Capacity: One of the most important decisions you have to make is the hot water capacity of the heater system. You must purchase a water heater that can heat the amount of water that you need. It would be best if you decided based on your family members and daily uses.

Voltage: That’s another essential factor you must know before purchase. By mistake, many of us order high voltage water heaters though the home service is low voltage, which will create trouble.

So you should first check the voltage supply of your mobile home; after that, you go with the same specification device.

Size: Another thing is the size of the water heater. Understanding the unit’s dimensions as your open space is essential because mobile homes already have insufficient room to fit the device.

If the tank is too large, it will consume more energy. Thus, the electricity bill will be higher. You must make sure that the size of the water heater is appropriate to the size of the tank that you have purchased. If the size of the tank is larger than required, it will take up too much room in the garage.

Cost: The next thing to consider before buying is the cost of the product. The more features you have in the water system, the more you will have to pay for it. So, if you calculate all these factors, it will not be hard for you to decide.

You also have to consider the cost of maintaining the water heater. It’s important because you may have to spend a lot on its maintenance if you use it for a long time. In addition to this, there may be some parts of the equipment that wears out very fast. Therefore, if you want to save on your maintenance expenses, buying a brand new water heater would be best.

Warranty: When purchasing 20 gallon hot water heater, you should check the warranty of that unit. There are different types of warranties available for these products. When considering this factor, it is important to see that you purchase a service contract covering repair and replacement costs for the period specified by the warranty.

Some manufacturers stipulate that you have to use only their approved service center for the warranty period. Thus, you may not be able to use other service centers that may not have the manufacturer’s approval.
