LTV manifold

For low temperature systems you use the LTV-manifold from Robot Underfloor Heating. The LTV is suitable for main and supplementary heating, for example a heating systems with low supply temperatures (60°C/40°C), heating systems with a modulating burner, systems on solar energy and heat pumps.

Since mentioned heat sources produce a lower flow temperature than a conventional heating source, the mass flow should be primary magnificated to supply a sufficient heating power to the floor. The LTV-manifold are therefore fitted with a regulating valve, which makes it possible to arrange the floor return-water flow. A pressure differential can also be created allowing the circulation pump to suck more supply water. Clever technique for a competitieve price.

  • suitable for systems with lowtemperature supply, HR CV-boilers with modulating burner, heating systems on solar energy and heat pumps
  • low-temperature system: up to 60°C supply (primary)
  • available 1-10 group
  • adjustable under-floor supply and return water (secondary)
  • Grundfos circulation pump
