What is the SEER2 rating of the TOSOT TUD60-48W2/NHE-D(U)?

The TOSOT TUD60-48W2/NHE-D(U) is rated at up to 19.0 SEER2 and 11.7 EER2 for cooling and up to 10.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 4 certified matchups SEER2 ranges from 16.0-19.0.

Is the TOSOT TUD60-48W2/NHE-D(U) good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 54,000 BTU/h at 5°F with a COP of 2.10, so it is still 2.1 times as efficient as electric resistance heat at that temperature.

How much does the TOSOT TUD60-48W2/NHE-D(U) cost to run per year?

At its rated efficiency it costs about $1,286-$3,416 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,582 in Phoenix and $2,852 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the TOSOT TUD60-48W2/NHE-D(U) the same as the GREE GFU60HP230V1R32AO?

Yes, as far as the certified ratings go. ENERGY STAR lists 4 model numbers with identical efficiency, capacity and matchups, which means the same outdoor unit sold under a different brand or with a minor variant code (voltage, colour or region). The full list is on this page.

Which indoor units work with the TOSOT TUD60-48W2/NHE-D(U)?

ENERGY STAR lists 4 certified combinations for this outdoor unit. The highest-rated ones use TUD48AH2/NHG-D(U), TUD60AH2/NHG-D(U), TCAC48H/NHA.

A good fit if…

You want low cooling bills - its SEER2 beats 85% of central heat pumps.
Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 54,000 BTU/h at 5°F.
It will heat most of the year - its HSPF2 beats 84% of central heat pumps.
You want steady temperatures and quiet running - the compressor varies its speed.

Think twice if…

Nothing stands out - its ratings have no weak spot for its class.
