Nov 15, 2019 · If the system were to have a thermostat with weather compensation fitted, this works by reducing the flow temperature of the boiler so matching the output of the radiators, proportionately, to the temperature difference between inside and outside. Most systems are designed around a difference of about 22*C, i.e. -1*C outside temperature.Get Price
The difference will be most noticeable when you first fire the boiler up. The flow will be extremely hot (within a matter of minutes), but the return will be cold or Luke-warm. As the entire heating system comes up to temperature (i.e. your radiators start getting hot), the difference in temperature between the two will begin equalising.Get Price
What is a Boiler? Boiler Definition . Boilers are defined as "Boiler is a closed vessel in which water or other liquid is heated, steam or vapor is generated, steam is super-heated, or any combination thereof, under pressure or vacuum, for use external to itself, by the direct application of energy from the combustion of fuels, from electricity or nuclear energy.Get Price

Pressure reducing valve A is reducing pressure between the boiler header and the distribution main in the plant, responding to the pressure sensed in the 5 bar line. If the steam demand should exceed the capacity of this supply from the boiler, and the pressure in the low pressure main falls below, for example 4.8 bar, valve B will begin to Get Price
Heat transfer usually takes place from high temperature to low temperature. In the case of Boilers, flue gases or exhaust from the boiler outlet are at high temperature and water that needs to be preheated is at low temperature. So, this temperature difference between water and flue gases helps to increase the feed water temperature.Get Price
