IVAR.ASKO HEAT AHR-B-C-9,0 electric immersion heater – 9.0 kW, 3 × 400 V, L = 750 mm
Code: IVA012-0407Product detailed description
Supplementary heating in the tank
The IVAR.ASKO HEAT AHR-B-C-9,0 is the most powerful model in its range: 9.0 kW at 3 × 400 V AC. It consists of three U-shaped heating rods made of Cronifer 1.4529 (Ø 8.2 mm) welded into a brass boss with a 6/4" tapered male thread. The immersion length is 750 mm, of which the first 150 mm from the boss is unheated, reducing scale build-up in the tank socket. The low surface load of 8–9 W/cm² works in the same direction.
Control and protection
- electromechanical thermostat to EN 14597, adjustable from the frost protection position to approx. +85 °C
- +110 °C safety cut-out with lock-out, manual reset only after cooling by approx. 10 K
- integrated contactor, ON / OFF / AUTO switch and LED mode indicator
- in AUTO mode heating is enabled by a 230 V signal, for example from a heat pump
- impact-resistant polycarbonate covers, IP41 protection, dry-firing protection
Use and installation
The heater is suitable as back-up or supplementary heating alongside a heat pump, solar thermal system, photovoltaics or wood, oil and gas boilers, and as frost protection. It must be installed horizontally only, with the TOP mark facing up; the rods must be fully immersed and a distance of 50–100 mm kept from the inner wall of the tank. The fixed cable connection with all-pole isolation may only be made by a qualified electrician.

Frequently asked questions
Which tank does the 750 mm heater suit?
A vessel with a 6/4" socket in which 50 to 100 mm remain to the inner wall once the heater is fitted. The rods expand by up to 30 mm when hot, so at least 50 mm must be kept.
Can the heater be switched by a heat pump?
Yes, in AUTO mode heating is switched on by a 230 V signal at terminal 2, with which the heat pump enables the supplementary heating. In ON mode the heater runs on its own thermostat.
What should I do if the safety cut-out trips?
The cut-out trips at +110 °C and stays locked out. It is reset with a screwdriver via the Reset button once the temperature has dropped by about 10 K; if it tripped because of a fault, a specialist must check the system.
Can I fit two heaters in one flange?
Not in a flange with two 6/4" sockets spaced 120 mm apart (code Y91A20272) – this heater type is not designed for such double installation.
