Welcome to our forum.
I just have to jump in here. Before I start, it's great to hear from Superted and Rick! This board needs more Coleman Spa owners/dealers, ect. on line. I’ve been selling Coleman Spas since 1994 in North Dakota. Yes that is right above South Dakota, and we are not the end of the earth!! However on a clear day if you stand on you car you can see it from here. Sorry, a little N.D humor. Zz you are so right in your observation comparing our house insulation to the insulation in spas. We make our houses more efficient by putting insulation on our walls and attic. We install air tight windows and put high efficiency furnaces inside to heat our homes. This seals cold air out and warm air in… This is what Coleman’s Thermo Lock technology does. They start be spraying 2 to 4 inches of high density foam on the spa shell. The tubs have a solid ABS pan bottom with 1 ¼” polystyrene bead board over that. The beadboard has a lining of reflectex. Reflectex is a silver reflective foil that will reflect radiant heat from the spa’s plumbing and equipment back up onto the spa shell. The cabinets are maintenance free Duramax, which is mounted on ABS board for strength than attached to the 1 ¼” poly-beadboard and lined with the reflectex. Coleman recaptures all of the heat generated by the equipment because we have a sealed, insulated, heated, dead air space all the way around the shell of the tub. Just like the technology in a house we seal cold air out and warm air in. The whole hype on the board about needing full foam to support plumbing is not at all true. First of all if that were the case, why would Coleman have a 5 year plumbing warranty? They would go broke fixing all the leaks. Second, take a full foam tub like Sundance. (I’m not picking on Sundance I think they have a good product!) look at the space they have their equipment in. What you will see is plumbing coming from the foam and into the equipment this is totally not supported in that part of the spa. How does that work? The Thermo Lock also insulates the equipment noise. When we do tradeshows and fairs I always check out the competition, our spas are always quieter than full foam spa’s. My spa is outside on the northwest side of my house with nothing around it. The winters here are cold!!! And long, it snowed two nights ago May 25th. My spa runs me around 25.00 to 30.00 in the coldest winter months, and we use our spa all winter long. Here are some websites to check out on foam insulation.http://www.eere.energy.gov/consumerinfo/refbriefs/ed3.htmlhttp://www.buyersinspectionservice.com/faq-insul-allabout.html Spahappy
Additionally, the pumps have operated flawlessly. If the manufacturer who's spa you buy is built this way, you can be assured that they will take the time to use equipment that works in a warmer environment
Nobody can tell you how to negotiate for the purchase of your spa, dazedandconfused. It all comes down to the dealer and you. If you don't like the price the dealer is offering, try making a counter offer, and go from there. They may stick to their price because they are offering you their best price. Best thing to do is shop around, see what comparable spas are going for in your area, and not get too hung up on price. If you make a reasonable (from the dealers perspective) offer it will be accepted. There are way more important factors to consider when buying a spa. Believe me, once you have your tub up and running, you QUICKLY forget about what you paid for it.
