Tried everything that I can think of.
If I turn off all the rads and then turn one of the upstairs rads on
it will heat up OK but if I try to increase the number turned on the
the heat is greatly reduced and infact only a few rads get the heat at
all, I know it at first seems like a balancing job, but surely an
Ideal mexico super 3 60000btu boile can deal with a few rads
upstairs..

I live in a 1965 4 bed detached house with 4 doownstairs rads and 6
upstairs rads. open system CH. Measuring the pipe temps on the
furthest rad ( single) when turned on by itself gave a reading of
inflow=125F , out flow=101Fr both valves set fully opened.

Is it possible to add a 2nd pump to the system to boost the water
circulation speed is necessary..

You need to FIND the pump.

OK... I'll dedicate this weekend to the search..

Can you help me to narrow down the search.. The boiler is floor
standing on the ground floor in the kitchen. The hot water cylinder is
directly above on the first floor..

Is it likely that the pump will be VERY close to the boiler , is there
any hints that may help me track it down without ripping up the entire
kitchen floor, If when I find it I shall probably want to resite it to
a more convienint location, can this be next to the hot water cylinder
upstairs or does it have to be really close to the boiler.

Sorry to be a pain but I'm a little wet behind the ears on this one..

Identify every pipe in the house especially the heating ones and trace
their routes. Making educated guess where you can't see. Istrongly suspect
you have gravity HW and pumped CH. The pump must be on one of the pipes
fairly near the boiler before it splits into various part of the house.

Ditto with any flexes or cables attached to boilers, thermostats or time
switches.

Identify any 'boxwork' that might at first look 'structural' but is
actually hiding the pump.

Trace the route of every pipe that leaves the boiler.
