material

There are many cheap water heaters in the market available at low costs. Although they look appealing in the beginning, they soon start showing their true colors. Plastic heaters begin to drip, and their outer core gets cracks with time.

Fortunately, most reliable heater manufacturers don’t use plastic lining in heaters. Instead, stainless steel, brass, and glass linings have now replaced plastic altogether.

Additionally, stainless steel and brass material provides better insulation and keep the heat confined inside the heater. This way, you can keep the water warm for extended periods and maintain the heater’s unharmed outer surface simultaneously.

4. Fuel type

Mainly two types of fuel are used to heat water in residential dwellings, i.e., electricity and propane/natural gas. The type of heater you get depends upon the fuel available in your home.

If the power outage is a routine in your home, forget about the electricity supported heater. Similarly, if you live in a frigid place where natural gas gets frozen inside the pipes, electricity would be your savior.

In terms of cost, electricity has the upper hand. Electricity consuming water heaters will keep your bill under control. Gas, on the other hand, is relatively expensive but lasts longer when compared to an equal amount of electricity.

5. Installation and maintenance

Unlike the tankless water heaters, the 40 gallon water heaters are pretty hard to install. You’ll have to call a plumber for installing a new heater. However, some heaters are easy-to-install, while others take more time and effort.

If you are constructing a new house, installation shouldn’t be a problem as you might incorporate two separate pipelines for warm and cold water. But, if your home doesn’t have two pipes already, go for a heater that doesn’t require extensive drilling and wading through the walls.

If you are a busy soul who is always running errands, go for a durable heater that won’t ask for regular upkeep. The stainless steel based heaters do not leak very often and are reliable.

6. Accessories

Water heaters are an essential part of every home. We all use warm water in the bathroom, wash the dishes, and do laundry. So, if warm water is such an important part of your daily routine, why don’t you buy a smart heater which saves your time and effort?
These days, heaters come with various useful accessories such as alarms, heater pans, and stands.

Although these accessories do not affect the amount of warm water a heater produces per hour, they still play a vital role to keep the heating process effortless.

The alarm installed in some heaters starts wailing when the temperature rises above a certain level or when the water starts overflowing. A heater pan is a simple yet useful accessory which collects the dripping water and keeps your house’s floor dry.
Moreover, the digital display meters which come with many heaters are helpful to keep a record of the amount of water used and its temperature. Cutting the long story short, be smart, buy smartly. The accessories will surely make this process painless and practical for you.

Conclusion

A water heater is a necessity; you cannot live without it when the water in your storage tank is icy. If you want to enjoy the winters in peace, get a reliable water heater and throw the worries of energy bills out of the window.

I hope your queries about the best 40 gallon residential water heaters would’ve been answered by now. The takeaway of this article is to invest money in useful appliances and enjoy the chilly weather without any apprehensions. Cheers!
