I have a older house that has the boiler in the celler and baseboard
radiators in every room.
three years ago I purchased and installed myself a new boiler. the way
the older system was installed was a large loop starting in bedroom
then going complete around the house back into the boiler..the house is
always heating unevenly. hot in the first room..and getting cooler as
it loops. I'm thinking about redoing the hole system but I'm not sure
I have it correct. my Idea is to start a 1 inch copper pipe down in
the basement and at every room put a 'diverter valve' ?? with 3/4
copper up to the baseboard then back down to the main pipe. do this for
every room with a baseboard. is this the way it should be done? do you
think it would help with the uneven heating. any other ideas ?

thank you

It might help but I would start with making sure there is no air in the
system. Once the pump circulates the water one time all of the
baseboards should be about the same temperature. It is amazing how
much a tiny bit of air in the system will affect the performance. It
you do want to install a 1" manifold with 3/4 take off pipes you need
to install directional or monflow tees to make sure the water is
flowing to each loop. If you don't install these tees the flow will
take the easiest path and may make your problem worse. The type of tee
I'm talking about can be seen he

If you had even heat before it is almost certainly air in the system or
a bad pump.

You could also add additional zones with thermostats and solenoids but
that is not going to give you a great improvement in a one-story home.
