Ask the Expert, Jonathan Hancock, Product Manager - NIBE
After 10 years, the Building Regulations have changed! It’s important that we all understand what this means for heating installations in new and existing homes. With the introduction of the updated Conservation of Fuel and Power Part L Standard on the 15th of June 2022, all new homes must produce less CO2 emissions and some of the changes will extend to existing buildings too.
This uplift will ease in heat pump specifications for zero carbon ready buildings by ensuring that homes built today either have heat pumps installed or are future proofed to easily adopt them in the coming years. The regulations tackle performance through assessing the primary energy demand, carbon intensity and fabric energy efficiency standard of the building.
Key Changes for Heating Engineers
To pave the way for heat pumps, the Regulations now state that 55oC is the maximum flow temperature for all new and replacement heating systems as they operate at lower flow temperatures compared to traditional heating systems. This will not only lower running costs for customers through optimising heating appliance efficiency but will also minimise damage to the pipework through reducing corrosion. A win-win for everyone, even those with gas boilers.
It’s worth bearing in mind that this might mean that you’ll need to consider replacing radiators. But it will make it cheaper to install a heat pump in the future if you’re not doing so today.
In addition to the lower flow temperatures, new or replaced heating systems must be combined with thermostatic room control in each room. This requirement is applicable to all heating systems including heat pumps. In certain circumstances this can be achieved via heat zoning, such as in open plan dwellings where the living area is more than 70% of the total dwelling floor area. For properties with over 150m2 floor area, a minimum of two independently controlled heating circuits are also needed. This will provide your customers with better control and enhance indoor comfort.
How our suite of products help you comply
Whilst these requirements are new, we have been working hard to prepare for this change and NIBE has a range of products that can support compliance whilst delivering a great user experience. For example, NIBE’s smart home accessories allow customers to sit back and relax while their heating system automatically adjusts the temperature, humidity and CO2 level inside their home – or they can adjust them manually through the myUplink app to suit their needs. Our smart controls have been designed with our heat pumps and customers at the centre which mean they integrate seamlessly into any installation.
Our SRV 10 wireless radiator thermostats allow customers to obtain a comfortable indoor temperature whilst reducing energy consumption by only heating rooms when needed. Being battery powered, it is easy to install too. By adding these to a system, you’ll also meet the new requirement for thermostatic room control in each room. The wireless radiator thermostat has a M30x1.5 connection and a Danfoss RA adapter is included so that it fits most heating systems. The SRV works with all our NIBE S-Series heat pumps providing even more precise control.
Our whole suite of accessories, including electronic, temperature and smart controls are easy to install and can help you achieve compliance by creating room or climate zones throughout the home without the need for third party products. With NIBE its easy to be smart! So, why not work with us?
