“The Bosch IDS 2.0 works with standard 24V thermostats, so homeowners don't need to invest in a new control system. It pairs with Bosch's own air handlers or third-party compatible units. Clean wiring and straightforward connections make for a smooth 1-day install.”
— NuWatt Energy Install Team
A heat pump increases your electricity usage by 3,000–6,000 kWh per year. Offset that cost with solar panels and power your heating with free sunshine. NuWatt designs integrated solar + heat pump systems for maximum savings.
The Bosch IDS 2.0 costs between $5,000 and $11,500 fully installed by NuWatt Energy. The final price depends on your home’s size, the tonnage you need, and installation complexity. Note that the federal 25C heat pump tax credit expired at the end of 2025, so there is no federal credit available in 2026. However, state rebates and utility incentives may still apply.
The Bosch IDS 2.0 is available in 4 sizes from 2 to 5 ton. A general guideline is 1 ton per 500–600 square feet, but proper sizing depends on your home’s insulation, climate zone, and layout. NuWatt performs a Manual J load calculation during your free consultation to determine the exact size.
Yes. The Bosch IDS 2.0 is rated to operate down to -5°F, making it a strong choice for New England winters. At 5°F, it maintains a COP of 2, meaning it produces 200% more heat energy than the electricity it consumes. Supplemental heat strips may still be needed during the very coldest hours.
The Bosch IDS 2.0 comes with a 10-year compressor warranty and a 5-year parts warranty. NuWatt also provides our own workmanship warranty covering installation labor. Be sure to register your product with Bosch within 90 days of installation to activate the full warranty.
The Bosch IDS 2.0 has an HSPF2 of 11 (heating) and SEER2 of 18.5 (cooling). For context, the minimum federal standard is 7.5 HSPF2 and 14.3 SEER2, so this unit is 47% more efficient for heating and 29% more efficient for cooling than the baseline. Higher efficiency means lower monthly energy bills.
The outdoor unit operates at 56 dB, which is moderate — comparable to background music or normal conversation levels. For comparison, the quietest unit in our lineup is 49 dB (Fujitsu Halcyon) and the loudest is 60 dB (Goodman GSZC18).
