The range

From a single room to a commercial build

Three families: the ‘U’ units (add your own buffer and pump), the ‘Ub’ units (buffer tank and circulation pump built in), and the ThermoPlus inverter units that also make hot water.

‘U’ series — buffer & pump optional

Plant-room units; specify the buffer and pump to suit.

Underfloor outputs are nominal ratings. We size the unit and buffer to your floor area, zones and flow before we quote — ask and we’ll work it out with you.

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.

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 is the ThermoPlus (THD) range?

A newer inverter (variable-speed) line that can run underfloor heating and make high-temperature hot water from the same unit, with efficiency that climbs as it modulates. A good fit when you want one unit doing both jobs.

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).
