| 865226 | 2010-03-09 04:01:00 | Hi, we had a visit for an assessment. Rather than take his salesman talk. Anyone got one installed? Does it save much power bills? Does it become more warmer, how has winter been? How much heating do you still require? Cheers. |

| 865227 | 2010-03-09 04:07:00 | In winter the air in the roof space is colder, in summer its hotter, Why would you want to be colder in the winter and hotter in the summer? And what madness tells a person that the air in their roof space is healthier then the air in their house? If you believe the air in your house is unhealthy then you have bigger problems then what an HRV can fix. If you have a problem with poor circulation on your house then try an extractor fan. |

| 865229 | 2010-03-09 04:24:00 | Note taken . Thanks . He said that research says you save 60% in power bills by redistributing the heat . He also said that in winter there is still warm air up in the roof space . We have some mould at the rear bedroom - what solution is available? |

| 865232 | 2010-03-09 06:25:00 | If you want to go down that road you might want look at some sort of heat exchanger system. We have Moisture Master with a inline heater. This does take the chill of the air in the morning.I don't think its worth what we payed for it. On the plus side my little girl hardly uses her pumps now and the house is a lot dryer to.Still have to use the fire in winter. Have a look at some these sites (www.google.co.nz). |

| 865233 | 2010-03-09 06:29:00 | We have ours installed for just on two years now . A lot has to do with the type of roof you have as well . A a tiled roof retains the heat better than a metal one, but of course takes longer to heat up . When we got ours it was the start of a winter, out side was about 6 degrees - in the roof, ours was approx 17, the house was the same . I went to a customers house just down the road, they have a metal roof, theirs was 27ish ( yes 10 higher) while inside they had the temp set to 20 - its was nice and warm, and NO fire or other heating . Ours at the moment - See for your self ( . imagef1 . net . nz/files/P1000994_ . JPG" target="_blank">www . imagef1 . net . nz) - the inside of the house is at 24, outside its about (guessing 12 - 14) during the night the lowest it drops to is 11-13 in the house . In fact quite often we have to switch it to cooling mode just to cool the place down . The HRV 's push out the damp, so the place feels warmer anyway . The secret is to have enough outlets in enough rooms, and a big enough unit to handle it . As for cost -- never noticed the power usage increase . |

| 865234 | 2010-03-09 07:03:00 | My brothers house in Tauranga has one and it works great. Went there at christmas time and the cool air coming through the vent at nighttime was wonderful. No need to have a window open. As wainui said you have differant modes a cooling mode for summer and a heating mode for winter. They also have a filter in them and a fan to push the air out. I would ignore the posts before rebels. :) |

| 865235 | 2010-03-09 07:13:00 | There is a difference between a system that just pushes air around and one with a heating unit. I'll let everyone work it out for themselves but here's a hint...ones a heater. And HRV have had at least one complaint upheld due to their claims. If you do have a situation where your house is substantially colder then your roof space in the middle of winter then I would strongly suggest having another look at your ceiling insulation as that heat isn't coming from outside the house. |
