The full-power Voltura: 36 kW, digital control, no storage tank.

The Voltura TP36E is the heavyweight of the range, delivering 36 kW at 240V. That is twice the TP18E's rated heating power and 50 percent more than the TP24E. For a larger household or a project where cold incoming water demands more from the heater, this is the Voltura to put at the top of the shortlist. Our heater-map class covers 1.5-to-2 bathrooms in cold climates, 2-to-2.5 in moderate climates or 3 in warm climates.

Its power is paired with automatic modulation, not just an on/off command. Water-flow and temperature sensors help the unit adjust element power to maintain the selected outlet temperature within available capacity. Front controls and the digital display keep operation straightforward, with a maximum temperature selection of 125 degrees Fahrenheit. Three-quarter-inch NPT connections, a 0.5 GPM activation threshold and booster-compatible preheated inlet water add useful detail to the high-capacity package.

The biggest model requires the most electrical planning: four dedicated 240V feeds, four 40A double-pole breakers and a maximum current of 150A. It is an indoor, upright wall-mounted heater, with its own clear installation and maintenance requirements. For the customer who needs the strongest Voltura option rather than a larger storage cylinder, the TP36E brings the full 36 kW digital platform and a five-year limited original-owner warranty.
