Connecting chamber for hot water heating system has the water feeds through a porous filter to separate out particles and air

A connecting chamber for a hot water heating system is fitted between the boiler and the system and connects the input and output of the system through a vertical chamber. Both the supply and return feds are passed through the chamber with a vertical offset to create an S-shaped path. A porous filter element is fitted over at least the hot water feed and enhances the separation of particular debris and air from the water flow. Air collects in the top of the chamber under a venting valve, debris and sludge collect in the bottom of the chamber over a drain plug. The filter elements can be made of perforated stainless steel, plastic or any suitable materials.

The strength of the insulation, is varied such that one end of the tank has less insulativity than the other end of the tank. Preferably change occurs gradually along the axial length of the tank. The second system for providing passive energy management is using insulation formed of a material that has a glass phase change temperature at or near the temperature of the water when it enters the tank.

Collector for distributing a heat transfer fluid in a heating and/or cooling and/or conditioning network, in particular of household and/or industrial type

A collector for distributing a heat transfer fluid in a heating and/or cooling and/or conditioning network, in particular of household and/or industrial type, includes a housing having: a first terminal portion, open for the entry of the fluid into the collector; a second terminal portion, open for the exit of the fluid from the collector; a duct, which extends from the first terminal portion to the second terminal portion for the passage of the fluid in the housing of the collector, wherein the collector has a shut-off valve positioned at least partly in the duct and including a movable obstructor for adjusting the opening and/or closing of a passage in the duct. The collector further includes: a chamber that communicates with the duct through the passage, in particular when the shut-off valve is in a condition in which it opens the passage, and a plurality of ports that communicate with the chamber, in particular each port being adapted to be associated with a respective branching pipe.
