Go Greener

A key accessory for solar PV or wind generators, PowerFlow's Energy Recovery System (E.R.S) is a true solar water controller designed from the ground up.

By accurately controlling electrical heating loads, such as immersion water heaters or wall mounted space heaters, E.R.S is able to smoothly divert additional solar energy to be stored as heat. It does this by cleverly controlling your existing heating device meaning no other specialist heating equipment is required. Recovering energy in this way results in gas, oil or electricity saving.

The foundation of the E.R.S energy control system is F-POINT technology®, an advanced energy control method designed by PowerFlow's engineers in the UK.

The house below shows how PowerFlow's E.R.S can be easily integrated into an existing hot water system. Thanks to its plug and play system, typical installations take just a few hours by a trained electrician.

Make the most of your home grown energy!

Get Advanced Solar Immersion Heating

During its daily cycle a grid connected renewable generator such as solar PV, produces electrical power based on available sunlight. Due to the very nature of this renewable technology the production of power does not always coincide with the demand.

When energy production is greater than demand the surplus is sent back (or exported) to the national grid where your solar energy is used by someone else. This results in lost savings.
