DHW tanks and primary solar water



500 to 6000 Litres

CE compliance

Tubular heaters

"RC" internal coating (WRAS approved material)

Stainless steel AISI 316L tank

The “RECUPAC” is a cost-effective solution for producing and storing DHW from energy recovered by a heat pump.
Thanks to heat extracted from the air or the ground it is possible, via a tubular heater, to store sufficiently large quantities of hot water to meet the needs of the service or residential sectors.
If necessary, a backup system can be used to provide additional energy.
Based on the CODAP, the “RECUPAC” also fulfils the requirements of the EN13445 standard.

AdvantagesTechnical descriptionDocumentaries


Production of DHW via any kind of heat pump.
• Less heat pump operating cycles.
• Reduced operating costs (energy savings of up to 60%).
• Reduced greenhouse gas emissions.
• DHW temperature stability.
• Significant volume of hot water means that peaks in demand are met.
• Multi-purpose: can be integrated into new or existing installations.
• Delivered to site with pre-assembled insulation and thermal equipment.
• Non-standard versions are available on request.
