Plumber to sort district heating


Recommended Posts

That's not necessarily due to problems with the district heating installation.


Was it an all new installation, or a repacement for an old oil boiler?


A radiator that is cold at the bottom and hot at the top after being 'on' for a reasonable period is usually sludged up. But obviosly that would not apply to a wholly new system.

U possibly have air in the system!


Go around each heater and either on the left or right hand side at the top you will find a small valve with a hole in it. You need a square key(purchase from Hays if need be) turn this anticlockwise until you hear the air being released. Make sure you have a towel handy. Keep the valve open until water starts to appear then shut the valve.


Repeat for each heater.


Then go back to you're district heating unit and fill the tank until it reaches a pressure of 1.5 psi. The valve showing you this is top left of the unit.


To do this look under the unit. There should be a hose, usually flexible going between 2 pipes. open both valves and keep any eye on the pressure indicator until it rises to 1.5.


Pretty straightforward to do. U should try this before calling a plumber.


That should solve the cold spots, not sure why ure valves are not open enuff. I don't understand what you're saying. Hope that maybe helps.
