Upgrading an AC immersion heater to 48V DC

Most thermostats made for AC will not be reliable with DC, as the points can arc with each opening, causing all sorts of problems, including welding the points together. Generally you can swap out elements if the threads fit. I have considered this but I would get a simple temperature control that could switch a DC relay or build a relay driver circuit for the standard thermostat.
