When I replumbed the calorifier to the back boiler I installed two stop cocks to isolate the calorifer during the summer when the back boiler is not in use. This has worked fine so far, but as they are not at the most accessible place I have been looking out for a pair of 12v motorized valves. Recently I f0und some on eBay at £10.55 each plus postage. They come from China so took a few days to arrive.
They do require four 15mm – ½” couplers at £5.54 each plus postage from RS to convert the valves ½” female connection to 15mm push fit.
I installed them Friday after we took the engine room shelves out and before Jo started painting the engine. I have left the two stop cocks in as back-ups. This morning I wired them up.
The valves do require a double pole double throw toggle switch courtesy of Maplins at £2.79 plus postage to operate them.
These valves automatically shut off once the valve is either fully open or fully closed.
Once I completed this successfully, Jo then removed the engine room steps and painted them, then painted the day tank, and then painted the engine room floor.

Hi Keith, sorry to ask what I hope is a totally unnecessary question, but where/why have you fitted the valves?
Where and why I described is at the beginning of the post Kevin as follows:- "When I re-plumbed the calorifier to the back boiler I installed two stop cocks to isolate the calorifer during the summer when the back boiler is not in use.
