DVS...HRV....Smartvent....Air Systems...

I would be interested in costs etc too - cause our power bill was $350 last month - first month since Oliver came into our lives!

we have hrv dont get one they are crap my best riends mum has a dikin heat pump and its great

We have HRV. We find it's great for the condensation and also we no longer have a stuffy bedroom with 2 adults and 2 babies sleeping in there.
I no longer feel the need to open windows during the day either as the house is getting ventilated.

However having recently gotten a smartvent pamphlet in the letterbox we would have gone for that one with the additional 'Heat Transfer' Kit which would take the heat out of our warm sitting room and transferred it around the rest of the house.

We have just got DVS and LOVE LOVE LOVE it.

It cost $2800 I think for 2 vents and a heater in the hallway.

We are looking at getting a Moisture master.

These have an optional heating unit that can take the chill off the air once the temp in the ceiling space drops (No it does not "heat" as such) It has 4 levels of heat options. You can also get the Heat transfer option as well, and they have another option that enables you to bring in cool external air during summer.

I think that running cost is comparitable with the DVS and HRV, except for when you add in the heat option. That bumps it up to about $1.00 per hour, but you wouldn't run that full time anyways..


The main seller for me on the Moisture Master was the Heat Transfer option. We have a Kent fireplace n our lounge and the lounge gets REALLY hot, whereas the back bedrooms are REALLY cold...

We have an HRV and do find it quite good...

The only thing that we're not enjoying is the fact that the air is now SO dry that our eczema is being affected, as eczema is not actually an allergy related issue, but has to do with the fact that the skin lacks the moisture necessary to function correctly. So the dry air is really rather irritating for us!

No condensation is good though, and as Tishy said, the air flow is another positive thing.

Others have mentioned it, but I'd recommend spending a bit more and getting something with a heat transfer kit. They're not really a means of keeping a room warm, but it definately takes the chill off and warming the air up a bit more, therefore reducing the need for a heater... So whereas it may cost a bit more up front, in the long run they're a great investment and save you a few $$ on heating.

sounds great ann, our house has very wet windows and kayla's room is quite damp- she is often sick... thanks to the house sick programme for opening my eyes a bit and making me realise that it could be the house!!!

not so good with the eczema issue though serenity, we have eczema in our family! argh! gotta weigh it all up now, i hadnt thought about it drying out the air tool much!

guess you cant win!

We have a DVS system in our home and our house is over 50 years old so it can be freezing! The DVS does keep it very dry and takes the chill off the air. We have very little, if any condensation when the DVS is on.

We switched the DVS off accidentally last winter for a few weeks and our windows were dripping with condensation and water was running down the walls under the window sills. So that prooved to us that it is doing something when it is on!

Im so confused with what they all do....

I basically want something to stop the condensation and to "move" warm air from the hotter areas of the house which mostly occurs naturally as all living areas are pretty warm throughout summer and winter...just our rooms are all cold......... Plus I dont get how it would work if it was a freezing cold day and there was no sun would it then take the GAS heater heated air from the Living areas and pump it through to the other rooms?????

So would the heat transfer thing stop the condensation too?? Sorry for some reason having trouble getting head around it!!! LOl (hmm maybe pregnancy)
