If i want to use it that way?** A: The question of hot water vs cold water pumps is a question about motor cooling. As a general idea, all hot water pumps can pump cold water regardless of manufacturer. This doesn’t hold for cryogenics though. TLDR - yes you can. **Q: how is it on electrical consumption?** A: The info that came with it says 46 watts at the lowest (of 3) speed settings which is what I use. That's 81 kWh per year, pretty small. the highest speed setting uses 93 watts. I don't notice it on my electric bill but then I have a 3200 SF house (4 bdrm colonial) with air condition in the Northeast. It works great. I used to have cold water and have to wait 1 minute wide open running time to get hot water; now it's instantly warm and hot within 20 seconds. Also, you can put it on a time (or buy one with the timer installed) but I get up often in the middle of the night and like instant warm/hot water. **Q: Are there instructions /operating manual available written in English?** A: Nope! It is cartoon drawn images for instructions. Not much to it. ## Frequently Bought Together - KOLERFLO 3/4 Inch Hot Water Circulating Pump 3-Speed Circulation Water Pump for Solar Heater System(RS15-6 Red) - Leviton 2321 20 Amp, 250 Volt, NEMA L6-20P, 2P, 3W, Locking Plug, Industrial Grade, Grounding - Black-White - Leviton 2320 20 Amp, 250 Volt, Flush Mounting Locking Receptacle, Grounding, Industrial Grade, V-0-MAX, pack of 1, Black --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/79632017-3-4-inch-hot-water-circulating-pump-3-speed-circulation](https://www.desertcart.no/products/79632017-3-4-inch-hot-water-circulating-pump-3-speed-circulation) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-10-12*
