Plumbers question - radiator efficiency

[ColinW]

Scenario - New 2 storey house ; oil heated : radiators in every room fitted with thermostats, oil burner situated approx 5 mtrs from house.

Problem - last three radiatos on circuit upstairs remain almost stone cold while heating is on everywhere else .

Suggested solution by my plumber - Close valve on downstairs radiator circuit to get full use of upstairs circuit and alternate between circuits as needed.

I suspect my plumber is taking the **** but I know almost nothing about plumbing and therefore cannot argue the point with him at present. Some plumbers wisdom would come in very handy here .

Thanks in advance

Have we been here before? See this on how to balance the radiator system.

It is also possible that the boiler isn't up to the job but unlikely given that this is a new installation (mind you I've always found that it is better to assume nothing when it comes to these things).

The system should work perfectly with controllable heat at any point. Anything else is codswallop. Get the man to commission it properly.

Cheers mate ,

Thats exactly the info I needed! Just one final quick question though... is it absolutely correct to state that each subsequent radiator on a circuit requires ascending levels of pressure to be balanced correctly and therefore function correctly??

No. The rads are all in parallel so they should all get about the sam epressure. If 3 are cold it s more likely to be an airr lock - try shutting all the rest just to push it out. TRV's sort thamselves out as long as things are roughly babalnced. Some may get hot quicker but they should all end up ok. Is the pump on max speed (3) ? It may not need to stay there but its worth a look The boiler should be big enough to heat all the rads together.
