How Does An Indirect Water Heater Work?
Hot water systems such as an indirect water heater are among the most important household appliance in current time. They help in enhancing our experience in a variety of tasks such as showering, washing clothes, etc. But have you wondered how exactly do indirect water heaters work? Well, let us find out.
When asked, most people would say that an indirect water heater uses some kind of electric/gaseous heating technology that directly generates warmth within the user’s water supply. But, that’s not the case. Instead, we get coiled rods placed within a boiler or furnace. Now, the coiled rod is first heated, then brought into contact with the heater’s water tank where it cools off. During this time, heat energy is transferred between the coiled rod and the water in the tank. This process keeps repeating until the desired amount of temperature level is achieved.
Its concept can be compared parallelly to that of an air conditioner wherein heat is sucked from a particular space in order to produce cold. Unlike air conditioners however, indirect water heaters don’t require a ventilation system to operate. That is because the tank in such kind of heaters don’t require the usage of power and can hence be operated using an external source.
How to Use an Indirect Water Heater?
An indirect water heater uses the laws of energy transfer to create hot water. Hence, there is no need for external gas or electric heating sources to make the item function. Install the unit in your basement. A word of caution: make sure that the unit’s capacity is not exceeded by your family or household’s water usage.
Then connect it to your house’s water supply. You can do the whole thing by yourself or could take professional help. After the installation is completed, set up the desired temperature and turn-on any spigot or faucet in your house. You should be instantly getting hotter water.
With this, you can have instant hot water for showering, washing clothes, etc. Numerous fabrics need warmer water, and the indirect heater’s instant hot water supply makes sure to give you that.
What Is the Difference Between a Direct and Indirect Water Heater?
Mainly, the difference between a direct and indirect water heater is its heating unit. Direct water heaters generally use gas or electric heater to do the heating for you. Whereas, an indirect water heater doesn’t require one. Therefore, there is an additional expense with direct water heaters.
Though indirect ones might be a bit cost-effective, this is overshadowed by a direct heater’s efficiency and output. You see, an indirect heater uses the law of conservation fo energy to create hot water. Therefore, there is an increased chance of heat loss as the water travels through the pipes of your house.
Even if fewer parts of an indirect heater is exposed to the surrounding, the energy loss from indirect water heaters is more.
Furthermore, to increase this inefficiency of an indirect heater, you can always purchase a supplementary HVAC system. But this would raise the cost of the complete heating unit.
Why Should You Buy An Indirect Water Heater?
There is no doubt in saying that water heating systems are not just a fancy equipment anymore. They have now become an integral parts of our daily routines. Imagine going for a shower on a cold winter night and not having warm water dropping on your body. Could you possibly get accustomed to such a horror considering the time we live in? I’m guessing the answer is no. But why exactly should you choose an indirect water heater over other water heaters. Let us look at a few pointers.
Since indirect water heaters come with an attached water tank, the user gets ample amount of hot water throughout the day. Adding to that, the boiler equipment that these kinds of heaters run on is also quite large itself. This means that even the production of hot water is quite quick and in large amounts as compared to other types of water heating systems.
As far fetched as it sounds, most indirect water heaters come with a lifetime warranty. That is something no other water heating system provides. However, if you look at it scientifically, it is not impossible for brands to provide such a scheme. As we know, the boilers used for indirect water heaters are made of robust stainless steel. Additionally, they don’t have to withstand a lot of stress in the heating process neither do they have to run for a long time. Therefore, unlike other water heaters the only time they are put under minor stress is when the user demands for hot water.
Since indirect water heaters use external sources for their heating, they are much cheaper than any other heating system upfront. Statistically speaking, you pay about 20-25% of the amount while buying an indirect water heater as compared to when you would buy a tankless water heater. Now, it is worth mentioning that indirect water heaters might not be the best to save money in the long run since they do produce more heat loss comparatively. However, that problem can be dodged by just using your heating system more efficiently.
