STIEBEL ELTRON launches cascade units: one flow and return for up to 6 heat pumps
As part of their hpnext generation of heat pumps STIEBEL ELTRON have announced an accessory for their new air source range that allows up to 6 units to be joined in cascade with only one flow and return and one electrical connection into the building.
The AHP-CM cascade units, which exist in variants for 3,4,5 or 6 connections, help simplify and speed installation and make for a sleek finished look with less damage to the building envelope and less piping.
In addition to the advantages of faster, neater installation the AHP-CM is also increases system efficiency. They lower energy use because they allow the use of smaller pumps than otherwise would be required.
The units are designed to match the new design aesthetic of the hpnext range so that they are visually harmonious with the rest of the external plant.
“These cascade units are just one of the many unique design improvements and accessories that make our hpnext series stand out in the market,” said John Felgate, Managing Director of STIEBEL ELTRON.
“With an R290 refrigerant, higher than ever efficiencies and lower than ever sound values we’re really excited to introduce our partners to a completely new platform across all our ranges. Performance improvements mean that units can cover a wider than ever range of buildings and projects with higher flow temperatures and lower modulation points.
“Thought has been given to every design decision to make installation easier and more attractive. Over 40,000 hours of lab testing and 3 years of field testing mean we are delivering a proven, robust and safe solution that has been refined to maximise every benefit for both installers and end customers.
“As an example of the attention to detail, the cascade unit has been given not only the same look at the heat pumps, but the same footprint, so that the feet kits needed to raise the unit up in snow drift or flood prone areas can also be used for the cascade unit.”
