Based on the experimental study on the equal spacing and two-pass style system with PP-B pipes, obtains the curves reflecting the relation between the heat release, water flow rate and water supply temperature, and finds that the larger water flow rate is, the less variation of heat release with mean water flow velocity in the pipes is. Through the thermodynamic properties comparison with those of traditional column radiators and experimental data fitting, provides the calculation formula of the heat release with an applying range that water supply temperature is 30~60 ℃ and water flow rate is 0.03~0.60 cubic metre per hour, verifying validity of the formula.
