Efficiency and durability

NTI’s FTV heat exchanger is made of 439 stainless steel to ensure maximum durability. All fire tube heat exchangers are NOT made the same! Our fire tubes are dimpled to extract maximum efficiency without the need for inserts that will degrade over time.

Cross-series platform

To ease the serviceability of all our boilers, NTI rationalizes parts across our various series to minimize the number of different parts you need to stock and carry. More importantly, if you train on one product, you’ll automatically be familiar with the other NTI products.

On demand DHW (Combi)

With the FTV Combi, every homeowner can enjoy the comfort of endless hot water and space heating in one single appliance. It significantly reduces the installation cost and the mechanical room space required. Those are cost savings for you!
