Cosmogas – where quality meets innovation

Market-leading supplier of stainless steel condensing instantaneous water heaters, Cosmogas, designs and manufactures its condensing gas- fired water heaters to ensure energy- saving benefits, without reducing the high demands of heating and DHW for residential or commercial projects. Cosmogas instantaneous, condensing and modular water heaters are designed as an alternative to large single water heaters or boilers with large storage calorifiers, and offer a very efficient, modern approach to commercial water heating.

Each module is designed and built by Cosmogas with an AISI 316 Ti (titanium) stainless steel exchanger, and can be installed as a single module water heater or alongside another module in a horizontal arrangement. They can also be fitted as a vertical stack of water heater modules one above another, with a working pressure up to 11 bar. Providing a flexible and secure approach to water heating solutions, each water heater module provides a percentage of the total system water demand.

This modular approach allows the water heaters to match a variety of load variations requested through the day or week, or during varying demand seasons. Smaller modular water heaters are physically easier to transport and handle than very large water heaters. For retrofit projects they can be installed alongside the existing water heaters as they are capable of high outputs from a compact size.

Cosmogas’s titanium water heater range can provide more than 280kW in less than 1sqm of floor space and can cascade up to 1120kW with a minimum output of 14 kW. All these water heaters have lightweight designs and will fit through a single doorway, making them ideal for roof-top or basement plant rooms and high-rise residential buildings. The range includes:

• AGUAdens Wall-hung Heaters
Available in a range of models with 16, 22 and 37l capacities and respectively with 27.5kW, 37.6kW and 64.8kW outputs, the AGUAdens Cosmogas from Hevac is a new wall-hung water heater range designed to deliver instantaneous hot water for houses, offices, sports facilities, shopping centres and large-sized spaces in general. Compact and light, AGUAdens simplifies installation, while the simple and intuitive commands make for easy use.
