Three ways to save money on your heatpump running costs

Three ways to save money on your heatpump running costs:
Modern domestic heatpumps are by design extremely energy efficient, but these three top tips will help keep cash in your pocket.


Clean it
Regular cleaning of your heatpump’s filters will help keep your machine in tip top condition and running efficiently.  To clean the filters, open the unit’s front panel and gently remove the filters. First vacuum them with a soft brush attachment and then wash in lukewarm water with a splash of mild dish-washing detergent.  Once dry, replace them in the machine.  If the filters won’t come clean, it’s time to replace them.  If you have titanium apatite photocatalytic air purifying filters, refer to the cleaning instructions in your owner’s manual.

Also, regularly clear around the outside unit so that there is no dirt, debris or foliage anywhere near the unit.


Set it on low, let it go
You may have heard that running your heatpump all-day every-day over winter is more energy efficient and cost effective than using it on an as required basis.  Well, depending on your circumstances this can be true.  It certainly was for one of our happy customers!

One of our clients reported power savings when they switched from using their heatpump as required to following the all-day every-day method.  A 4.5 KW wall mounted heatpump services the client’s large open plan kitchen/living/dining area.  The heatpump was set to 15°C and left to run day and night throughout winter, as ESP had recommended. In the mornings and evenings, when the family was in the dining and living rooms, the temperature was boosted to 19°C or 20°C.

At night, while the family slept, the heatpump dropped back down to 15°C, which helped keep the chill out of the home.

Our experts explain that the low-level day and night heating of the home helps keep the air dryer, which in turn helps keep moisture from  the moisture-holding materials in the home, such as carpet, furnishings, drapes and even the building itself. When the air is dry, it’s easier and cheaper to maintain the ambient air temperature and boost the temperature by several degrees when the family is around.

The most expensive phase of warming air is the initial start-up phase when the unit is working hard to raise the air temperature in the home to the desired level. Once there, if the heatpump is allowed to operate as designed, maintaining the desired temperature becomes cost-effective. When the home or room is kept at a minimum temperature of 15˚C, the cost of warming the room to a comfortable level is significantly reduced.

ESP provides advice on operation at the time of installation or whenever you need it – just give them a call to find out how to get the best out of your heatpump.


Service it
An annual service ensures your machine is operating as efficiently as it should and can troubleshoot any maintenance issues.  A service includes inspection of all operations and parts, thermostat-setting diagnostics, lubrication of moving parts, checking refrigerant levels (if required), pipework insulation and electrical connections, and cleaning the condensate drain, evaporator, condenser coils and blower components.

Autumn is the ideal time for annual servicing, when the heatpump is predominantly used for winter heating.  If your unit gets most use in summer, as an air conditioner, then make sure it’s booked for its annual service in spring.
