Geothermal — a source that barely moves all year
Ground-coupled exchange against a temperature that stays near-constant, summer or winter. Heating, cooling and process water from the most stable source there is.
Full technical data sheets for this range are being prepared. Ask us for the current selection table and we will send it the same day.
Is this the right range for you?
Two minutes here saves a wasted quotation. The boundaries below are the published ones, not sales judgement.
Yes, if all of these are true
- You have land or borehole access for a ground loop
- You want heating and cooling from one system
- You are building new, where trenching is cheap
- Long system life matters more than lowest first cost
Look at another range if
- You have no ground access — see Water Source Heat Pump
- It is a retrofit with no space to dig — see EVI Heat Pump
- You only need hot water — see Commercial Heat Pump
Applications
Where this range is normally installed.
Key features
What is inside the cabinet, and why each of them is there.
Ground loop against a near-constant source temperature
Heating, cooling and hot water from one installation
No outdoor coil, no defrost cycle, no winter derating
Very long system life — the ground loop outlasts the machine
Benefits
What this range does for the building, rather than what is in the box.
The most stable source available
A few metres down, the ground hardly notices the season. That is the highest and steadiest COP any heat pump can achieve.
Nothing outdoors to see or hear
No fans, no outdoor unit, no noise complaint from the neighbours.
Decades of life in the loop
The buried pipework typically outlives two or three generations of machine.
And what every Sunniva heat pump gives you
True of the whole range, not just this one.
- Up to 75 % off water heating against electric, LPG or PNG
- Quick payback and strong return on investment
- The longest product life of any common water-heating technology
- Silent operation
- Hot water round the year, independent of sunlight
- Lower carbon emissions
- Negligible maintenance cost
- Saves space against a boiler or a solar-thermal field
Common questions
The ones our engineers are actually asked.
How much land does a ground loop need?
Why is it more efficient than air source?
When will full data be available?
Downloads and related ranges
Performance figures are published test data at the stated conditions and are not a guarantee for a specific installation. Draw-off pattern, pipe runs, water quality, static head and local code all affect the final selection — confirm with Sunniva Encon LLP before ordering.
