Frequently Asked Questions
Got questions about HIU repairs or servicing in Earl's Court? Below are some of the most common queries we receive. If you need more information, feel free to contact our team — we’re always happy to help.
Are your engineers based in Earl's Court?
Yes. Our team operates throughout the Earl's Court and West Brompton areas, allowing for rapid deployment to local HIU service calls.
What is a HIU service?
A HIU service involves inspecting, cleaning, and testing the unit to ensure it runs efficiently and safely. Regular servicing helps prevent breakdowns and keeps heating and hot water flowing reliably.
How often should a HIU be serviced?
We recommend servicing your HIU once a year. Regular maintenance extends the unit's lifespan, improves performance, and ensures early detection of potential faults.
What are the signs my HIU needs servicing?
Common signs include low water pressure, inconsistent heating, no hot water, unusual noises, or leaks. If you notice any of these, it’s time to book a service.
What does a HIU service include?
A standard service includes safety checks, cleaning filters, inspecting components, testing flow rates, checking pressure levels, and ensuring the unit operates correctly.
How long does a HIU service take?
A typical HIU service takes between 60–90 minutes, depending on the condition of the unit and whether any repairs or part replacements are needed.
Do I need to turn anything off before my HIU is serviced?
No preparation is usually required. Our engineers will take care of everything upon arrival and will advise if any temporary shutdown is needed during the service.
Can you repair my HIU if there’s a fault during the service?
Yes. If we identify a fault during the service, we’ll explain the issue and provide a clear quote for the repair. With your approval, we’ll aim to fix it during the same visit.
Are your HIU engineers qualified?
Yes, all our engineers are fully trained, certified, and experienced in working with a wide range of HIU systems in residential and commercial settings.
Is there a call-out fee in Earl's Court?
We’re fully transparent with our pricing. A call-out fee may apply for HIU servicing or repairs in Earl's Court, but this will always be clearly explained before any work begins.
Do you offer bulk servicing for Earl's Court apartment blocks?
Yes. We provide tailored maintenance contracts for block managers and housing associations across Earl's Court, ensuring consistent thermal efficiency across all units.
Is a HIU gas or electric?
A HIU itself doesn’t use gas or electricity directly for heating; it transfers heat from a central plant or district system to an individual property using heat exchangers. The system supplying the HIU may be gas-powered.
How long does a HIU last?
With regular servicing and proper maintenance, a HIU can last between 10–15 years. Some systems may last longer depending on usage and system design.
How much does a HIU cost to install or replace?
Installation or replacement costs vary depending on the system type and complexity. We provide clear, no-obligation quotes based on your specific setup and needs.
What’s the difference between a HIU and a boiler?
A boiler generates heat within a property, while a HIU draws heat from a central system and transfers it into your home for heating and hot water—ideal for flats with district heating.
Can you service any brand of HIU?
Yes. Our engineers are experienced with all major HIU brands and models, including Evinox, Danfoss, Altecnic, and more.
What does an HIU service in an Earl's Court flat include?
We perform a comprehensive check of the heat transfer logic, including filter cleaning, safety valve testing, and ensuring the unit is effectively drawing heat from the building's central plant room.
