I ordered the wrong radiator, can I make a return?
You can contact the dealer where you purchased the radiator or, alternatively, our after-sales department
Some parts of the radiator feel cold, what should I do?
First you have to vent the radiator. There is a dedicated section on https://www.irsap.com/en/support-en/irsap-consiglia-3/2096-how-to-vent-radiators.
The radiator makes a strange noise when it is turned on.
If your radiator does not have an even temperature across its entire surface, or the pipes are cold on one side, or you hear a noise when they are turned on, there is probably an air accumulation inside that, like a bubble, prevents the hot water from circulating properly, causing the operating pressure of the plumbing system to drop and sometimes the boiler itself to block. To eliminate this air bubble, it is therefore necessary to vent the radiators. The operation is very simple and quick to perform on the Irsap website.

The radiator does not heat at the top, what to do?
If your radiator does not have an even temperature across the entire surface, or the pipes are cold in the part, or you hear a noise when they are turned on, there is probably a buildup of air inside that, like a bubble, prevents the hot water from circulating properly causing the operating pressure of the plumbing system to drop and sometimes the boiler itself to block. Therefore, to eliminate this air bubble, it is necessary to vent the radiators.

How can I distinguish a manual valve from a thermostatic valve?
To tell whether a valve is manual or thermostatizable, just unscrew the valve knob; if it has a piston that can be pushed in, it is definitely a thermostatizable valve.
Why does the electric heater switch on and heat up before the set time?
This is a "smart" function of the electronic control, which calculates the time it will take to bring the room up to the required temperature.
The electric radiator never turns off, it always heats up, even though the time zone setting is correct. How can I intervene?
This probably happens because the nighttime temperature setting is the same as the daytime temperature setting. The night mode of our radiator should have a lower temperature than the day mode.
Why is the upper part of the electric towel rail not as hot as the remaining part?
The electric towel rail is not completely filled with liquid (diathermic), but a gap is deliberately left to allow for thermal expansion. Therefore, on some models, the top may be slightly cooler than the rest of the radiator.
Why does it take so long for the electric heater to heat up?
Because the liquid with which it is filled (Diathermic) has a higher density than water and therefore it needs more time to heat up, but at the same time it will also take much longer to cool down.
