865267	2010-03-10 06:26:00	Why is it that the people who don't have these products whether HRV or Heatpumps etc degrade them without trying them out. Because its merely a fan, a very expensive fan. Besides which the claims don't make any sense. I would have to acknowledge that in some bizarre cases people are getting some of the claimed benefits but she stinks of snake-oil to me.	Metla (12)

LL :illogical it must be set up wrong, or your location in the part of the country and roof is hotter. It needs adjusting - thats all. you can turn them off you know - if its pumping hot air in at night, then adjust the temp on the scale so its higher than the roof, or as high as it will go and it wont pump. This here (www.imagef1.net.nz) was taken at about 11pm last night - it was 10 degrees out side, so the roof is cooling down, and notice its on cooling mode,its set to 22, but still has1 degree to go - if I lowered the temp down to 18, it would keep cooling till it got to that 18 as long as the roof temp was 18 or below. Once they get to the set temp, they turn themselves off. As for heating during the winter -- The car port is half full - just one more load to come, then stack it away :D	wainuitech (129)

Still think it is a mistake that her landlord didn't put in a heatpump as we all suggested! Oh well, she may not be there much longer as she has had an offer of somewhere a lot cheaper.

I went along to Bunnings and got the cheapest system they had, it pumped ceiling air in the lounge via a 38watt fan to two rooms at the far end of the house using cheap insulated piping. After the fire is started and the fan started the other end of the house gradually warms up and heat is pushed back to the lounge through the rest of the house making the whole house cosy.( just as well, as the room with the computer is no longer brass monkey country for internet sessions in winter). All I have to do now is get an electrician in to install a switch, rather than using an extension cord through the ceiling access. We do have very good insulation though, so I guess that keeps the heat from escaping too.	PPp (9511)

We do have very good insulation though, so I guess that keeps the heat from escaping too. That's the sort of system I put in, a 'Weiss' from Mitre10 a few years ago, and there is a thermostat for setting when it switches on and off. It works really well during the winter distributing warm air around the house from the lounge, and keeps my computer/electronics room, which has a south wall, quite warm.	Terry Porritt (14)

LL It would definitely not be setup right, as it does have a thermostat in it, that should turn it off in that situation.	robbyp (2751)

Nothing wrong with log burners, and if you are using your own wood, it would be considered by many as 'green' heating.	robbyp (2751)

I don't have a HRV system but know 2 people who have and are very happy with it. I do have a Heatpump and are very happy with it but could do with a bigger unit. I know at least 6 people with Heatpumps and are very happy with them also. :) You do notice more from getting a heat pump, because it actually heats and cools the house, and is a heater replacement. A DVS or HRV is a ventilation product, and not designed to be a heater or cooler, they are mainly designed to get rid of condensation, and are a dehumidifier replacement, not a replacement for a heat pump. The fact that it may heat or cool in certain situations, is just a bonus.	robbyp (2751)

The fact that it may heat or cool in certain situations, is just a bonus. The dude said in winter it might be 3.9 degrees when you wake up. The HRV system raises the temp to 16 so you need minimal heating to get it to 20 degrees. He says in winter there will be substantial heating up in the roof space. For the 60% saving power bills, it is also in their brochures, he says NZ universities research has proven it. And that HRV sells the most in Southland and Otago and that Otago uni recently installed 50 student flats with them in it. :clap	Nomad (952)
