New radiators more efficient?

    Hi thinking of upgrading my radiators but not sure it's worthwhile. Doing a bit of research it states newer rads put out more heat and use less water. My rads are about 20 years old. Screwfix seem to have decent deal which includes trv for free with each rad bought.

    It will still cost you more or less the same to heat the rooms to the same temperature as they are now.

    There will be some savings if you keep the new ones the same size as the current ones. This saving will come from you being able to run them at a slightly lower temperature, allowing your condensing (I'm assuming condensing) boiler to remain in condensing mode for longer. Assuming your condensing boiler is already running in condensing mode for some of the time already, the savings aren't going to be huge.

    No. It won’t be any more efficient. If you got aluminum radiators they would heat up and cool quicker but they wouldn’t be more efficient. You could get a more compact radiator maybe but I don’t think the one you linked to is going to be more compact or give more output. Maybe a bit but not much.

    is there anything actually wrong with your old radiators?

    Thanks for swift replied lads. No current rads are heating perfectly, have condensing boiler and back boiler on stove. Just thought it might be less water for back boiler to heat. Won't bother changing so. Thanks again

    If you wanted to make a change and fancy a project you could fit TRV valves, maybe automated and fit a new controller.

    Considering both are the same size there will be nothing to gain.

    Both are double steel panel rads with fins inside.

    A wise man once said 'If it ain't broke don't fix it' 20 years in not 'old' in radiator terms, chances are if you fit new ones the pay back time will be at least 20 years depending on their efficiency. Gunk may have built up in your heating system over the years, a good flushing of the system (professionally done) may be a better investment.
