Energy-Efficient Toshiba Heating And Cooling Systems Used With Solar PV Help Future-Proof Cheshire Home

High-performance Toshiba heating and cooling equipment has been used in combination with a solar photovoltaic (PV) and battery storage system as part of a project to help future-proof a five-bedroom home in Cheshire.

Toshiba Carrier UK Ltd (TCUK) is part of Carrier Global Corporation, the global provider of healthy, safe, sustainable, and intelligent building and cold chain solutions.

Toshiba ESTIA air-to-water heat pumps

Two 11kW Toshiba ESTIA air-to-water heat pumps operating on lower global warming potential (GWP) refrigerant R-32 were installed at the 5,500ft2 property, alongside two Toshiba MiNi VRF systems.

The Toshiba solution replaced an inefficient heating system and is supported by a 16kW solar PV installation plus 11kW of battery storage and measures including triple-glazing.

Energy-neutral outdoor and indoor units 

Homeowner and renewables consultant - Dave Meseck says the property is “energy-neutral” during the summer months, with generated and stored energy offsetting electricity consumed from the grid. 

One of the ESTIA systems serves around 90m2 of underfloor heating in the open-plan kitchen and dining area, while the other provides hot water and heats the upstairs radiators and towel rails from a supplied 300-liter cylinder. The ESTIA indoor units include a 3kW backup heater to ensure continuity of operation at extremely low ambient air temperatures.

Toshiba Mini SMMSe VRF

The 5hp system provides heating and cooling for the room above a triple garage via a 5.6kW four-way cassette

A 6hp (15.5kW) Toshiba Mini SMMSe VRF is connected to ducted units in the bedrooms and two of the newly designed compact 3.6kW one-way cassettes downstairs, which have been designed to fit between the joists on a traditional home.

The second 5hp (14kW) system provides heating and cooling for the room above a triple garage via a 5.6kW Toshiba four-way cassette, while the garage space below, where a spa area is planned, is served by two wall-mounted units.

Efficiency

“The whole system has been running since December last year and the way it has transformed the house is fantastic,’’ said David Meseck, a Specialist in renewables, sustainability, and the circular economy.

He adds, “It was important to get everything right; the project was sized correctly and the equipment installed properly."

Cost-effective all-electric heating system

As well as helping to future-proof our home and reducing energy costs, the changes have added value to the property"

David Meseck continues, "Together with the other measures, we now have an efficient, all-electric heating system with the added benefit of cooling in summer, and the annual servicing cost is comparable to boiler cover. As well as helping to future-proof our home and reducing energy costs, the changes have added value to the property."

He adds, "I would urge anyone looking to invest in their home to look at the bigger picture and make it an environmentally-responsible investment.’’

Four models are available in the ESTIA range, spanning capacities from 4-11kW, all with reversible operation to provide cooling as well as heating if required.

twin rotary compressor

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 compressor enables the heat pump to continue supplying hot water even during exceptionally cold weather, delivering water at 62 degrees C when outdoor temperatures fall to -25 degrees C. ESTIA can also continue producing DHW at exceptionally high outdoor temperatures (43 degrees C) to deliver maximum running cost savings.

all-in-one floor-standing hydro-module

Toshiba offers a space-saving wall-mounted hydro-module for boiler replacement projects such as this, with a choice of 150l, 200l, or 300l capacity external cylinders.

For new-build projects, an all-in-one floor-standing hydro-module with an integrated 210l tank provides a compact solution for both heating and DHW storage.

Easy-to-install

ESTIA provides a superb solution for homeowners or small businesses looking to replace less efficient systems"

“ESTIA provides a superb solution for homeowners or small businesses looking to replace less efficient systems," said David McSherry, David McSherry, Head of Sales for Toshiba Air Conditioning UK, Carrier Global Comfort Solutions Europe.

“It is quick and easy to install on-site, and Toshiba’s renowned reliability means a long working life, backed by our excellent warranty.”

Performance, warranty, and reliability

Installer - Peter Franks, Managing Director of Mansfield-based Woburn Mechanical Services Ltd, added, “This is by some distance the biggest domestic project we have undertaken. The customer knew exactly what he wanted and now has a comprehensive heating and cooling system."

Peter Franks concludes, "The Toshiba equipment is excellent in terms of performance and reliability and comes with a seven-year warranty. We wouldn’t be fitting it if we didn’t have complete confidence in it.’’
