Disclaimer

HeatWise Home calculators and guides are intended for informational planning only. Outputs are estimates and should not be treated as final technical advice, quotes, or guaranteed outcomes.

Estimate-only outputs

Calculator results are based on user inputs, general assumptions, and simplified models. They are not a full room-by-room design, MCS-style survey, or property-specific engineering assessment.

Why real results vary

Heating costs and savings can vary significantly due to differences in:

• Property age, size, construction type, and insulation level.
• Local climate, occupancy, and heating usage patterns.
• Electricity, gas, and oil tariffs, standing charges, and supplier changes.
• System design quality, emitter sizing, and installer recommendations.
• Maintenance standards and operational settings.

Changing prices, grants, and costs

• Energy prices can change at any time.
• Grant values, eligibility rules, and application processes can change.
• Installation costs vary by region, installer, system complexity, and building condition.

Professional survey required

Before making financing, installation, or equipment decisions, obtain a professional survey and written quote from qualified installers or advisors.

No guarantees and no professional advice

We do not guarantee suitability, savings, payback period, grant approval, or final system performance. Nothing on this site constitutes financial, legal, engineering, or installation advice.
