Heat is applied only at the ends of the balloon.

heat pumps which can only provide hot water for sanitary use

Heat transfer from the high-temperature thermal reactor to the shield carrying the thermoelectric units occurs only through thermal radiation; similarly, heat is lost by the shield only through radiation.

boilers generating heat exclusively for providing hot drinking or sanitary water

heat pumps which can only extract heat from a building and eject it to the air, ground or water thus resulting in space cooling.

The best indirectly heated boilers with heat exchanger only

Here is the average temperature (For reference Only)

This transfer paper is designed to be used in a heat press only.

The reaction mixture is only contacted with the heat sources long enough for the desired temperatures to be reached.

Operation area is extended to lower flow rates only in case the unit operates with heat pump only.

The peripheral layer (10) extends from the upstream end (4) of the heat source (2) only part way along the length of the heat source (2) and circumscribes an upstream portion (12) of the core (8).

The researchers found they could record information using only heat - a previously unimaginable scenario.
