Boilers

Types of hot water storage tanks

• Coil storage tanks: Primarily used in centralized heating systems, these tanks contain an internal coil through which hot water from the boiler circulates. This method allows for efficient heating of domestic hot water.
• Heat pump storage tanks: These tanks use energy from the air or ground to heat water, offering a highly efficient and sustainable option. They are ideal for reducing energy consumption and CO₂ emissions.
• Solar storage tanks: Integrated with solar thermal panels, these tanks utilize solar energy to heat water, representing an eco-friendly and cost-effective solution. They are particularly suitable for areas with high solar exposure.
• Electric storage tanks: Often used in residential applications, these tanks heat water using electric resistance elements. They are easy to install and can serve as a secondary or backup heating system.
• Gas storage tanks: These devices use natural gas or LPG to heat water, providing an efficient and relatively economical option. They are ideal for homes connected to a gas network.

Importance of energy efficiency

The energy efficiency of hot water storage tanks is essential for reducing operational costs and environmental impact. Here’s how each type contributes to improved efficiency:

• Coil storage tanks: Utilize heat already produced by the boiler, optimizing overall heating system efficiency.
• Heat pump storage tanks: Can be up to four times more efficient than traditional storage tanks, significantly lowering energy costs.
• Solar storage tanks: Provide almost free energy once installed, reducing reliance on fossil fuels and greenhouse gas emissions.
• Electric storage tanks: Although less efficient than other solutions, they can be programmed to operate during off-peak electricity hours.
• Gas storage tanks: Offer high efficiency due to clean gas combustion, with rapid water heating capabilities.
