Most Portsmouth homes heat with oil. Here is what switching to a heat pump looks like financially.
Portsmouth has 6,400 heating degree days (Climate Zone 5). Cold-climate models are recommended for reliable performance below 5°F.
500 cooling degree days. Light cooling needs. The real value is in heating efficiency.
We install heat pumps with our own crews across New Hampshire. No subcontractors, no lead selling.
Our crews live in New Hampshire. We know Eversource NH rebate paperwork, local permits, and Portsmouth building codes.
Climate Zone 5 requires proper equipment sizing. We use Manual J calculations for every Portsmouth installation.
We handle all New Hampshire rebate applications for you. NHSaves paperwork, utility filings, and income-eligible programs if you qualify.
No overselling. We match the heat pump to your Portsmouth home's actual heating and cooling load, not a one-size-fits-all formula.
NuWatt's New Hampshire team will assess your home, recommend the right system, handle all rebate paperwork, and give you an honest price.
