Tritherm Manifold Pump and Mixing Valve Control Pack
£153.00 – £200.00Price range: £153.00 through £200.00 excl VAT
- Complete mixing unit for underfloor heating manifolds.
- Maintains water temperature between 35°C-60°C.
- Includes thermostatic blending valve and high-efficiency pump (Choice of Grundfos, Wilo, or Bastion).
- Fits 210mm manifold centres.
The Tritherm Heating Pump Control Pack is a comprehensive solution designed to maintain the precise water temperature required for underfloor heating systems. It bolts directly onto standard distribution manifolds (210mm centres) and blends high-temperature water from the boiler with cooler return water to ensure safe and efficient heating.
This pack is the core of the manifold control system, providing a quick and simple installation for optimal UFH performance .

Efficient Temperature Control
The thermostatic blending valve is the heart of the system. It ensures that the water entering the underfloor heating pipes never exceeds the safe temperature limit for the floor finish, while maintaining enough heat for comfort.
- Blending Function: Mixes hot water (e.g., from the boiler) with cooler return water to achieve the target UFH temperature.
- Safety: Operating at lower temperatures than radiator systems prevents damage to floor coverings and improves energy efficiency.
- Bypass Recommendation: If the primary circuit does not have an automatic bypass valve, it is recommended to install one to improve system efficiency.
Pump Variations
The control pack is available with one of three high-efficiency circulating pumps to suit your preference or specification requirements. All options are compliant with modern energy efficiency standards.
- Grundfos UPM3 Flex AS: A reliable, high-efficiency pump featuring a user interface with LED indication, PWM signal control capability, and multiple performance curves .
- Wilo Para: A proven, high-efficiency pump known for its compact design and robust performance in heating applications.
- Bastion Pump (ZL-3002): A cost-effective high-efficiency alternative featuring push-button control and multiple constant speed or proportional pressure settings.
