Rinnai INFINITY 28e Liters External Natural gas Water Heater is an instantaneous type domestic hot water producer for outdoor installation with electronic temperature management to the degree via remote control, installable at any point of use and control of water flow rate.
Corrosion-resistant enameled galvanized steel shell and standard antifreeze down to -20°C. As an instantaneous producer, as opposed to a storage tank that keeps a stock of water at a high temperature warm to have it available when needed, Infinity produces hot water only upon actual withdrawal. This means consumption savings and environmental friendliness.
This model can run an external circulator (optional) in domestic systems equipped with domestic hot water recirculation to immediately supply hot water to the desired location, according to the "economy" or "comfort" mode at the user's discretion. Infinity 28e can be cascaded with other appliances up to a maximum of 25 units through the use of special "master" electronic boards.
Energy efficiency class A, below in "Certifications" find the energy label.
Installation:
- This water heater was created for outdoor, space-saving installation. Exhaust fumes are expelled from the front slit, no chimney is needed. Installation is fast and economical, partly due to the compact size. The front panel is made of galvanized enameled steel, which is corrosion-resistant. By means of the antifreeze down to -20°C included as standard, the water heater withstands even the coldest temperatures without the need for additional protection.
Efficiency:
- Energy efficiency class A. Infinity 28e is an instantaneous water heater. It produces hot water only when the faucet is turned on, so it does not waste energy. Thanks to the absence of water stagnation, it avoids the risk of Legionella Pneumophila formation, a respiratory disease that is very risky for people's health.
Functionality:
- Like every Rinnai outdoor water heater, it comes standard with a remote control that the user can have installed in any room. From the control, you adjust and change the operation of the water heater at your discretion. With a progressive LC code, the user notices any limescale deposits, which are harmful to the machine, and can have the Technician intervene in time. Infinity has the special feature of controlling the water temperature to the degree. If it is installed far from the utilities and the pipes generate heat loss, the Technician can activate the additional function of perfecting the temperature at the tap: +1°C to +3°C
Accessories:
- Up to 3 accessory remote controls can be connected to a water heater, for example, one in a kitchen and one in each bathroom, for maximum comfort. To conceal water and gas connections, the installation can be completed with the custom-made fitting cover.
