Convector vs Column radiators

mashed13

Looking at getting few new rads around the house as some are really old

Just as an example ''Kudox double panel, double convector'' 600x600 - 50e then there is something like Acova 2-3 and 4 column starting at around 150e

Is there much difference between the two to justify 3x price increase?

Apart that they do look really nice! :rolleyes:

Don't look at price or size first.
What you need to do is work out the heat requirements for the space (room) you want to heat. Then you look for a radiator to match that requirement. The cost is the final parr as you compare different styles and manufacturers.

wouldn't really know how to calculate the heating requirements, if anybody wished to share any info on this would appreciate it.

On the other hand I'd say there should be more aspects than only the actual heating requirements. I should consider too, how long will they last, how long they stay warm etc

Thanks

prices and sizing were mainly for example purposes

get smart rads, the cost of electric heating is ridiculous, Id wanting something with a thermostat, timer and app for it...

I sure must look into them

Central system is heated with the mix of oil and range, I'd stay away from electric rads :eek:

You could use one of the many online radiator calculators, e.g.

Radiator Calculator

They may last decades, they may only last a few years, the deciding factor usually being how well it has been installed, how clean the central heating system is, how well it is maintained.
Heat loss will depend on various factors, sizing of the radiator compared to heat requirements and temperature of the room when the heating is switched off.

Got playing with the website, its good, gives plenty of useful info, thanks

Current rads don't hold heat at all once the heating is off they cool off within minutes. I would love something that'd stay warm at least for another half n hour to an hour after heating is switched off....

There is no benefit in having rads that hold heat longer after you switch them off.

You can get such radiators certainly, basically heavier ones with more steel in them typically. But they take much longer to heat up from cold than the type you have at the moment. There is absolutely no saving to be made, and it will take longer for them to get the house warm.

This.

Every stick has two ends. It will be not cheaper at all if your rads stay warm longer after you switch heating off. You will only lose more control over them. Will you get more water out of bigger bucket? Yes if you put more in it first.

Also you should aim to have constant comfortable temperature in your house. If you fluctuate it too much the comfort will be very poor and you run into increased risk of mould. Cold objects submerged in warm air generate condensation on the cold side.
