2020 Buyers Guide to the Best Gas Tankless Water Heater
Gas tankless water heaters can offer you a number of significant benefits to help you save on your electricity bill and have hot water ready whenever you need it. There are a few factors that you need to consider before you decide to buy a specific gas tankless water heater. Let’s look at some of these important factors.
3 Main Points to Consider:
- Size: The size of the gas tankless water heater you wish to buy will have a significant impact on its compatibility with your house. Before you consider buying one of these devices, you should first consider where you want to use the heater and determine how much space is available to fit the device into. Buying a device that is larger than the available space means you will have to make modifications to the area, which can add additional expenses to the installation of the heater and interfere with existing equipment and appliances that have already been installed in the area you wish to install the device. Remember that additional ventilation and other systems will also need to be installed alongside the gas tankless water heater – adequate space should also be available for these systems.
- Cost: The cost of the gas tankless water heater that you are interested in should also be taken into careful consideration. The prices of these devices vary widely – some devices cost less than $500, while others can be priced higher than $1,000. It is also important to note that the installation of a gas tankless water heater is somewhat complicated – there are additional systems that will also need to be installed. These costs are not included in the price of the heater itself. Consider your budget and make sure that the device and the installation procedure can fit within that budget. Also be sure to take a look at all of your options and avoid opting for a device that provides more features than you require – this would lead to additional costs that you have no use for.
- Capacity: Even though these devices have no tank where water is stored, as they instantly heat water on demand, it is important to realize that you still need to consider their capacity. Not all of these devices are equally powerful. Some gas tankless water heaters may be more appropriate for use in the kitchen, due to a lower capacity. In most cases, the capacity of these heaters tells you how much water the device can heat per minute – this allows you to understand how quickly water can be heated. A faster heating function is needed in cases where the device will be used in a shower, for example, to ensure an adequate amount of water can expel from the shower head continuously.
What are the main differences between electric and gas tankless water heaters?
When interested in buying a tankless water heater, whether a home or RV water heater, one of the first things you will notice is that you can choose between an electric or a gas model. Both of these devices essentially have the same purpose – to instantly heat up water and provide you with on-demand hot water whenever you need it. This is done without the need to hold a tank that contains water and no need for a specific amount of water to be kept heated all the time. There are, however, some differences between electric and gas tankless water heaters. An electric water heater depends on electricity, while a gas heater somewhat depends on a power source such as propane or natural gas. Gas heaters are considered to be a more appropriate solution in areas where extremely low temperatures are present. Ultimately, the final choice between an electric or a gas heater often lies within the personal preferences of the homeowner, as some people are not very comfortable with using gas-powered appliances in their house.
