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.
