1. What is SEAI Heat Pump Calculator?

The SEAI (Sustainable Energy Authority of Ireland) Heat Pump Calculator estimates the performance and energy savings potential of heat pump systems based on SEAI energy standards and typical performance factors.

2. How Does the Calculator Work?

The calculator uses SEAI standard calculation methods:

Where:

• \( \text{Heat Demand} \) — Annual heating requirement in kWh
• \( \text{COP} \) — Coefficient of Performance (typically 2.5-4.5)
• \( \text{Savings Factor} \) — Based on system type and building characteristics

3. Importance of Heat Pump Calculations

Details: Accurate heat pump performance estimation is crucial for assessing energy savings, payback periods, and environmental benefits when considering heat pump installation.

4. Using the Calculator

Tips: Enter your building's annual heat demand, select the appropriate system type and building type, and provide the expected system efficiency (COP). The calculator will estimate annual output and potential savings.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical COP for heat pumps?
A: Air-source heat pumps typically have COP of 2.5-3.5, while ground-source systems may achieve 3.5-4.5 depending on conditions.

Q2: How do I find my annual heat demand?
A: This can be estimated from your energy bills or through a BER (Building Energy Rating) assessment.

Q3: What affects heat pump performance?
A: Performance depends on outdoor temperature, system design, building insulation, and heating distribution system.

Q4: Are there SEAI grants for heat pumps?
A: Yes, SEAI offers grants for heat pump installations in Ireland when installed by registered contractors.

Q5: How accurate are these estimates?
A: These are preliminary estimates. For accurate assessment, consult with a qualified heat pump installer.
