Reply #4 - Oct 23^rd, 2006, 7:49pm Most likely problem is the divertor valve, try sliding the lever across and hooking it in manual.

Decided that the cost of diverter valve is throwing good money on an old horse. Right...... change of direction, best cond. combi on the market? Live in semi detached house, 1 bathroom and 10 rads. From what I have read, 28i junior or 30CDI Worcester Boilers are the best around for what I require. Would you agree????????

Reply #6 - Oct 23^rd, 2006, 11:46pm The only small boiler I would consider is the Boulter. I personally don't think any of the lower end market are that reliable and everyone has they're favorites http://www.boulter-buderus.co.uk/site.home/203/m_id/204
