Standard Elite DHW heating
Standard Elite Operation
Direct heating of a Stnadard Vented Tank
The attached Standard Vented Cylinder Heating with Elite schematic details how an existing our standard method of DHW heating can be used in conjunction with Elite. The stat on the immersion is set to antiscald temperature so the output temperature will be at a safe level. If the tank is heated by Elite then ther oil, gas or electricty heating will not be required to heat the tank instead or it may only have to top up the temperature slightly.
A direct cylinder is not recommended for areas with high limescale content in the water supply. The limescale tends to build up on the pipework of the cylinder and on the element inside, which can shorten the lifespan of that section of the system.
How ELite with Export Isolation functions
In the same schematic the Elite heats the buffer cylinder by monitoring import/export and sending any exportable power into the cylinder. In areas of clustered PV installs in newbuild estates for example the Elite with EC can be used to limit the export to the grid to a set limit by diverting some or all of the exportable energy to the tank. The tank can be sized correctly inconjunction with the peak day of the year output in kWh from the PV panels, the export limit available, daily electricity usage and the daily domestic hotwater requirments to prevent an over export event. If this event should occur the Export Control Isolation Relay will disconnect the inverter for a specific length of time before automatically re-engaging the inverter as per the standard EMMA with export control guidlines.
A Perfect Combination
By combining the Elite with the PV install and the Preheater system the Feed in Tarriff is maintained by keeping the inverter online, the Client uses less fossil fuel to heat their water helping the environment and their pocket and the Network Operator maintains a stable grid safe in the knowledge that exportable power is being put to good use and not flooding the network.
