Poolman is offering $50 off a new variable-speed pump for your San Diego pool. By installing one of these, you'll save money on your electric bill as well.

Buying a new pool pump is an excellent way to tackle energy conservation. Pentair stated that a variable-speed option can reduce the energy costs of running a swimming pool by 90 percent, due partially to the fact that pumps consume more energy than any other piece of equipment.

According to Pacific Gas and Electric Company, California has adopted energy-efficiency regulations that affect the sale of inefficient pumps and motors. The California Energy Commissions' Appliance Efficiency Regulations prohibit the sale of single-speed pool filtration pumps. However, these pumps work differently from single-speed pumps as they're far more efficient due to the adjustment in horsepower.

Also, variable-speed pool pumps are programmable to any speed you wish. This allows you to choose what works best for your pool's size and shape. The benefit of adjustable speeds is that the pump doesn't need to run with full pressure at all times.

Furthermore, a constant-flow variable-speed pump allows the user to dramatically reduce noise compared to single- or two-speed pumps. Due to the reduced wear and pressure, not only will the pump last longer than the other choices, but your pool's filter, chlorinator, heater and other equipment will not need to be replaced as often.

The average variable-speed pool pump may cost more than a two-speed pump, but the energy savings will more than make up for the difference. According to Pentair, the cost to run a variable-speed pump can be as little as $200 in most cases. After five years of using one of these pumps, you could save about $1000, which costs just over the price of running a single-speed pump for only one year.
