Hi All,

Just reading the FAQ on central heating at
http://www.cucumber.demon.co.uk/diy_test/Q2.12.html

It says "After installation and commissioning, a new central heating
system
should be balanced." And says: The "...aim of balancing is to achieve the
correct temperature drop across the boiler flow & return pipes (11°C)."

I assume that in layman's terms this means, "... so that the water that
goes
back to the boiler is cold enough to need re-heating, yet warm enough to
have delivered sufficient heat to the last radiator in the chain? Is that
right?

Sorry if this is a stupid question...

Install a micro-bore system with manifolds. They are self balancing if the
rads are sized reasonably correct. Then install an auto variable speed
Grundfos Alpha pump.

Best is a heat bank with the CH manifolds taken off the bottom of the
cylinder. The boiler will be self balancing and so will the rads. A win,
win situation all around in DHW response, commissioning and simplicity.
