Posted elsewhere is a simple method of using a thermos. You need an accurate thermometer too.
Get the water to the temp you want in the thermos and put the seeds in for the desired length of time. I can confirm that over the 25 min it will lose maybe 1 degree.
There are tons of papers that describe surface sterilization of tomato seeds with bleach.

The pyrex + hot kettle appears straightforward and relatively easy to set up in any kitchen. Thanks for the link to the senior gardening hot water treatment.
