Electric heat pump benefits

{{whyLabel}}: Understanding your current peak energy demand is essential for sizing the new system and calculating potential savings.

{{howLabel}}:

• Gather all gas/oil and electricity bills from the last two years.
• Identify the month with the highest consumption to find your 'design heat load'.
• Calculate your average annual heating cost to create a baseline for ROI.

{{doneWhenLabel}}: You have a spreadsheet showing annual energy costs and peak monthly kWh/therm usage.

{{whyLabel}}: Heat pumps are most efficient in well-insulated homes; poor insulation forces the pump to run at higher, less efficient temperatures.

{{howLabel}}:

• Check attic insulation depth (aim for at least 10-15 inches of fiberglass or cellulose).
• Look for air leaks around windows, doors, and rim joists using a thermal camera or incense stick.
• Verify if wall cavities are filled (check behind outlet plates if safe).

{{doneWhenLabel}}: You have a list of insulation gaps and a plan to seal major air leaks before installation.

{{whyLabel}}: Standard heat pumps work best with low-temperature emitters (35-45°C); knowing your current boiler's flow temp determines if you need a 'high-temperature' model.

{{howLabel}}:

• Lower your current boiler flow temperature to 50°C (122°F) on a cold day.
• Monitor if the house stays comfortable over 24 hours.
• If the house stays warm, your existing radiators are likely 'heat pump ready'.

{{doneWhenLabel}}: You know if your current radiators can handle low-flow temperatures or if they need upgrading.

{{whyLabel}}: Sizing by 'square footage' is outdated and leads to inefficient short-cycling; a Manual J accounts for windows, orientation, and local climate.

{{howLabel}}:

• Hire a technician or use a professional-grade DIY tool like 'CoolCalc'.
• Input exact window types (U-values), wall materials, and local 99% design temperatures.
• Ensure the result is in BTUs or kW for both heating and cooling loads.

{{doneWhenLabel}}: You have a certified report stating the exact BTU/kW capacity required for your home.

{{whyLabel}}: Refrigerant choice impacts future-proofing; R290 (Propane) is the 2025/2026 standard for eco-friendliness and high-temp performance.

{{howLabel}}:

• Select R290 if you have traditional radiators or live in a cold climate (GWP of 3, flow temps up to 70°C).
• Select R32 for cooling-dominated climates or if budget is the primary constraint (GWP 675, widely available).
• Confirm the installer is certified to handle flammable A3 (R290) or A2L (R32) gases.

{{doneWhenLabel}}: You have specified the preferred refrigerant in your project requirements.

{{whyLabel}}: Heat pumps require a dedicated 30-50 Amp circuit; older homes with 100 Amp service may require a panel upgrade.

{{howLabel}}:

• Check your main breaker for the total amperage (e.g., 100A, 150A, or 200A).
• Count existing heavy loads (Electric range, EV charger, Dryer).
• Consult an electrician if you have less than 40A of 'spare' capacity.

{{doneWhenLabel}}: You know if a panel upgrade (approx. $1,500-$3,000) is needed in your budget.

{{whyLabel}}: While upfront costs are higher ($10k-$20k), lower maintenance and energy costs often pay back the difference within 7-10 years.

{{howLabel}}:

• Use a 3:1 electricity-to-gas price ratio as a conservative estimate for 2025.
• Factor in a Seasonal Coefficient of Performance (SCOP) of 3.5 to 4.0.
• Compare the cost of a new gas boiler ($4k) vs. a heat pump ($15k) minus subsidies.

{{doneWhenLabel}}: You have a clear 'break-even' year calculated for the investment.

{{whyLabel}}: In 2025, programs like the US Inflation Reduction Act (25C tax credit) offer up to $2,000 annually for heat pumps.

{{howLabel}}:

• Check the 'Energy Star Most Efficient' list for qualifying models (aim for 17+ SEER2 / 9+ HSPF2).
• Download the necessary tax forms or rebate applications from your utility provider.
• Ensure the installation is completed by Dec 31st to claim for the current tax year.

{{doneWhenLabel}}: You have a list of qualifying models and confirmed eligibility for at least one major subsidy.

{{whyLabel}}: Quotes vary wildly; you need to compare not just price, but the proposed SCOP, warranty, and commissioning plan.

{{howLabel}}:

• Ensure installers are MCS-certified (UK) or NATE-certified (US).
• Ask for a 'room-by-room' heat loss calculation in the quote.
• Demand a fixed price that includes the removal of the old system and electrical work.

{{doneWhenLabel}}: You have three comparable quotes with technical data sheets attached.

{{whyLabel}}: Proper clearance is vital for airflow; poor placement can reduce efficiency by 15% and increase noise.

{{howLabel}}:

• Ensure at least 12-24 inches of clearance from walls (check manufacturer specs).
• Place the unit on a raised 'snow stand' or concrete pad to prevent ice buildup.
• Avoid placing it directly under bedroom windows to minimize noise disturbance.

{{doneWhenLabel}}: The outdoor unit is mounted level with adequate clearance on all sides.

{{whyLabel}}: Moisture in the refrigerant lines causes acid formation and compressor failure; a deep vacuum is the only way to ensure a dry system.

{{howLabel}}:

• Ask the installer to show you the 'Micron Gauge' during the evacuation process.
• Ensure it reaches below 500 microns and holds for at least 15 minutes.
• Do not allow them to 'purge' the lines with refrigerant instead of vacuuming.

{{doneWhenLabel}}: You have witnessed a successful vacuum test documented by the installer.

{{whyLabel}}: Heat pumps save the most energy when they run 'low and slow' rather than in short bursts.

{{howLabel}}:

• Set up 'Weather Compensation' so the flow temp adjusts based on outdoor air.
• Avoid 'setback' temperatures of more than 2°C (3.6°F) at night.
• Use a smart thermostat (e.g., Ecobee or manufacturer-specific) to monitor COP in real-time.

{{doneWhenLabel}}: The system is running on a steady heating curve with minimal manual adjustments.
