Don't waste your money
by Jeannine Giguere
We have had the Giant, tankless hot water tank for 5 years. It has been a nightmare from the beginning, the tank stopped working, there was an airlock but there is nothing in the troubleshooting to tell you this or how to fix it. We found out on our own. By lifting a valve on the side to drain the water out. We tried and tried to find a service person but there are none to be found, you are left on your own. Good luck as this system is enclosed and you cannot reach anything inside. We found out, by reading that these tankless systems are not recommended for wells. If you are on a well do not use these, as hard water will build up and destroy the pipes.
Our pipe burst last week, water throughout the system.. the tank is done. It will corrode over time. You cannot access this pipe nor change it. Again... there is no servicing personnel to call. Waste of money. We are in the process of putting a large 50-gallon water tank in, which cost a lot less and will last so much longer. Yes, these tankless systems sound good but trust me they are a huge headache. DO NOT PURCHASE!!! I have taken pictures of the inside... as you can see/ or not how difficult this system is to fix... again there is no support once you purchase...
