Well, this is interesting reading.
Recently, I attended a house where this heater swap had been done. The company that came only changed the heaters. They told the homeowners to have their E7 tariff changed.
This was done, but the meter guys didn't reconnect the E7 board... leaving my customers without any heating. (said they weren't allowed to).
I was actually thinking of doing this myself as a business idea, but you guys are putting me right off!
Have the customer get an isolator installed from their supplier to make the changeover easier, swap the heaters, test the circuits and move the E7 board to 24hr.
Hence a recent thread I made about disposing of the bricks.
My heater choice would be the Rointe Kyros range, but would accept other suggestions.
Reading the Rointe website, it does say that any warranty would be void if the plugs were cut off... so i'd have to change the switches to sockets, and therefore changing the board to RCD protected if required.
I don't know, but i'd expect other manufacturers to say the same regarding plugs??
