At brief family wash times, SLOW-TO-HOT means multi-thousands of multi-kilowatt tanks are all heating at the same time creating dangerous GRID POWER PEAKS. The bottom however, is cold. When this cold layer reaches the upper element, it takes the longest to get ‘HOT’ so many-more heaters come ‘ON’ making peaks even higher that risk blackouts, frozen bodies, burst pipe damage, even wildfires.

DeepHeat - SubHeat heat that bottom for cheaper, faster hot water, lower peaks and risks.


DeepHeat and SubHeat pre-heat the bottom with off-peak power so it gets hot faster and cheaper. Both can be retro-fitted to existing heaters on site.


DeepHeat

‍ A venturi is formed in the wall of a tank’s screw-in, cold water, plastic dip tube. 

The Bernoulli Principle causes cold water flowing past the venturi to draw in surrounding hot water making for a warm, faster heating bottom layer.


To make the venturi, the thermoplastic dip tube is partially cross-cut to create upper and lower ‘lips’. The upper lip is bent inward slightly to form a ‘Bernoulli deflector”. (See photo below). Single or spirally spaced venturi are located close to the lower thermostat. 

The venturi draws in hot water 24/7, with each and every hot water use. This warm is further heated as per normal, but with cheaper, off-peak energy. In addition the invention covers the venturi’s vertical placement, whereby, during peak-wash times, refilling cold water  rises quickly submerging the venturi to preserve the tank’s hot water for washing.

SubHeat 

Is very different and the more effective. SubHeat is an external low-watt, ‘pancake’ heater in 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.
