Wilo Yonos Central Heating Pump 6m is rated 4.5 out of 5 by 45.
Rated 5 out of 5 by from Wilco Gold 50 replacement Bought this as replacement for a Wico Gold 50 , this was a direct replacement and fitted without any pipe work alterations. The first thing I noticed is that it is very quite and little vibration. Also when you look at the display the amount of power it uses is significantly lower than the old model. It also features a easy wire connection to the pump which just plus directly into the pump. So far an excellent purchase and great value for money.

Rated 5 out of 5 by from Great Pump I purchased this pump, as I could hear a slight noise coming from my own Wilo Pump, fitted 18yrs ago. That was on 3/1/17, lo & behold, on 10/2/17 the old pump finally gave up, no shame in that. I have retired now, due to arthritis & couldn't get into the small cupboard it is mounted in, but my son, 26yr old, with no plumbing experience, fitted it, under my guidance. Just needed to shorten the wires, for a neat fit into the screw-less terminals & away it went. Won't even have to rewire that, next time round. All dead simple. Great to see the difference in power usage, 7watt on hot water only, & 29watt on hot water & heating, with setting at 1. I have always used Wilo Pumps, throughout my 35yr career & found them very reliable. If this one lasts as long as the last one.................nuff said. ;-) A wee tip: Smear a little silicone grease on the threads, before fitting. Makes replacement a doddle. PS: I have given Reliability 5 stars, but that is based on previous Wilo Pumps. Couldn't possibly give a reliability rating on this one, as it is so new, so make your own mind up.

Rated 4 out of 5 by from Superb pump Central heating tank started leaking so replaced that and all that goes with it,, re-started the heating and the old Grundfos pump showed its age creating a loud clattering noise.. Went to Screwfix online to order a replacement, but noticed the smaller and cheaper Wilo range and after checking out all the specs decided that it might be a good choice. Fitting was simple, exactly the same connectors as the Grundos. Powered it up and selected self-venting (very useful to have a display on a pump - you get valuable feedback as to what it is doing)... after this the pump ran virtually silently! A really pleasant surprise - I would recommend this to anyone needing to replace a CH pump.

Rated 5 out of 5 by from Silent operation My old CH pump packed up, probably the cap as it normal is on pumps in my experience but at this time of year I could not afford the wait so I decided to replace the whole pump for speed. The pump was 2004 vintage so it had done 12 yrs. This pump is a lot smaller which shows how pumps have improved. And totally silent in operation, all you can feel is a slight vibration which says it is running. My old pump also had a problem with water surge as when the thermostat cut out it would stop instantly causing the water to surge up the overflow to the F&E tank. I'd had to raise the overflow pipe to stop that actually overflowing into the tank. This pump seems to have softer stop which means it is also quieter when it turns off than the old pump. It also useful to have the variable load as all but one of my radiators have TRVs. All in all an excellent pump! Too early to say about the reliability but it does have a 5yr warranty so the makers have confidence in it.

Rated 5 out of 5 by from East fit, quite, good pump. I've just replaced my old Wilo Gold 50 as after 15 years in service the bearings had become rumbly. I was unsure which pump to use as a replacement so a visit to the Wilo website gave pump dimensions from port to port. Great. electrical connection, easy and well designed. If you can replace a 3 pin plug you can fit this connection. Most impressive feature is the venting mode which runs for 10 minutes. Bleed my system a treat. Always read the manual, clear and straight forward for a non plumber. Recommended buy, never sure how we can review reliability? Will have to wait and see.
