UNIQUE HYBRID SYSTEM
The Daikin Altherma hybrid heat pump is a unique combination of a high efficiency gas combi boiler and renewable energy air-to-water heat pump.
Unlike other available boiler-heat pump combinations, it works in series rather than in parallel. This means the flow of one can feed into the return of the other in certain economical operating modes.
MINIMAL RUNNING COSTS
The boiler and heat pump can run in combination or in isolation, to maximise energy-efficiency and minimise running costs. The system comprises of a single combined indoor unit, plus an outdoor heat pump unit. The indoor unit's compact size means it can usually be fitted easily into the same space as the boiler it is replacing.
The Daikin Altherma hybrid heat pump is a domestic Renewable Heat Incentive (dRHI) ready heating system.
SMART HYBRID LOGIC
The Daikin Altherma hybrid heat pump is controlled by smart hybrid logic. This automatically selects the most cost-effective heating mode at any time of day or night, all year-round.
It takes into account external temperatures and internal heat and hot water demand, as well as the relative cost of gas and electricity.
Home-owners and tenants can input their latest energy tariffs so that the smart hybrid logic control can identify the most economical operating mode. It maximises the use of the heat pump as long as this is more cost-efficient than using the gas boiler.
COST-EFFICIENT OPERATING MODES
At any time, the smart logic selects one of four available operating modes to ensure the most economical performance:
FOR REPLACING GAS AND LPG BOILERS
The Daikin Altherma hybrid heat pump is ideal for replacing on-gas and LPG boilers as there's no need to replace existing radiators and pipework.
The Hybrid is most suited to properties with heat loads from 12kW-20kW, but can cover heat loads up to 27kW.
- Heat pump only: ideal in mild temperatures. Heat pump capacity and efficiency is high enough to satisfy total demand
- First hybrid mode: operational when outdoor temperature drops. Heat pump efficiency falls but continues to operate. Boiler provides additional heat requir
- Second hybrid mode: comes into use when the outdoor temperature drops further and the heat pump efficiency reduces. The unique flow control automatically regulates the variable speed pump to slow the flow rate. This raises the heat pump efficiency for as long as possible before switching totally to boiler mode.
- Boiler only: When the outdoor temperature is very low, the system temperature requirement is highest. In these conditions, the pump is less economical, so only the boiler operates.
