Overview
We recently tackled a job involving a problematic Heatmiser underfloor heating setup. This case came to our attention after the homeowners watched one of our YouTube videos on Heatmiser explainers. They reached out to us for help in sorting out their underfloor heating system, which had been causing them quite a bit of trouble.
The Situation: A Terrible Heatmiser Installation
The property in question is quite large, with underfloor heating installed on the ground floor. The challenge was that all the underfloor heating loops converged back to a cupboard, where two manifolds were located. Each manifold was equipped with a Heatmiser Hub UH8, designed to control the heating zones efficiently. However, the initial installation had left much to be desired. So, we had to go about fixing the Heatmise Underfloor Heating.
First, there was the issue of labelling. The manifolds weren’t labelled correctly, making it difficult to determine which loops connected to which manifold. This meant we had to decipher the loops on the diagram and ensure they corresponded to the right place on the manifold.
The plumber responsible for part of the installation had also provided several wireless neostat Heatmiser room thermostats. These needed to be paired with the UH8 RF wiring centre. However, the plumber had made assumptions about using a single thermostat to control multiple loops, which wasn’t optimal for achieving consistent heating throughout the property. Consequently, we had to add more thermostats to separate and control the heating loops effectively.
Fixing Heatmiser Underfloor Heating
My colleague, Paul, took on the task of organizing and fixing the underfloor heating system. He restructured the wiring and labeled the loops correctly, making it easier to identify and control each zone. This step was crucial to ensure that each area of the house received the desired level of warmth.
Additionally, we mounted the thermostats throughout the house to improve control and efficiency. This level of precision ensured that no area was left too hot or too cold, as can sometimes happen with underfloor heating systems.
Fixing Other Electrical Problems we Found
While working on the heating system, we uncovered several other electrical issues in the property that needed immediate attention. These included:
- Loose Breakers:Â The breakers on the three-phase board were loose, which could have resulted in unsafe conditions.
- Inadequate Isolators:Â The isolators used for the electric water heaters were not appropriately rated for the load they needed to handle. This posed a potential safety hazard.
- Incorrect Cable Types: The supply cables between isolators and boilers did not meet the manufacturer’s recommendations for heat resistance, which could have led to cable damage or fire.
- Poor Mounting of Boilers:Â The boilers were not securely mounted to the wall, which needed immediate correction to ensure safety.
- Exposed Live Sockets:Â Live sockets without enclosures and clear access to live terminals were found, presenting a significant risk to anyone in the vicinity.
Heatmiser Underfloor Heating Systems
We’ve done a lot of installs of the Heatmiser underfloor heating system. They are a really effective system and are known for their:
Efficiency: Heatmiser systems distribute heat evenly across the floor, ensuring that your living spaces are heated consistently. This method of radiant heating is energy-efficient and can reduce heating costs compared to traditional heating methods.
Comfort: Underfloor heating provides a luxurious and comfortable heating experience. It eliminates cold spots and drafts commonly associated with conventional heating systems, offering a cozy warmth throughout the room.
Space-Saving: Since underfloor heating is hidden beneath the floor, it doesn’t require radiators or wall-mounted heaters, freeing up valuable wall and floor space in your home.
Even Heating: Heatmiser systems allow for zoning, meaning you can control different areas or rooms separately. This flexibility ensures that you only heat the areas you need, further improving energy efficiency.
Potential Issues
However, like any heating system, Heatmiser underfloor heating installations can encounter common problems:
1. Incorrect Installation: One of the primary issues is improper installation. This includes errors in laying the heating cables or pipes, inadequate insulation, and poor zoning, leading to uneven heating or inefficient operation.
2. Compatibility Issues: Using incompatible thermostats, controls, or wiring can result in difficulties in setting up and controlling the system effectively.
3. Poor Insulation: Inadequate insulation beneath the floor can lead to heat loss, reducing the system’s overall efficiency and increasing energy bills.
4. Balancing Zones: Zoning can be a blessing or a curse. If not correctly balanced, some areas may become too warm, while others stay too cold. Achieving the right balance is crucial.
5. Electrical Problems: Electrical issues, like those we encountered in the blog, can arise if not addressed during installation, potentially posing safety hazards.
To enjoy the full benefits of Heatmiser underfloor heating, it’s essential to have the system professionally installed by experienced technicians who can navigate potential challenges and ensure it operates efficiently and safely.
The Importance of Proper Electrical Work
In the end, we managed to resolve the issues with the underfloor heating system, ensuring it functioned correctly and efficiently. This project also highlighted the importance of having qualified professionals handle electrical installations, especially when dealing with complex systems like underfloor heating and three-phase electrical systems.
