Durable Heating Technology
The Elite Ultra comes equipped with the patent pending XtraTech Durable Stainless Steel Heating Technology, a proprietary heat exchanger. The high grade stainless steel ensures maximum quality at the heat of the boiler and resists corrosion to guarantee reliability for years to come. The innovative heat exchanger design provides an increase in water flow which creates more internal turbulence. The turbulence acts as a scrub to the internal walls and reduces heat exchanger deposits ensuring a longer lifetime in your boiler.
With a pipe surface that is up to 400% larger than conventional designs, The Elite Ultra ensures extremely low pressure water pressure drop, ensuring high performance. Equipped with an Xtra Tech stainless steel heat exchanger corrosion doesn’t stand a chance ensuring your boiler has a long lifetime and less maintenance.
Efficiency and Transparency
The Elite Ultra has a 11:1 turndown ratio that limits short cycling and provides more efficient energy consumption. This boiler comes with an outdoor sensor that, when used, can provide up to 96% thermal efficiency ensuring savings on your monthly energy bills.
See how your unit is working yourself! The easy to use interface showcases full text and an intuitive menu which you can easily set the temperature you desire, activate functions and even manage different heating zones with. Maintenance alerts appear when maintenance is needed or when something needs to be checked by a professional.
