I've been reading about devices made by Tekmar and Beckett will either
of them do what I want? My boiler heats my hot water and these days I
hear it cycling all night just to keep the water hot enough in case I
decide I want to take a bath at 2am. Is there any way I can tell my
boiler to take 6 hours off at night while I'm sleeping?

Yes, probably. Assuming you have a domestic coil in your boiler, and not an
indirect hot water maker, you could rig a time clock to interrupt the
aquastat circuit , which is maintaining tank temperature. I doubt there
would be a huge savings though. If it comes on a few times during the night
and only runs for a minute or two, to keep the set temperature, it would
probably come on at the end of the timer cycle, in the morning, but have to
run for a longer period of time to make up for the greater reduced
temperature in the tank.
