Electrical Blog: Advantages and Disadvantages of Storage Heaters: A Comprehensive Overview

Storage heaters have gained attention as an alternative heating solution, offering both advantages and drawbacks that impact their efficiency and practicality compared to other heating systems. Understanding these pros and cons is essential for homeowners considering their installation.


  1. Cost Efficiency: Despite being pricier than gas or oil-based heating systems, storage heaters prove economical when compared to conventional daytime electricity rates.

  2. Continuous Warmth: Unlike some heating systems that shut down overnight for cost-saving purposes, storage heaters provide consistent warmth throughout the night, ensuring a cozy environment in the early morning hours.

  3. Accessibility: They enable homes in areas without natural gas access to still enjoy reliable heating without incurring higher daytime electricity expenses.

  4. Lower Installation Costs: Installing storage heaters is relatively inexpensive compared to setting up gas boilers and radiators or electric heat pumps. This ease of installation is advantageous, especially when renovating older buildings without existing central heating systems.

  5. Minimal Maintenance: Compared to gas central heating, storage heaters involve significantly fewer maintenance costs, making them a hassle-free choice for homeowners.


  1. Heat Loss During Charging: Heat dissipates from the heater during the overnight charging process, resulting in energy wastage as the room remains warm unnecessarily throughout the night.

  2. Inefficient Heat Release: Stored heat is released into the living area the next day regardless of immediate need, leading to wasteful heating when occupants are absent or only at home for short durations.

  3. Limited Heat Supply: The heater solely relies on the energy stored from the previous night, creating problems if the system was switched off or the charge control was set too low. Adjustments must wait until the next day, impacting comfort during unexpected weather changes or late returns.

  4. Complex Controls: Users may struggle with understanding the controls, leading to errors in setting output or boost controls, resulting in increased electricity consumption and costs.

  5. Sizing Challenges: Properly sizing a storage heater involves a delicate balance between cost, available space, and heating requirements. An oversized unit can be costly and space-consuming, while an undersized one may lead to high supplemental heating costs.

  6. Bulky and Heavy: Storage heaters are substantial and take up more floor space compared to other heating systems, potentially impacting room aesthetics and available area.

  7. Electricity Cost Disparity: In most regions, electricity costs substantially more per unit of heat compared to gas or oil, impacting the cost-effectiveness of storage heaters.

  8. Airborne Dust and Allergies: The use of fans in storage heaters increases air circulation and dust levels, potentially affecting individuals with allergies.

Understanding these advantages and disadvantages is pivotal in making informed decisions about implementing storage heaters, considering factors such as cost, efficiency, and user comfort to find the most suitable heating solution for your home.
