In this buying guide, we see the best gas water heaters on the market and how to choose the right model to buy according to your needs and home.
LPG, CNG, or Propane can power different gas water heaters. First, the gas generates the flame needed to heat the water. Then, the ignition of the flame takes place through piezoelectric ignition.
This system makes gas boilers much cheaper than electric ones because gas is lower than the cost of electricity. Furthermore, the electricity required for ignition is very minimal, so much so that some models of water heaters can be powered with simple batteries.
In addition, unlike boilers, the gas water heater must not be subjected to mandatory maintenance. However, it is advisable to periodically check the efficiency of the drain pipes, both for our safety and for the correct operation of the appliance from the point of view of efficiency and consumption.
To understand the best gas water heater that fits our home, we have to consider several characteristics, such as its capacity in liters, footprint, and the possibility of installing the water heater inside or outside the home. Of course, the price also affects our choice. Let’s see in detail what are the most important characteristics to take into consideration.

How to choose a gas water heater: Types and Characteristics
When choosing the gas water heater, the main distinction between water heater types is between the instantaneous and storage water heater. Besides these, there are other important characteristics to evaluate. Let’s see them.
Instantaneous water heater
The instant gas water heater is among the most widespread. Every time we open a hot water tap, the water pressure inside the boiler decreases, and the pilot flame lights up. Within a few seconds, the hot water reaches the tap. This method proves to be the most convenient because it translates into energy savings and, consequently, savings on electric bills.
It is also an ecological choice because we consume only the necessary gas for hot water. Another advantage of an instant water heater is the continuous availability of hot water, making it suitable for single and large families. If we need more hot water, we can choose instantaneous water heaters based on their flow rate expressed in liters per minute.
Capacity
In the gas water heater’s choice, we can check the flow rate of the liters per minute that the water heater can deliver. Depending on the model, we will have 11, 14, or 17 liters per minute, etc.
A greater flow is important when there are more bathrooms in the house or in any case; we need hot water simultaneously in two different places, for example: for a shower and washing dishes. Therefore, it is also useful to check a minimum flow rate for greater efficiency.
Pressure decreases, giving the instantaneous water heater ignition. If the tap’s water is too little, it may not light up. Instead, the best gas water heater should be activated with small amounts of water, so in the purchase, we can verify that they can work even with a flow rate of fewer than 2 liters per minute.
Accumulated water heater
The storage water heater consists of a tank. The water inside is heated and kept constant, thanks to a thermostat. The operation is very similar to that of an electric water heater, with the difference that the gas has a lower cost. When choosing this type of water heater, you must evaluate the liters needed. There are water heaters of 50, 80, and 100 liters.
The more people there are at home, the more hot water is needed during the day. The advantage of this type of water heater is the constancy of temperature. Even when more taps are opened simultaneously, the hot water gets to the tap faster than instantaneous water heaters.
Another distinction between water heaters is the type of room. This can be open or closed and can significantly affect the price.
Open-air water heater
The cheaper option between the two options includes an open room. With this method, the water heater immediately takes the air outside the appliance. For example, if it is installed in the bathroom, it will take air from the room. Then, during operation, the exhaust pipe will expel the fumes outside.
For these features, indoors. The current regulations indicate precise safety measures based on the room’s cubicle and water heater exhaust pipes. Before buying it, check that it is suitable for indoor or outdoor installation. In some cases, inserting it in too small bathrooms will not be possible.
Watertight water heater
A gas water heater that works with a sealed chamber has the peculiarity of taking air from outside the home and emitting exhaust fumes. This method is considered safer because it avoids putting the domestic environment in contact with the appliance’s ventilation system.
Precisely for this reason, the sealed chamber water heater is allowed both outsides and inside the house. The cost of this type of water heater is higher.
