Page 3: Preface
ELECTRAflow may be notifiable to the relevant building control.) Handling & Storage It is important the ELECTRAflow is handled with care and stored the correct way up in a dry place at all times prior to, during and after installation. -
Page 4: What Is A Thermal Store
Design The copper ELECTRAflow Thermal Store is a bespoke primary store that is very well insulated to ensure minimum Heat Loss and optimally designed to meet the stringent requirements of ERP. In addition, the rectangular tank variant will hold 25% more water than a cylinder in a given space, and the dimensions can be altered to make the best use of the available space. -
Page 5: Mains Water Supply
15mm if there is adequate pressure and flow rate. • The ELECTRAflow will operate with a minimum incoming mains pressure of 1.0 Bar and a minimum flow rate of 10 Litres/minute. Careful consideration should be made to ensure the pressure of hot and cold supplies are balanced. -
Page 6: Water Treatment
Combination chloride/sulphate: Max. 300 mg/l (in total) The ELECTRAflow is part of the primary system and other parts of the primary circuit will require the application of a protective scale and corrosion inhibitor such as Fernox to ensure adequate protection. This should avoid having corrosive material in the primary system and remove any build-up of sludge which can reduce the performance of the High Efficiency Heat Exchanger Coil. -
Page 7: Pipework
• The cold feed from the main incoming stop tap to the ELECTRAflow should be run in 22mm pipe. The cold main and hot draw-off should also be run in 22mm as far as the branch to the bath tap. -
Page 8: Showers
A flow restrictor may be required in the shower outlet hose. • The hot water supply to a shower-mixing valve should be fed wherever practical directly from the ELECTRAflow or be the first draw-off point on the hot circuit. •... -

The mounting holes are located directly behind the enclosure lid screws. The drawing above shows the location and fixing centres of the holes. The Controller should be located in close proximity to the cylinder in a position where it will remain dry.
- Page 17 Issue 6 07/04/2022 Controller Wiring Diagram The supply circuit for each heater group should have an independent connection to the power distribution equipment and be protected by a suitably rated HRC fuse or circuit breaker. An appropriately rated isolation switch (minimum contact air gap of 3mm) should be used close to the control.
