| 1212530 | 2011-06-27 08:01:00 | Have you got the mode set to HEAT and not AUTO? Also, point the louvres downwards and don't use swing mode. | Jen (38) | ||
| 1212531 | 2011-06-27 08:05:00 | Have you got the mode set to HEAT and not AUTO Yes always on heat Also, point the louvres downwards and don't use swing mode. Read that on the web today so experimenting with that this evening thanks for the help so far - fingers crossed it'll work |

| 1212532 | 2011-06-27 08:05:00 | Yeah, so it's probably lacking an inverter to maintain a constant feed of mild warmth, so is cycling the compresser on and off, giving periods of strong heating, interspersed with periods of no heating (which feels cooler coz it's circulating those cooler layers). All normal. Simple speak being: The compressor (the outside unit) is likely not running continuously (other than perhaps a fan which might turn constantly). It's a lot like a fridge. When it detects an adequate temp has been reached it turns off the outside heat pump until the room cools down a bit). The indoor unit is really nothing more than a radiator and a fan, so once the outdoor pump stops (due to thermostat saying hot enough) the indoor radiator fairly rapidly cools and does nothing more than recirculate room air, hopefully drawing the warm layer from the ceiling down to the human level at about 1m. Once the indoor unit reports the room has cooled it tells the outdoor unit to restart the pump/compressor and start sending more warmth through the pipes again. An inverter is a bit of a gimmick, but it is a bit like a gearbox for the compressor. It allows the compressor/pump to maintain a trickle of warmth while idling. Whereas most compressors / refrigerators / heat pumps are simply cycling on and off, from full power to zero power, back to full power, consequently the in0room experience is that the warmth comes in waves, 5 minutes of warming, 5 minutes of cooling, 5 mins warming.... |

| 1212534 | 2011-06-27 08:41:00 | The backdraft is a killer on heatpumps. Floor mounted heatpumps are really bad - they create a cold draft over the entire floor of the room they are installed in. My fire is messy & requires a bit more effort, but it is a much nicer heat. |

| 1212535 | 2011-06-27 09:59:00 | Don't have the warm air blowing on you as it makes you feel colder. I have had a HP since 2004. My place was built in 1987 and is fully insulated. I think the output of my HP is about 5KW. I have the temp set at 22C and the fan mode set to auto so the fan automaticlly changes speed to suit the conditions. I only run it during the daytime evenings when someone is at home. Turn it off when going to bed, but on occasions have had it going all night if we are going to have a frost where I turn the temp down too something like 16 to 18 degress. Sounds like you have draughts in your place Globe. Haven't had it going tonight as my place is still warm from the sunny day we have had. I have big windows which catch the sun all day from sunrise to sunset. :) |

| 1212536 | 2011-06-27 10:01:00 | I have a Daikin heatpump and live in Taupo. (it gets a bit colder than Auckland) I have mine set on 20°c . It seems to keep the room nice and cosy. (modern home, open plan living, dining, kitchen 48.5 sq metres. Sometimes get too hot and turn it down or off for a while. (outdoor temp around 3°c at the moment) LL |

| 1212537 | 2011-06-27 10:10:00 | I'd suggest you direct the airflow downwards. As for what the thermo is set at - just take your time and learn what reading is just sufficient to take away that perception of the air being a bit chilly. Quite agree. |

| 1212538 | 2011-06-27 10:56:00 | we set out daikin at 24deg usually, sometimes as much as 28 LOL. get what you mean thou. it is never as warm as a bedroom with a oil fin heater. we have a floor mounted one by the wall in the middle of the room. as we got a large room with a high ceiling, 5m perhaps with one side (the longer one) top 1m full of glass. ceiling is insulated but not the lounge as that area does not permit a attic. other areas are insulated. obviously the walls are not insulated as we didn't strip the gib. |

| 1212539 | 2011-06-28 01:21:00 | We usually set ours at ~19, only really warming up, the lounge and kitchen though (parent works from home, needs the house at a certain temp as a health thing) And just close all the doors, keeps it nice a warm, walk in from down the hall (or outside) and you get a big blast of hot air when walking in.. | Empathy.
