    Triangle Tube is best known for two things: feats of hydronic innovation and incredibly efficient products. If you are looking for those qualities in your water heater, the Keystone certainly fits the bill. The Keystone tankless water heater is a high-efficiency, condensing water heater for large spaces. The condensing technology behind the Keystone will capture and reuse gaseous heat that escapes traditional water heaters. Stainless steel construction of the heat exchanger and an internal condensate trap will protect the KW 285 from corrosion. The Keystone's modulating burner scales heat production based on your needs and reduces unnecessary energy consumption. All told, the Keystone is an incredibly reliable and efficient water heating solution.

    Product Features

    Pre-Mix Burner
    The pre-mix burner on Keystone water heaters means that your water heating will be environmentally friendly and clean. Pre-mixing the fuel improves air quality and reduces NOx output to less than ten parts per million, well within the strictest low NOx guidelines.

    Easy Setup
    Keystone water heaters include several features that streamline the installation process. A large, easy-to-use display and consolidated connections at the top of the unit make setting up a Keystone quick and simple.

    Communicating
    Up to eight Keystone units may be staged together through the Keystone's controls. This allows you to expand your water heating to accommodate the largest of applications without sacrificing efficiency. The Keystone's controls also support integration into building automation systems.

    PID Staging
    The Keystone uses Proportional, Integral, Derivative (PID) logic for staging. PID staging will consider three things when deciding to activate a water heater: how far the water temperature is from the target temperature, how long the temperature has been there, and how quickly the temperature is changing. PID logic improves efficiency and averts temperature drops in your domestic hot water.

Medium Learn More
Medium
Medium refers to the substance that carries heat through the heating system. Systems are either designed to use either Hot Water or Steam as a medium, and components are usually specific to one or the other.
Hot Water
Fuel Type Learn More
Fuel Type
To create heat, some form of fuel is required. Fuel Type specifies what the product uses as an input to create heat.
Natural Gas
Combustion Type Learn More
Combustion Type
Condensing appliances use leftover thermal energy from combustion gases to heat water in a secondary heat exchanger, resulting in higher efficiency and lower exhaust temperature.
Condensing
Vent Type Learn More
Vent Type
Products that use combustion (burning) of fuel to create heat also create potentially dangerous gasses that need to be exhausted (AKA "Vented"). Depending on the product, venting can be done via a chimney, through a side wall, or use a second vent to provide fresh air to the appliance.
Direct Vent
Modulating/Staging Learn More
Modulating/Staging
Stages are unique speeds or levels that equipment can operate at. More stages allow for better fine-tuned control of output, which improves comfort and efficiency. Modulating equipment can operate across a range of levels, giving the highest level of fine-tuned control. Learn More
