{"product_id":"voltura-tp18e-18kw-electric-tankless-water-heater","title":"Voltura TP18E 18 kW 240V Electric Tankless Water Heater","description":"\u003ch2\u003eWhole-house ambition, with digital control doing the thinking.\u003c\/h2\u003e\n\u003cp\u003eThe Voltura TP18E is where the lineup changes character. Its 18 kW output steps beyond the compact dial-controlled heaters into digital, automatically modulating tankless heating. In our heater-map sizing classes, it is a practical starting point for 1.5-to-2 bathrooms in moderate climates or 2-to-2.5 bathrooms in warm climates. For many two-bath homes, this is the entry point worth looking at when moving away from a storage tank.\u003c\/p\u003e\n\u003cp\u003eThe useful upgrade is not just the display on the front. Water-flow and temperature sensors help the TP18E adjust power to the heating elements to maintain your selected outlet temperature within its available capacity. Front power and temperature buttons keep control accessible, with a maximum setting of 125 degrees Fahrenheit. It activates at 0.5 GPM, and the 18 kW model uses 1\/2-inch NPT water connections.\u003c\/p\u003e\n\u003cp\u003eThis is an indoor, wall-mounted heater with real electrical requirements: two separate 240V circuits, each protected by a 40A double-pole breaker, and 75A maximum listed current. It can also accept preheated water as a booster, adding another useful application to the digital platform. For the right household, the TP18E delivers a strong mix of capacity, automatic control and a five-year limited original-owner warranty without jumping straight to the larger models.\u003c\/p\u003e\n\u003ch5\u003eDetails\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e18 kW at 240V with automatic power modulation\u003c\/li\u003e\n\u003cli\u003eSizing class: 1.5-2 baths moderate climates or 2-2.5 baths warm climates\u003c\/li\u003e\n\u003cli\u003eDigital display with power and temperature-selection buttons\u003c\/li\u003e\n\u003cli\u003eTwo dedicated 240V feeds;
