Power peaks are water heating’s deadly curse (Francais)


During brief, peak hot water use times, the refilling cold water gets to ‘hot so slowly that millions of family multi-kilowatt heaters can OVERLAP ‘ON’, cascading power need into a grid’s highest PEAK POWER DEMAND that risks freezing blackouts, burst pipe damage and wildfires


Colder = slower = more on = higher peaks and risks


A tank’s inward-domed bottom forces the lower heating element and its thermostat to be above it, resulting in a considerable ‘dome strata’ of cold water (~25cm, 10”). At peak wash time it takes the most money, energy and time to get hot with every extra heating minute causes more heaters to overlap, each adding to the peak, cost and risk at peak power demand times.


DeepHeat and SubHeat pre-heat that bottom strata with off-peak power so it gets hot faster and cheaper, reducing the number of heaters that overlap on.


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,  cold water flowing past the venturi sucks in hot water resulting in warm water blast-displacing that cold bottom layer that reduces heating time, and grid-wide heater overlaps. 


To make the venturi, the thermoplastic dip tube is partially cross-cut to create upper and lower ‘lips’. The upper lip is bend inward like a tongue, to create a slight restriction. (See photo below).


Single or spirally spaced venturi are located upwardly adjacent the lower thermostat. Hot water is drawn from this strata 24/7 with each low-volume, off-peak hot water use and is reheated using existing element and thermostat with cheaper, off-peak energy.

‍ 

However, during minutes-long family peak-wash-peak power times, when hot water use is at the maximum, the refilling cold water is also at maximum so the bottom strata rises quickly to submerge the venturi in cold water thereby preserving the tank’s full store of hot water for washing.

SubHeat 

Is very different and the most effective - it is outside the tank. SubHeat heats that bottom strata using an auxiliary low-watt, ‘pancake’ heater that is slid under a strut-supported tank into the dome’s cavity. It may be always on, or controlled by the tank’s thermostats. A circular band-clamp seals the gap.


DeepHeat and SubHeat also speed recovery time so more hot water is 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.
