I've got a combi boiler which heats the hot water tank using the indirect method. I use Hive to control it.
I'm trying to work out: if the hot water is set to on for an hour, will the boiler constantly heat the hot water tank for the entire hour, or will it detect when the water is hot and then turn off? and in like manner, if it is set to come on, and the tank is sufficiently hot from a previous slot in the schedule, will it still try and heat the tank?
Just trying to work out the best schedule and can't find an answer to this anywhere...
From a comment by the OP:
I'm trying to set up an efficient Hive hot water schedule, to give me hot water when I need it. In Hive hot water settings you can set to on/off only, believe temp control is managed by the tank... (don't have the models of tank / boiler to hand). So I wanted to know if I set the Hive schedule to On several times a day, whether it would burn gas still even if the water is already hot. I was guessing there's a temp cutoff, but wanted confirmation as I couldn't find any useful info about it elsewhere.
