Hybrid — keep gas + add heat pump
Some homeowners want both: keep their existing gas boiler AND add heat pumps. This is a valid scenario.
How it’s classified
Section titled “How it’s classified”This is a non-decommissioning job. The boiler is untouched.
- No decommissioning bill
- No mechanical permit (boiler remains primary heating source)
- Electrical permit only
- Not eligible for the Con Edison Clean Heat rebate or NYSERDA / EFS financing
See Non-decommissioning install for the full process.
Multi-fuel setups on the same thermostat
Section titled “Multi-fuel setups on the same thermostat”Sometimes the homeowner asks: “Can my heat pump cool, but my gas boiler still heat, both controlled from the same thermostat?”
Sunny does not do these multi-fuel thermostat setups. It is technically possible but we don’t dabble in it.
What we do support
Section titled “What we do support”- If the homeowner already has separated thermostats for heating and cooling, they can use the new heat pump (or central air) for cooling only and keep their existing thermostat for heat
- Each heat pump unit gets its own thermostat tied to that unit
See Central air — multi-fuel setups for more on the thermostat scenario.
