Benefits of Tankless Water Heaters

If you’ve been wondering if a tankless water heater is right for your residence, you’re in the right place. There are many amazing benefits to switching to a tankless system; there are also a few drawbacks you should consider before buying. To find out how you can benefit from installing these systems in your home, we present the following:

They Don’t Take Up Much Space

They don’t require nearly as much space. Because they require less space, you can install your tankless water heating unit that’s a smaller unit in sink cabinets or larger units in a closet tank full of heated water, you aren’t limited by the size of the tank and limited to where it can go.

Highly Efficient

They’re highly efficient. In many settings and situations, tankless units are more efficient than tank-style systems. This is primarily because they don’t experience heat loss through the walls of the tank.

Clean Systems

Tankless water heaters are shown to be very clean. Although water heating systems that use tanks are prone to rust and scale accumulation, tankless water heaters bypass that problem altogether.


Tankless water heaters come with more extended equipment warranties. In general, tankless systems last longer than other types of water heaters, so manufacturers can afford to offer a more extended warranty.

How Tankless Water Heaters Work

On-demand water heaters are growing in popularity because they are more energy-efficient. Heating and storing a large tank of water consumes extra energy, which means tank systems will create higher operating costs. Users will find that there will be more energy savings the more water that is actually used, and they will save even more in their energy costs if they install a unit for every hot water outlet. However, these systems cost more to buy, but they also have lower operating costs and have a longer life expectancy. It seems that homeowners can save with these in the long run.

Installing your unit is best done by a professional.

Why don't I have hot water?

Before troubleshooting a gas water heater, check if the gas is adequately supplied to your house and your water heater; there might be obstructions, shortage, or the main gas valve is closed. If hot water suddenly becomes cold, the water usage might have been exceeding the tank capacity. If that is the case, wait for the water heater to recover. Call us right away!

What size water heater do I need?

Traditional water heaters have long been considered the better choice for large homes. However, not all tank water heaters come in the same shape and size. If you have a large family – say four or more – you will want to install a water heater with a tank that can hold between 50 and 80 gallons of water at a time. On the other hand, if you live in a small home with only one other person, you will probably be better suited to a unit that holds 23-36 gallons. If you’re looking to install a tankless water heater, conversely, the size of the unit is less important than the system’s flow rate (another advantage of tankless water heaters is that they are always fairly small, and therefore relatively easy to access.) A tankless heater’s flow rate is measured in gallons per minute or GPM. The bigger your home is, the higher GPM your tankless system will need to have.
