HRV

well, we got our HRV system installed today, got to 43 deg in the roof so far.... Hope to have nice cool air circulating around the house tonight.

Not sure if it is a similar system but we have a DVS installed in our place, great at getting rid of the condensation, but we have to turn it off during the hottest hours of summer or it blows hot air in from outside!!

So do these things actually work?

What about the systems that circulate warm air around the home. Especially DIY kits??

As far as condensation goes, we used to have water literally pouring off our windowsills in the middle of the night, the dripping used to wake us up! A dehumidifier couldn't cope with it. We got the DVS installed, and on its own it cuts out most of the condensation problems. With a dehumidifier as well, not a problem at all.

Ours is a 1950s Huntly brick house. We went for the DVS after a friend with a similar house/problem recommended the system.

Interesting thoughts for a new home builder in NZ , but could you both expand on the initials please?

Thanks MM.

oskatd, how old is your house? I am just asking on behalf of Swaggie as I would have thought that newer places were less likely to need these sorts of systems if they are well designed?

When we lived in the city we had a DVS installed and it was brilliant, we had no condensation after installation, and it helped push heat around the house from the fire.

My house I am building comes with one in the plan so I am interested in how these things work. Building with a house company.

Tigger, our house was built around 1928, however we have reroofed, reclad (including insulation in all exterior walls) and put new (ali) windows in - it was an old bach from the mount that was relocated. The HRV and DVS are similar, the HRV just circulates the air a bit faster (2.5 x an hour as opposed ot 1.5 with DVS). The HRV has more automatic features too, and costs a bit more. we have double glazing in our bedroom windows so no problems with condensation, but it was just the warming in winter, and ventilation in summer, and the fact that it dries the whole place out, and the filter to provide pure air (gets rid of pet odours etc). future proofing the house, the call it!
lots of people install at construction, makes it easier for the installer i guess!

What ya need are solid brick built house with cavity wall insulation, double glazing and proper central heating! Then ya'll be warm as toast!

Under floor heating is great too, very efficient but it would need to be pipes layed under floor with hot water running through! beeyootiful!

that is the plan MM, just need to win lotto....

Well ya can't win it this week, it'd my turn!
