How to master zoned heating systems
With energy prices staying high this winter, many homeowners are seeking more efficient ways of keeping their home warm so they can stay comfortable while spending less. Enter: zoned heating systems. Discover why you should be recommending this system to your cost-conscious customers and how to install them to ensure maximum effectiveness.
Why Should You Recommend Zoned Heating Systems?
Zoned heating systems are a straightforward way to make your home more energy-efficient. Rather than heating the entire house to the same temperature, zoning lets you target specific rooms or areas where heating is needed most. For instance, if you spend evenings downstairs, you can choose to only heat your living room and kitchen, leaving the unoccupied upstairs unheated.
It’s an advanced version of heating individual rooms, made possible by smart heating systems which allow for more flexibility and bespoke temperatures for each zone.
Using less energy is the main benefit of this system, which – according to industry estimates – can cut bills by as much as 30%. Less demand means less strain on the boiler too, increasing its lifespan and reducing the frequency of maintenance and repairs. Zoned systems also help with comfort, allowing you to keep bedrooms cooler while maintaining warmth in the family areas and meeting individual’s different preferences for temperature.
Key components: Radiators, TRVs & zone valves
Radiators, thermostatic radiator valves (TRVs) and zone valves are the core elements that work together to create an effective zoning system.
It’s worth investing in quality radiators which heat up faster and distribute warmth more effectively, especially when paired with modern boilers. TRVs are a must as they allow for more precise control over water flow in individual rooms. The zone valves control the flow of water to different parts of your heating system, effectively dividing your home into zones rather than rooms.
When installing these components, be sure to have a qualified heating engineer to assess your system’s compatibility and needs and assist with programming to avoid potential issues later on.
Staying compliant with UK building regulations
Ensuring your installation complies with UK building regulations is crucial, for safety and smooth system operation and to avoid expensive adjustments or costly fines. Always consult the latest building regulations before starting and work with an accredited installer.
In 2022, the government released the UK Building Regulations Part L, regarding the conservation of fuel and power in line with the government’s target of net zero carbon emissions by 2050. Zoning is now mandatory in new builds over 150m2, and advanced controls like TRVs are required in all new homes to help ensure the maximum flow temperature of 55°C.
Practical Tips for Installing Zoned Systems
Installing a zoned heating system can be a straightforward process, but it requires careful planning. Start by assessing the property layout and speak to your client for help defining zones based on which areas they use most often and their preferred configurations. You can then select appropriate components for each area, with more powerful radiators in larger spaces for efficient heating.
You may be able to retrofit it with zoned controls without the need for a full system replacement, but discuss the pros and cons with your client, including cost. Adding TRVs to radiators and installing zone valves in the pipework are relatively simple tasks that can be done without major disruption to the home.
Remember to set up a smart thermostat for each zone, enabling temperature control and remote programming access.
