As with all Archergas circulators, it is fully ERP compliant with an impressive energy efficiency index rating of less than 0.20. The PRO15 is suitable for radiators, underfloor heating, cooling, solar, recirculation (non-potable) and air source heat pump systems.Due to the quality focused approach to manufacturing and use of high end component materials, this circulator is resistant to condensation, corrosion, high pressure and high temperatures. It also comes with a 5 year guarantee and can be used as a direct replacement for a large number of other models, some of which are listed below:Make | Model - Replaces:Grundfos | UP, UPS 4m, 5m, 6m, UPSD, UPS2, UPM3 & UPS3 Lowara | Ecocirc, Ecocirc Basic & Premium 25-40 & 25-6 (130)Wilo | Yonos Pico 15/1-6-130, Gold, Gold Star, Gold 50, 60 & RS25 Embrass Peerless | Eclipse CFA 25-50 & 60-130DAB | VA55/130, VA65/130, Evotron 60/130, Evosta 40/70 Circulating Pumps | CP50, CP60 & Myson LA, SD, CP53 & CP63BritTherm | P1 25-6/130 & Domestic Pro 15-60/130Salus | MP100A & MP200 Boiler M8 | RS25/6G-130, RS25/6EAR-130, GPA25-6 II AC & GPD25-6S-130Stuart Turner | ST 15/60 (130) Antares | Type S40 to S60, Alfamax RS & AS 15/40 to RS & AS 25/60 (130)Pegler | Terrier TC5 & TC6Circulating Pumps (Myson) | CP50, CP60 & Myson LA, SD, CP53 & CP63Flomasta | 25-5-130 & 25-6-130Smiths | ES2 25-60/130IBO | OHI, BETA, MAGI & NOVA 25-60/130SMC | Cadet, Commodore & Comet 130Katsu | 151711Ferro | GPA 25-6 IIEuramo | MXL 130, D, Gold, Solid Gold, GoldstarArcus | 356R & 136EAJass Ferry | KBD20-6S-130 & KBD25-6S-130Primaflow | CP5, CP6, CPE6 & HE-6Tucson | GPD25-5S & RS256EACBS | CBS 60 & CBS Intel 15-60/130Adlink | Type 15-60/130 & 25-60/130Anchor Pumps | Desgee AC 15-130Bacoeng | DN40-6GTrident | WPB 25-6WSTN | WRS 25-60/130FHS | LPS40-6S/130Tower | APUMP+For more information visit www.archergas.com or download the Archergas app on iOS or Android.
