Reducing Energy Consumption in a Large Home: A Step-by-Step Guide

#vaillant #PDHW #costofliving In this video, I show you how I convert a highly inefficient and oversized gas boiler system into what is called a weather-compensated Domestic Hot Water Priority system and save the owners of this house an absolute fortune in their heating bills. This job involved: heat loss calculations (18.50kW) and new system design removal of one 24kW system boiler (not needed!) removal of one of 300L unvented cylinders (not needed, unless there is 15 of you!) rewiring of the system supply and installation of weather compensated controls - Vaillant Senso Comfort integration of existing controls (12 zones) into Vaillant Senso Comfort set up removal of low loss header and system pump (not needed!) improvements to hot water performance All those changes should save this family up to 40% on their energy use.
