| 459207 | 2006-05-31 04:18:00 | Don't dehumidifiers use lots of power? Affirmative. I bought a dehumid from the Warehouse a couple of years ago but returned it when I calculated the cost of running it every day. |

| 459208 | 2006-05-31 04:25:00 | I wonder if anyone has worked out the relative costs of replacing single glazing with double glazing to that of installing/running other forms of condensation control like roof ventilation systems or de-humidifiers? Murray?? | Terry Porritt (14) | ||
| 459209 | 2006-05-31 05:13:00 | Double glazing would cut down on the amount of condensation formed on the windows but wouldn't make any difference to the amount of moisture still in the air if you don't take other measures to reduce it. Result: a damp, mouldy, unhealthy house and contents. |

| 459210 | 2006-05-31 05:17:00 | T . P . Yeah, I was thinking along the same lines, at least for the commonly used rooms, but wanted to get a bit more of a handle on what was going on . To answer your question, I'm not sure :eek: I vaguely remember a rule of thumb that double glazing adds 40-50% to the manufacturing cost of aluminium exterior joinery (that being the proper sealed stuff) . I could spout some figures for house lots of ext' ali joinery, but they're a few years old now, at a very rough guess, I'd say a ranchslider, a couple of large windows, and a couple in the 1 . 4x1 . 6M regions and a door will set you back about $5-6k . As a retrofit, you're going to have to pay a glazier to fit the glazing on-site, which is already build in to the cost of new joinery, and new glazing beads to accommadate the extra width of the glass units (that's if the extrusions will accept dbl glazing without modification or at all) . Be aware, if you have more than a few large units that are witin 500mm of the floor, you'll get stung by the cost of safety glass and, if the exterior side is also accessable, that will also need safety glass . Ouch! So, it doesn't look that great a propositition, but I'm a big fan of double glazing not just because of the savings in electricity (winter and summer if you have aircon) but the more intangable benefits like comfort, less noise intrusion and of couse less likelyhood of condensation and the overall energy savings to the country if double glazing was encouraged more by the powers that be . Nobody that I know of, who has had double glazing fitted, despite the cost, have regretted the the decision . |

Result: a damp, mouldy, unhealthy house and contents . Foxy, it really depends on the reason for the humidity/condensation . Relatively warm air with average humidity % will always find a willing dew point on glass that is close to the exterior temperature if that temperature is low enough . Of course, as you say, highly moisture laden air, will reach dew point at a much higher temp and therefore condense on surfaces that appear to be quite warm . It's all to do with pressure and exitement . :rolleyes: If for no apparent reason, the windows run and drip, then double glazing will helpo a great deal . If the wall drip too, then you might want to start looking for additional factors, like moisture sources and poor insulation . |

| 459213 | 2006-05-31 07:01:00 | It would be easy enough to work it out: Number of KW of the appliance x price per KW that you pay to your electricity supplier x number of hours you run it . |

| 459214 | 2006-05-31 07:10:00 | If you do decide to get a stand-alone dehumidifier to cope with the immediate problem, then make sure you select a model that allows you various usage options which will help with power consumption. I have a De Longhi which gives allows you to control the choosen humidity level. It also has an option to run as a combo heater/airfan. Make sure the power of the machine is sufficient for the area of your house. I use mine to cover the whole house, rather than a smaller one which can only cope with room sized areas. Dehumidifiers also work better the warmer the ambient air temperature is. For this reason, and for noise issues, leave the dehumidifier running during day hours and turn it off at night. You may only have to run it every 2-3 days to control air moisture. | Jen (38) | ||
| 459215 | 2006-05-31 09:51:00 | Hi Greg We bought one last weekend funnily enough . As usual I did lots of research (being very canny with the money !) . It does not always mean that I make the right choice . However I did start with Consumer mag and found that their latest overview was 2004 - not all that recent but not to be ignored . They recommended Woods (at the Warehouse), then Evantair . They said that de'Langi was not the best . I then went and spoke with people at Bond and Bond, Noel Leeming and Harvey Norman . Incidentally the quickest and best salesperson was at Bond and Bond, but then it can be the luck of the draw, where you go and who you happen to land on . Mitsubishi seem to be top of the range and have all the bells and whistles . For instance, you can preset to switch off at a specific time . However will you use the bells and whistles ?? At the lowest price $700+ --- Up to top of their range $900+ you have to be really serious and demanding . We settled for Evantair - now sold by The Warehouse . It is a bit noisy but then we run it in the master bedroom during the day and the lounge at night, while we are sleeping, and the noise does not worry us . It is only a week since we bought, so if you like, can update you in a further couple of weeks . And the price . . . it was $399 (there is also a $299 model) . It is slimline which is important for us -- if I remember correctly the Woods is about one third longer in depth -- which is a lot unless you have lots of space !! Let us know how you get on ! Have got to say it is comforting to get up in the morning and see the lounge windows completely clear with no moisture running down and pooling in the window gutter . Misty :thumbs: |

| 459216 | 2006-05-31 09:55:00 | We have 2 dehumidifiers operating continuously through winter- one upstairs and one downstairs. Downstairs is a Mitsubishi which sucks up water like you wouldn't believe. Unfortunately it developed a intermittent buzz that sounds like a 747 taking off (thats why its down stairs). Up stairs is a Delongi which is fairly silent but has to operate on a high setting to remove significant amounts of water. Power usage is significant adding about $50 to the monthly power bill. |
