Wilo Yonos Central Heating Pump 6m
Replacement for a failed pump
It's the usual story, you get up in the morning and the showers cold...
My first thought was the boiler had a failed control circuit card, it's 14 yrs old and I have been expecting it.
But as turned out it was only a failed circ pump, I nipped out to my local Screwfix branch and bought the Wilo Yonus to replace one of the older Wilo pumps.
As is the way these days electronics have crept in, I really can't see the point as far as I'm concerned it's just another lair to go wrong, why I need a digital display beats me, I can't even see the thing unless I remove a panel.
One thing that didn't seem totally clear was turning the pump body/display, for the record you do need to take out the four main cap screws and actually spin the motor housing round in some mounting positions, just don't pull it all the way out.
The electrical connection is now a fancy plug simple enough to wire with the spring latch terminals, again I suppose when this one fails it will be a simple task to plug into the new one provided you can still buy the same model in ten years time...and they haven't changed the design again.
Can't comment on the reliability yet as its only been less than a week, I find these pumps in my system last about 12yrs, then die on Xmas eve....

This is an excellent pump packed full of features, can be used in one of three settings or variable pressure to suit your needs. It is also extremely quiet a lot quieter than expected (more or less silent).

Great replacement pump
Ideal replacement for existing but burnt out pump, liked the electrical plug rather than having to rewire. Great Guarantee period.

Good quality pump
This pump was a replacement for a Wilo 60 which had given me good service for over 10 years.
The range of adjustment on the Wilo Yonos makes it a very flexible pump for many installations. In addition it is extremely quiet and power efficient.
