Check each factor and keep in mind the requirements of yours. Then go the list mentioned above and buy the best water heater.
Type of Water Heater
There are different types of water heaters like Storage Tank, Tankless, RV, Solar, Electric, Gas Water Heaters. If you want to go for a lower cost, then you can choose the Storage Tank type. It keeps anywhere from 20 gallons to 80 gallons of hot water ready to use. If you want the hot water on demand, then you can consider the tankless water heater. It provides hot water whenever you need it.
If you want natural products, then you can go for the Natural Gas water heaters. For that, you need a natural gas service to your home. If you are not having, you need to consider extra installation costs for running a gas line. Solar Water heaters are the other type of heaters that use solar energy and saves your money as well. As sunlight can be unpredictable, you can choose this type of heater if needed.
Next, you need to consider is Size. If you have chosen the Storage Tank type, then look at the number of gallons it can supply each hour. This depends on the size of the tank, the size of the heating element, and the source of heat. Based on your family size, you need to estimate how much water you and your family use daily. Then take that estimated value as the minimum number of gallons and choose the correct one.
Generally, water heaters need electricity to run. Standard 115 volt service for the ignition system required in the case of the Gas heater. And some heaters just plug into a convenient outlet. 240-volt service is required for Electric heaters, including tankless heaters. Also, they need a dedicated line that is rated sufficiently to handle the current draw. So, these are the electrical needs you need to consider.
Not all heaters come in equal size. They vary in diameter and height, and you need to make sure whether you have enough space for the product you choose. Generally, for storage tank-type heaters, the size varies based on the capacity. Also, some heaters require a certain amount of air surrounding them. So, based on that, you need to plan for appropriate space. Some may come taller, and some come wider. Before buying, check the specifications, and then buy.
This needs to be considered if you are going for the Gas Water Heaters because they have to be vented to the outside. This is handled in many ways. It is better to take the help of the licensed plumber to get venting done adequately and safely. Even when you are replacing the present heater with Gas heater, you need to take licensed plumber help because, since your last installation, the local building codes might have changed.
These Digital Displays help you to monitor the water levels, and you can easily know the status. When the water is heated, it automatically indicates you. In Solar heaters, the displays help you to know the tank and collector temperatures, pressure readings, and others. In some electric heaters, you can set a vacation mode. When you are away, it uses the heat pump for more efficiency.
It is better to check the warranty before buying any device. For water heaters, the warranty runs from 2 to 12 years. For longer warranty models, you need to pay a bit more because, based on the quality and features, the price increases. They use larger burners or elements to speed up the heating and also have thicker insulation, which leads to less heat loss. So, if possible, choose the Water Heater with the longest warranty.
The water capacity of a water heater is how much it can heat up and store at once. This is mostly for water heaters that have a tank for storage. A good water capacity directly means more hot water at your disposal at once.
The flow rate in a water heater is the flow of the water that comes out. This has to be balanced as too much will disturb the mechanism, and too little will result in slow water output. It is usually measured in PSI, which is what you should look for.
The power output of a water heater determines how quickly the water gets heated up. Good heating speed means that you will have hot water quickly, and it’s the prime feature that should be looked ta in a tankless water heater especially.
Deciding on the Size of a Water Heater
With tankless water heaters, you don’t really need to determine size because they are designed to provide water continuously. The number of points they can cater to at once is what is important. As for conventional water heaters, the capacity is measured in gallons. This capacity can be measured based on the number of people there are in the family and what you need for the number of members you have.
- 1-2 people: 30-40 gallons
- 2-3 people: 40-50 gallons
- 3-4 people: 50-60 gallons
- More than 5 people: 60-80 gallons
Draining a Water Heater
When you use an appliance like a Small Water Heater regularly, it is obvious that hard water and sediment will accumulate over time. This should be done annually, as suggested by most brands. This should be done stepwise and carefully.
