| 882290 | 2010-05-05 06:22:00 | Just had a look at ours -- theres an on/off button in the middle. They use bugger all power, we have had ours for a couple of years now and never really noticed a difference in the power bill when its going or not. SWMBO using the clothes dryer when its wet and cant hang out the washing will use more power. |

| 882291 | 2010-05-05 07:06:00 | so if theres smoke/fire in the fan, or need to do maintenance/repairs, how do you turn it off ???? there must be a way of switching it off for safety reasons, if not kick the installer up the ****. It is possible to turn it off at the control panel, as Greven has found, however this is just a temporary measure and the system will kick in again in about 8 hours (IIRC). I've never heard of the fan burning out - I've had the HRV in for several years now. Maintenance is the responsibility of the installer - they come round even couple of years (or should) to replace the filter and check the unit out. As wainuitech says - they use bugger all power, so there's no point in turning it off. You can get better savings by turning down your hot water cylinder thermostat and having shorter showers (sending your daughter to university in a different city will achieve the similar, or better, savings! :D) |

| 882292 | 2010-05-05 07:13:00 | While I was living alone, power bills were constantly $90 - $100 summer or winter & it was the same in summer with flatmates, but my last power bill was $170. Hot water has jumped up, but I was expecting that. What I wasn't expecting was the general power use to almost double. We don't have any electric heaters - just a Yunca fire & heaps of firewood I got free from a burnt down house. |

And was the last power bill estimated? The seasonal factors that the power companies use for estimating usage usually kick in around about this time of the year - or did when I worked for one some time ago... Also check that your hot water cylinder isn't constantly or regularly overflowing on the roof - this will pump up your power and water bill, since you'll be paying for heating water that never makes it out a tap or showerhead (how's your water usage?) |

| 882295 | 2010-05-05 09:47:00 | You can still ask for the separate meter even if you don't have it wired. But OP has electric water so you can sure do it. We have gas instant water and we got composite installed at a price of $50 by Genesis, they also installed the newer smart meters that does not use estimate anymore nor meter readers, they have a GRPS I think that sends it to head office. I did some analysis what I found out, the items running 24/7 eat a lot. A fridge/freezer takes $15 per month. A chest freezer takes $8. Any computers and many running 24/7? You can get $20 power meters from DSE that measures how much power a device is using, you plug it between the wall and the device. What you could do is get up early one morning and take a meter reading and revisit after 15 or 30mins by turning nothing on, just using the bare essentials. Convert this figure to a 24hr daily and then times 30 days a month, that would your bare essentials baseline. |

| 882296 | 2010-05-05 09:52:00 | You can also take various meter readings, ie., for a 24hr cycle. After getting up, after AM session, after lunch session, until dinner time, after dinner time, until bed time and again the same time in the next morning. You then get to know when you are consuming the most. For us we easily use approx 50% of all consumption between after dinner time and bed time. |

They are GSM and have a SIM card and modem installed on the meter - on the Vodafone network, I believe. No doubt that pumps their market share figure up a bit!! |

| 882298 | 2010-05-05 10:19:00 | One care I would say is, some people on the net argued that their old meter was inaccurately slower, so they consumed more power but paid less. I did a comparison with my old and new meter, for us it was the same. | Nomad (952) | ||
