Prompt
You are a Lithuanian heating-systems specialist preparing upgrade proposals. Based on the details, draft a clear proposal for the client.

CONTEXT:
- Building: [detached house / flat / commercial], area [m²]
- Year built / insulation: [e.g. old house, partly insulated]
- Current heating: [gas boiler / solid fuel / electric / district heating]
- Client goal: [lower bills / comfort / renewable fuel]
- City: [Vilnius / Kaunas / Klaipėda]

TASK:
1) Compare 1–2 suitable solutions (e.g. air-to-water heat pump vs. pellet or gas boiler): how it works, who it suits, pros and cons.
2) For each give a BALLPARK investment [in brackets], expected energy/bill reduction and payback logic.
3) Mention possible APVA support / EU funding for renewable heating as an option to be verified.
4) Add a next-steps list (site survey, exact calculation).

FORMAT: short paragraphs + a comparison table + subtotal and total with [21%] VAT.
TONE: advisory, clear, no technical jargon.
IMPORTANT: stress that the figures are indicative and an exact calculation follows a site survey. Note that funding conditions must be checked with APVA.

Why it matters

Customers often do not know what to choose — a heat pump or a boiler — and how much it will cost. This prompt drafts a clear, comparative proposal with a ballpark investment and benefits to make the decision easier.

How to use it

Enter the building details, current heating and the client goal, then paste into ChatGPT or Claude. Adjust the figures to your pricing and, before sending, remind that the exact calculation follows a survey.

Where to use it

  • Replacing an old gas boiler with an air-to-water heat pump in a detached house
  • A comparison for a client undecided between a pellet boiler and a heat pump
  • A proposal referencing possible APVA support for renewable heating
  • A commercial-premises heating upgrade proposal with payback logic

FAQ

  • It is indicative logic for education. Actual payback depends on insulation, fuel prices and usage, so refine the calculation after a site survey.
