Heatrae Sadia has launched Megaflo Eco Solar PV Ready, an unvented cylinder that heats water for free by harnessing excess electricity generated by domestic solar PV arrays.

It is estimated that 50 per cent of users are not consuming the power produced by their PV panels because properties are generally unoccupied during the daytime and electrical appliances and lighting are not being used during daylight hours when the electricity is generated.

The Megaflo Eco Solar PV Ready cylinder is designed to ensure any surplus electricity can be used to heat up water, free of charge, and thereby reduce utility bills. Any power generated in addition to the household’s normal requirements will be diverted to the cylinder, rather than being sent to the grid. The water is heated to the desired temperature, controlled by a thermostat, ready for the household to use when required, with high-performance insulation keeping the water hot.

To avoid any draw from the grid, a ‘buffer’ of energy will be retained; typically, if there is 2.2kW of export energy, the controller will divert 2kW into the cylinder’s immersion heater, leaving a 200kW buffer.

Megaflo Eco Solar PV Ready can be used in conjunction with any PV array, whether existing or new. Installing the cylinder is simple: the wiring is identical to the Megaflo Eco and, providing the installer has a G3 unvented qualification, no additional training is needed. A separate remote control – the Megaflo Buddy – enables the end user to control and modify settings, and displays the energy and savings being generated.

Megaflo Eco Solar PV Ready will not affect the property owner’s FIT Generation payments, as this is a ‘deemed’ usage contract that has an export tariff paid, whether the energy is consumed or not.

Where an export meter is fitted, the benefits of Megaflo Eco PV Ready can still outweigh the costs of heating water directly from the grid.
