Which radiator has the highest output?
You can tell by looking at the radiator.
You need to consult the manufacturer's technical data.
All radiators have the same output.
The size of the radiator determines its output.
What does a Magnaclean do?
Collects iron oxide.
Filters water impurities.
Regulates water temperature.
Increases water pressure.
This component is called
3 port actuator valve
2 port actuator valve
4 port actuator valve
Single port valve
What is the purpose of a Thermostatic valve on a radiator?
To increase the temperature of the radiator regardless of room temperature.
To turn off the radiator when the air temperature in the room is at the required level according to the setting on the valve head.
To control the flow of water through the radiator at all times.
To provide a manual override for the heating system.
Why are inhibitors added to a heating system?
To prevent iron oxide build ups
To prevent the water from freezing
To reduce noise in the system
To improve energy efficiency
