Residential Rebates
Step one: Eligibility
- Homeowners must be on residential rate schedule 503 (work was completed at a residential address, not a commercial business)
- For heating and weatherization rebates, homeowners must use natural gas as your primary heat source (not a back-up for an electric heat pump); or
- For water heating rebates, homeowners must use natural gas as your primary water heat source
Step two: Select your Project Type
Step three: Find a Qualified Trade Ally Contractor
Click for a directory of Trade Ally Contractors in your area who meet CNGC program standards and are familiar with our program requirements and rebates. Or call us at 866-626-4479.
And remember it’s a good idea to always get 3 bids for any project you’d like to engage in.
Step four: Submitting paperwork
Taking a little extra time to ensure your paperwork is complete and accurate helps the rebate process move forward and helps you get your rebate even faster.

What is a ``combination space and water heat system?``
It is a high efficiency appliance that uses condensing technology to heat water and distribute it for space heat and domestic hot water use as needed.
The most efficient combination system uses an indirect-fired water heater; the boiler feeds a heat exchanger inside a storage tank (typically 50-100 gallons), transferring heat to the potable water. This system takes advantage of the already-hot boiler during the heating season. Condensing boilers have a long life, 30 or 40 years compared to 10 to 15 years for a standard storage-type water heater.
The system can be configured to provide space heat via hydronic heat (like piping in the floor, or radiators placed throughout the home), or a hydronic Air Handler can be installed for heat distribution
95% AFUE minimum
