Booster System Continuity at Thermae Bath Spa
Background
Following plant room flooding during routine maintenance, the installed booster system required urgent intervention to prevent operational disruption. With the spa operating at continuous demand and water pressure stability critical to service delivery, a rapid and technically aligned solution was required.
Thermae Bath Spa is one of the UK’s most recognised thermal spa facilities, using mineral-rich waters from the King’s Spring, the Hetling Spring and the Cross Spring. Maintaining seamless operation was essential to protect both visitor experience and operational continuity.
The spa is also a recognised member of the Green Tourism Scheme, with environmental performance embedded across its operations. Preserving the efficiency of the existing variable speed booster system was therefore a key consideration.
The solution therefore needed to balance urgency with long-term performance integrity.
Design Requirements
- Restore full booster functionality urgently
- Maintain continuous water pressure
- Avoid disruption to public spa operations
- Integrate seamlessly with the existing Aquaboost MAB SP2V unit
- Preserve energy-efficient operation
Key Engineering Challenges
- Flooding impact within a live plant room
- Time-critical replacement requirement
- Coordinating supply and installation within a compressed timeframe
- Protecting system continuity during component replacement
The Solution
System Selection and Replacement Strategy
The existing installation was an Aquaboost MAB SP2V variable speed booster set originally installed in 2021. Following the flooding event, three replacement pumps and associated panel components were supplied to restore full system functionality.
Retaining the MAB SP2V variable speed configuration preserved key operational and environmental benefits by modulating pump speed in response to demand. This delivers:
- Reduced electricity consumption
- Lower overall carbon footprint
- Reduced operational noise levels
- Decreased mechanical wear
- Extended system service life
Retaining the variable speed configuration was critical. The SP2V system modulates pump speed in response to demand, maintaining stable pressure while reducing energy consumption, mechanical wear and noise levels compared to fixed speed alternatives. Preserving this functionality ensured the spa’s operational efficiency and environmental performance were not compromised.
Plant Room Integration
All components were supplied and fitted within one working day. The rapid turnaround ensured the spa remained fully operational with no disruption to facilities.
This project demonstrates close coordination between customer teams, engineers and site personnel to deliver a seamless outcome under time-sensitive conditions.
