Heatstar has a new climate control unit
on the market which follows on from the
specialist company’s success of the Gemini
combined heatpump-dehumidifier.
The Andromeda EC30 utilises the low
energy fan technology which, previously,
was only available to the pool industry
within Heatstar’s Gemini concept, and is
designed specifically for domestic pools
with surface pool covers.
