Abstract: A recreational vehicle heating system comprises: a heating medium heater, a hot water supply heat exchanger, a heating medium circuit including a pump and a waste heat exchanger, and a heating medium tank compartmented by vertical partitions configured to allow for the heating medium flow over the partitions from one compartment to another in a sequential order, the hot water supply heat exchanger being arranged in one of the tank compartments, while the other tank compartments are part of heating medium circuits each including a pump and a waste heat exchanger. The first tank compartment in said sequential order is connected, via a conduit, to the heating medium heater, while the last tank compartment in said sequential order is configured to allow for the heating medium flow over to the conduit for the heating medium transfer by a pump via the heater to the first compartment.

Abstract: A food cooking stove, comprising a burner, a stovetop and a casing divided by a partition into a liquid transfer medium compartment and a combustion product compartment arranged under the stovetop and above the heat transfer medium compartment. The casing has provided in it a duct extending inside the heat transfer medium compartment through a partition between the compartments and the heat transfer medium compartment outer wall. The burner is coupled to a pipe arranged in the duct with a clearance to the duct walls and extending into the combustion product compartment. Combustion products are withdrawn from the compartment under the stovetop via a pipe extending inside the heat transfer medium compartment and tapped into the partition between the compartments and the wall of the heat transfer medium compartment.
