Frequently Asked Questions
How does the 68mm depth of the Faraday Type 21 compare to standard panel radiators?
The Faraday Type 21 has a depth of 68mm which is significantly slimmer than a standard Type 22 double panel radiator (typically ~100mm) making it an excellent choice for hallways or behind doors where you need higher heat output than a single panel can provide but cannot afford the wall projection of a full double convector unit.
Does the flat front panel affect the heat output compared to a grooved radiator?
The flat front is purely aesthetic covering the standard water channels beneath while the heat output is primarily determined by the surface area of the panels and the internal convector fins so the Faraday Type 21 still delivers high efficiency heating comparable to standard grooved Type 21 radiators of the same size.
What is the correct method for calculating the pipe centres for the Faraday Type 21?
The pipe centres are calculated by taking the total nominal width of the radiator and adding the valve allowance which is typically around 80mm to 90mm in total assuming standard side connections and you must also account for the wall-to-pipe centre distance which is determined by the bracket depth.
Can I install the Faraday Type 21 radiator on a plasterboard wall?
While lighter than a Type 22 the Faraday Type 21 still holds a significant volume of water and steel weight so for plasterboard walls you must fix the brackets directly into the timber studs or use specialist heavy duty toggle anchors to ensure the fixings do not pull out under load.
Is the White RAL 9016 finish the same as standard trade radiators?
Yes RAL 9016 Traffic White is the industry standard finish for modern radiators offering a crisp clean white that is slightly brighter than the older creamier RAL 9010 ensuring it matches perfectly with modern uPVC windows and architectural trims.
Do I need to remove the top grille to clean the Faraday radiator?
Yes the Faraday Type 21 comes with a top grille and side panels for a neat finish but dust can accumulate on the internal convector fin so you should periodically remove the top grille to vacuum the dust out from between the panels to maintain maximum convection efficiency.
How does the heat output of the Type 21 model compare to the Type 22 Double Convector?
The Type 21 model generates approximately 20 to 25 percent less heat than a Type 22 model of the exact same dimensions because it lacks the second row of internal convector fins but it offers a slimmer wall profile as a trade off.
Are the valves included with the Faraday Type 21 radiator?
No radiator valves are not included with the radiator and must be purchased separately allowing you to choose between manual or thermostatic valves (TRVs) and select a style (angled, straight, or corner) that matches your specific pipework configuration.
Why is a chemical inhibitor critical for the 10 year guarantee on this mild steel radiator?
As with all mild steel products the Faraday radiator is susceptible to internal corrosion if the heating water is untreated so you must flush the system and add a high quality chemical inhibitor (like Fernox or Sentinel) to prevent rust sludge formation which protects the system and validates the manufacturer warranty.
