About HeatWise Home

What we do

HeatWise Home helps homeowners understand the numbers behind heating and home energy decisions. The site combines simple calculators with plain-English guides on heat pump running costs, system sizing, insulation upgrades, grants, and appliance electricity use.

Our aim is to make early research easier. We show the assumptions behind each estimate, explain the tradeoffs in everyday language, and encourage readers to compare results with actual bills, local quotes, and professional surveys.

How to use our information

The calculators are planning tools, not final design advice. Energy prices, grant rules, weather, installer design, building fabric, and household habits can all change the outcome. Before buying a heat pump or commissioning major work, homeowners should get a professional heat loss survey and written installer quote.

How the site is funded

HeatWise Home may earn revenue from display advertising, affiliate links, sponsorships, or referrals. We use disclosure blocks where relevant and do not present calculator outputs as guaranteed savings.
