Where does the heater core need to be?

The heater core needs to be right next to the fan that pushes the air through your ventilation system.

When does the water pump need to be replaced?

After the water pump is replaced, the cooling system must be bled properly to remove air pockets from the system. Air pockets can prevent the flow of coolant through the system. One of the signs of air pockets in the cooling system is when there is no heat from the vents at idle with the heater on and the engine running.

How often does a refrigerant leak cause environmental damage?

A leak of 1 kg of refrigerant causes approximately the same environmental damage as driving a van 10,000 miles. Commercial and industrial refrigeration and air conditioning systems leak too much refrigerant – leaks of up to 30% of the charge during a year are not uncommon. Leak rates do not have to be this high.

How can I tell if my radiant heat slab is leaking?

If you suspect that the tubing is already leaking (leaks may not be visible if tubing is embedded in a concrete slab) a pressure test or infra-red scanning and thermography can not only detect the leak but can detect where it is occurring. Of course if the tubing has leaked in a finished ceiling you’ll probably see water stains.

What kind of radiant heat tubing is at risk of leaking?

Early Entran™ Tubing marked Entran or Entran II is at risk of leakage and failure where it is installed, particularly if the tubing was subjected to high temperatures.
