Installing an extra radiator Help and information on all topics relating to your central heating, air conditioning and ventilation issues.

I want to install an extra radiator. Pipes are 15mm. How can I determine which of the two pipes I want to use is the 'out flow pipe' and which is the 'return flow pipe? Does it matter which way the water flows through the radiator? The radiator has no thermostat.

It doesn't matter which way round. If you want to fit a thermostatic rad valve buy one the reverse flow.
