Load compensation in boilers is a technique that adjusts the temperature of the central heating water based on the heat requirements of a building. This is achieved by using an internal sensor to measure the difference between the current room temperature and the desired temperature set by the user. The controller then communicates with the boiler to increase or decrease its output to precisely close the gap between the current and desired temperatures. This method of control

Improving Efficiency, Control, and Performance with a Correctly Sized System Boiler Replacing an outdated fireplace back boiler with a modern heating system can present several design challenges. One recent project involved relocating the boiler from a fireplace back boiler arrangement to a first-floor cupboard. Here, we installed a Viessmann Vitodens 100-W 19kW system boiler, designed around a Priority Domestic Hot Water (PDHW) setup. Our goal was not simply to replace the e

Traditional central heating systems, made up of a gas boiler and hot water cylinder connected using an S or Y plan configuration are set to run at one flow temperature. This usually is somewhere between 65°C - 75°C, meaning that the heat output supplied by this system is designed for both hot water and heating demands. However, running at such high temperatures can limit the potential efficiency of the boiler. A priority domestic hot water installation however separates the h
