HeatUp app · iOS / Android

Luxury comfort, always within reach. The free ACOND HeatUp mobile app gives full system control — set heating, cooling, and hot water modes, adjust setpoints, view live status, schedules, and energy consumption. A single account supports multiple buildings — useful for landlords, property managers, and CleverBloom service plan visibility.

Weekly scheduling per zone

Independent temperature setpoints and time programmes per heating zone. Bedrooms cooler than living areas at night. Weekend schedules different from weekdays. Holiday mode drops everything to frost protection. All configured once on the app, then runs automatically.

Real-time energy monitor

Live kWh consumption visible in the app — see exactly what your heating is costing per day, per week, per month. Compare seasons. Identify the rooms or schedules that drive consumption. Particularly useful when paired with solar PV — see when the heat pump runs on free roof energy vs grid.

Weather compensation

Auto-adjusts water temperature before you feel cold. Reads outdoor temperature, predicts heat demand, and modulates output continuously. Keeps the system running at peak SCOP without manual setpoint chasing — the homeowner just sets a comfortable room temperature and the controller does the rest.

Multi-zone temperature

Independent room temperature control across the property. Each zone valve and room thermostat reports back to the controller. Bedrooms can run at 18°C while the living area runs at 21°C. Empty zones default to frost protection. Optimises both comfort and running cost.

Filter and service alerts

CleverBloom service plan visibility through the same control architecture. Push notifications when annual service is due, when filters need a check, or when the heat exchanger is approaching a recommended deep clean. No surprise breakdowns from missed maintenance.

Remote diagnostics by ACOND

ACOND monitors connected units remotely from their service centre in the Czech Republic. Most warranty cases can be diagnosed without a site visit — sensor logs, water temperatures, compressor performance all visible to the manufacturer. Faster fixes, lower service cost, longer system life.

Cloud connected · OTA updates

WiFi connection to ACOND cloud. Firmware updates pushed over-the-air — controller logic, app features, and bug fixes installed automatically. The unit you buy this year keeps getting better through its 20-year design life. No need for installer site visits to apply software updates.

Smart home integration

Optional building-control protocol integration with home automation systems — Loxone, KNX (via gateway), Crestron, or any compatible building-management systems. Configurable as part of the project for clients running whole-house automation. Most domestic clients run the HeatUp app standalone; smart home integration is an upgrade path when needed.

1 · ACOND Aconomis R outdoor unit

The heat pump itself. Variable-speed twin rotary compressor with natural refrigerant — propane (R290), 15 kW heating output. Stainless steel housing. 4× efficient (492% efficient, A++, certified), COP 5.12 at A7/W35. Sits on a concrete pad or wall brackets — outdoor unit only, no refrigerant lines run indoor (all-in-one).

2 · Indoor controller

Smart electrical control unit — the indoor brain of the system. Houses the controller, weather compensation logic, RCD protection, and HeatUp app connection. Pump, valves, expansion vessel, and cylinder are site-built around it. Smaller indoor footprint than a Grandis indoor unit — fits a utility room or plant cupboard.

3 · Hot water cylinder

Indirect cylinder, 210–250L typical for a 3–4 bed home. Heat-pump-priority charging brings the cylinder up to temperature from the heat pump alone for normal demand. Weekly anti-legionella cycle automatic. Tight space? Replace with a Sunamp Thermino phase-change battery (4× smaller — see Works With section below).

4 · Buffer tank

Thermal store between heat pump and radiator or floor loops. Stops the heat pump short-cycling when demand fluctuates, gives the system stable water temperatures, and gives the variable-speed inverter time to find its optimal modulation point. Typically 60–100L for a 3–4 bed system.

5 · Pipework & materials

Insulated water pipes between outdoor unit and indoor controller. Stainless steel or copper to MCS standards, insulation rated for outdoor exposure. Cable run for outdoor unit electrical supply, RCD wiring, and outdoor temperature sensor. All sized at survey to suit the routing — short runs reduce pipework cost, long runs need more insulation.

6 · Water treatment

Magnetic filter and corrosion inhibitor on the heating circuit — protects the heat exchanger from sludge and prevents corrosion. Manufacturer warranty requirement. In hard-water regions like London, an Ecosoft softener on the cylinder feed prevents limescale build-up that would otherwise degrade efficiency over time.

5 year manufacturer warranty

ACOND warrants the Grandis R for 5 years from commissioning as standard. Optional extension to 7 years available when the system is on a CleverBloom annual service plan — the inspection record satisfies ACOND's extended-warranty conditions. Both parts and labour covered.

20 year design life

ACOND publishes a 20-year design life on the Grandis range. Heavy-duty stainless steel housing resists coastal salt and urban pollution. Variable-speed twin rotary compressor with inverter control modulates output continuously — fewer hard starts, less mechanical wear, longer service life than fixed-speed alternatives. Serviceable components throughout, no proprietary failure points.

propane future-proof

Propane (R290) is a natural refrigerant safe from upcoming EU regulations that restrict synthetic refrigerants. No risk of expensive refrigerant replacement during the unit's service life — unlike R32 or R410A systems where supply will tighten and prices will rise as phase-down progresses. Propane (R290) has roughly 1,000× lower climate impact than R32.

MCS certified

Every Grandis R installed by a government-approved (MCS-certified) installer qualifies for the £7,500 government grant and complies with government noise and performance standards (MCS 020). CleverBloom is MCS-certified and handles the grant application end-to-end. Grant deducted upfront from your invoice on approval.

Water treatment

A magnetic filter and corrosion inhibitor protect the heat pump's heat exchanger from sludge and scale. Treated system water is a manufacturer warranty requirement — untreated systems are typically excluded from cover. The combination keeps efficiency steady, prevents pump and valve failures, and means fewer service callouts over the life of the unit.

Water softener

An Ecosoft softener removes calcium and magnesium from the feed water before it reaches the heat pump. In hard-water regions like London, this stops limescale forming on the heat exchanger surfaces — the single biggest cause of efficiency drop-off and component failure in air-to-water heat pumps. With a softener fitted, the system runs at design performance for decades instead of degrading year by year.
