An electric boiler with thermal storage is used during the low electricity load off-peak hours at night, where heat is stored using an electric boiler and solid magnesium-iron bricks as the thermal storage medium. This stored heat is then released during high electricity load times, such as during standard and peak hours, to meet the needs for residential heating, domestic hot water, and reduce operational costs for users. Residential electric boilers with thermal storage are suitable for residential homes, villas, small office spaces, one-story houses, and workshop areas of a few hundred square meters in areas with off-peak electricity rates.
Residential electric hot water boiler with heat storage features:
High thermal efficiency, pollution-free, no emissions, waste liquids, or solid residues, and no noise.
No open flame, low fire safety requirements.
• Easy installation, minimal maintenance workload.
High level of automation, no need for dedicated operation staff.
• Leverage off-peak cheap electricity to reduce operating costs.
• Fully equipped with safety protection devices, reliable in operation.
• Load can be added or reduced step by step, with a smooth adjustment process and high control accuracy.
