Application of Microporous Board in Heat Storage Electric Heaters

Clean and Economical Heating with Heat Storage Technology
Based on the experiences of many major cities worldwide, it has been demonstrated that the fundamental solution to improving air pollution is to change the energy structure. In pursuit of this goal, people have conducted numerous explorations.

Heat storage electric heating technology stands out as a relatively successful experiment. Its principle involves electrically heating the heat storage medium during the storage phase, allowing it to absorb heat and raise its temperature. The heat storage medium is then insulated to preserve the stored heat. During the release phase, the temperature of the heat storage medium decreases, releasing the stored heat.

Experts have compared the use of heat storage electric heaters with centralized urban heating systems, taking into account factors such as equipment investment, heating performance indicators, operating costs, maintenance expenses, and depreciation. The conclusion drawn is that the heating costs of heat storage electric heaters are significantly lower than those of regular electric heaters. When considering energy-efficient buildings, the cost is lower than the standard for centralized heating systems in urban areas, with savings of approximately 26% per square meter of building area for a heating season.

Principles and Characteristics of Heat Storage Electric Heating

Heat storage electric heaters operate by charging during off-peak electricity hours, typically during the night, converting inexpensive electricity into stored heat. The stored heat is then released during peak hours, providing continuous heating for 24 hours. This approach aligns with the “peak shaving, low-peak storage, halving electricity costs” concept.

The core components of a heat storage electric heater include heating elements (heating tubes), heat storage bricks, insulation materials, and a temperature controller.

Microporous Board: An Ideal Insulation Material
Microporous insulation product is a high-efficiency thermal insulation material made by directly pressing nanophase silica dioxide with suitable additives using a special dry pressing process.

Due to their special nanoporous structure and the synergistic effect of various additives, microporous insulation product can significantly inhibit heat transfer, convection, and radiation across different temperature ranges. As a result, they outperform traditional insulation materials like mineral wool, perlite, insulating bricks, calcium silicate, and ceramic fibers, and even surpass products like aerogel felts. In most temperature ranges, the thermal conductivity of microporous insulation product is even lower than that of static air.

Our MIP-800 Microporous Board is an ideal insulation material for heat storage electric heaters. The characteristics of MIP-800 include:

Advantages of MIP-800 in heat storage electric heaters:

  1. Exceptionally low thermal conductivity across different temperature ranges, providing maximum protection for stored heat in heat storage bricks.
  2. Due to its ultra-low thermal conductivity, the insulation material can be made very thin while achieving the same insulation effect, offering favorable conditions for lightweight and compact heat storage electric heaters.
  3. MIP-800 is an environmentally friendly and non-combustible material that does not emit any harmful substances during use and has a permanent service life without external damage.
  4. The material is cost-effective, providing long-lasting, green heating with no pollution or noise.

Therefore, when manufacturing an ideal heat storage electric heater, the selection of insulation material should not be overlooked. MIP-800 nanoporous insulation board stands out as the most ideal material.

For optimal thickness selection of MIP-800 based on the heat storage characteristics and usage of various heat storage bricks, calculations and optimizations are required. Please contact our sales engineers for assistance.
