Tubular heaters

"RC" internal coating (WRAS approved material)

Stainless steel AISI 316L tank

The U-tube heater cylinder is designed for semiinstantaneous domestic hot water (DHW) production
systems for use in service sector or industrial premises. It amasses a reserve of water through an exchanger fixed directly onto the tank and fed by a primary water circuit (heating hot water), low pressure vapour or any energy recovery system.

The volume is sufficient to meet peaks in consumption without temperature fluctuations. The volume/power ratio is calculated according to the consumption profile (importance, duration and frequency of drawing).
The electric water heater is available in three different versions of tank to meet all needs:

Advantages

Multi-purpose: Particularly suited for use with solar energy recovery systems, heat pumps (preheating) or solid or gaseous fuel boilers.
• Significant hot water storage capacity to meet peaks in demand.
Temperature stability for distributed DHW.
Rapid reheating: considerable power.
Less heat generator operating cycles.
• Can be used at a constant temperature of up to 95°C (depending on the model).
Cost-effective solution (heating element directly integrated into the tank).
Quick and easy to install: equipment delivered to site with pre-assembled insulation and heating systems (can be
easily removed if required).
Easy to maintain: removable heaters.
Extended warranty for stainless steel version.
Non-standard versions available on request.
