Frequently Asked Questions
Is Daikin a good heat pump brand?
Daikin is one of the world's largest HVAC manufacturers with over 90 years of experience. The Daikin Altherma 3 consistently achieves SCOP ratings of 3.8-4.5, meaning it generates up to 4.5 units of heat per unit of electricity consumed. Independent tests by MCS and the European Heat Pump Association consistently rank Daikin among the top performers for UK climates.
How much does a Daikin Altherma 3 cost?
A Daikin Altherma 3 installation in East Anglia costs £12,000-£18,000 before the £7,500 Boiler Upgrade Scheme grant, giving a net cost of approximately £4,500-£10,500. The exact price depends on property size, insulation levels, and whether any radiator upgrades are needed. We provide a detailed quote including all costs after your free home assessment.
What is the SCOP rating of the Daikin Altherma 3?
The Daikin Altherma 3 achieves SCOP ratings of 3.8 to 4.5 depending on flow temperature and model. At 35°C flow temperature (ideal for underfloor heating), SCOP reaches 4.5. At 55°C (for existing radiators), SCOP is approximately 3.0-3.5. This means for every £1 of electricity, you get £3.00-£4.50 worth of heat.
Does the Daikin Altherma work in cold East Anglia winters?
East Anglia rarely experiences temperatures below -5°C, well within the comfortable operating range of the Daikin Altherma 3 (rated to -25°C). The Altherma maintains full heating capacity down to -15°C and continues to operate efficiently at all UK winter temperatures. Our local customers report consistently warm homes throughout January and February.
How long does Daikin Altherma installation take?
Installation typically takes 2-4 days for the heat pump itself. This includes the outdoor unit, indoor cylinder, controls wiring, and commissioning. If radiator upgrades are required (we assess this during the survey), additional time may be needed. We aim to minimise disruption and ensure your heating is fully operational each evening during the installation process.
