Types of gas water heaters

One of the key equipment in any home or residential building, a water heater continuously supplies warm water to the different water faucets spread out throughout the structure. There are many different types of water heaters available despite the fundamental design’s relative simplicity.

Despite serving the same purpose, every type of water heater operates in a unique way. This gives each type of water heater a unique set of benefits over the competition. You may choose the water heater that is suitable for your home or project by being aware of the variations among the five primary varieties.

Storage Water Heaters

Storage water heaters, the most popular kind of water heater, heat and store water in a sizable tank. They can be powered by electricity or gas, with gas water heaters offering faster heating and electric variants typically costing less. Storage water heaters come with the caveat that they have a rather long refill time and a limited supply of hot water, and they do need frequent cleaning and flushing to keep in excellent operating order.

 Tankless Water Heaters

With tankless water heaters, you may use as much hot water as you need immediately after it has been heated. Furthermore, they tend to be more energy-efficient and less expensive to run because they only heat water when you actually need it, as opposed to continuously heating it in a big tank. Tankless water heaters are generally more expensive than their storage-based equivalents, though. Tankless water heaters can also struggle to supply hot water to several water faucets at once because they can only heat water at a specific defined flow rate, which is a significant issue for larger buildings.

Heat Pump Water Heaters

Instead of using a conventional heating element, heat pump water heaters function by transferring heat from the air outside your home to the water inside the storage tank. This translates to very low energy costs because a system like this requires very little electricity to run, which will end up saving you a lot of money over time. However, because heat pump water heaters need a specific outside temperature to function, they are only really suitable for hot climates rather than more temperate or chilly regions.

Solar Water Heaters

Solar water heaters use the solar panels on your land to heat the water, as its name would imply. The benefit of solar water heaters is that they are inexpensive to run and give you access to hot water all year round. Even systems created for usage in colder climates exist. The natural disadvantage of solar water heaters is that they need the sun to be out in order to heat the water in the tank, so if there is a lot of cloud cover, you might have to take a few showers in the cold.

 Condensing Water Heaters

Only residences with a natural gas heating system can have condensing water heaters installed. They have a hot water storage tank, but instead of using a direct gas line like conventional water heaters, they utilize the exhaust gas from your central heating unit to fuel their heating elements. This can help you save a lot of money over time while still enabling you to benefit from the effectiveness of gas water heating.

 Pros and Cons of a gas water heater

Benefits of a gas water heater:

Faster Than Electric

When compared to electric models, gas water heaters heat water about twice as quickly. A gas heater can heat a 200-litre tank of water in one hour, whereas an electric heater might take an hour to do the same. You won’t likely run out of hot water because of this. Electric water heaters may struggle to keep up with huge demands for hot water, so a gas heater is typically a better choice for bigger families.

Generally Lower Energy Costs

Despite the fact that gas storage units lose heat through the tank walls and exhaust gases, electric heaters are more expensive than natural gas even though they are more energy efficient. In terms of energy costs, this more than balances out the heat loss and makes gas heaters more cost-effective to operate.

Don’t Lose Hot Water during Blackouts

When a power outage occurs, gas water heaters that use a pilot light rather than an electronic ignition will continue to operate. Australian homes are accustomed to experiencing power outages, so having hot water even then can be very helpful.

Drawbacks of gas water heaters:

Higher Upfront Cost

A gas water heater would certainly reduce your energy costs, but gas versions are more expensive up front and require more maintenance and installation. Even though they cost more up front, most gas water heaters, when properly maintained, make up the difference in cost within a year.

Slightly Shorter Lifespan

Compared to electric water heaters, gas water heaters have a marginally lower lifespan. The electric model should last roughly a year longer than the gas model if you install a gas and electric unit at the same time.

More Difficult Installation

Installation for gas water heaters must be more intricate and incorporate a ventilation system. In order to vent through the roof, PVC pipes must be constructed if the house has never had a gas water heater. Additionally, this ventilation system will occasionally need maintenance or repairs, which might be completed when the water heater is changed.

What to consider when choosing the best gas water heater?

Gas tankless water heaters are more popular than electric ones since they are more affordable in every manner and cost less altogether. Additionally, compared to other types of heaters, the installation process for gas tankless water heaters is much simpler.

Having said that, the list above includes some of the top gas tankless water heaters. You can thus examine their features and select the one that best suits you. This buying guide will cover all the essential information for you if you’re interested in learning about the variables that should be taken into account when purchasing a new gas tankless water heater.

Fuel Type

You must first choose a water heater for your home from either propane or natural gas. When compared, both natural gas and propane function admirably as fuels. Natural gas, on the other hand, is somewhat more affordable than propane and is better for the environment. Contrarily, because propane burns at a slower rate than natural gas, you won’t need to buy as much of it overall.

This explains why propane is the fuel of choice for the majority of portable water heaters. While natural gas is the fuel used by gas water heaters, which are best for household use. The majority of heater alternatives, meanwhile, provide two distinct types, one powered by propane and the other by natural gas. You are free to select the option that best meets your preferences or needs.

Max Power Output

Next, you should look up the gas’s maximum power output to determine its actual strength and how quickly it can heat water for you. Gas water heaters typically measure their heat combustion rate in BTUs/Hr. Although the available options for portable water heaters are typically not very powerful due to obvious reasons, they typically deliver a maximum power output of 41,000 BTUs/Hr, which is considerably less than water heaters used in homes.

When it comes to water heaters intended for home use, there are a variety of models available with varying maximum power output. According to one rule, purchasing a strong heater that can heat up more water to accommodate several people is a good idea if you have a large family.

Water Flow Rate

Generally speaking, water heaters with high power output can deliver hot water at high flow rates. To be more practical, a water heater option that distributes water at a flow rate of 5–10 GPM should be used if you have a large household. GPM, which roughly translates to “gallons per minute,” indicates how much water the water heater can heat in a minute.

A typical shower head provides 1.5 GPM of water flow, allowing you to utilise several showers and faucets simultaneously. However, they are typically not very powerful and can only accommodate a small number of people at once if you’re looking for portable gas water heater options for your RV trailer.

 Ventilation

Since gas water heaters burn fuels, a lot of steam and hazardous gases are released from the appliance. Therefore, if you are purchasing a water heater to be installed indoors, you should be concerned with the proper ventilation, and depending on the water heater you select, it might cost you a little extra.

On the other hand, less powerful water heaters found in RVs are typically built with ventilation in mind, reducing the stress on the user. A few gas tankless water heater solutions are put outside the house, so they also relieve you of the responsibility of ventilation.

Warranty

Since everyone typically purchases a water heater for long-term use, you should not overlook checking for the warranty. Having said that, you should only get one from well-known and respected manufacturers because they offer superior after-sales services. The majority of the water heater solutions on our list are covered by respectable warranties, so if anything goes wrong, you can easily get them fixed for no cost to you.

In conclusion

That’s it; the list of the best gas water heaters currently on the market is complete. Every reader should be able to discover a suitable solution from the list of nearly all types of water heaters intended for indoor and outdoor use.
