Electric towel rails
I noticed in Screwfix they have normal radiator towel rails used in a
CH system. But they have electric immersion insertion heaters which go in the bottom rad valve tapping to use in summer as well. I have a few questions. Do these towel rail immersion heaters have a tee piece for the rad valves? If I want the towel rail to be electric only and not connect to the CH, I assume I fill the towel rail with water. What happens if the towel rail immersion thermostat fails? Will the water boil and the rail blow up? |

I've gone off Screwfix recently, my monthly bill with them would be something like £300/mth until July, but I havent spent anything with them since. Their prices have gone up, range has gone down, and they have messed me around with their internet ordering. Toolstation are good at the moment, and for larger plumbing supplies these are good: http://www.plumbworld.co.uk/150w-dual-fuel-heating-2848-16455 Do these towel rail immersion heaters have a tee piece for the rad valves? Yes. If I want the towel rail to be electric only and not connect to the CH, I assume I fill the towel rail with water. What happens if the towel rail immersion thermostat fails? Will the water boil and the rail blow up? I wouldnt recommend that. The water will expand when hot, and it has nowhere to go, so is not a good idea IMO. There are radiators that do what you want - http://www.greenedhouse.net/dry_elec...towel_rails.ht ml I fitted one recently, and the customer was really happy with it.

Electric towel rails
With an electric-only towel rail (or certain radiators for that
matter) you fill a) with a suitable oil or b) with a 75:25 water- glycol mixture with a 10% air gap at the top. Pure water is out re freeze & corrosion (most towel rails are steel). With the water mixture, when the heater is first used you bleed off the air as it is warmed up. Alternatively, and much better from a safety perspective, fit a 3-bar safety valve which are about £8 on Ebay or £10 delivered online. Alternatively oil is perhaps the safest option (used in enough portable radiators) although I believe the EU wants / has restricted it. A towel rail element does have a thermal cutout: if you oversize the element on some you can hear one clicking on & off (an internal safety thermostat), I suspect there may also be a non-resettable thermal fuse. No idea what oil is used, I suspect a mineral oil... although could be a new market for Mobil 1 :-) |

From the trickling sound in cheap portable radiators, it sounds like mineral oil, and they seem to rust/leak a clear oil after a few years so it might well be mineral oil. Oil is pretty messy to clean up if it leaks, but so is anti-freeze (if it soaks into a wooden floor you can forget painting it pretty much for eternity because it will also stop it rotting too!). |

You generally cannot have a 13a plug in the bathroom, so the cheap plug-in timers are out, so maybe a cheap central heating timer outside the room?

I found this website as well, very helpful company with after sales.
I have learned that insert the elements on the right side of the towel radiator and screw in with the tape. And then insert the valves or blanking plugs into the bottom hole. tilt the radiator to the left 45° angle and fill the radiator with 75% water 25% antifreeze mixture. I will recommend to install three bar safe valve on one of the top holes. Make sure you not operate the elements before fill the radiator completely link: www.towel-radiator.com enjoy warm dry towel :)) |
