Free hot water from PV array

The Megaflo Eco Solar PV Ready is an unvented cylinder that heats water for free; accomplished by an innovative design that harnesses surplus solar electricity to generate hot water, saving energy and reducing utility bills.

It's estimated over 850,000 in the UK have solar PV panels install but only 50% are consuming the power produced by their PV panels. The Megaflo Eco Solar PV Ready can be used in conjunction with any PV array, existing or new. Installation is simple and using a separate remote control - the Megaflo Buddy - enables the user to simply and easily control and modify settings. The Megaflo Eco Solar PV Ready is available in direct and indirect, in capacities ranging from 170 to 300 litres.

Heatrae Sadia have been shortlisted as a finalist in the Domestic Heating Product of the Year - boilers, cylinders, stoves and heat pumps category with the Megaflo Eco Solar PV Ready. Click here to read more about this prestigious H&V award.
