The growing use of engineering plastics in these systems allows for the designing of integrated parts that were originally in metal and help to produce boilers with a lower number of assembled parts witch result in significant system cost reductions.
Heating systems are all those systems that provide heat to a building. These include heating systems like heat pumps, furnaces and boilers. Water Management focuses on boilers that can be considered special-purpose water heaters. While furnaces or heat pumps carry heat in warm air, boiler systems distribute the heat in hot water, which gives up heat as it passes through radiators or other devices in rooms throughout the house. The cooler water then returns to the boiler to be re-heated. Hot water systems are often called hydronic systems. Residential boilers generally use natural gas or heating oil for fuel. Nowadays many domestic hot water systems circulate water through plastic tubing in the floor, a system called radiant floor heating.
A typical example of the benefits in specifying Radilon® materials is the hydro-block manifold, which achieves significant system cost efficiency through design integration of a number of brass parts.
In these systems long term dimensional stability, mechanical properties and resistance to Chlorine at high temperatures are required. The combination of fresh water with disinfectants like chlorine & oxygen at high temperature creates a particularly aggressive environment for plastics due to oxidative degradation.
Other typical heating systems applications currently using Radilon® materials include:
- Heating Manifolds
- Fitting Caps for underfloor heating
- Heating flow-meters and connectors
