Grant can supply a range of heat pump accessories that are compatible with all our Grant Aerona³ models. These accessories are available to purchase individually or as part of a pack.
Cylinders
Grant have a range of options to suit all needs and locations
Sealed System Kits
Sealed system kits are available to suit all of our Aerona3 heat pump models. These kits are available in 3 sizes, 12ltr, 18ltr and 50ltr. The kits include expansion vessel, filling loop, pressure gauge, PRV and air vent.
Flexi-foot kit with fixings
The flexi foot kit comprises of 2 x 600mm feet for mounting the Aerona3 heat pump range. These feet serve both as anti-vibration mounts and also raise the heat pump from the ground.
Through wall insulation kit
This comprises of a heavy-duty flexi hose in 22-28mm specifically designed to connect onto the Aerona3 heat pump range. Available for 6 & 10kW only.
Domestic hot water (DHW) boost kits
Our DHW time boost kit is used to control the cylinders electric immersion. The Aerona3 heat pump range will maintain the cylinder temperature at 45-55°C. The time boost kit is then used to raise the cylinders temperature once a week to provide Legionella protection.
Mag One Filter
The Grant Mag One Filter is used to prevent against breakdowns caused by both magnetic and non-ferrous particulates in the central heating system. The triple action filter collects all types of magnetites and non-ferrous debris in the system.
Wiring Centre
The Grant Wiring centre is a pre-configured electronic wiring centre that allows the installer to connect controls (stats, clocks etc), pumps, motorised valves etc together in a coherent and simple to understand manner. The Grant wiring centre does all the complicated cross wiring during installation and all that remains for the installer is to connect to the heat pump.
Glycol
Antifreeze which is installed into the heating system to prevent against freezing.
Buffer vessel
The Grant Aerona3 heat pump range is complimented by either a 50ltr buffer with built in 3kW immersion or a 30l volumizer. Both provide volume to the system to prevent the heat pump from short cycling.
Air source heat pumps use basic thermodynamic principles to convert thermal energy contained withing the air we breathe to heat energy that can be used to provide heating and hot water. This "ambient heat" is replenished by the sun making our heat pumps both effective and environmentally friendly.
How Heat Pumps Work
There are two basic types of air source heat pump - "air to air" and "air to water". Grant Aerona3 heat pumps use an air to water system which utilises heat energy captured from the air in "wet" heating systems radiators or underfloor heating. The process uses the same vapour/compression cycle that extracts heat in a domestic fridge. A refrigerant with a low boiling point is exposed to external air temperatures in an evaporator. The liquid boils off to a gas and absorbs the thermal energy of the air. This gas is then compressed increasing the heat energy contained within the refrigerant, before passing through a heat exchanger where it condenses back to a liquid form, whilst transferring the heat to the water of the heating system. The liquid refrigerant is then re-circulated through the evaporator and the cycle is repeated.
Fit for the Future
With the recent fluctuations in price and supply of fossil fuels, air source heat pumps offer both an environmentally and economically sustainable alternative. Home heating accounts for approximately 30% of CO2 emissions. The heat source used by Grant Aerona3 heat pumps is entirely renewable which helps reduce the amount of harmful greenhouse gases being released into the atmosphere and, in doing so, lowers the carbon footprint of the household.
Lower Heating Costs
Compared with other domestic heating methods, the Grant Aerona3 can benefit homeowners by creating annual savings on fuel bills. The units can deliver over four times the amount of energy for every 1kW of electricity used depending on the flow temperature and the climate conditions prevailing at the time. Homes utilising this type of heat generator will obviously have a lower dependency on fossil fuels, making them less susceptible to rising fuel costs.
