There is a likelihood that underfloor heating may add to offgassing and sick building syndrome in an environment, particularly when the carpet is used as flooring. [citation needed] Electric underfloor heating systems cause low frequency magnetic fields (in the 50–60 Hz range), old 1-wire systems much more so than modern 2-wire systems.
The ASHRAE Underfloor Air Distribution Design Guide suggests that any building considering a raised floor for cable distribution should consider UFAD. [ 8 ] Specific space considerations should be taken when using UFAD systems in laboratories because of its critical room pressurization requirements and potential migration of chemicals into the ...
Hypocaust under the floor in a Roman villa in Vieux-la-Romaine, near Caen, France. A hypocaust (Latin: hypocaustum) is a system of central heating in a building that produces and circulates hot air below the floor of a room, and may also warm the walls with a series of pipes through which the hot air passes.
These first Heisler–Gröber charts were based upon the first term of the exact Fourier series solution for an infinite plane wall: (,) = = [ + ], [1]where T i is the initial uniform temperature of the slab, T ∞ is the constant environmental temperature imposed at the boundary, x is the location in the plane wall, λ is the root of λ * tan λ = Bi, and α is thermal diffusivity.
The lower temperatures and large surface area of underfloor heating systems make them ideal heat emitters for air source heat pumps, evenly and effectively radiating the heat energy from the system into rooms within a home. The maximum temperature of the heating surface can vary from 29–35 °C (84–95 °F) depending on the room type.
Pilae stacks are stacks of pilae tiles, square or round tiles, that were used in Roman times as an element of the underfloor heating system, [1] common in Roman bathhouses, called the hypocaust. The concept of the pilae stacks is that the floor is constructed at an elevated position, allowing air to freely circulate underneath and up, through ...
A ground source heat pump is used in winter to extract the warmth from the Thermal Bank to provide space heating via underfloor heating. A high Coefficient of performance is obtained because the heat pump starts with a warm temperature of 25 °C (77 °F) from the thermal store, instead of a cold temperature of 10 °C (50 °F) from the ground.

In the early medieval Alpine upland, a simpler central heating system where heat travelled through underfloor channels from the furnace room replaced the Roman hypocaust at some places. In Reichenau Abbey a network of interconnected underfloor channels heated the 300 m 2 large assembly room of the monks during the winter months.
