Toshiba heat pump - common questions
Toshiba has over 150 years of engineering heritage and a strong reputation in air conditioning and HVAC globally. The Estia heat pump range carries this reliability into home heating. Field data from UK installations to date has been positive, though the UK install base is smaller than Mitsubishi or Daikin so long-term data is more limited.
The Toshiba Estia Split achieves SCOP up to 4.4 on smaller models. This places it among the more efficient brands in the UK market. The split design (separate indoor and outdoor unit) can also offer some installation flexibility.
Yes. Toshiba Estia heat pumps are MCS-approved and eligible for the £7,500 BUS grant, provided installation is carried out by an MCS-certified installer.
Toshiba uses R32 refrigerant across most of their Estia range. R32 has a Global Warming Potential (GWP) of 675 — significantly lower than the older R410A (GWP 2088). This is better for the environment and aligns with the UK's F-Gas regulations.
