Tankless Combi Boiler Installation

A Combi Boiler is both a High-Efficiency Water Heater and a Central Heating Boiler, combined (hence the name) within one compact unit. Therefore, no separate hot water heater is required, offering space saving within the home. It is an ingenious space-saving idea, and an increasingly popular choice in Ontario homes with hot water heating systems. The tankless combi boiler occupies 80% less space than a traditional floor standing boiler and tank water heater.

Space Saving Tankless Combi Boiler

Navien NCB is the first high efficiency tankless condensing combination boiler with the capacity to supply both heat and domestic hot water for larger homes — enough hydronic heat for a whole house, plus hot water to run two showers and a dishwasher all at the same time.

The Navien NCB saves installation time and reduces call backs. In addition, the NCB takes up 80% less space than a traditional floor standing boiler and tank water heater.

Energy Efficiency

New high efficiency condensing combi boilers are extremely energy efficient and have a Annual Fuel Utilization Efficiency (AFUE) of 95%. This means they convert more of the gas you pay for into use-able heat, saving you money on your fuel bills, compared to a standard efficiency boiler & water heater. Using less fuel also means you will reduce your carbon footprint and your impact on the environment.

Based on your requirements, we can size, purchase and install your new Combi System.

In the winter of 2019 my tankless water heater froze and broke. Amit promptly came out to replace it with a new standard water heater. Professional, and clean workmanship. Good price, good warranty.

My hot water tank started to leak over the long weekend and when I called NASA Heating and Air conditioning the following business day, Amit was able to provide me a quote for natural gas hot water tank installation over the phone. On top of providing me the quote, he was able to schedule the hot water tank installation the same day.
