The very high costs of producing hot water using an electric instantaneous water heater can be reduced by around 75% per year with the photovoltaic off-grid boiler. The photovoltaic boiler is used to preheat water for the instantaneous water heater. The water heater only starts heating when the hot water from the photovoltaic boiler has been used up. This will save you around 600 kWh to 900 kWh per year or €200 to €300.

Use the photovoltaic electricity generated in the balcony power plant to reduce not only your electricity costs but also your hot water costs.

Save up to €450 on electricity costs per year.
