Why Earn The Low Temperature Heating Design Qualification?
Low-Temperature Heating Systems are classified as systems in which the hot water leaving the generator doesn’t normally exceed 55°C. Heating properties at a more constant pace, low-temp heating is an eco-friendly option when compared to a regular gas boiler central heating system.
The Low-Temperature Heating Design course is designed to allow engineers to upskill in the concept of low-temperature heating systems. The aim is to demonstrate their knowledge and understanding of the need and requirements of installing low-temperature heating and hot water systems in domestic dwellings.
Assessment takes place through e-assessment and design scenarios.
