The science behind the trade — pressure and head, heat and expansion, flow and units.
Heat & Hot Water
Heating it and storing it safely — hot water and central heating systems.
Premium
Level 2Hot Water Systems
Vented and unvented hot water, safe delivery temperatures, expansion and secondary circulation.
Free
Level 2Central Heating
System layouts, controls and interlock, emitters and balancing for domestic heating.
Water Out
Taking water away — drainage, sanitation and rainwater.
