Questions people ask

Do heat pumps need oversized radiators?+

They often need more emitter output than a high-temperature boiler system, but the requirement is calculated room by room. Not every radiator automatically needs replacement.

Can I keep my existing hot-water cylinder?+

Some cylinders may not have a suitable heat-exchanger area or recovery performance. The design should check this along with available space and household demand.

Will larger radiators change the appearance of every room?+

Selective replacement, alternative radiator formats and other emitter options can be considered as part of the design.
