   The Venmar "Solo " or "Duo" coupled with their "Ultra" central wall control are my present favourites and have been for about 10 years. Do not accept their stripped down (for contractor lowest costs) "Constructo" model!!! They manufacture for other companies such as Carrier, I believe. See the Home Ventilating Institute's evaluation of various units. From the tech data, you can tell when a Venmar is being sold by a company under their own name- the data is exactly the same as a Venmar,

   The Venmar only has one central controller. I was thinking I needed one in the baths and Kitchen? I also looked at the hepa 3000.

    Thanks for your help.

   I would still use a bath fan controlled by a timer and possibly an exhausting range hood also instead of hoping for the HRV to do all the work. An HRV is a general air quality device while the bath fan and range hood are spot or area ventilators.

   When you call for high speed for 1 bath, the unit is drawing from the laundry and 2-3 other full baths or washrooms and the kitchen. One large house I saw in 1993 still had a wet master bath from morning showers when people came home for lunch....it was the farthest exhaust from the unit. In 1981 I was using HRV's for all ventilation in homes (recommended by manufacturer) but by 1984 was back to installing bath fans and the odd venting range hood also.

   For the unit I would choose a Solo or Duo with the Ultra (7 function) control. The HEPA 3000 is a big box over-the-counter unit for the homeowner. I don't know of any dealers who install it. It's not a bad unit but I would want the better unit control with more operational options
