I bought a demo/open box chlorinator from them. So far the product has been working well (one week) and it looked new in the manufacturers box when I got it. Communication with them was great. Price I got for the open box item was worth it. Would use them again. Thanks.

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.
