FAQ - Vehtec

Where should the pump be placed in the Veheat system and is a pump needed?

The pump should be placed in the end of the system closest to the return side to the engine. The engine and preheaters (if any) have pumps as well, and will limit the flow if placed one after the other.

Which type of valve should be mounted and how?

A 4-way non-return valve can be used in combination with a 2-way valve, but it is possible to use a 3-way valve instead of both – when the 3-way valve is normally closed there is flow in a closed loop back to the engine through the defroster and preheater (if there is one). When the valve opens it takes a circuit through the heating system, ensuring that in both cases there is coolant flow to and from the engine.

How should the convectors be mounted on the walls?

The convectors should have 60mm distance from the floor, to ensure that there is colder air being drawn up through the cooling fins. It is also strongly recommended to have approx. 40mm space above the convectors for proper airflow. If there is 60mm distance between convectors and floor, it is easy to mount our VeForce fans to give a strong boost to your heating system! It is recommended to have approx. 300-500mm spacing between the mounting brackets.

I have mounted an Eldi heater and I have no circulation, or the overheat protection turns off the heat?

To prevent dryout upon the first start, fill the heater with the glycol-water mixture before the hoses are connected. Before connecting to the water system, check the direction of flow so that it is connected correctly connect the heater, with the outlet in the center (see arrow and red ring on the heater). The inlet is the pipe to the side, marked with a blue ring. Bleed the heater before it is connected to the system. If there’s air in the system, airbubbles will occur, and the circulation will be bad and the heater can be over heated.
