Abstract

The economizer for heating small quantities of water adjacent to the point of use includes an electric water heater with a heat exchanger element, an on/off push button switch, and inline regulator valves. One valve is fitted to a cold water supply from a storage tank or mains supply. The other valve is fitted to a pipe to supply hot water for a basin/bidet etc. The regulator valves allow adjustment of water flow rate irrespective of water pressure. An overheat relay isolates the electric supply in the event of water overheating. A warning light indicates when the electric supply is connected to the heat exchanger element.

    1. irax-murr. nenefts.:ou'd acc-e in 'hew Build' applicat ores, but ccr. siderable savings would also result -.Trnere e.;isting services zze ad-. ted. With'New Build considerable savings in instE>llat on costs are assures as ogler a cold feed is reuired.Thus the pine run from water storage tank, fn tinge, lagging of pinework and lassoer ccss Eve elmirated; possibly cost savings exceecTirg the cost of the 'co'-omize'urit.
    2.7hen needing hot water to head basin,bidet etc. ncrmGl'y l tot gallon c' cold water is drawn off, and goes directly to waste, wh 1st writing for hot' water to arrive at the tap; -, to gallon Of '-dot' water is the' used for washing handsfece, shaving eta. the 'rot' ripe run is the- e t full of hot water, which slowly cissipetes to the sur.-_ud ng atmosphere to no purpose. 'in summer, this could even add to uwa ted he:,t within the property.
    thus a saving of water heating costs, es well as the actual cost of the *. water is effected.
    3,. With r..y Aster.., only Et cold feed is taken to the bas-n/bidet, and a 'I' is taken off this supply like to feed the economizer unit, which in turn feeds The trot' tap. the ecoror."izer butt t is sit-a ed adjacent to the asir/7b-det, where these visits are is tee sa.n.e room orgy one U-ti' 'S required.
    4. In'existing supply' cases, '1' above does no apply, be all running cost savings are relevant.
    5. I estimate that a 2.5k- heating element w--.:ld suffice, Basely a small water flow Bate is needed;thus the electric supply could be conveniently joined into a new or existing Or ng-main' system.
    c. I estimate that th-s unit could retail for a maximum of 25, so would be cheaper than installing a corvential system fo.- 'hot aver' in new build'.
    Both 'New Build' and 'existing' systems would imr!edately benefit from savings in running costs.
    7. lmbe furl me Nebula or' aloes are to allow for easy fitting to ipewo-k, as well as providing adjustment of 'water flow rate' at installation, to allowed a suitable floater ter.7perature at the tan, irrespective of the water pressure existing, whether this be direct from eve mains supply or from storage Lank.
