FAQ
Our expert staff answers customer's most asked questions.
What is the difference between E-commerce (EC) and Trade pricing?
E-commerce pricing is our standard online retail pricing available to all customers. Trade pricing is exclusively for pool maintenance professionals and typically offers better rates. To get Trade pricing, you'll need to request a personalized quote.
How many BTUs does my heater need to heat a pool or spa?
The ideal BTU rating for your heater depends on your desired heating speed. A 200 BTU or 250 BTU heater is suitable for a spa or pool, while a 400 BTU heater will heat your pool and spa more rapidly.
Does a solar panel for my pool effectively save energy?
Absolutely! The installation of a solar pool heater can significantly reduce your swimming pool heating costs, providing an energy-efficient solution.
