Energy Recovery Ventilator and Ductwork

A lot has happened in the last month or so, although the progress seems glacial to us since at this point we are itching to move in. We have a lot to catch up on blog-wise. So watch out for a spate of new posts.

Ductwork.

We're putting in an Energy Recovery Ventilator (ERV). Since we have steam heat, this is the only ductwork being installed in the house. The ERV will be installed in a small room off the attic. The supply is located at the bottom of the attic stairs on the 2nd floor. The returns are located in the bathroom, kitchen and media room. We struggled a lot with whether to buy an ERV or an HRV. We got advice from our Energy Rater, an independent rater in southern Ohio and our HVAC subcontractor that the ERV was the better option because it deals with humidity, while HRV's deal only with heat recovery, so it's more efficient. This will allow the house to be more humid in the winter, when the air is dry; and less humid in the summer. This works well for the Cleveland climate. The ERV itself hasn't shown up yet, but here are some exciting photos of the ductwork to tide you over
