I have a hot water tank in my shed that supplies heat to the house. When the water gets cool (thermostat) it kills the power to the pump on the outlet.

I am looking to turn on my oil boiler for a fixed time when this happens. i.e. when house requires heat, if water tank is cold, it uses oil boiler for an hour instead.
