What does a pump’s horsepower rating mean?

Pumps are rated by Continuous Operating Horsepower, the true runtime power, and Brake Horsepower, a momentary start-up rating used in marketing. Continuous HP determines actual massage strength.

Hot Tub Frequently Asked Questions

Q: Can any Sundance® Spa operate on 120V electrical service?

Some Sundance® models can run on 120V or 240V. Although 120V “plug-and-play” is simpler, most customers choose 240V for faster heating and better temperature stability in Canadian winters.

A 240V spa delivers roughly four times the heater output.

If using 120V, it must be on a dedicated circuit with proper amperage and no shared appliances.

Q: What’s the purpose of a circulation pump?

A circulation pump runs quietly 24/7 to filter water continuously and maintain your set temperature.

Spas without one rely on a large jet pump cycling on and off, which is louder and less efficient. Circulation pumps deliver better filtration, quieter operation, and lower energy use.

Q: Does a bigger pump give a better massage?

Not necessarily. Horsepower ratings often describe a brief start-up surge, not real operating power.

Effective hydrotherapy depends on jet design, plumbing efficiency, and water flow control.

A well-engineered spa with lower horsepower can outperform a poorly designed spa with a larger pump.

Q: What is hydrotherapy?

Hydrotherapy combines heat, massage, and buoyancy to support relaxation and recovery:

Heat increases circulation and loosens tight muscles.
Massage jets relieve tension and help accelerate the body’s natural healing process.
Buoyancy reduces body weight by up to 90%, easing joint pressure.

Hydrotherapy is widely recognized for reducing stress and improving overall wellness.

Q: What does a pump’s horsepower rating really mean?

Pumps are rated in two ways:

Continuous Operating HP — the actual horsepower delivered while running.
Brake (Marketing) HP — a momentary start-up rating used for advertising.

Continuous horsepower determines real jet performance.

Q: How many jets are adjustable?

Proper hydrotherapy depends on jet quality, adjustability, and placement — not the total number of jets.

Sundance® prioritizes ergonomics, targeted therapy, and purposeful plumbing rather than adding large numbers of non-adjustable jets.

Q: How often should I clean my spa?

Most spas should be drained and cleaned every 3–4 months, depending on usage and water care.

The process is simple and typically takes about an hour.

Q: Can a hot tub be installed indoors or outdoors?

Hot tubs can be installed indoors or outdoors, but over 90% (even in Canadian winters) are placed outdoors.

For indoor installs, ensure:

There is enough access for delivery.
The flooring supports the filled weight (a 3-person spa weighs ~2,500 lbs / 1,150 kg).

Q: How much should I expect to spend on a hot tub?

Hot tub pricing depends on size, features, materials, and build quality.

Sundance® offers a range of models for different budgets, and our team at Main Street Pool & Spa will help you choose the right spa for your home and lifestyle.

Q: What should I consider before buying a hot tub?

We recommend a wet test before purchasing. During your test:
