    Suggested Water Pump and Water Heater?

    Can anyone recommend a good pump and water heater to go with a Jobo processor?

    Sorry, I should have included this with my last thread about the Jobo CPE2.

    Your CPE-2 should have a pump and heater built into it? What are you asking?

    Andrew looks like he's up against the limited capacity of the Jobo for tempering enough water for washing and preheating enough chemistry for a long session. I've seen the prices on the Jobo TBE, and had problems with spending that much on a plastic tub and heating element.

    Given that, for an auxiliary tempering bath I use an aquarium pump and a submersible heater with thermostat, DevTec Model TC-750 made for photography by Doran Enterprises, www.doranet.com, and available from B&H Photovideo and others (http://tinyurl.com/6tjfk). I put them in a shallow plastic storage box with closed cell foam on the bottom and sides. You could also use an ice chest/cooler/eski for a bit more efficiency. I know some people use aquarium heaters, and they could be less expensive, but I went with the US$110 purpose built unit because it's designed to withstand exposure to photochemicals. This arrangement certainly helps when the Jobo capacity isn't enough for wash water, and holds temperature to a fraction of a degree very well. Perhaps there's something similar in the UK market, or an aquarium heater would serve. I suspect the 750W DevTec might have a larger heating capacity than small aquarium heaters. It is designed to work with color processing temperatures, although I've only used it at 75F and lower.

    Sorry, but I don't know if this is distributed in the UK. It certainly looks like it's still made in the US.

    If that's the issue.

    My tempering box is a picnic cooler,aquarium pump and 350watt heater. The pump is a nice extra you can live without. Just stir every so often until you reach the target temp. Works great.

    If you're only looking to temper some wash water then all you really need is the picnic cooler. Fill it with warm/hot tap water at a temp higher then you need. The cold cooler will bring the temp down to the temp you need. It'll take a bit of testing to figure out how much. The water in the closed cooler will hold it's temp for quite a while. All the heater in mine does is deal with the fact I'm opening closing the lid every so often. Once the temp is at the right temp the heater runs very little.

    Thanks for the advice guys. As it is there's a huge pet store down the road from me and I'll check into their aquarium pumps.

    I know this is very late, but empty a portion of the water and refill with hot tap water to bring the temp up to a few degrees of desired. Then let the machine the last few degrees.

    Chemicals can be heated fast in a deep tray with 120 degree water.
