Toshiba Carrier UK rolls out ESTIA heat pumps on lower GWP refrigerant R-32

Toshiba Carrier UK has rolled out the latest generation of its high-performance ESTIA air-to-water heat pumps operating on lower global warming potential (GWP) refrigerant R-32.

ESTIA, operating with R-32 refrigerant, provides highly efficient space heating and domestic hot water (DHW) for year-round comfort in homes and small businesses. Designed to meet increasing demand for a lower-carbon alternative to traditional heating technologies, ESTIA units harness ambient thermal energy from outdoor air, reducing energy bills compared to some other types of units. The heat pumps support Carrier’s 2030 Environmental, Social & Governance (ESG) Goals of reducing customer’s carbon footprint by more than 1 gigaton. Four models are available in the ESTIA range, spanning capacities from 4 to 11kW, with larger capacities available soon, all with reversible operation to provide cooling as well as heating, if required. At the heart of ESTIA is Toshiba's award-winning twin rotary compressor, which contributes to the system's outstanding energy efficiency rating of A+++.

The pioneering compressor enables the heat pump to continue supplying hot water to the heating network even during exceptionally cold weather, delivering water at 62°C when outdoor temperatures fall to -25°C. At the other end of the temperature scale, ESTIA can continue producing DHW at exceptionally high outdoor temperatures (43°C) to deliver maximum running cost savings.

'With its top A+++ efficiency rating and ability to continue operating in low ambienttemperatures, ESTIA provides a superb solution for homeowners or small businesses looking to replace less efficient units,' said David McSherry, head of sales, Toshiba Carrier UK.

“For installers, ESTIA is quick and easy to install on site, and Toshiba’s renowned reliability means a long working life, backed by our excellent warranty.” For gas boiler replacement projects, Toshiba offers a space-saving wall-mounted hydro-module with a choice of 150l, 200l or 300l capacity external cylinders. For use in new-build projects, an all-in-one floor-standing hydro-module with an integrated 210 litre tankprovides a super-compact solution for both heating and DHW storage.

To ensure continuity of operation at extreme low ambient air temperature during winter, ESTIA is equipped with an integrated back-up electrical heater (3, 6 or 9kW) to maintain heating and hot water production at all times. For contractors, ESTIA is quick and easy to install and maintain, with hydro-modules providing front access to all key components. A new software start-up tool allows set-up parameters to be quickly programmed without laying a hand on the unit.

For end users, Toshiba's elegant Home AC Control App gives access to comfort settings while at home or, remotely, while away. This function is compatible with Google Assistant. As part of the ESTIA roll-out, TCUK recently opened a new heat pump showroom to demonstrate the system’s capabilities, equipped with working systems. The facility enables customers to see the full range of ESTIA options, including outdoor condensing units, DHWstorage systems, hydro-modules and the company's all-in-one solution containing both storage vessel and hydro-module, ideal for use in newbuild properties. Supporting the opening were members of the local Sale Sharks rugby team, for which Toshiba is this season's Big Screen Sponsor. Star players in attendance included Aaron Reed (Wing/Centre) and Jean Paul Du Preez (Lock).
