Volunteers wanted for trial of heat pump controls
Posted by Tasha Kosviner on 15 October 2013 at 11:17 am

Famous for flat-pack furniture and its clean, Scandinavian design, Ikea is a surprise entrant into the solar PV market. With 18 massive stores in the UK it's known for value for money household goods (some would say cheap) and jokes about Allen keys. So would you trust it to sell you solar pa…
