A hose for feeding cold or hot water, which can be easily bent even at a small radius so that it can be applied in a small piping space, which is free of kink, and which can accommodate running water containing chlorine, is provided. The hose for feeding cold or hot water includes: an inner layer formed of an elastic tube; an inner reinforcing layer formed of a fiber yarn wound in a spiral provided on the inner layer; and an outer reinforcing layer formed of a woven metallic hard wire provided o...

A water tap having a tap body, separate connections on the tap body for receiving supplies of hot water H, cold water C and further liquid F, a common discharge spout mounted on the tap body, and valves for controlling the supply of hot water H, cold water C and further liquid F from the tap body to the discharge spout, in which: the discharge spout is provided internally with two separate discharge passages which lead to a common discharge outlet; the tap body defines a route for hot water only...

An improved water heater for use in spas, hot tubs, pools, hydrotherapy pools, bath tubs, and similar bodies of water used indoors, outdoors, or both indoors and outdoors are used for both therapeutic and recreational purposes. The water heater uses heating element technology know as thick film on substrate comprising resistive elements bonded to the outer dry surface of a pipe to heat the pipe which in turn heats the water flowing therethrough. The heater is highly efficient due to the direct c...

A water heater which includes a heat exchanger having a first passage and a second passage connected with the first passage, a gas burner mounted within the first passage, a push blower having an outlet conmected with the gas burner for forcing air into the gas burner, and a water reservoir mounted surrounding the heat exchanger, whereby when the gas burner is turned on, the push blower will be turned on to force air into the gas burner thereby forcing combustion air generated from fire of the g...

According to the present invention, in a water supply apparatus which converts output power of a solar cell with an inverter to drive a motor pump for pumping up water, a DC brushless motor having no sensor for detecting a position of a rotatable shaft is used as a motor for driving the pump. Further, the water supply apparatus, having a pump and a frequency converter for supplying electric power to the pump and controlling a rotational speed of the pump, includes a standard current value table ...

A water heater is provided in which neutralization process of drain is not required and an excellent heat efficiency is achieved. A route of exhaust gas which is passing through the main heat exchanger 18 is divided into a first exhaust gas chamber 23 having a secondary heat exchanger 19 and a second exhaust gas chamber 24 having a drain evaporator. Because of this, hot exhaust gas which is passing through only the main heat exchanger 18 flows into both the secondary heat exchanger 19 and the dr...

Water purifier includes a container having a room, a filtering material disposed in the room for purifying water for catching particles and fungi such as polio viruses. The filtering material is a sintered activated carbon block filter having pores. The filtering material preferably has a first filtering material and a second filtering material. One thing out of the first filtering material and the second filtering material is formed of a sintered activated carbon block filter whose average pore...

A water diverter that diverts water flow from under siding or external fascia on a building to the environment in regions adjacent a portal, such as a window, door or vent. The water diverter includes a first wall, a base joined with the first wall, and an outer wall joined with the base. In an upper portion the first wall, base and outer wall form a collector that collects water flowing along a building wall or the portal structure. In a lower region, the first wall, base and outer wall coopera...

A combined water feature and planter is in the form of a rectangular trough formed by a one-piece plastics material hollow moulded shell. A base of the planter has drainage openings therein leading to respective drainage passages which extend through a water reservoir for water recycled through an ornamental pump. The drainage passages are thus isolated from the water reservoir so that liquid draining through the passages to the exterior of the trough does not mix with the water recycling throug...

A water tank made of stainless steel and having a substantially cylindrical shape is provided. The water tank comprises curved stainless steel panels forming a cylindrical body of the water tank, fan-shaped stainless steel panels forming a cone-shaped top part and a cone-shaped bottom part of the water tank, packing members being inserted between connecting portions of the stainless steel panels, reinforcing members, each having an L-shaped cross-section, which are arranged on both side of the c...
