Tips & Advice

Learn how to operate and maintain your heat pump system for maximum efficiency, lower electricity bills, and longer lifespan.

Annual servicing is required to maintain your manufacturer/distributor warranty.
Only approved and trained engineers can service your system under warranty terms.
DIY or unqualified servicing will void your warranty.
A valid warranty saves you costly repairs, ensures priority call-outs, and peace of mind during breakdowns.
Warranty durations vary by brand and begins on the date of commissioning.

Set domestic hot water (DHW) as low as 41°C to achieve ~43°C and reduce energy costs.
Set DHW to 48°C if you require longer showers or have a larger household.
Radiator flow temperatures should be around 45°C for efficiency.
Underfloor heating can run between 35–40°C due to higher efficiency.
Scalding can occur at 45°C, especially for children.

Check and clean the outdoor unit's drainage tube to prevent sludge or leaf build-up.
Blocked drains can lead to corrosion, ice build-up, and damage to components like the compressor or fan blade.
This cleaning should be part of your annual heat pump service.

Power off your heat pump in advance of planned electricity outages to avoid post-outage fault alarms.
If a fault occurs, reset by switching off both indoor and outdoor isolators for 30 seconds, then power back on.
After restarting, wait for the system to complete its power-up sequence before using the control panel.

Unlike oil/gas systems, heat pumps use low-temperature water (30-45°C) with slow heat-up response times.
Set a consistent room temperature (e.g. 21-22°C downstairs, 18-19°C upstairs) and avoid daily temp fluctuations.
Using timers or schedules disrupts the heat pump's ability to maintain a steady 1°C differential, increasing costs and reducing comfort.
Heat pumps are most efficient when running continuously at low temperatures rather than cycling on/off.
Reduce stats to 12°C in summer to keep the system on standby without unnecessary activation.
