What Is A Tankless Water Heater, And How Does It Work?

Modern-day technology has revolutionized many applications. Most importantly, it has played its role in making our household life a lot better. Every day there is an addition of a new appliance to make daily living activities easier.

One of such appliances is a tankless water heater, also known as an instant water heater or an on-demand water heater, which is an appliance used to instantly turn cold water into hot water for daily use. It is an excellent long-term investment.

What Is A Tankless Water Heater?

Unlike the traditional geysers or water heaters, a tankless water heater does not require a storage tank to keep hot water on standby. Instead, they only provide hot water on demand instantly.

That is why they are also called demand-type water heaters or instant geysers. They’re connected with the house’s plumbing system and turn on instantly only when hot water is required.

Tankless water heaters save a lot of time, i-e first, wait for traditional water heaters to heat the water and then consume it. It is a good investment, but before replacing your outdated heater, you should get familiar with using an instant water heater and see if it is feasible.

What Is A Tankless Water Heater Flush?

Flushing a water heater is the same as what it seems from the name. A tankless water heater is sufficient on its own and does not require maintenance now and then. However, like all other appliances, it also requires proper flushing, which is essential to ensure no plaque buildup.

The process of flushing is uncomplicated and usually requires 1-2 hours for completion. Flushing once a year is enough to keep the tankless water heater clean, but if your area has hard water, you might want to do it more often.

The process of flushing completes step by step. It is different from tank water heaters, and before you start the procedure, you’ve to make sure of certain things. Check for the flush valves if they are installed or not.

If not, you’ll have to call a plumber and get the valves installed. Also, you’ll require a 5-gallon bucket, a set of dryer hoses, a submersible pump, and 3 gallons of vinegar.

Perform the following steps to flush a Tankless Water Heater:

• Make sure the flush valves are installed.
• Extinguish electric or gas supply.
• Switch off the water supply and check the valves.
• Scrub the filter and make it clean.
• Put the vinegar into the 5-gallon bucket, submerge the pump and connect the hoses from the pump to flush valves.
• Flick on the pump and allow it to run for 90 minutes.
• Switch off the pump and unplug the hoses.
• Put on the electric and gas supply.

What Is A Condensing Tankless Water Heater?

Condensation is the process of changing matter from the gas phase into the liquid phase. Water condensation means the transfer of water from steam into liquid; it is the basic condensation phenomenon.

Tankless water heaters also come with or without a condensation unit. If you have a condensing water heater, your installer should have added a drainage unit. The tankless water heater does not leak at all. Instead, it goes under the process of condensation, for which the drainage unit is required.

In a tankless water heater, the combustion process superheats the water, converted into water vapors due to high temperature. When cooled down to a low temperature, these water vapors make the condensate, i-e the process of condensation occurs.

Suppose you see that condensate is building up in your water heater. In that case, it is not to worry about because most heaters have a drainage unit installed in them.

Do Tankless Water Heater Work With Propane?

Tankless water heaters work efficiently with propane gas. They provide a limitless water supply, about 200 gallons of hot water per hour, on average. A propane heater may cost a bit in the beginning, but it is super helpful, and the money pays off itself when you save over other water bills.

A propane tankless water heater takes up a smaller area. It can be installed on any wall, interior, or exterior of the house. It is much helpful compared to the outdated water heaters that take up a lot of space in the garage or storage rooms. The propane heater ensures an endless supply of hot water day and night for the family’s usage.

You do not have to agonize about running out of water; it can fill up a hot tub and still have enough water left. The most significant advantage is less power consumption. The propane tankless water heater requires much less energy than a traditional tank heater. Therefore you can save up on the power bill.

How Does a Tankless Water Heater Work In An RV?

A tankless water heater works coherently in an RV. An RV water tank usually has 6 gallons of tank space to store water. These 6 gallons of water are quickly consumed, and then the consumer has to wait for the water to heat up and use.

Therefore, it is essential to have a better water heating system, and tankless water heaters are the go-to option.

The motivation for using a tankless water heater is the continuous supply of hot water available for the family to use. As the tankless water heater works on-demand, it will provide hot water, and the household will not lack hot water unless they run out of water.

Also, it saves space, has a lesser weight than the tank water heater, and requires less electricity consumption. So these factors make it appropriate to work in an RV.

How Does A Tankless Water Heater Works With A Water Softener?

If your area has hard water, the chances are that your tankless water heater might build up mineral residue and scale in it. The buildup reduces the life of tankless water heaters and also requires much more maintenance annually.

Even if the tankless water heater does not have a tank to store water, it still supplies water through all the pipes and plumbing systems in the household. That’s why hard water can cause problems.

For avoiding mineral and scale buildup, water softeners are used in water heaters. These water softeners work by swapping sodium ions with calcium and magnesium ions, turning the hard water into soft water.

The exchange procedure involves Polystyrene beads that work by the chemical mechanism i-e positive charges attract negative charges and vice versa.

If you do not use water softeners in your water heater, there may be inevitable consequences. The households that deal with hard water might get skin allergies, bad tasting water, yellowish stains on clothes, and high water bills.

So to avoid these unfortunate things, it is essential to use water softeners with tankless water heaters as it also improves the heater’s life and saves electricity.

Does A Tankless Water Heater Work Without Electricity?

No, a tankless water heater does not work without electricity or a proper power supply. These tanks usually do not entirely depend upon the electricity to work. But the control panel of a tankless water heater requires electricity.

Also, the natural gas or propane heaters do require a power supply to function. If you have to use hot water in a power outage, you might need the traditional water heater installed in your home.

Many households have water removal systems powered by electricity, so in that case, as well, they won’t work without electricity.

Does a Tankless Water Heater Work Without Power?

As described above, a tankless water heater constantly requires an adequate power supply for its proper functioning. These instant geysers have built-in panels/machinery that does not function during a power shortage.

Conclusion

It is concluded that the on-demand water heaters are a great household appliance and provides an unlimited supply of hot water 24 hours a day. A tankless water heater saves you from the trouble of waiting for the water to heat and then to consume.

It covers less space and can be installed on any wall of the house. They require less electricity consumption compared to other water heaters. So it is a good investment which proves fruitful in the long run.
