This is such a common question, we’ve designed software to allow us to quickly and accurately size both UFH and radiators to your property. One way to check if you need to replace your current radiators is to lower your fossil fuel boiler’s flow temperature down to 50°C for a week or two during winter. If you your property is still maintaining its target temperature, its more than likely there will be no need to upsize your radiators. Alternatively, speak to our team and we can simulate this for you anytime time of the year.
