Could be a big year for Energetix, with the roll out of its combined heat and power (microCHP) boilers across the North-West of the UK. The £42.9million cap's flow trading brand will temp customers by offering a free microCHP boiler if they sign a five year dual-fuel contract. With 1.5 million boilers replaced each year, this is a compelling pitch to cash-strapped Brits given the £1000 -plus cost of buying a new unit and promised savings of up to £220 a yearv on current energy bills. The Chester company sees 15,000 by the end of 2013, rising to 90,000 in 2014 and around 200,000 by the end of 2015. Shares could hit 50p in the next twelve months.
