Texas

Condensing instantaneous water heater with integrated storage

Texas is a condensing high performance water heater with 500 litres of storage, with outputs of 99 and 230 kW. Manufactured from duplex grade stainless steel, the Texas water heater is defined by its patented Helical Fire Tube heat exchanger, offering low pressure drop and large surface area for maximum heat transfer. The Texas water heater is the perfect product selection when significant peak demand and continuous flow of DHW is a major requirement.

Design

The nature of Duplex stainless steel and its corrosion-resistant properties make it the perfect choice for installations where the water may be particularly rich in chlorides, such as sports centres, swimming pools, campsites, hotels, spas, and many more.

When designing the Texas, consideration was taken to ensure we delivered a product with a small footprint allowing easy installation in plantrooms with space constraints.

Up to 6.900 litres/hour from a 1 m2 footprint

Consideration was taken when designing Texas to ensure as small a footprint as possible, allowing easy installation in plantrooms with space constraints. All models in the Texas range have a width that allows an easy passage through a 90 cm wide doorway, ensuring easy access to the plantroom and occupy only 1 m2 floor space once installed.

Domestic hot water always in condensation

Texas water heater fully condenses thanks to the specific geometry of the Helical heat exchanger which exposes the cold-water supply to the cooled flue gasses by condensing them in the bottom part of the unit. The water then travels up countercurrent to the flow of the flue gasses, significantly increasing the heat transfer, thermal efficiency and performance. The integrated circulation pump maximises the uniformity of temperature inside the storage tank and helps eliminates the risk of legionella.
