The NTI Vmax Plus Gas Boiler is an innovative system that offers some truly exciting benefits.

Compact Design Does Double Duty

Vmax Plus is a very small, extremely efficient unit that packs a lot of muscle: a boiler with a built-in water heater.  Heat and hot water in the same unit means one less appliance taking up space and costing you money.

Energy Star Most Efficient 2015 Boilers

This designation recognizes NTI Vmax as one of the most efficient products among those that qualify for the Energy Star program – an exceptional gas boiler on the leading edge of this year’s energy efficient appliances.   Its fire tube heat exchanger optimizes heat transfer, which maximizes efficiencies.  Vmax is economical to operate and will save money over the life of the boiler.

Built to Last

The Vmax uses a stainless steel down-fired heat exchanger, which ensures a long product life and years of home comfort. With fully integrated plumbing, It’s smartly engineered to be easy to install. Quick-connect components allow for easy service.

Choose Your Fuel

The Vmax comes factory ready for natural gas, but with its universal flue connections, it is easily converted to propane.

Exceptional value

The Vmax is competitively priced, which makes it unmatched in the industry.
