Types of water heaters available on the market

There are different types of water heaters available for purchase on today's market: natural gas or propane/butane models; electric models; and the more modern models known as "condensing water heaters". Each type has different characteristics that should be considered when choosing.

Gas water heaters are the most common and popular. They work by burning gas to heat the water. They are very efficient and have a lower cost of use compared to electric models. In addition, gas water heaters have a large heating capacity, which makes them ideal for larger families or homes with a higher demand for hot water.

Electric water heaters, on the other hand, work by heating water using electric resistors. They are easy to install and don't require an external fuel source such as gas. However, they tend to consume more electricity than gas models, which can result in a higher electricity bill.

Condensing water heaters are considered the most modern and efficient on the market today. They use the heat generated during the condensation process of the gases resulting from the combustion of the gas to heat the water even more. This makes these models extremely economical and environmentally friendly.

Capacity and power: how to choose the right model for your home

When choosing a water heater, it's important to take into account both the size of your home and the number of people who will be using the hot water on a regular basis. This information is key to determining what capacity the appliance needs.
