Radiator piping and valves

[wasabishot]

Hey Guys!

I entered this house where installed a central heating system, which consist of 8 radiators heated by a wood stove.

the radiators have a twin entry without valves on the right side, on the bottom.
on the upper right there is a trv which i guess stop the circulation after entering the radiator.
I am going to remake all the piping with plastic due to licking in the old copper one under the floor.

my questions:

1) does it actually matter which pipe (flow/return) goes on each of the entries in the twin connection.
2) becuase the feed is so close to the floor i have no much space to fit the lockshield valve. does it matter the direction of the valve (horizontal/vertical)?
3) does anybody knows a good way to cap one of those entries? this way i could use the left nottom side drain which is unused for the return pipe and lockshield valve.

thanks in advance for any kind of help

If it's a wood stove then you ain't using plastic.

I saw this setting in my neighbor's home.
the pipes close to the stove are all metal.
downstream it becomes ppr which flows to the radiators.

have you been to college, done an apprenticeship or trained anywhere, just curious

I agree. A wood stove is an uncontrolled heat source. You'll create more problems than a few leaks by running plastic pipework.

And in answer to your question regarding piping the rads. Yes, it is extremely important you get the flows and returns the right way round!

thought so, check your insurance is in date

So we know how to answer you correctly.

Just because your neighbour has plastic pipe doesn't mean it's right nor does it mean they have the same setup as you.

I once saw a drunk bloke trying to shag a tree, just cos I saw it doesn't make it right.

TRV's as well. Hell no.

come on.
I came here to get a real advice from the pros.
It is because i have the respect to those who deal with it on a daily basis.

it isn't the first time i pipe the radiators. but it is the first time i see this twin entry at the bottom.
is there anyone who will take my questions seriuosly here?

 

[lame plumber]

trouble is a little knowledge is dangerous and any advice based on limited knowledge of the setup could ruin someones day.

Seriously, leave it alone and recognise your limitations.
