Your CALYPSO questions answered

What is the maximum length of ducting that can be used with the Calypso?

There is no specific maximum ducting length.

The length of ducting is determined by the ducting design (number of elbows, etc.), type (circular, or letter-box style) and manufacturer.

Is the Calypso compatible with photovoltaics and off-peak tariffs?

The Calypso has an additional signal input to receive either an off-peak or PV signal.

When using an off-peak signal, this can be used to determine when and whether the immersion heater or heat pump are used.

When installed alongside Solar PV, the surplus energy produced by the PV system can be stored as hot water in the Calypso, practically free of charge.

Can I control my Calypso remotely?

The Calypso can be controlled remotely through the Atlantic Cozytouch App, in the same way as other Atlantic products – the Agilia, Oniris, ang Galapagos electric radiators.

A cozytouch bridge, which connects wirelessly to your Wi-Fi router, is required for connection (sold separately).

What size Calypso do I need?

You size the Calypso as you would with any direct electric hot water cylinder. The HWA recommends 45L per occupant per day. So a 172L could support a 3 occupant household.

Is this product manufactured in the UK?

The Duplex Stainless Steel cylinder is manufactured by Gledhill in the UK. The rest of the unit is assembled at the GA factory in La Roche-Sur-Yon in France.

Where can I buy the Calypso from?

The calypso will be sold through both electric wholesalers, as per the rest of the Atlantic range, as well as P & H merchants.
