How to connect a heating element to an aluminum radiator [Instruction]

In addition to the heating radiator itself, a heating element is needed. We will use a 700 W heating element - this is more than enough to heat up a 10-section aluminum battery.

You will also need a pressure gauge to monitor the pressure in the batteries. Water will be used, and as you know, it tends to expand when heated. Although the radiator is designed for use in systems up to 6 atmospheres, we decided to be safe.

In addition to the above, you will need a standard set of plumbing:

For a better connection of the heating element to the mains, we will use a soldering iron.

We unpack the radiator battery. We examine it for defects, also look inside, and check the absence of foreign objects in the collectors - this can also happen.

To mount the heating element, apart from the silicone sealing gasket, nothing else is needed, so we remove the thermal relay from the electrical appliance and install it in the lower radiator manifold.

Now you need to connect the thermostat. To do this, we prepare a wire with a cross section of 1.5 mm².

We clean the ends and use a soldering iron to tin them. It is not necessary to solder the wires.

We connect the wire to the thermostat, tighten the terminals with a screwdriver.

We install the relay back on the heating element.

Before pouring water into the radiator, it must be prepared for this.

Plug the lower manifold with an inch nut, which is located opposite the connection point of the heating element, install the Mayevsky tap (nut) to drain the water and install a pressure gauge. The latter is not required to be installed.

Pour water into the radiator. The volume of radiators may vary, in this case 0.28 liters per section. You do not need to fill it completely - since the battery does not have an expansion tank, you need to leave room for the expansion of the coolant.

If you make a mistake, then it’s not scary, you can bleed off excess pressure through Mayevsky’s nut. To determine the pressure, we decided to equip the radiator with a pressure gauge.
