Tankless & Hot water heaters

When deciding between tankless and tank hot water heaters, it’s important to understand the key differences, advantages, and disadvantages of each type.

ASM has created comparative overview:

​

Tank Hot Water Heaters

Description: These are traditional water heaters that store a specific amount of hot water in a tank. They continuously heat the water to maintain the set temperature.

Advantages:

1. Lower Initial Cost: Generally, tank heaters are less expensive to purchase and install than tankless models.

2. Simplicity: They have a straightforward design and are easy to maintain.

3. More Capacity: Ideal for households with high hot water demand at peak times (e.g., multiple simultaneous showers).

Disadvantages:

1. Limited Hot Water Supply: Once the tank is depleted, it takes time to refill and heat again.

2. Higher Energy Bills: Constant heating of stored water can lead to higher energy costs due to standby heat loss.

3. Larger Footprint: These units require more space due to the size of the tank.

4. ​

Tankless Hot Water Heaters

Description:  Also known as on-demand water heaters, tankless or instantaneous heaters and they provide hot water only as needed, heating the water directly without storing it.

Advantages:

1. Endless Hot Water: Provides a continuous supply of hot water, as long as the demand does not exceed the unit's capacity.

2. Energy Efficiency: Typically more energy-efficient since they only operate when hot water is needed, leading to lower energy costs.

3. Compact Size: Takes up less space and can be installed in smaller areas.

Disadvantages:

1. Higher Initial Cost: More expensive to purchase and install than traditional tank systems.

2. Limited Flow Rate: May struggle to supply hot water to multiple outlets simultaneously if the flow rate exceeds its capacity.

3. Maintenance: May require more maintenance and descaling, especially in areas with hard water.​

Conclusion

• Choose a Tank Heater if your household requires a large amount of hot water at once and you prefer a lower upfront cost.

• Choose a Tankless Heater if you want energy efficiency, an endless supply of hot water, and can accommodate the higher initial investment.
