Compared with other direct-heat electric boilers and direct-heat electric heating equipment, regenerative electric boilers are both energy-saving and economical. On the premise of meeting the same heating demand, the daily power consumption of thermal storage electric boilers is the same as that of direct heating electric boilers, because the heat generated per kilowatt hour of electricity is 860 calories.

1. Does the regenerative electric boiler consume electricity?

Compared with other direct-heat electric boilers and direct-heat electric heating equipment, regenerative electric boilers are both energy-saving and economical.

On the premise of meeting the same heating demand, the daily power consumption of thermal storage electric boilers is the same as that of direct heating electric boilers, because the heat generated per kilowatt hour of electricity is 860 calories.

The difference is that all regenerative electric boilers use low-price electricity at night, with electricity prices generally ranging from 30% to 50% of the peak electricity consumption during the daytime and during the power period, while direct heating electric boilers use electricity at any time during the heating process.

Therefore, compared to direct heating electric boilers, regenerative electric boilers consume the same amount of electricity, but their electricity bills are more than 50% lower.

2. How to calculate the operating cost of regenerative electric boilers?

The main cost of using a thermal storage electric boiler is the electricity bill, as the thermal storage electric boiler does not require specialized manual maintenance, only requires personnel supervision, and the labor cost can be almost negligible.

Operating cost of regenerative electric boiler=[Heating area (m2)] × Design heat load index (w/m2) × 120 days (heating days in the heating season) × 8h/day (daily low power time)/1000] * 0.3 yuan/kWh (low local electricity price).

3. Is it suitable to use regenerative electric boilers?

The basic condition for using regenerative electric boilers is to enjoy a low electricity price policy. Generally speaking, if the electricity prices during the day and at night are different, and the electricity prices at night are cheaper, then using a thermal storage electric boiler is very suitable.

The larger the difference between the electricity price in the low valley period and the electricity price in the peak average period, the more suitable for using regenerative electric boilers.
