Professional TMV Servicing & Legionella Remedial Works in Bolton

AAC Gas specialise in TMV servicing and Legionella remedial correction for commercial and industrial sites. With over 20 years’ experience, we deliver expert testing, maintenance and practical remedial solutions that keep your hot and cold water systems safe and fully compliant.

We work exclusively with commercial and industrial clients — never domestic properties — supporting environments where water safety is critical.

Why Regular TMV Servicing Matters in Bolton

Thermostatic Mixing Valves (TMVs) are essential safety devices that blend hot and cold water to deliver safe outlet temperatures and prevent scalding.Over time and with constant usage, the non-return valves inside TMVs can fail. This allows cold water to flow back into the hot water system (backflow). As a result:

• Hot water return temperatures drop significantly
• Boilers and calorifiers struggle to reach the correct temperature
• Heating plant runs constantly (non-stop) trying to compensate
• Energy consumption and costs increase dramatically
• Risk of system inefficiency and potential compliance issues rises

Regular TMV servicing prevents these costly and dangerous problems before they escalate.
