Underfloor heating has an 8 hour turn on/off lag time. It's nearly useless out here in the SF Bay area, since we go from short sleeve to jacket weather every day, almost year round. Our air source heat pump is much quieter than old air conditioners. For efficiency, it has a giant, slow, variable speed fan. It's usually not running anywhere near full speed, and is still quiet when it does. Similarly, the blowers in the ducts are variable speed. |
