This 1/2 inch bronze combination fill valve and backflow preventer is for use in commercial and residential hydronic heating systems to provide make-up water to the boiler and prevent backflow when supply pressure falls below system pressure. It consists of a bronze backflow preventer, model 9D, and a bronze feed water pressure regulator, model 1156F, in one pre-assembled unit. The high capacity fill valve provides quick system filling and purging. It is designed for use in the boiler feed lines of hydronic heating systems and has 1/2 inch union solder inlet x NPT threaded outlet connections. The maximum pressure is 100 psi (6.9 bar).

This installation is typically very slow to respond and can take up to two days to heat (depending on the thickness of the slab and the amount of floor insulation used). However it is more economical to run, especially combined with proper insulation.

Hydronic in slab heating is the most popular way of installing hydronic floor heating. It is a storage heating system that uses the thermal mass of the slab to store heat.

There are three possible ways to install hydronic underfloor heating: directly in the slab, in the screed or using diffusions plates with the most common being slab heating.

Since hydronic floor heating is a central heating system, we recommend non-programmable thermostats for your installation. These thermostats can be linked to your home automation systems.

With in slab heating, once the slab is heated through, the heat radiates from the floor upwards into the room. This creates a comfortable and gently heated environment with no draughts, dust or noise.
