Customer: "SETS –Systems Tankless water heaters: If you have ever had a shower go cold on you, it is inherently evident why these water heaters are extremely desirable. Also, being able to turn on the dishwasher and the wash machine at the same time is a wonderful option when we are on a strict time schedule preparing the home in between clients. A definite amenity I would incorporate again."

IN HOT WATER NOW! 

Don't you hate to get to a vacation home and constantly be out of hot water?  The situation is much more intense on vacation:  more people; more dishes; more laundry; more showers.  Trying to get ready for a major event?  Showers start at 8 am to get 12 people ready with hot showers for an event at 7 pm.    It is a scheduling nightmare and not something you should have to contend with on vacation. 

We stayed at a B & B once that offered a "whirlpool" tub in the suite.  Eager to relax after the day's drive, I was extremely disappointed that the hot water only lasted long enough to fill the tub halfway.  An hour later, my lukewarm water mixed with the newly produced hot water for a belated bath.  Aggravating to say the least.

 This scenario is not in your future as a guest of the dome.  Jerry Morabito, President of Sets-Systems, Inc, is the hero of the hour.  His SETS Systems Electric Tankless Water Heaters  NEVER run out of hot water. http://www.sets-systems.com

 SETS Systems Electric Tankless Water Heaters have no storage tank; they heat the water as it is passing through the appliance.   It produces an endless supply of hot water while reducing the energy costs required to operate a conventional tank type water heater by up to 50%. The water heating system was improved with the assistance of NASA and patented exclusively by SETS Systems for residential, commercial and industrial applications.  

 We know the units are durable enough for the dome because of SETS contribution to the heroes of 9/11.  A mobile shower unit was established for the workers and volunteers at Ground Zero.  There were nine shower stalls and four sinks that offered an infinite supply of hot water using SETS tankless hot water heaters in each shower.   After three months of continual use, between 100-200 showers per day, the units were in perfect working order.   

So, enjoy your whirlpool tub and shower the sand away when you stay at the dome!
