Power Diverter Savings Calculator

Estimated Yearly Savings:

Estimated Return on Investment Period in Years: 

Please note that this estimate is provided for guidance only, as we do not have the specific details of your installation. Therefore, we cannot guarantee these savings.

Our Estimation Model

This estimate is based on assumptions that reflect typical conditions and average statistics from the UK. Please note that actual results may vary depending on specific geographic and climatic conditions.

Our Assumptions:

  1. Water Heating Requirements: We estimate that each liter of water requires an increase in temperature of 45 degrees Celsius to reach typical usage conditions. This corresponds to an energy requirement of 0.001163 kWh (1.163 Wh) per liter per degree Celsius increase.

  2. Solar Production and Non-Production Days: We anticipate that there will be 165 days per year when no energy is exported due to suboptimal generation conditions and self-consumption of the generated power.

  3. Daily Generation on Sunny Days: On days with sufficient solar generation, we estimate that each kW peak of your solar installation will produce an average of 3 kWh per day.

  4. Export Potential: We assume that 50% of your total solar PV generation is surplus on 200 days a year when generation exceeds local consumption. This surplus energy would typically be exported to the grid, though the exact amount may vary with your daily energy usage and seasonal variations.

What Our Customers Say




We fitted one of your PowerFlow units as a result of a visit to discuss power-saving measures with someone from Greenshop Solar. This was over a month ago, and as a result of the surplus energy that would have gone to the grid being diverted to our immersion heater, we have not had to use our gas boiler for water heating since. In addition, we have much more and much hotter water available. Fitting was quickly completed by Tim, which is all very compact and does not involved any major works and a very minimal amount of cable. We would strongly recommend this unit to others who have solar panels.



Excellent money saver

The PowerFlow ERS Mini monitors your main incoming power cable, your side of the meter. It detects any exported power from your solar panels and diverts the major part of that power to (in my case) the electric immersion heater in my hot water tank. So far, I have had access to hot water for over a month and have only used mains power on two occasions, thus saving on the cost of water heating. My daily consumption has fallen from 8kWh to under 3kWh per day.



I've not used the gas boiler for water heating since

E.R.S has fit seamlessly into my setup and is running with my battery storage. I now have lots of energy control that I was previously lacking. A brilliant product.

Peace of Mind Guaranteed

If you're not happy with your product for any reason, you can return it within 2 months hassle free. If your product fails under warranty, we will repair or replace it.
