TECHNICAL INFORMATION

Electric radiators must be installed in zone 3(B) in any bathroom. They may only be installed in zone 2(A) (or at least 60 cm from the edge of a bath or shower), if the power supply line to the socket is protected by a differential overload cut-out with an intervention threshold not exceeding 30 mA. The power supply socket and the differential overload cut-out must be located in zone 3.

During the summer months when the boiler is switched off, an immersion heater can be inserted into the towel warmer radiators so they can be used to warm towels and linen.

When used in combination with an immersion heater, the towel warmer radiator is effectively transformed into an electrical appliance with a 230 V, 1 ph, 50 Hz power supply, therefore the electrical standards in effect must be fully complied with.

The power of the immersion heater must be selected in accordance with the size of the radiator. The technical data sheet of each radiator indicates the best power for each model. A lower power may be chosen to keep down energy costs. Higher powers would force the internal working thermostat to trigger, which would anyway limit the maximum thermal power the radiator would be capable of dissipating into the environment. The immersion heater must be installed vertically in one of the side manifolds; this is the only way to guarantee that the entire radiator warms up evenly after about 20-30 minutes.

All the radiators with central connections and a 50 mm connections centre feature 1/2” bores on the bottom of the side manifolds where it is possible to easy insert an immersion heater at any time.

In order to install the electric heating element in products without 50 mm central connections on the lowest pipe (see the figure at the side), IRSAP proposes the use of special valves and lockshields that offer the chance to insert the electric heating element through the valve casing without changing the hydraulic connection in order to ensure normal operation in both hydraulic and mixed modes. Valve and lockshield code: VALKITSQMIST in white (code 01) or chrome-plated (code 50) finish.

“A” quota for IRSAP angle pattern valves and lockshield valves = 40 mm
