Two Low-cost, Life-Saving Inventions with Enormous Commercial Potential

Faster-Cheaper Hot Water, Lowers Peak Power Demand, Risks and Costs


Its the peaks that matter (Francais)

During peak wash times, the refilling cold water is so slow to get hot that millions of family multi-kilowatt (4.5kW) heaters OVERLAP ‘ON’ creating a grid’s HIGHEST PEAKS of POWER DEMAND that risk freezing blackouts, building damage, and wildfires


Colder = slower = more on = higher peaks and risks


A tank’s inward-domed bottom forces the lower heating element, thermostat and  sensor to be above it, resulting in a considerable ‘dome strata’ of cold water that, at peak wash time, takes the most time, energy and money to get hot. Peak time is when every heating minute causes more heaters to overlap, each adding to the peak power demand.


DeepHeat and SubHeat simply pre-heat that bottom strata so it gets hot faster lowering costs, overlaps, and peaks.


DeepHeat

‍ A venturi is formed through the wall of a tank’s screw-in, cold water plastic dip tube, (~10 million/year). By Bernoulli’s Principle, the flowing cold water causes the venturi to suck in hot water resulting in warm water filling the dome strata. It gets hot faster reducing peak energy use and cost, heater overlap, peak power and risk.


To make the venturi, the dip tube is partially cross-cut to create upper and lower ‘lips’. The upper lip is forced inward. (See photo below).


Single or spirally spaced venturi are located in an optimum tank strata such as upwardly adjacent the lower thermostat. Hot water is drawn from this strata 24/7 with each low-volume hot water use. The strata is automatically and thermostatically reheated using cheap, off-peak energy.

‍ 

However, during minutes-long family peak power and wash times when high-volumes of hot water are used and energy is most expensive, the refilling cold water level quickly increases, submerging the venturi thereby preserving the tank’s full store of hot water for washing.

SubHeat 

Is very different.  It is outside the tank under the dome. It heats that bottom strata using an auxiliary low-watt, ‘pancake’ heater that is simply slid under a raised tank. It may be always on, or controlled by the tank’s thermostats. A circular band-clamp seals the gap.


Although cheap, DeepHeat and SubHeat water heaters get hot faster which reduces overlap and their very expensive peak power demands, risks and costs. As well, ‘recovery time’ is faster making more hot water available from the same tank. 


Filed patent applications are for sale, a massive worldwide opportunity. 


Heaters get replaced every ~10 years. New heaters may well be mandated to incorporate these technologies for their broad and low cost societal benefit. 

Both can be retro-fitted to existing heaters on site.
