Questions about the units

Why aren’t the prices shown?

Because every job is different, we price each one individually. Tell us what you’re heating and we’ll send you a price — supplied, or supplied and installed.

Can one unit do the floors and all our hot water?

Yes — that’s the DuoHeat idea. Underfloor heating and stored hot water are both low-and-steady loads a single well-sized heat pump handles, with controls sharing it between them. It saves buying two units.

Do you install these, or just supply them?

Both. We can supply a unit to your own installer, or design and install the whole system ourselves and tie it into your floors, pool or hot water as needed.

What’s the difference between the ‘U’ and ‘Ub’ models?

The ‘Ub’ models have an onboard buffer tank and circulation pump built in, so there’s less to plumb and less plant-room space needed. The plain ‘U’ models leave the buffer and pump to be specified separately — handy when they’re shared with other equipment.

What warranty do they come with?

The Performance Plus range carries a two-year labour and three-year parts warranty covering the compressor, coil, heat exchanger and refrigeration system, and the titanium heat-exchanger tube is covered against corrosion for 30 years (10 years on the commercial models).
