    Monoblock heat pumps — pump built in, plug and pipe

    Specifically designed for Indian conditions. Comes with an inbuilt water circulation pump, so installation is limited to connecting pipes and plugging it in.

    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

    • A home, small hotel or boarding house
    • You want an outdoor unit with an indoor or nearby tank
    • You are backing up or replacing a solar water heater
    • Your winter stays above about −7 °C

    Look at another range if

    • You want the tank and machine in one cabinet — see All in One Heat Pump
    • You need more than about 1,000 litres a day — see Commercial Heat Pump
    • It is a swimming pool — see Swimming Pool Heat Pump

    Applications

    Where this range is normally installed.

    Hotels
    Motels
    Boarding houses
    Solar water heater backup
    Independent homes

    Key features

    What is inside the cabinet, and why each of them is there.

    Panasonic or equivalent high-efficiency rotary compressor

    Inbuilt circulation pump

    Automatic defrosting

    Closed loop system possible

    Low noise and vibration

    Safe, reliable and stable running

    Intelligent control

    Easy to install

    Benefits

    What this range does for the building, rather than what is in the box.

    The pump is already in it

    No separate circulator to select, wire or find space for. Connect flow and return and it runs.

    Excellent solar backup

    Sits behind a solar water heater and covers the mornings, the monsoon and the cloudy week.

    Long working life

    Fewer external components is fewer things to fail, and rotary compressors at this duty are very long-lived.

    Which size do you need?

    Our domestic sizing tool is in preparation. Tell us the number of people and the tank you have, and we will size it against your actual draw-off.

    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.

    What does the inbuilt pump save me?
    A separate circulator has to be selected for the head and flow, wired, controlled and housed. Having it inside the machine removes all four decisions and the commonest cause of a badly performing installation, which is a pump that does not match the circuit.
    Can it cool as well as heat?
    Cooling is available as an option on parts of the range. Ask us for the specific model — it is not standard on every unit.
    What tank should I pair it with?
    Two to six times the machine's hourly output is the rule that applies across all Sunniva ranges. Our glass lined and ceramic lined tanks are built for exactly this duty.
