Quick Checklist on How to Choose the Water Heater Like a Pro
Friday, 08 January 2021

A water heater is a device that is used for domestic water heating. It uses the principle of currents of heat generated by a heat source and then transfers it to heat water. Hot water is used in various ways like cooking, cleaning, bathing, space heating, and industrial use. This article provides a quick checklist on how to choose the heater like a pro. Your water heater can malfunction at any time.

There are various types of water heaters, which include.

Convectional Currents Water Heater

The conventional water heater uses water stored in a tank, which is later heated. Therefore, it means there will be a certain amount of water to be heated at a go. The storage tank should be insulated to heat water. According to Genadi Kahanovich, owner of “Exclusive Furnace and AC Repair in Etobicoke” - In order to control temperature and pressure within the tank, the device has two valves; one to control temperature and the other to handle the pressure. The temperature valve is opened to moderate temperature when it reaches 120°C, while the pressure valves open when the pressure comes to 150 Pascals. It is the most appropriate type of water heater to be used in households. The disadvantage is that it has a specific amount of water to carry. The main benefit of this type is that it is the most affordable and easy to install.
1. Tankless Water Heater
This type of water heater can give an infinite supply of hot water for a home. It has no tank. It has coils that are heated, and in return, they heat water. It is excellent for heating water quickly and in massive amounts. These heaters come in different sizes. Thus, some require large gas lines and electric power supply to operate. This heater's main advantage is that it saves space: That's one less appliance you have to make room for inside. Maintenance of these heaters is difficult because some parts are too small to access.
2. Heat Pump Water Heater
It's power-saving since it does not directly generate heat but uses atmospheric heat and geothermal heat to heat water. Electricity is used to channel heat from the ground or air to water. It needs a relatively large room for installation because of its size. Since it has a tank, it has to be cleaned often to extend its lifespan.
3. Solar-powered Water Heater
The solar-powered water heater uses heat energy from the sun to warm water. This may be the most energy-efficient since it relies on a natural source of energy. The heat trapped from sun rays is transported through a closed system and then heats water in the tank. It's money-saving, particularly during sunny days. It requires a backup of other fuels to run in the absence of sunlight.
4. Condensing Water Heater
This type of water heater needs gas fumes, especially natural gases, in a household for them to function. It uses heated gas fumes from a natural gas system to heat water. It has a tank to store water for heating. These gas fumes are channeled through a coil fixed at the base of the tank to heat water. Thus, little energy is consumed in the process. This water heater uses a tank. Therefore, one will need to buy according to the family size.
The factors to put into consideration when purchasing a new water heater include;

Things you should know before choosing a water heater

1. Guarantee
The guarantee is a period given by the seller to the buyer. If the commodity fails to function, the buyer can return it to the seller for an exchange. When buying a new water heater, one needs to consider a warranty to avoid other costs. We understand that some heaters are expensive to purchase. It feels terrible when a costly water heater malfunctions within a short time. Some sellers offer an 8-10 years warranty while others offer up to 12 years. What we need to choose is an item with a high warranty.
2. Types of Drain Valves
These drain valves are used to drain water from a heater, especially those with tanks. The primary material used for these valves is plastic and brass. When we compare plastic and brass, we see brass is appropriate than plastic. The reason is that brass is more efficient and reliable than plastic, although both are non-corrosive. Brass will not damage quickly as compared to plastic. They have high durability than plastics. Another thing is that brass is not affected by changes in temperatures like plastics do.
3. Scaling Devices
Scales of minerals can damage your device. Therefore, anti-scale devices are needed. This device's function is to move water to the bottom of the tank, making it less prone to mineral build-up. Thus, it increases its lifespan.
4. Glass-lined Tanks
Some heaters have a glass lining on the inside, especially with tanks. This lining helps in reducing corrosion of the water heater; this increases their lifespan.
5. Screen Displays
Water heaters with these screen displays are preferred because of the ease of adjusting your heater settings to fit your requirements. You can easily control the output of the water heater, temperatures as well as pressure. Some displays also enable one to set a time, maybe in hours when the house is filled. This increases its energy efficiency since the water heater will shut off when the set time elapses. Digital displays will show you readings of temperatures and pressure of the water.
6. Carriage Ability
Determination of your heater's carriage ability will be based on the number of people in a family. Sometimes it is difficult to determine since the water consumption of an individual varies greatly. To mitigate this, we can use a simple formula to find out about water usage in your home.
In conclusion, we have seen various types of water heaters, and we have analyzed each one of them. We have seen some are more energy-efficient than others, thus most preferred. The above factors are vital to consider when buying any water heater.
