Abstract: A heating apparatus has a catalytic burner and a thermal receiver which consumes at least one portion of the heat generated by the catalytic burner. The catalytic burner has a member for ejecting a flow of combustible gas, a member for admixing primary air with the flow of combustible gas to obtain a mixture to be burnt, a chamber for distributing the mixture, and a catalytic combustion structure in communication with the distribution chamber. The combustible gas travels into an upstream face of the catalytic combustion structure, and combustion exhaust gases are removed through a downstream face of the catalytic combustion structure. A radiating flameless combustion front is located in the vicinity of the upstream face of the catalytic combustion structure during operation. A thermal receiver extends along virtually the entire surface of the upstream face of the catalytic structure and receives thermal energy.
