Balancing a centrall heating system

[BigHammo]

I have had 2 new radiators in my new extension which don't warm at all. I have been told to balance my system. Do I need a thermometer to do this is there another trick of the trade to use.

My plumber mate says I need to put bigger pipes in my feed from the header tank, but I don't understand why and he is crap at explaining things. Can you do better?

Yor plumber mate is not only useless at explaining things he sounds like a useless plumber

More info would be good too Have the 2 new rads been connected to the same pipe, What size pipe have been connected ?

As for bigger pipe from the header tank tell your plumber mate to start up ballet dancing classes

 

[BigHammo]

The rads were run from the nearest rad, one in the new conservatory one in the kitchen. Same pipe sizes 15mm. My mate is bit of a dreamer, but I may have misheard him as he says my CH system is really weird. e.g, when I changed the speed of my pump it sucks air out of the overflow and a get masses of in my rads.

Turn the ones off that are working and see what happens to the new ones

 

[BigHammo]

i turned off the next radiator, nothing happened, I turned of the next one in the chain and the radiator got slightly hot at the top only, I haven't turned any more off. Whats next?

 

[Diyisfun]

You were told TURN THE ONES'S OFF THAT ARE WORKING. The idea is to see if the new ones get hot.

Get that tutu out pas de deux, anyone en point..........mmm nice codpiece

 

[BigHammo]

Sorry, the one that wasn't working, got hot only at the top. The other one, that wasn't working, did not get hot at all. What does this mea?

Only decent plumbers to answer please.

 

[sime10]

Can I answer or am I not a decent plumber?

If all the other rads have been turned off & this is what is happening on the new, then I would suspect a blockage or air. (But Im not a plumber)

First of all it's not a plumber you need to speak to. You should be speaking to a heating engineer. It sounds like you have branched off the flow and return from another radiator and you're not getting the flow to your new radiator. You may want to consider taking the flow and return from your main carcass. Simple fluid flow dynamics.

 

[BigHammo]

Thanks DIYISFUN and Tennooge. What do you mean by main carcass? Is this like a manifold or something? Can you just not chain rads together or connect them in parallel. Excuse me if I am not up with the terminology.

try tracing the pipes back to a 22mm flow and return and branch from there to your new rads
