    Should I go for heat management or heat retention when choosing a radiator and which are best?

    What do you mean by heat management? What do you mean by 'radiator'? How do you intend to use this 'radiator'?

    I was told that heat retention is best. But to make it more to the point, I am going for column radiators as it is a good choice for spacious rooms. Someone mentioned panel ones, but I spoke to a few tradespeople and was told they are not suitable for the house. Rooms have double glazing and one has patio doors. Keen to know what steered choice of radiators from folks. For example, one pro suggested aluminium radiators but I am new to this.

    How would a column rad (as I understand it) be "a good choice for spacious rooms"? Injecting more heat higher up in the room above where the people will get the benefit feels strange. (And no one I know with a hydronic tall rad is happy with their choice.)

    Don't forget that whilst a heat retention rad would 'retain heat' to give it out later the heat will come from the radiator some time after it is switched on. If the rad stores heat for later then this can only come from energy that is not put into the room at switch on.
    You need to decide what you need - instant heat or some stored heat for later. With electric heating there are no free lunches, spend 1kWk of electricity and you get 1kWh of heat to use now or use later

    Yes, stored heat for later and I was asked about that by a guy on a Q&A page on my job quote where I asked the same questions. Probably going with horizontal radiators for some rooms, like the bathroom, vertical one near the patio doors.

    In my opinion there is no point storing heat unless you can store it long enough to benefit from lower tarriffs eg E7 or similar.

    Any other forms of storage will just lead to temperature under/over shoots. Eg Stat calls for heat but rad can't deliver it until it's filled up its store. Later stat turns off but rad keeps pouring it out.

    Only water filled thermal stores and some electric "night" storage heaters are able to control their output.
