New radiator pipework.

[givemestrength]

I have a new radiator to put into a room where there is not one previously. The radiator is near the boiler (about 2 meters) Am i right in thinking for an openvented system that i cannot connect to the pipes near the boiler because of reverse circulation?

I assume that i have to connect after the zone valve?

If this is so i would also asume that the best way to achieve what i want would be to cut into the pipework in the room above and bring down the wall to where the new rad will sit.

Please can someone advise if my logic is correct. Also just out of interest does this still apply if you have a combi?

As long as it is after the valve.

Correct

Combi does has valve in the boiler

Cheers for response.

Your last point about a combi. From what you have said i can connect a new rad anywhere on the flow and return no matter how close to the boiler as the valve to switch between hot water and central heating is within the combi and not a 2/3 port valve. Have i understood you correct?

 

[kevplumb]

yup you have it

 

[bengasman]

Why were you asking about the zone valve if you don't have one?

 

[givemestrength]

Cheers fellas.

 

[givemestrength]

was thinking of putting a combi in sometime in the future and i like to understand how the systems work. There is a valve in there at the moment.

 

[bengasman]

In that case, you would still have to branch off after the valve.

 

[givemestrength]

please clarify. I thought a combi had the valve within the boiler and cylinder/external pump and 2/3port valve would be gone

 

[kevplumb]

you are correct

i think ben meant if you left the valve in you can cannect a cylinder to a combi as well

 

[bengasman]

True as that may be Kev, what I meant was that as long as the valve is in use, you will have to tee off for the rads after it.
