The flow and return pipes are mounted one inside the other (1, 2) and freely connected together at the end (8, 9) furthest from the boiler. The inner pipe can act as the return pipe to the boiler, while the radiators (11) are connected to the outer one. The resistance in the ...

A central heating and cooling system comprising two independent circuits of the singe-tube type, a cold circuit which is coupled with its outgoing and return lines to a central cold-production machine and a hot circuit, also with outgoing and return lines coupled to a boiler or boilers, or ...
provide perimeter heating. Room air heated by the resistance element rises and is replaced by cooler room air, establishing a continuousconvective flowof warm air while in operation. By superior design and proper placement under a window area, the electric baseboard case causes air to flow ...
flow ofhot waterthrough each tubing loop via a system of zoning valves or pumps and thermostats. The thermostat can be set several degrees lower, compared with other types of central heating systems, providing in this way energy saving, but the system does not respond quickly to temperature ...

When the solar heating proves insufficient, the first three-way valve transfers, directing the return flow through the second valve. This directs the flow in the first instance through the heat pump, and a relay circuit containing a timer comes into action. If, after a certain time, the ...
pump upstream of its exchanger and a nonreturn valve downstream of its exchanger, flow through the branch line being from a first point on the associated main conduit to a second point on the associated main conduit, the first point being downstream of the second point with respect to flow ...
Volume control dampers are specially designed for use in heating, ventilating and air conditioning systems for volume, and flow and pressure control of air within the ducts. 1. Easy to install. 2. They run efficiently and quietly, leaving homeowners t...
4, The induction heating body is not easy to leak water and leakage, and its service life is more than 20 years. 5, Fast temperature rise and high thermal efficiency. 6, It has a durable circulating water pump imported from Germ...
