Delay of boiler firing?

That's thermostat calling for heat hours, not boiler firing time.

Also it's a bit less as I have a 10 minute delay between the thermostat and boiler.

The thermostat duty rate setting isn't right and Honeywell was of no help with fixing it. So it'd call for heat and a few mins later be satisfied, and constantly do that.

10 min delay means the boiler won't fire unless the t stat has called for heat for at least 10 mins... ie, heat is truly needed.

I can't edit but I meant to say boiler won't fire and pumps won't run.

Once you get back to your equipment location, we can get down to the specifics. That is when you can get all the information needed. I believe that @hot_rod will have joined by then. I think that this will be a HX that will work for you. B&G BP400-20LP should do a modest size radiant floor system. It will handle whatever the 80K boiler can do. Your Oil heater needs to have the capacity, And I believe it is at least that big or more!
