A water heater is usually in high demand in relatively colder regions, where you need hot water throughout for survival. It is convenient and efficient as it provides hot water instantly whenever you need it.

Types of Water Heater

There are round about five different types of water heaters, all with their own pros and cons. Each type of water heater has unique features that distinguish it from the rest. However, it is imperative to know the characteristics of each heater to decide which one you need. So, let’s go through each type of heater briefly.

1. Conventional Water Heater

It is the oldest and most popular type of water heater. It is mainly connected to a water tank, through pipes, where the hot water is stored after being heated. The best part about a conventional water heater is that it gives a spectacular performance no matter where you live. It means that it does not require any special conditions, such as solar, etc., for proper functioning. Moreover, it is a lot cheaper than other alternatives.

It gives instant access to hot water without keeping you waiting for too long. Moreover, you get unlimited access to hot water using a tankless water heater. There are mainly two types of tankless water heaters these days in the market, i.e., those that run on electricity and those that run on gas.

It uses only a tiny amount of electricity to direct the heat from different locations towards the heater.

As you may have already guessed, solar water heaters convert solar energy into thermal energy, which is then used to heat up the water in the tank. A solar water heater basically consists of a roof-mounted panel that has water pipes inside. The solar panel absorbs the solar heat and transfers it to the water in the pipes inside. When the water heats up, it is transferred to the water tank or the reservoir.

Pros

  • Uses renewable resources
  • Excellent long term investment
  • Highly durable
  • Reliable performance

However, they are very much different mainly because a conventional water heater uses electricity or gas to heat up the water. In contrast, a condensing water heater uses exhaust gases from the chimneys and vents and directs them towards the condensing water heater, thus heating up the water within.

Pros

Cons

Comparison Of Types Of Water Heaters

Each type of water heater is different from the other on the basis of qualities and features. For instance, Solar water heaters differ from all other types mainly because it runs on a renewable energy resource, i.e., sunlight.

How To Maintain A Tankless Water Heater

With the passage of time, like any other thing, your tankless water heater may also become polluted with accumulated mineral gunk. And if you want your water heater to keep working at optimal levels, you must get a proper maintenance check at least every year. Tankless water heaters are hailed to be extremely low maintenance, but still, it is open to getting polluted. So follow a few simple steps to clear away all the accumulated minerals from your tankless water heater.

Step #1: Before getting started, unplug your tankless water heater from the power socket to eliminate the risk of possible electrocution.

Step #2: Next, you must turn off the water valves that supply water to the tankless water heater. This step will ensure that no water flows into or out of the heater while you are working on it. Moreover, make sure that you shut off all three valves of the heater for maximum safety.

Step #3: After that, move to the purge port valves and slowly and carefully remove the caps. However, before doing so, double-check the water valves because if they are not tightly shut, hot water will come rushing out of the purge port and may burn your skin terribly.

Step #4: The next thing you need to do is attach the hose lines with the water valves on the tankless water heater. The water hoses may have come along inside the box with the water heater, and if not, you can easily purchase them from any retail shop. However, you must get the correct size of the hoses so that they fit the valves.

Step #5: Once the hoses are tightly attached to the water valves, you can now open the port purge valves.

Step #6: Next, read the draining instructions and procedure written on the user’s manual accompanying the tankless water heater. Try to follow the instruction for the minute details because any miscalculation can lead to permanent damage to your water heater.

Step #7: Use undiluted white vinegar to grain through your tankless water heater mainly because any other chemical can prove to be very toxic to the human body. You definitely don’t want to fill your water heater with chemical radicals.

Step #8: Close the purge port valves once the draining procedure is completed.

Step #9: Next, disengage the hoses from the water valves.

Step #10: Put the caps of the purge port valve back on. Make sure to tighten the caps in place to prevent any possible leakages in the future.

Step #11: Finally, read the user’s manual very carefully for specific details on how to safely restart your water heater after the draining process is completed.

Things To Consider Before Buying A Water Heater

Capacity

Capacity is the first and foremost thing that you must consider while buying a tankless water heater. It is mainly because capacity is directly related to the number of users as well as the daily consumption level. In simple words, the more the users and the higher the consumption level, the greater the capacity heater is required and vice versa. So consider your need first while buying a tankless water heater because you definitely don’t want to run out on a hot water supply on a cold wintery day.

Quality

It is a given that you must check out the quality of the tankless heater before you buy it. However, pay special attention to the water pipes and the body material of the tank because, in most cases, a water heater gets severely damaged by mineral accumulation, especially in the places where hard water is supplied. So as a safety measure, always get a corrosion-resistant water heater.

Safety

Keeping in line with the famous saying, “ Better safe than sorry”, you must purchase a tankless water heater that offers maximum safety features. Safety is imperative to consider while you are buying home appliances because you definitely don’t want your house to burn down. For this purpose, always look for a safety valve in a tankless water heater because it will keep a good balance between ideal pressure and temperature.

Installation Area

Before deciding on a specific water heater, you must consider the space you have available for it. This is because there are all different sizes of heaters available in the market. However, you must get the size that fits your home. This consideration is crucial mainly because a water heater needs to be fixed in a spot with a constant supply of water.

Climate Considerations

Climatic conditions of your region play a vital role in your decision regarding buying a water heater. For example, if you live in a region where you get plenty of sunlight, you must purchase a solar water heater. On the other hand, if you don’t consider this factor, your purchase may turn out to be totally useless. For example, buying a solar heater in colder regions with a high precipitation rate is a huge mistake!
