For every three 600/800 boilers installed and registered between 1st September and 30th November 2020.
ErP help and adviceThe Energy-related Products (ErP) Directive brought a number of changes to the way businesses operate within the heating industry. Our help and advice section covers everything you need to know.
There is also a duty on the householder to comply with Building Regulations please refer to the previous question for further guidance.
Because the method of calculation for boiler efficiency is different for all three ratings.
Our product training courses include an overview of the changes to the Building Regulations and what is required to comply. We will also provide information on our websites.
Flue Gas Heat Recovery (FGHR) is an energy efficient device that recycles the heat from the flue gases which would normally be expelled into the atmosphere and uses it to preheat domestic hot water.
Weather compensation is a device that communicates between the boiler and an outside temperature sensor. It tells the boiler to alter the flow temperature in relation to the weather outside, leading to fuel saving and a consistent environment.
Load compensation works by measuring the response of the heating system and controlling the flow temperature depending on the required load. When the boiler first fires, the increase in the return temperature is measured, giving an indication of the required load, and the boiler varies the flow temperature accordingly. The changes in the return temperature are then monitored and the flow temperature adjusted accordingly. This can reduce fuel consumption.
