  • These units have very high output at a very affordable price.

  • They are fully modulating units - they sense the hot water demand and only use enough energy to satisfy that demand.

  • 100% Efficient with a 15 Year Warranty, they have long life expectancy without a high cost.

  • Ultra Boilers have Outdoor reset

  • Combination boilers with a 50 or 70 gallon domestic hot water storage tank.
