I have an outdoor type 300 gallon hot tub. Using it in the winter is a little cold, and I am wondering if there is a way to turn it higher. Currently it will not go above 104 on the setting, however it does goto 105 in actual practice. The hi limit temp setting is 115. Anyway I can adjust it to go up to 110 or so? still leaves 5 degrees to avoid false tripping the hi limit. I believe the heater is a 2.5KW one so I think it can maintain higher temperatures, the setting panel just wont let me... yet. Thanks for help-Josh

My husband and I want to build a deck and have a spa sunk into it. We started looking yesterday and don't really know what to ask. First, I couldn't get over how expensive they were (compared to the commercials you see on TV with them starting at $1600). We don't want/need anything too fancy and we only want it big enough for 4-5. How much should we really be spending? (So far it looks like around $5000 - we live in IL if that makes a difference). Are there companies that we should avoid? I've asked about maintenance, service, and utility costs. What else should I be considering? The ones we've looked at have anywhere from 17-35 jets. Like I said, we don't need anything extravagent -- how many are enough? Help!
