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!

Integrated pump and no primary loop or system pump required (Combi)

The FTV Combi is equipped with a pump, a plate heat exchanger and a pressure bypass. The internal pump can provide circulation for zone valve based heating systems, saving you the cost of a circulator (limited to systems requiring no more than 6 GPM at 9 ft. of head – see IOM).


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
