eco-spark® for pre-heating

Direct pre-heating

Magen eco-Spark

eco-SPARK

solar collectors are perfect for pre-heating systems. There are two types of pre-heating

systems that eco-SPARK

will provide the most cost-effective solution:

Direct pre-heating

Storage tank circulation system

There are many configurations for these systems; design the system so it meets users' requirements.

Important!

System MUST be designed by a professional engineer.

Important!

Storage of hot water must conform to local health codes to avoid the breading of the

Legionellosis bacteria.

DIRECT PRE-HEATING

The eco-SPARK

system is installed on the feed line before the auxiliary (conventional) heating system. The

principal is very simple: when there is hot water demand and the climate conditions are adequate, the eco-
SPARK

system will turn on and the water will be heated as much as the climate conditions enable. When

there is no demand or when conditions are insufficient, the system will be bypassed.
