The complete range of Sunniva heat pumps
From a warm pool to 120 °C process heat
Fourteen categories on one ladder. Every Sunniva Heat pump does the same thing — moves heat instead of burning something to make it — and what separates them is how hot they will take the water, and how much of it. Start with the temperature you need.
The range, by temperature
Published maximum water outletEach bar is the hottest water that category is published to deliver. Darker means hotter. Select a bar to open that range.
Bars show maximum water outlet temperature only; capacity is printed beside them, not plotted. All in One, Monoblock, Domestic Split Unit, Geothermal, the dryer and the storage tanks are not on the chart — they publish no maximum water outlet figure, and the dryer moves heat into air rather than into water. Every figure also appears in the list below.
All fourteen categories
Grouped by dutySanitary hot water first, then pool duty, then the ranges that go hotter — followed by the ground-coupled range, the dryer and the storage tanks that pair with any of them.
Hot water to 60 °C
Sanitary hot water, from a farmhouse to a campus 5 categories
All in One Heat Pump
Heat pump and enamelled tank in a single cabinet — one unit, one connection, nothing to plumb between.
Monoblock Heat Pump
Compact monoblock with the circulation pump built in. Heating through winter, cooling in summer as an option.
Domestic Split Unit
Outdoor unit outside, cylinder indoors, refrigerant between them — so nothing hot runs through the wall and the cylinder can sit where the bathroom is.
Commercial Heat Pump
The workhorse range for bulk sanitary hot water, from a small hotel block to a full campus.
EVI Heat Pump
Enhanced vapour injection holds 60 °C output with the ambient at −25 °C, and needs no auxiliary heater to do it.
Pool duty
Water held at swimming temperature, year round 1 category
Swimming Pool Heat Pump
Titanium-in-PVC-shell exchanger built for chlorinated water. Heating in winter, cooling in summer as an option.
Hot water & process to 80 °C
Where a boiler used to be the only answer 2 categories
High Temperature Heat Pump
80 °C sanitary and process water without a boiler, across an ambient range of 7 – 43 °C.
Water Source Heat Pump
Hot and chilled water from the same machine at the same time — no fans, no dependence on the ambient.
Industrial process heat
95 – 120 °C, at plant scale 2 categories
Super High Temperature Heat Pump
Plant-scale process heat to 95 °C on low-GWP R515B, up to a megawatt of heating.
Ultra High Temperature Heat Pump
120 °C process water on an R245fa circuit, and it holds that output independent of the ambient.
Ground coupled
A source that barely moves through the year 1 category
Geothermal Heat Pump
Ground-coupled exchange against a temperature that stays near-constant, summer or winter.
Drying
Heat pumps that take the water out instead of putting it in 1 category
Heat Pump Dryer
The same closed cycle, pointed the other way: it dries the air, warms it and sends it back round, so the heat is recovered instead of vented up a flue.
Storage
Tanks to pair with any source 2 categories
Glass Lined Tanks
Vitreous enamel fused to steel at 900 °C, CFC-free PU insulation, Incoloy 800 element and a magnesium anode.
Ceramic Lined Tanks
Ceramic-coated against corrosion, 50 mm rockwool under aluminium cladding. Pressurised or non-pressurised.
Not sure which rung you are on?
Tell us the draw-off pattern, the water temperature you need and the ambient it has to work in. We will size it — and say so if a smaller machine will do.
