Rated 3 out of 5 by Smart Pump Use plenty of these units and so far bullet proof. Value varies on here depending on offers and problems with staff not applying discounts correctly, recently have had to walk out as being quoted wrong costs. Screwfix lost the business by playing games! 13 Jan 2016
Rated 5 out of 5 by Wilco Yonos Pump for Christmas Bought to replace the old 18 year old Wilo Gold pump which had become inefficient and very noisy. Chose this unit primarily due to price and customer feedback. Excellent buy! Direct replacement and easy wiring. Lovely and quiet and system flow is good. Lets hope it lasts as long as the previous pump, ever hopeful. 4 Jan 2016
Rated 5 out of 5 by Great replacement pump Our CH pump started to give trouble on xmas eve. A quick look and I knew we needed a new pump. Used the Screwfix Click & Collect and picked the pump up the day after. at the local store in Bangor. Easy and painless as was the fitting of the pump. Heats on, wife's happy, the cats are happy so, I am happy. The pump has a modern electronic control ie variable speed/constant head/constant volume, selectiable via a control knob. A two digit numeric led display gives the head and wattage. The control box sits out from the pump so should run cooler and hopefully last. Easy. 1 Jan 2016
Rated 5 out of 5 by Wilo pump Our pump failed and I ordered this online. Collected within an hour and fitted. Easy job to do and very happy with its performance. Excellent value for money and customer service from the Rochdale branch :) 24 Nov 2015
