Good quality pump for the price, easy install and very quiet
Used these pumps before infinatly adjustable good for heating and underfloor applications easy fit and set up
Easy to install, straight swap out. Definitely download the manual using the QR code in the leaflet to understand the drawings in the box. Comes with replacement washers too.
Good price super quiet and speed dial completely adjustable
Works great, good value, does the job, cheaper than the market leader doesn’t the same job
Quiet, efficient and easy to fit but will it last the 32yrs that the old one did? It does use a quarter of the power though if the screen is correct.
Good quality pump at a reasonable price, deliver is very good too 👍
Really happy works as it should easy to fit quieter than 40 year old pump it replaced
Great pump, so quiet and low energy consumption - also great feature to purge air out of the system
Good quality pump and easy to set up , seem reliable
I fitted the pump for a customer.No problem since I've fitted similar one recently and found better instructions via download.(Booklet included is pretty useless.)I just wish there was a simple 3 speed pump without the clever electronics available.
Great quality pump from Wilo, competitively priced at Toolstation
Very easy product to install. Plenty of information on the internet about this pump and installation.
Excellent replacement pump with easy to use energy saving controls but not cheap!
This was easy to fit. It's very quiet in operation and appears to be sturdily built.
Installed this make and model several times before on various central heating systems. Working in the plumbing and heating sector. A reliable pump, easy to calibrate and works well on new and existing systems
It is a powerful and compact pump, with a very good information display, but the design makes installation very awkward.
The flimsy plastic control unit is very tall making it difficult to get a wrench onto the top nut.
I ended up removing the rotor cove/control unit to tighten the nut.
The manual is pretty terrible, the electrical connector pictures are especially bad.
It does not specify that revealing a hole to insert the wires into requires the flimsy plastic levers to be pushed beyond 90 degress, it took me 20 minutes of fiddling to realise that.
Fitting straight forward as was a direct swap for old pump - good straight forward easy wiring - downside rubber washers leak - use fibre washers to avoid leaking on initial fit
easy to fit good wiring option nice and quiet
