Central Heating
What is involved in replacing the element on a dual fuel radiator, fed by an HIU
Anonymous user 9 March 2024 - 3.31 PM
We have two dual fuel radiators in our bathrooms. Both work fine when the heating is on. However one of them doesn't heat up when turned on at the plug. The switch appears to be fine - the LED on the switch itself lights up, and also there is an LED on the valve that lights up when the switch is turned on. side note - the LED on the non-functioning radiator is a different colour (RED) to the one that works (BLUE). I have no idea if this some sort of error indicator or just a different colour LED though. I contacted towelrads directly and they were of limited help, but their response seemed to suggest that there are different coloured LEDs on the valves. I've been told the valves installed are "Towelrads Smart Non-Thermostatic Elements Radiator Valve for Electric Towel Rails 300W - Chrome - 126001" So I'm working on the assumption at the moment that it's probably the element that's blown. What I have no idea about is what is involved in replacing it. Can it be replaced whilst the radiator is mounted in it's current location? i.e. by isolating the radiator somehow and then draining it. Or does the radiator need to be taken of the wall? If the latter then how complicated is this given the heating system is operated by an HIU (rather than a "normal" heating system like a gravity fed tank or a pressurised combi boiler). Does the fact the HIU is in turn fed by a shared heating system for the development matter? (it's a dedicated HIU inside our flat - this should mean it can be isolated, right?) And is this a job for a plumber or an electrician? Obviously it's not something I'm going to attempt myself - just want to know what I need to prepare myself for!
