Yey-ah! And welcome to this week's video. Today I'm going to tell you about

balancing heating systems, why you should do it,

the symptoms that mean you might have to do it, and how to do it. Firstly let's have a look at the general layout of a heating system.

We'll have a look at it schematically because that will help you understand why balancing a heating system

is so important. Let's say we have two storeys; Level 1 and gound

with the boiler at the bottom.

Coming out of the boiler we have a pump that goes up, through a diverter valve, through some radiators upstairs

and then downstairs

with common returns

going back to the boiler. OK? So you've got radiators here.

The first reason that a heating system should be balanced

is even if there's a pump on a heating system

hot water naturally likes to gravitate up

and stay upstairs and then make it's quick route back to the boiler.

So what you often find is the radiators upstairs are getting loads of heat

and the ones downstairs are still really quite cool

so what you should do is go to the lockshields on the radiators upstairs
