Heating your home with fossil fuels doesn’t just keep you warm-it creates emissions that warm the planet. Or install the tubing for a ductless or hydronic in the event that it might be required in the future.A wintry Montreal street. Every situation is a bit different, and you may find that your house performs very well sans AC. In a well built home, a heating system that turns off "now" is far more effective.Īlso remember that high wall insulation increases transmittance time (the time required for heat/cold to penetrate the building envelope), and proper shading in the summer, and "summer bypass" on the HRV will all help with the cooling situation at little or no extra cost. The slab will stay warm for hours after the thermostat has said "off". The other problem with hydronic in a superinsulated house is the lag time. This could be baseboard heaters, for example, which may not be ever used. The problem with using a ductless for heat, is that the OBC does not recognize this unit as a primary heat source, so something else needs to be present. We depend on high performance windows (and lots of insulation in the walls (like you are doing). We installed a hydronic system, but it has never been turned on. We depend on solar radiation (big windows) for heat and cool breezes in the summer for cool. We have no active heat source in the house. Lance, We have a super insulated house (passive compatible) in a similar climate. The CERV has a recirculation function that pairs well with mini-split heating. The Minotair product is especially designed to manage humidity. Two products I'm aware of - CERV (conditioning energy recovery ventilator) from Build Equinox, and Boreal 12000 from Minotair. The capacity, both heating and cooling, is low, so you couldn't heat your house all year with one of these, but for a home with low cooling load, a heat pump ventilator might be just the thing. Ductwork is similar to standard ventilation ductwork, but you may need to design to satisfy cooling loads, not just ventilation needs. In the winter, the air that is supplied to the house can be warmer than the air extracted from the house, and in the summer the supply air can be cooler than house air, and cooler than ambient air. Want to distribute AC through your ventilation ductwork? A heat pump ventilator does what an HRV/ERV does, but with a heat pump instead of a passive heat exchanger. “Once you’ve installed your air conditioning system, you can use…ĬERV - just the thing for a little AC and a lot of ventilation There are three basic varieties: a conventional air-source heat pump with ductwork to distribute the conditioned air a ducted minisplit using a smaller, more localized duct system or a ductless minisplit. One of several types of air-source heat pumps would be a good choice for a superinsulated house, GBA senior editor Martin Holladay suggests. Use an air-source heat pump for both heating and cooling Is that plan feasible? That’s the topic for this Q&A Spotlight. “It would be nice to avoid doubling up on the amount of ductwork running through the house,” he says. Peters would like to use the ducts for his heat-recovery ventilator to supply cool air in the summer. A large portion of the second floor will be open to the first floor (above the living and dining room areas and main staircase), leading me to think ductless minisplits would be a bad idea.” “Finished plans should be around 2,500 square feet. “The house will be superinsulated (~R-40 walls, R-60 attic, R-20-30 below grade) with southern exposure and proper window shading to limit solar radiation,” Peters writes in a Q&A post at GBA. ![]() He’s currently planning to use hydronic in-floor heat on all three levels of the house, plus either a heat-recovery or an energy-recovery ventilator with its own ductwork. That’s the situation Lance Peters faces as he plans a new, two-story house in Ottawa (what Peters assumes is the U.S. But because there are no air ducts with a radiant-floor system, air conditioning must be added separately. Radiant-floor heating systems are unobtrusive because the plastic tubing that distributes hot water around the house is buried in or under the floor. ![]()
