Heat load surveys and system design across County Antrim
No two rooms in Belfast gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. For self-builds and extensions in Belfast, a standalone design pack can go straight to your builder. In Northern Ireland, cooling is mostly needed in conservatories and glazed rooms, while efficient heating benefits the whole home.
