    Hi. :confused: i fitted a new timer/programmer to my gravity fed CH and HW system about 18 months ago, a TIARA the same as my old one. It is fitted via a fused spur, i also have a single plug fitted to this spur to charge our dyson. Just recently ,after having no hot water, we found that the clock on the timer was slowing down ,losing about 6 hrs a day. What could be causing this problem ? does the timer need renewing again ? could the spured plug to charge the dyson be causing the problem ? would appreciate any advice. Thanks

    Sorry, but you need a new timer. I've had exactly the same problem and bought a new timer which solved the problem. Whilst old electric clocks used mains frequency, modern timers use a chip with a fixed frequency so your dyson wouldn't have any effect. Look for a timer guaranteed to be accurate - there are several around and cheap because you only need a pump timer and not the complications of HW timing.

    Thanks for your reply . Could you recommend an easy to use timer for both CH and HW. Dont want an over the top digital timer , have one fitted for underfloor heating in the kitchen ,and its an absolute nightmare . Thanks.
