BIZON - Two zones, wall-mounted electric boiler

from 6 to 18 kW

UNIQUE ! a GRETEL innovation

Specially designed to control two central heating circuits.

Born of a patent (No. FR2828270), the electric boiler BIZON developed by GRETEL is unique and allows direct connection to two channels for independent central heating and optimal control of each zone for comfort and economy.
It is available from 6 to 18 kW. This boiler combines simplicity and reliability with an electromechanical equipement quality, efficient immersion heater on flange and a heater body in stainless steel for corrosion resistance.

2 BOILERS IN 1

Originally designed to equip a low temperature underfloor heating circuit (LT) and a radiator circuit (R), they can also be recommended for control of two areas of the same nature, such as day and night area.
=> two networks radiators
=> two floor heating circuits
=> one network radiators + one floor heating circuit

DIRECT CONNECTION

In the same set, the BIZON consists of two distinct boilers, each adapted to a circuit.This structure allows a connection to each circuit without the use of additional hydraulic accessories. The operation of each heating element is independent and is regulated separately. Just one expansion tank is to install: GRETEL patent.

CHOICE OF POWER

Very interesting, each heater can be equipped with a power of 3, 4, 6, 7.5 or 9kW. The addition of the powers assigned to each zone defines the total power and the reference of the corresponding BIZON.
Example: Radiators area (R) 6 kW / floor heating area (LT) 4 kW Ref. "BIZON10 6R/4BT" (BT means Low Temperature)
