The Haycock boiler produced and stored large volumes of very low-pressure steam. In principle, they were based on a ‘steam-kettle’ design where a heat source (usually a fire) heats a partially filled water container from underneath. The heat transfer efficiency of these types of boilers was generally very low.

Haycock and wagon top boilers. For the first Newcomen engine of 1712, the boiler was little more than large brewer's kettle installed beneath the power cylinder. Because the engine's power was derived from the vacuum produced by condensation of the steam, the requirement was for large volumes of steam at very low pressure hardly more than 1 psi (6.9 kPa) The whole boiler was set into brickwork
