New FL building codes require 2 speed pumps etc [Florida only]
I saw somewhere else today that there has been a recent change in building codes in FL that (among other things) require any pump larger than 1hp to be a 2 speed pump... Here's the bullets:
Chapter 4 of the 2010 Florida Energy & Conservation Code provides the specifics, which requires the following: - Residential filtration pool pump motors cannot be split-phased, shaded-pole or capacitor start-induction run types.
- If the total horsepower (HP) of a residential filtration pool pump or filtration pool pump motor is one HP or larger than the pump and pump motor must have at least two speeds.
- Residential pool filter pump controls, for use with a multi-speed pump, must be capable of operating at a minimum of two speeds.
- Default pool filtration speed must be a speed that results in a flow rate that will NOT turnover the pool in less than six hours, and any high speed override must default back to the pool filtration speed in less than 24 hours. This allows solar pool heating systems to run at higher speeds during periods of usable heat gain.
- Thermal efficiency of gas and oil-fired heaters must not be less than 78%.
- Heat pump heaters shall have a coefficient of performance at low temperature of not less than 4.0 (COP).
- Natural and LP gas-fired heaters shall not be equipped with constant burning pilots.
- All heaters shall have a readily accessible on-off switch that is mounted on the outside of the heater and that allows shutting off the heater without adjusting the thermostat setting.
My understanding is that it's "House bill 849" that's made the changes. I found it interesting, because under the new rules the 2hp pump I replaced last year with a similar model would have been prohibited.
