The Grant Aerona3 10kW Air Source Heat Pump, supplied with a 210 litre pre-plumbed hot water cylinder and full installation pack, provides efficient, low-carbon heating and hot water for medium-sized UK homes. This inverter-driven, monobloc heat pump runs on R32 refrigerant and achieves a SCOP of up to 5.20 at 35°C flow – one of the highest efficiencies in the Aerona3 range.

Weather Compensation Built In
The Aerona3 continuously adjusts flow temperature based on outdoor conditions, automatically optimising running efficiency without manual intervention from the homeowner.
DNO Notification Required
All Grant Aerona3 installations must be notified or approved by the local Distribution Network Operator (DNO). For the HPID10R32, retrospective notification within 28 days may be possible where maximum demand is 32A or less and eligibility criteria are met; always confirm current requirements with the relevant DNO before installation.
Confirm Installation Pack Configuration
Grant offers six different installation pack configurations (Packs A, B, C, K, L, M) depending on whether an S-Plan or 3-port diverter valve system is used and whether the cylinder is pre-plumbed. Confirm the pack configuration matches the intended system layout before installation begins.
DC Inverter Technology
Smoothly varies compressor, fan and pump speed to match real-time heating demand, reducing on/off cycling and keeping running costs low as outdoor conditions change.
Strong Mid-Range Efficiency
The 10kW model delivers the highest SCOP in the Aerona3 range at both 35°C and 55°C flow temperatures, making it a strong efficiency choice for medium-demand properties.
Quiet Twin-Rotary Compressor
Rated at 53 dB(A) sound pressure at 1 metre, the high-efficiency DC twin-rotary compressor supports quiet operation suitable for typical UK plot sizes.
Automatic Frost Protection
A factory-fitted base tray heater activates at 2.5°C ambient to prevent condensate freezing in the unit base, switching off automatically at 5.5°C.
210 Litre Pre-Plumbed Cylinder
The cylinder arrives with heat pump-specific plumbing and controls factory-fitted, reducing on-site installation time compared to a standard unvented cylinder.
MCS Approved for Grant Funding Schemes
The Aerona3 range is MCS approved, supporting eligibility for UK government incentive schemes such as the Boiler Upgrade Scheme where installation criteria are met.

Frequently Asked Questions
What size property is the Aerona3 10kW suited to?
The 10kW model suits typical medium-sized UK homes. An accurate heat loss calculation for the specific property should confirm this is the correct output before purchase.
Does the 210L cylinder come pre-plumbed?
Yes, the cylinder in this bundle is pre-plumbed with heat pump-specific connections and controls already fitted, reducing on-site installation work.
What refrigerant does the Aerona3 10kW use?
It uses R32 refrigerant, with a charge of 1.55kg, factory-sealed within the monobloc unit.
Is DNO notification required before installation?
Yes. All Aerona3 installations require DNO notification or application. For the 10kW model, retrospective notification within 28 days may be possible if maximum demand is 32A or less and other criteria are met – confirm current requirements with the relevant DNO.
What is the manufacturer's warranty on this heat pump?
Grant provide a standard 2-year warranty, extendable to longer terms when installed by a Grant-certified installer under their extended warranty scheme; terms apply.
