Case Study: All-Electric Heating Upgrade in Coleshill, Birmingham

Project Overview: In late 2023, our team at M4RT was commissioned to undertake a full heating system upgrade at a residential property in Coleshill, Birmingham. The client’s objective was to remove their existing gas combi boiler and transition to a modern, fully electric heating solution. With solar PV already installed on the roof, they aimed to make the most of off-peak electricity tariffs, increase energy efficiency, and achieve complete room-by-room heating control for comfort and savings.

Client Brief:

• Remove and decommission existing gas combi boiler.

• Install a fully electric heating and hot water system.

• Maximise use of solar PV and off-peak electricity.

• Implement zoned heating in every room.

• Replace all existing radiators with modern, high-efficiency models.

  
  
  
  

  

Solution Implemented:

To meet the brief, we designed and installed a high-performance, future-proof heating and hot water system combining:

1. Tepeo ZEB (Zero Emission Boiler):

   • Acts as a thermal battery, charging during off-peak hours and providing space heating throughout the day.

   • Perfectly suited for time-of-use tariffs and works seamlessly with solar PV input.

2. Mixergy Smart Hot Water Cylinder:

   • Learns usage patterns to heat only what’s needed, saving energy and money.

   • Prioritises solar PV usage and can be controlled remotely via app.

3. MyEnergi Eddi Power Diverter:

   • Diverts surplus solar electricity to the Mixergy cylinder for water heating.

   • Maximises on-site renewable energy use and reduces grid dependency.

4. Room-by-Room Smart Zoning:

   • Every room fitted with a smart thermostat and TMV (thermostatic motorised valve), allowing independent control and scheduling.

   • Improves comfort and significantly reduces energy waste.

5. New Radiator Installation:

   • All old radiators removed and replaced with modern, efficient models matched to the heat profile of each room.

   • Ensures optimal heat distribution for the new low-carbon system.

   
   

Outcome:

The customer now enjoys:

• A 100% electric heating and hot water system powered by a combination of grid and solar energy.

• Smart, zoned control of every room for personalised comfort and improved efficiency.

• Lower carbon emissions and reduced reliance on gas.

• Increased savings through intelligent use of off-peak tariffs and solar PV.

  
  

This project demonstrates how the integration of advanced electric technologies like the Tepeo ZEB and Mixergy cylinder can deliver a highly efficient, sustainable alternative to traditional gas systems—without compromising comfort.
