Junkers WR Heater Coil Without Thread 11 Liters 87054063840
Coil – Caldeo Body – Exchanger Boiler. Not threaded
Valid for Junkers WR11 and WRD11 Heaters
Copper coil used in Junkers with 11 liters of flow. It is sent in a perfectly conditioned box so that it reaches you in perfect condition. The arms of this heater model are not threaded, they fit with a pressure O-ring and are secured with a pin.
To put a thread on it you need to buy this fitting
The heating coil must be replaced when it is damaged or broken from the inside. Sometimes, if the break is in the outer arms, it can be welded.
We recommend soldering it with copper and not with tin, due to its hardness.
A good trick to extend the life of the heat exchanger against frost is to turn off the water at the main tap at night (since this is when the temperature drops the most) and open the hot water tap to try to empty the boiler a little.
So in this way the water that remains inside and can freeze is not enough to break the Serpentin heater junkers
