change antifreezer heater

[samsom]

Hi all,
Does anybody know how to change heating element in the evaporator – 4R1. Which is for climaveneta focs/b 4822. Good money. There is some trouble for changing, I have no idea how to do it.
Any help would be very appreciated. Photo in my avatar.
Kind regards,

Pull it out !!
Spray some WD-40 around it leave it for a few minutes then just slide it out and slide the new one in.
DON'T wriggle it ! Just pull it straight out
Cheers

I have no idea !
I never had one snap off.
Order a new end plate gasket and remove the end plate ?

another question, which needs this option? if the incoming water is above+ 11*C, and in winter all the water is drained. if do you have, could you pls send me sectional drawing of evaporator.

The evaporator is just standard shell and tube configuration.
I dont have a diagram for it.
Its make up depends on the number of circuits connected.
The heater is a standard rod element.
If you were to remove the evaporator end plate you would probably find the element will come with it.
But going by your information you would probably never need it.
