Demonstrations into how 'ecopods', placed on the top of tower blocks as part a multi-million pound energy saving scheme, work will take place.

The seven tonne cannisters  use solar power to heat water along with the gas boilers inside and should in the long-term  reduce bills for tennats of the six blocks on the Ochard estate in Woodford Green.

The council will be able to monitor invidual usage from an inbuilt computer system, enabling residents to only pay for the heating and water they use.

Tennants and residents from across Redbridge are invited to take a look at how the 'ecopods' work at demonstrations on the estate on January 28 from midday to 5pm, January 29 from 9am to 5pm and January 30 from 9am to 5pm.

Staff from Belfry, the company behind the 'ecopods' will be on hand to answer any questions.

The council secured a grant of £10million for the work, which is due to be completed by April next year.
