Does the SolarWall system heat fresh air or recirculated building air?
Most SolarWall systems are designed to heat fresh air, not stale building air. In fact, many clients report on the tremendous improvement in indoor air quality with a SolarWall heater. If your building suffers from inadequate fresh air or make up air (factories) SolarWall is one of the lowest cost options for you. If your building is of the new air tight designs, you must provide for an adequate level of fresh air for your employees. (Occupational Health and Safety regulations are in addition to most building codes.) ^ TOP Q. My building will be leased and the tenant pays the heating bills. If you own the solar heater, you are likely entitled to the grants and tax incentives, and possibly the future carbon credits. One option is to install a Solar Ready SolarWall system without fans and let your tenant connect the fans to the SolarWall heater. The heating costs of the building will be permanently decreased, and this is a very marketable feature.
