A Scottish (UK) SME active in the development of heat storage batteries, has developed and patented a unique system which uses excess electricity from a solar PV array to store heat which can then be used to heat mains hot water without the need for an immersion heater tank. The company now seeks PV manufacturers, installers or self consumption energy system suppliers for commercial agreements with technical assistance.
Responding to the need for low to zero-carbon heating, cooling and hot water systems in both domestic and commercial Heating, Ventilation and Air Conditioning (HVAC) applications, a Scottish (UK) SME has developed and patented high power heat batteries using phase change materials. These modular heat energy stores can be stacked to create thermal energy stores with different applications either in domestic, light commercial or large community or commercial scale heat storage.
The Heat Batteries are novel, high-efficiency heat energy stores:
• 4 to 16 times smaller than hot water thermal stores
• Deliver space heating and hot water on-demand.
The company's PV-compatible system uses excess electricity from a Solar PV (photo-voltaic) array to store heat which can be used to heat mains hot water. The hot water will then either be used directly by the customer for hot water or wet radiators, or as a preheat to a combination boiler.
The company now seeks PV manufacturers, installers and distributors to market, integrate and install the systems into solar PV arrays and combination boiler systems. The Scottish company will be available for second level technical support.
The system is currently unique as no other PV driven hot water system is compatible with a combination boiler central heating system.
The system provides a low carbon solution for heating hot water from electricity which would be otherwise exported into the electrical grid for no financial return.
This system connected to an average PV system could save a considerable amount from the customer's energy bills.
