Heat Transfer Duct Posted by: herbert 09 Jun 2011 9:52am

We have installed a 3-room heat transfer duct to transfer the heat from our fire place into the bedrooms. Does anyone know the power usage of the fan? The only information I can find is that it has a maximum airflow of 910m3 per hour.

Thanks

'Saver bulbs' Posted by: T J & S R Quirke 07 Jun 2011 12:32pm

I purchased these energy bulbs when a power company recommended 'buy 5 and get 5 free or something to that effect (been that long now)although when first switched on takes a few minutes to get to its full brightness 5 years no blow outs and still shining bright.

Make it interactive! Posted by: Matthieu Carrere 25 Oct 2010 11:46am

Great tables. The article on Saving Energy is very good as well.

Regarding the appliance tables, it would be great if they were interactive, i.e. containing the same information but with the ability to select only certain appliances and input a quantity (e.g. 4x 60W bulbs + 1x Fridge + 1x dishwasher, etc) to segregate energy use in one's own home.

An even greater feature would be to suggest alternatives to selected appliances, displaying potential savings in both energy and cost (e.g. 4x 60W bulbs could be matched with 4x 12W low consumption bulb, 1x 10yr old fridge matched with new fridge, and so on).

Final esults would then display actual consumption/cost versus potential consumption/cost with suggested energy saving features.


Another thing that would be great when talking about ways to save energy, would be to distinguish between people who live in a place they own, and people who rent. Realistic options for energy savings vary considerably between these two profiles.

Cheers,
Matt

'saver bulbs' ? Posted by: Jim Hayler 02 Aug 2009 12:12am

Late last year we bought 6 'saver' bulbs to date All! bar one have been replaced !!! Do not tell me that they last years !!!

Totally agree, I have lost 3 or 4 in the past year, these things are misleadingly overhyped. Even worse, it turns out the dangers from mercury contamination when one breaks could be much more serious than we have been told:

I am not buying any more, and only keeping some full spectrum daylight simulating ones I invested in before reading the above article (and which haven't failed yet). Try Halogen, or look into the emerging LED technology which looks to be far superior and safer, but as yet are not as powerful:

That's strange, we've had energy saver in all our fittings for 3 years now, with zero failures.

We replaced nearly all the bulbs in our house with energy savers, some as long as 9 years ago. Most are high usage, as we are seldom in bed before midnight, and up at 6.30, also tend to leave lights on. We still have most of the originals operating, probably replaced 10 out of 30

Like most things now, I am keeping dockets and some packaging which gives me come back if the product like those above fails. If the packaging says it should last 3yrs etc then so it should. If the retailer wont come to the party then surely the manufacturer will or should otherwise I will have them for false advertising. Its the same with toasters and other household appliances.

Ditto! on a purchase cost compared to the old ones and their short life they work out more expensive and they take forever to light up!

I am trying halogens as we have electronic switches, but they only seem to last as long as normal bulbs.

I've only had failures in the bathroom, and that only twice after about a year - they started flickering. I'm wondering if the steam reduces their life?
