Only thing is the warranty but at £365 saving its worth the risk. Plumber came yesterday and did all the vent work, and most of the water line rough-in. So a significant price difference on my quotes, equivalent spec and arguably better pipe. Removing the pipe rails this makes Wunda £365 more expensive, not including my smaller pumpset up upstairs. PSW came in at £1097 delivered for my system, this included 140 lengths of self adhesive rails. PSW and Wunda quoted for Grundfos pumps, UPM3 and EuP, unsure if any different.
My quotes from both for comparison give very different numbers. So for a 300m 3 port setup, with 300m of pipe, total cost like for like (Wilo) is PSW £449, Wunda £463Īnd that doesn't include delivery which makes them basically the same price. PSW Pex-Al-Pex is £54 per 100m, Wunda Pert-Al-Pert is £63. PSW comes with a 1 year warranty, Wunda comes with 5 years. After importing the autocad layout of my house and carefully inputting all the relevant information to calculate heat loss etc I find myself in the circuit layout settings, with 2 options. Any ideas and suggestions are appreciated. I am using the trial version of LoopCAD 2020 Watts edition. PSW vs Wunda is £208 vs £274, that is for an IBO pump on the PSW and a Wilo on the Wunda.Ĭheapest Wilo Yonos pump I can buy today is £79, so that makes the PSW set up £287, vs £274 for the Wunda. Looking for some reasonably-priced, simple to use, but good design software for radiant design, loop layout, heat-loss calculations, etc. Other add-ins are available free of charge or can be purchased from a third-party vendor.
