XEFRO Electric Heaters - Tech Data Required

[Bessie]

I have just visited the home of an elderly couple who have Xefro 'Graphene' panel heaters fitted throughout the house - I was told that they stopped working shortly after they were installed (over a year ago). To cut a long story short, the original sales team made off with the £4k up-front deposit and were never seen again however the second set of installers made a neat enough job - only problem is they left without providing any sort of user manual or the promised controller 'app' for phone/tablet. The system comprises about a dozen radiators grouped into 4 zones. Each radiator has its own wireless receiver, and each zone has a battery-operated wireless controller. There is also a single black box (labelled 'do not unplug') plugged into a 13A socket which I would guess connects to the house wifi system to allow remote control. Anyhow I managed to get the heaters working again by fitting new batteries to the zone controllers, switching on the 'black box' controller then rebooting the receiver controls for each heater by just switching off for 30 secs then back on. What I can't seem to do is to control the zone temperatures - the controllers have up/down buttons but they don't seem to do anything other than display ambient temperature. Has anybody come across these heaters and, if so, do you know where I can download a copy of the user instructions or any other technical data? Many thanks.

Apart from instructions, any installation certificates issued? silly question really I suppose. What was the name of the company that did the install? Roy Rogers and Trigger?

try here:

A U.K. startup wants to use graphene to heat your home - http://www.digitaltrends.com/home/xefro-uses-graphene-to-heat-your-home/

the actual xefro site is forbidden. maybe access is only for installation companies or distributors.

Yeeha! I believe it was the manufacturer (Xefro) themselves who made good after their sister company (Complete Energy Europe) defaulted on the original sale. But I don't think either company exists any more. The internet forums are awash with customer complaints. My friends have no documentation other than a glossy sales brochure.

A quick Google search reveals that a company called 'complete energy Europe ltd' have scammed a number of people with these xefro heaters, I can't see if they are related to xefro or not.

I also read somewhere that the electronic controls were supplied by European Circuits Limited, which seems like a respectable company - I have emailed them to see if they can help.

Blimey - a £4k DEPOSIT? What was the total amount to be paid? Seems like a lot of money for what seems like fairly basic electronics. That twin 13A mains socket is interesting with the 4 fixing screws. What make is it?

old MK and crabtree socketrs had 4 fixing pins, back in 60's/70's.

it's a bugger when you have to change them. needs to be a new k/o box as well.

You want to see the rest of the house! Its a bungalow (a large bungalow admittedly) with a 3-phase supply. No consumer unit. Industrial grade cast iron 60A switch fuses for some of the circuits. Not an RCD in sight except for the new heater circuit.
