Bradford White Infiniti tankless water heaters with SRT
The Infiniti tankless water heaters combine the energy- and space-saving features characteristic of tankless water heaters with new technologies and designs that significantly reduce scale build-up, reduce maintenance, improve performance and provide greater installation flexibility. Each unit is equipped with the SRT Scale Reduction Technology system, which uses multiple components to reduce scale by disturbing water flow and greatly reducing hotspots that allow scale to accumulate.
To minimize water temperature fluctuation during hot water usage, the Infiniti condensing model is equipped with an automatic and fully modulating bypass. Together with temperature sensors located throughout the unit, temperature stability throughout the draw remains consistent resulting in a better user experience.
Giving design engineers and installing contractors a wider array of venting options and configurations, the Infiniti condensing model is approved for use with PVC, CPVC, ABS and polypropylene, and is available with an optional “up and out” concentric vent kit requiring only one penetration through the wall or roof.
The water heaters are ENERGY STAR qualified and include both condensing and non-condensing residential models with 199,000 BTU inputs. Additional features include an easy-to-use, built-in digital control, built-in freeze protection, low NOx emissions, an optional outdoor installation kit, and a limited 12-year warranty on the heat exchanger and a limited five-year warranty on all parts.

Eemax skidded combo systems
Eemax now offers skidded systems, pairing electric tankless water heaters with storage tanks to reap the best benefits of both products. These skidded combo systems can handle low-flow and high-flow dump applications equally well. A temperature control switch activates a pump, which circulates water through the tankless heater, eliminating issues with low flow turn-on and decreasing the peak power-sizing requirement. Eemax can size and fabricate the entire skidded system, floor-mounted or wall-hung, based on the customer’s demand and electrical capacity.

Stiebel Eltron Mini E thermostatic tankless water heaters
The Mini E thermostatic tankless water heaters are an electronically controlled version of the mechanical Mini water heaters. The electronic control board and automatic flow control allow Mini E models to deliver water at factory preset temperature of 100 F. Custom preset output temps are also available. They’ll maintain temperature, even with pressure fluctuations in the water supply, which is perfect for installations where output temperatures are limited by code.
Unlike the mechanical units, which will only service a single sink, the Mini E 6-2 can be plumbed to supply warm water to multiple sinks in warm climates. The unit offers a seven-year warranty against leakage and three years on all components.
