Swimming Pool Boiler FAQs
Can a standard commercial gas engineer repair my pool boiler?
Not necessarily. Swimming pool boilers are a niche appliance. To legally install, service, or repair them, an engineer must hold a specific HWB1 ACS certification. The SEM Facilities team is fully HWB1 accredited and registered with Gas Safe to work on these specialist systems.
Can you add my pool boiler to our existing SEM maintenance contract?
Yes. Integrating your swimming pool boiler into your existing planned preventative maintenance (PPM) schedule is the smartest way to manage your facility. It consolidates your contractors and ensures your leisure amenities receive the exact same high standard of care as your main plant room.
Why do swimming pool boilers require specialist maintenance?
Pool boilers operate in harsh, highly corrosive environments due to the presence of chlorine and other pool chemicals. Without regular, specialist servicing, the heat exchangers can rapidly corrode, leading to costly premature failures, poor energy efficiency, and unsafe gas conditions.
