Daikin VAM-GJVE Heating Reclaim Ventilator Review

Very efficient heating, haven't used to cool yet

I installed the 3.5 kW Daikin US7 as a combined heater and cooler for my new living areas, because of its environmental credentials. I’ve only used it over the winter, so can only comment on its heating efficiency so far, but have found it to be extremely rapid to heat up a room, reasonably quiet in its operation, and definitely cheaper to run than my old ducted gas system. I like the “comfort” setting, so that for heating, the vents point downwards and don’t create too much of a breeze, and when cooling, they oscillate, to help cool further. I had hoped that it might be powerful enough to heat not only the room it’s installed in, but also the adjoining rooms, that are connected through a double archway, but unfortunately this hasn’t been the case. This might be because there’s not enough airflow through this space, even when I use the boost mode, but this is the only reason I’ve why I’ve rated it four rather than five stars.

Amazingly efficient, reliable, quiet

As of writing we’ve had the smallest FTXZ25N unit installed in our main living area (approx. 50 m2) for 3 years (since May 2015) to heat and cool. It’s possible to check the overall total energy kWh used on the remote and it currently reads 1,585 kWh which equates to around $380 for 3 years at $0.24 / kWh.

We aren’t connected to gas and this is our only form of heating and cooling in the living area. Upfront cost is more expensive but well worth it. :).

Saving me

This air conditioner is saving me in the summer months. I can actually get a good sleep now that the house isn’t hot at night when I go to bed. It cools down the place very quickly. The only down side is that I can’t seem to get a good setting for when the house is already cool and I just want some circulation.
