Radiators recommendation

[johnny2007]

oh glad you cleared that up that you dont understand how a trv works on various sized rads in reply to my question .
And 95 % of pro`s do not fit rads to the size rad calcs come up with otherwise there would be a lot of disappointed customers out there.
You might have learnt that if you had attended an extra week after your 6 week course

So what size do you fit compared to the result of btu calculators?

The BTU calculators are reliable but you need to be careful with specific details that can effect the feel of the heat emitted or the room itself, or personal preference.

Also most radiator manufacturers list the outputs on a ridiculous flow temp like DT 50 to make the rads look like they output more than what is sensible - so take into account and size according to the adjustment factor and actual flow temperature.

Morning everyone, slow progress on these radiators due to other projects.
My wife aka the boss, has said that Stelrad radiators are too expensive and found very similar ones with good reviews called NRG.
They seem to have a very nice BTU output.
Anyone have tried them?
Thanks

the radiators they sell in wickes are actual stelrads and far cheaper then badged stelrads

Really???
I'll have a look.
Thanks!

As a general point, I think it's not a bad thing to have plenty of rad area, and choose rads with a high kW/m2 output (at a given DT) and they do vary. That way you save gas by getting maximum condensation, and if in future you convert to a heat pump, which needs lower water temperature for good efficiency, may not need to change the rads.
This was discussed in a thread a while ago, but I can't find it just now.

Also a lot of independent merchants sell Henrads
Identical to Stelrads made at same plant at Swinton.
Also better price.

Found that thread.

Might be worth asking Alan 483256 what rads he bought.
