| 1208761 | 2011-06-13 02:29:00 | The controller for my newly installed underfloor heating doesn't display a temperature - it runs in a range from 1.0 - 10.0, with one basically being a frost-protection setting. If the matting in the dimensions I had installed is quoted as drawing 350w: - Is the 350w at full load (i.e. 10.0) - Does that scale pretty much exactly? (i.e. 1.0 = 35w, 5.5 = 175w) Just curious really. . :D |

| 1208762 | 2011-06-13 02:47:00 | I presume the controller has a smooth range from 1 to 10 rather than click-stops . If so, it's either thermostatic or electronic duty-cycle . If it's a thermostat, the power will be full-on until the temperature sensor says it's hot enough . You could have it set to '1' but if it's a very cold environment it might never reach the temperature represented by 1 . So it will be on full power all the time . Even at '1' . If the controller is of the duty-cycle variety, it will act like the simmerstat on a stove . In which case it will use about half the power at half the setting, etc |

| 1208765 | 2011-06-13 05:11:00 | Why not ask the manufacturer/supplier/installer ? Then you will get a real answer, otherwise it can only be guesswork. | Terry Porritt (14) | ||
| 1208766 | 2011-06-13 09:11:00 | I must say that 350W doesn't sound like much heating capacity, though I suppose if it is left on 24-7 it would warm things up a bit . IIRC, the last time I tested one of those it consumed a great deal more than 350W . Cheers Billy 8-{) |
