What Makes Our Tanks Better?

We only make our tanks using 2205 Duplex stainless steel because it is the best material available

  • 15 year warranty. You can have confidence in knowing your covered. 
  • Competitive and fair pricing.  We are always trying to make the best tank for the the fairest price. Compare our tanks to the rest because we know our tanks are great value and will save you money long term due to their higher effeciency and long service life.
  • Made from the best quality Duplex stainless steel available. The Duplex stainless steel used to make Exegi tanks is imported from Sweeden and made from over 90% recycled material. Exegi Duplex tanks will outlast any 316 or 304 stainless steel tanks meaning you will save money. 
  • Industry leading heat loss due to superior spray foam insulation.  Less heat lost means less heat that needs to be boosted into the tank saving you money at the same time as lessening your invironmental impact.
  • Multiple port locations and over sized ports to allow for larger applications and future upgrades to supply pipe sizes. Why not install a tank that is future proofed? No matter what application you have, we can make a tank to suit. 
  • Dedicated drain ports. Why is this important? Drain ports enable proper draining of the tank during servicing and will increse the life of the tank. Most companies don’t have these as selling a replcement tank is good for business. We think differently. 
  • 3 removable sensor ports. More options for increased applications and accurate temperature readings. 
  • To suit any application. Suitable with any heat source including solar thermal, Heat pumps, wood boilers, gas boilers and also comes with a back up element if needed. No matter how you plan to heat your water, we have a tank that will do the job.
