Up to 95% AFUE from one unit that handles both heat and hot water — high performance, lower bills.
A stainless steel heat exchanger and compact wall-hung design that saves up to 80% of the space.
Wi-Fi connectivity and an easy-to-use control interface.
Whole-home heat and on-demand hot water that never runs out — from a single unit.
A Navien combi-boiler supplies both central heating and on-demand domestic hot water from a single wall-hung unit — enough hydronic heat for a whole house plus hot water that never runs out. It's the space-saving upgrade Long Island homeowners love.
Compared with a floor-standing boiler paired with a separate hot-water tank, a Navien combi-boiler takes roughly 80% less space — freeing up your basement or utility closet while delivering higher efficiency.
Need more capacity? Navien combi-boilers can be cascaded with a Navien NPE tankless water heater for extraordinarily large hot-water demand — ideal for big homes, multi-bath households and light commercial use.
Up to 95% AFUE, ENERGY STAR certified and backed by up to a 10-year heat-exchanger warranty, with an elegant, clean appearance and easy-to-use controls — a smart choice whether you're replacing old equipment or building new.

I have nothing but good things to say about this company and their employees! I needed emergency service at 4am and they responded within a half hour! And even at that early morning hour they were pleasant and efficient! I have since signed up for a service contract with them and am confident that the excellent service will continue.
Used them for over 6 years. Very neat professional installation and when I did have a problem they have been very responsive. Brian and his crew are professional and easy to deal with. Highly recommend!
I have been using this company for years and have recommended them to all my friends and family that needed this type of service. Have not had one person complain I gave them a bad recommendation. Great company - Great Service - Great Workers!
