Owning a heat pump is a great way to keep your home energy-efficient, but like any system, it requires regular care. Annual servicing not only keeps your unit running smoothly but also saves you money over time. A well-maintained heat pump uses less energy, which means lower electricity bills each month. Routine checks also help detect small problems—such as minor leaks or worn parts—before they turn into costly breakdowns. Professional servicing extends the lifespan of your

Solar hot water systems are a fantastic way to save money and reduce your carbon footprint. However, to keep them operating at peak performance, regular maintenance is essential. Over time, components such as pumps, valves, and panels can wear down or become less efficient. Annual servicing helps identify and fix small issues before they escalate into costly repairs. Maintenance also ensures that your system continues to provide reliable hot water throughout the year, even du

The L9 error code on a Mitsubishi Electric Ecodan Air Source Heat Pump indicates a low water flow rate in the primary pipework circuit. This could be due to: Water circulation issues, Air in the circuit, and A zone valve or pump that isn't energizing You can try looking for restrictions in the water circuit, such as damaged pipework or valves or flexes that may be kinked.

One of the main differences between a boiler and a heat pump is that a boiler delivers the same temperature consistently to the home, whereas a heat pump will modulate its flow temperature according to the outside air temperature. The colder it is outside, the warmer the radiators will be inside. Often heat pump owners swapping from a boiler to a heat pump take at least a year to get used to the way a heat pump works. An oil/gas boiler effectively blasts heat into a home us

Anyone living in England, Scotland or Wales can apply for government grants that cut the cost of installing an air source heat pump. Find out which grants you can apply for. In England and Wales, the main available heat pump grant is the Boiler Upgrade Scheme (BUS), which offers up to £7,500 towards the cost of an air source or ground source heat pump. This scheme provides an upfront grant that is applied for by the installer on your behalf. To be eligible, you must have a va

Nesta has launched a new scheme for people interested in air source heat pumps to visit homes of recently installed heat pumps. If you’re considering getting an air source heat pump it’s a great opportunity to ask real homeowners the questions you can’t find answers to online. If you’re already enjoying life with an air source heat pump, you can sign up to become a host and share your experience with others. https://www.nesta.org.uk/project/visit-a-heat-pump/ Book Your Annual

I recommend booking a regular, annual service for your air source heat pump, which will help maintain its manufacturer's warranty and keep it working at its best. Air source heat pumps usually require less maintenance than a traditional boiler, so you'll probably find the annual check-up to be quicker and more straightforward than you're used to. But rest assured I will spend my time on site to get the best out of your heat pump and give it a service of the highest quality to

It sounds really obvious, but one of the biggest differences between your air source heat pump and a traditional boiler is that your heat pump lives outside. Nobody’s ever needed to weed out vegetation from the cupboard where a boiler sits. However, it’s worth keeping an eye on the area around your air source heat pump and getting rid of any leaves, plants or branches that are getting in the way of vents or pipes. Clear away any other debris, rubbish or garden toys from the a

If you’re going away for a break, you might be tempted to give your heat pump a holiday too. However, I would advise against turning it off completely. Your heat pump will need to use more energy getting your home back up to temperature than it would keeping it warm while you're away. If you wait to turn your heat pump on until you walk back through the door, you'll have to wait to be warm while it catches up. Heat pumps warm homes more slowly, but much more efficiently and i

You can set up your air source heat pump to respond to the temperature outside so that it increases the flow temperature of your system when it’s colder and reduces it when it’s warmer. Experimenting with your compensation settings on the air source heat pump keeps your home up to the temperature you’ve specified on your thermostat without using more energy than it needs to on warmer days. Different heat pumps have different types of weather compensation settings. I can set t

Often I find rooms in customer houses with radiators turned off, mostly in rooms that are used for storage. After all, it doesn’t make sense to pay to heat a room with nobody in it. However, this approach won’t really work with an air source heat pump, which is designed to keep your whole house at a comfortable temperature. If you turn off radiators in certain rooms, you’ll throw out the balance of your system. Asking your heat pump to heat fewer rooms than it was designed to

One of the first lessons that air source heat pump owners learn is that it costs less to keep your heat pump running all the time, day and night than it does to turn it off and on. Air source heat pumps have a lower flow temperature (the temperature of the water that they pump through your system) than gas boilers, which makes them much more energy efficient. They’re designed to keep your home at a constant temperature rather than pumping out a lot of heat quickly. You'll sav
