Adlår’s dual heat pump systems achieve seasonal efficiencies (SCOP) of up to 5+. 

In practical terms, that means: 
For every 1 unit of electricity used, up to 5 units of heat are delivered into your home. 

A gas boiler or electric UFH, by contrast, can never exceed 1:1 output relative to fuel input and real-world performance is often lower. 

This multiplier effect is the foundation of lower running costs. But efficiency is not fixed and it depends on operating conditions. 

Many comparisons assume worst-case operation. High flow temperatures running constantly at 50–55°C. That is a peak design condition, not how a well-optimised system should run day to day. 

Heat pumps become more efficient at lower flow temperatures. 
Lower flow temperature = higher COP. 
Higher COP = less electricity used. 

Adlår systems are designed to operate “low and steady”, using intelligent weather-compensated heat curves that automatically adjust output in response to outdoor conditions. 

Instead of repeatedly reheating a cooled house at high temperature, the system maintains comfort continuously and efficiently to protect seasonal performance. 

Your real-world running costs will follow how the system is operated and not just the theoretical maximum heat demand calculated under MCS assumptions. 

Most air source heat pump systems use a single outdoor unit to deliver both: 

• Space heating 

• Hot water 

When the system diverts to heat hot water, it must temporarily prioritise higher temperatures. That shift reduces overall stability and can lower real-world efficiency. 

Adlår’s dual system separates the two: 

• The Aurora II is dedicated solely to space heating 

• The Fjord cylinder independently produces hot water 

This separation prevents efficiency disruption, maintains stable operating conditions, and protects seasonal performance which directly protects your energy bill. 

Stability equals efficiency. Efficiency equals lower cost. 

MCS design calculations often assume continuous heating across the full season. In reality, most households use timed morning and evening peaks heating patterns, lower temperatures overnight, and reduced output when the home is empty. 

Adlår systems reward this real-world behaviour. 

By combining: 

• Intelligent setback strategies 

• Lower background flow temperatures 

• Short, efficient comfort boosts 

The system operates where heat pumps perform best at lower average flow temperatures with minimal cycling. 

The result is reduced electricity consumption compared to high-temperature, stop-start heating. 

Every Adlår system is commissioned with: 

• Weather-responsive heat curves 

• Precision flow temperature control 

• Inverter-driven modulation 

• Compatibility with heat pump–optimised tariffs 

Running low and steadily allows the system to take advantage of favourable electricity pricing structures where appropriate to further improving cost efficiency. 

This is not reactive heating. It is engineered optimisation. 

When you combine: 

• 4× efficiency 

• Protected seasonal performance 

• Dual-system stability 

• Lower flow temperatures 

• Real-world operating optimisation 

…you don’t just get renewable heating. You get predictable, controllable, financially intelligent heating designed to lower bills from day one and over the long term.
