Buying Guide – How to Choose a 40 Gallon Gas Water, Heater?

There are so many products already available in the market and choosing the best one out of them can always be a daunting task in hand. There are so many factors to consider when you are looking for the best one in the market today.

Without completing proper research, it always becomes a challenging part. You can always take the help of this buying guide if you are willing to pick the best model available.

Efficiency Ratings

One of the primary factors that you need to consider is the efficiency ratings of the product. Most of the gas water heaters are either powered by Natural Gas or the Liquid Propane gas. However, the natural gas models are better in efficiency than that of the liquid propane models.

However, before picking up the product, you can simply have a look at the energy efficiency standards that are set up by NACEA. This will help you to get the best gas water heater accordingly.

Storage Heater Tank Size

The next important thing that you need to do is to consider the capacity that you need and also the storage space. If you have a family of 4-5 people, going for a 40-gallon water heater will be a must.

However, it may be bigger than any tankless heater. So you need to make sure that the size of the tank is sufficient for your home or not. When you choose the heater, make sure that it meets your costing expectations and has all the features that you need.

Eco-friendly

When you are using a gas-based water heater, it is expected to release the expelled gas from the vents. Sometimes, they may have a higher amount of NOx or Carbon. If the quantity is more, it will start affecting the environment near you.

This is the reason why you need to be specific about choosing an indoor model or an outdoor installation model. If you are using an indoor installation gas water heater, you need to install the vents as well to make sure that the amount of NOx is reduced and is low.

Flow Rate and Recovery Rate

Another important factor that you need to consider is the flow rate of the model and the recovery rate as well. The flow rate is the amount of water flowing out of the heater in a minute. It is usually rated as gallons per minute.

Having a higher flow rate will allow you to connect multiple faucets in your home. On the other hand, the recovery rate refers to the time taken by the heater to heat the cold water and then allow it to flow. Having a higher recovery rate is thus very important when it comes to higher altitudes.

Storage Space and Installation

When you are about to install a 4-gallon water heater with a tank, it is going to take up a high space. This is mainly because it has a large tank and the size of the heater is initially big.

So before you buy the product, you need to measure up the space available on the walls of your installation area. Another factor that you need to consider is the installation options of the heater. Make sure that it is wall mountable and know about the pipes for installation as well.

First Hour Rating

The first-hour rating of the water heater is based on the time it takes to produce the hot water according to the desired temperature that you need. Having a better first-hour rating means the product is viable enough to deliver you a faster rate of hot water from the product. The rule is simple – the faster you get the hot water from the product, the better it can get for the heater. You can check more details about the FHR from the manufacturer.

Benefits of 40 Gallon Gas Water Heaters

There are a lot of advantages when it comes to choosing the 40 Gallon Gas Water Heaters. These heaters are specifically made to give you the upper hand when it comes to using the product regularly. Below, I have listed some of the benefits which you can get while using the 40 Gallon Gas Water Heaters over the electric heaters. 

1. Installation

When it comes to the benefits, there can be nothing easier than installing the gas water heaters. The electrical heaters require more configurations from the PCB board to set up the heating element. However, in the case of the 40 Gallon Gas Water Heaters, it is not the same. In fact, it may take up less time to set up.

Thus installation is much easier when it comes to gas water heaters. All that you need to do is to call a plumbing expert who will do the job of constructing the drainage pipe. Thus, the price for the installation of the gas water heater is much less than that of the electric-based heaters.

2. Running Cost

The 40 Gallon Gas Water Heaters do run with the help of either Propane or Natural Gas. Since the working mechanism of the heater is to only ignite when the water is flowing, it cuts down the costs a lot when I compare the costs with the electric heaters. When the temperature is low and you need to adjust the thermostat to increase the ignition, the electricity consumption is much higher.

Comparatively, the consumption of gas is lower which cuts down the average running costs. Moreover, gas purchases are only one time comparatively; using natural gas will save up a lot of money.

3. Efficiency

The efficiency of the electric heaters is quite decent when it comes to small requirements. This is mainly because most of the insulators are present near the outflow pipe. But, in the case of the gas water heaters, the efficiency is much higher. Thus the work progress of any gas heater is much more efficient than any electric heater.

Apart from this, the gas consumption is much lower than the electric ignition. This makes the gas-based heaters to be much more efficient than most other heaters available. If you require heavy water use, having a 40 Gallon Gas Water Heater can be highly beneficial for your needs.

4. No Heat Loss

One of the major benefits of using a 40 Gallon Gas Water Heater is that it has the least energy consumption when it comes to daily usage. To heat hot water in large quantities, the electrical water heater uses high power consumption. This will allow you to get the highest grade of the heating element when it matters the most.

However, because of the technology, the 40 Gal Water Heater allows you to get proper results at the earliest and without any delays at all.

How Did I Choose the 5 Best 40 Gallon Gas Water Heaters?

1. Tank Quality

One of the factors that came to my mind while choosing these 40 Gallon Gas Water Heaters is the tank quality and the interior tank. It is natural that if the product does not have a decent tank quality, there may be rust formation and also scaling on the interior components.

If you are staying in an area that has more contamination, you will have corrosion formation inside the tank if it is made up of low quality. This will mean that the product will slowly get damaged and will not be much durable. But with the help of a proper tank quality made up of stainless steel, things will get easier.

2. Heating Element

Not a lot of people do focus on the heating element of the product, but it certainly becomes a major factor to consider. The heating element is one of the main components in any gas heater and if it does not function properly, you may face several issues with the product. So you must choose a product that functions well.

I have listed only those products that have a decent heating component. In fact, because of this, the heating and recovery in the 40 Gallon Gas Water Heater takes place faster and much more efficiently. This also allows the heater to run for a longer period.

3. Safety Features

One of the most primary factors which I considered is the safety features of the 40 Gallon Gas Water Heaters. Safety is one thing that every consumer must consider while choosing a product. All technology-based gadgets do have the risk of failure and may cause accidents.

So to get rid of this, every gas water heater must include the basic safety features which will keep the product safe and ready to use. However, there are some features like the Temperature and pressure valve which works when the pressure gets very high.

Some of the safety features that I have considered are the automatic shut-off valve and the temperature overheat protection. Both these features are necessary to consider when the heater raises the temperature and to protect it from any severe damages.

4. Energy Consumption

Energy consumption of a gas-based heater is one of the primary factors to consider. To be honest, gas water heaters do not consume much electricity. However, there are still some factors that can affect the rate of electricity consumption at any point in time.

One of the major factors which can raise the electricity bills that I found is the volume of the heater that you are using. Now the electricity consumption of the 40 Gallon Gas Water Heaters is much lower than any instant heater. However, the efficiency factor comes into consideration. 

Apart from this, another reason why the electricity bills do get high is just because of the temperature and the climate. If you live in colder areas, the heater will have to naturally work more. This is mainly because most of the 40 Gallon Hot Water Heaters have a default thermostat setting.

So if it is not manually adjustable, the heater has to work more. In such a case, it starts consuming more ignition including both electricity and also gas. Thus, it may have a standing loss.

While picking the top 40 Gallon Water Heaters available, I had to make sure that there was an only marginal standing loss that will not raise your electricity bills easily.

5. Installation Area

One of the primary factors which people mostly do ignore is the dimensions and the size of the product. Picking any random water heater may just be bigger. In fact, because of such issues, you may not be able to install the product properly as well. While choosing any product, I always make sure that the 40 Gallon Gas Water Heaters are compact and perfect in size.

This will help every user who has smaller or compact bathrooms or even free wall area to buy the product and then use it. However, you may need to make sure that the product you choose has the proper installation connectivity area around it.

6. Pressure Bars

Another major factor that I have considered is the pressure bars of the product. This generally means that the product can perform with low and high pressure as well. There is a pressure control valve present along with the heater which allowed me to easily use the top product in a low-pressure area. I found this factor to be very helpful when it came to high rise buildings.

If you live on the top floors, it becomes difficult for you to get proper pressure on the heater. Since most of the top floor apartments have low water pressure, buying any professional heater may not do if you do not have proper pressure bars. So it is very important to choose a product that has proper water pressure.

Frequently Asked Questions [FAQs]

Q1. Is it safe to use a 40 Gallon Gas Water Heater?

A1. If you are using any gas water heater it is obvious that it will release the expelled gas. Thus, the ventilation of the heater is very important. This is mainly because the heater can emit carbon monoxide into the home. When the quantity is high, this monoxide may not be so great for your health. However, having outdoor ventilation may do the work for you well.

Q2. Can My Heater Catch Fire?

A2. If you consider the mechanism of the water heater, it tends to flow gas and then ignite it. So the gas inside the heater is flammable. However, there are many safety valves with the heater which prevents the gas from flowing outside. But this does not ensure you of a complete accidental free device. Gas leaks may happen if your product is damaged and it is best not to use any flammable object around the heater.

Q3. How Often To Flush the Heater?

A3. Oh… it depends on your locality! By this, all I mean to say is the level of contamination and sediments present all around you. If your area is affected by a higher level of contaminants, you will require frequent flushing and proper maintenance of the product. This is mainly because the sediments and the limestone will start to scale up if you do not keep flushing it. So to avoid any type of danger, you must keep flushing the heater every 6 months.

Q4. Shall I Drain My Heater in the summer?

A4. Think of it honestly… will you be able to use a product if there is complete rust formation and water is not being heated properly? Now imagine the same situation with your heater. If you keep the water stagnant for months, it will block the spigot because of the sediments. So, to get rid of this situation, just make sure that you are being able to flush it while not using it for a longer period.

Q5. How to tighten the Drain valve?

A5. You cannot do this with the help of your bare hands… You’ll need a pair of range and screwdrivers to get this. All that you need to do is to open the tank. But make sure that it is not turned on and you are not using it with your bare hands. Just find out the drain valve and turn it in the clockwise direction to tighten the valve.You can also refer to this post.
