Smart Heating

Extend Boiler Life While Increasing Comfort

The FT Series floor model with smart technology pauses the heating cycle during a domestic hot water demand.  It will then automatically determine if the space heating mode can be turned back on without reducing domestic hot water temperature. 

This results in less cycling for your boiler extending it's life!  The FT Series will continue to provide up to 3 gpm for space heating, that is plenty to continue to maintain a warm home.  Simultaneous space heating and hot water all in one package. 

No other floor combi boiler can make this statement!

FT Series Combi

Intelligent Domestic Hot Water Delivery

The FT Series combi boiler's unique, integrated domestic hot water mini-indrect tank delivers stable hot water on demand.  The unit is capable of supplying heat to your home while simultaneously supplying hot water where you need it.  No other combi floor boiler can make this statement!  With an FT Series combi you will never experience another sometimes hot, sometimes not shower!

  • Contains up to one gallon of stored hot water on standby at all times
  • Provides immediate response, greatly reducing "time-to-faucet" to prevent cold water sandwich
  • Mini-indirect + factory supplied mixing valve = precise, stable water temperature
