Specialist Alde caravan heating, servicing and repairs
Keeping an Alde caravan heating system running reliably requires specialised knowledge.
Topping up an Alde system with cheap automotive antifreeze leads to quiet, severe internal acid corrosion over time. Whether you need a routine fluid flush to protect your heating system or targeted fault-finding to fix an unexpected breakdown, we start every job with precise diagnostics rather than expensive guesswork.
We deliver full-service Alde repairs and maintenance from our Middleton workshop, with mobile support available throughout Canterbury. We are happy to talk it through first, so do send us an enquiry.

Alde fluid changed to approved specification
An Alde system does two jobs from one unit: heating the van and the water, pumping fluid through radiators. You feel radiant heat, not blown air, and that fluid is what gets serviced.
Alde approves four heating fluids; G12 Plus or G13 covers most systems here. Automotive coolant not approved for the system can cause corrosion or blockages.
Old fluid turns acidic, so we check it whenever an Alde-equipped van comes in for a check up or a self-containment inspection. Every change is recorded on the Alde label with date, volume and remaining fluid life, so the record stays with the van when it changes owner.

Specialist Alde Heating Solutions
Alde heating offers the ultimate in luxury travel, delivering quiet, even warmth that turns any caravan into a cosy home. However, trapped air can quickly leave your water and radiators cold and aging fluid can turn acidic, quietly damaging internal components.
As factory-trained Alde specialists, Pulse Compliance Testing uses professional flushing equipment to clear air pockets and replace old fluid quickly and accurately, without relying on guesswork. Mike's background is in commercial boilers, hydronic plant and control systems - essentially what an Alde is - so control panel repairs and red or blue fail faults are familiar territory.
We refill your system with approved long-life fluid and test every component, ensuring your heating and water systems stays warm, reliable, and protected for the long haul.

Workshop, mobile visits and Heatport installation
The Middleton workshop holds three or four caravans at a time, and that is where most motorhome boiler servicing belongs, with the parts, power and space for a full strip-down.
Mobile visits across Canterbury suit vans that cannot be moved, especially if you live in yours full-time; travel costs for longer trips are agreed in advance. Breakdowns are usually seen the next day, medium jobs take about two weeks, and weekend or after-hours work is by appointment.
Diesel heater installation can be booked through us as a Heatport installer, with a certificate issued once work is complete. Rental fleet clients often add portable appliance testing.

Common faults are poor performance, hot water only or no heating at all. Hot water only usually means the heating circuit has dropped out while the unit continues doing part of its job.
Old heating fluid can turn acidic over time. Automotive coolant not approved for the system can cause corrosion or blockages, so approved Alde fluid is important.
Common components are held here or with a Christchurch importer. Other parts can come from Sweden in roughly 72 hours, depending on availability and the repair required.
Workshop service is preferred for larger Alde work because there is room, power and parts available. Mobile visits across Canterbury can be arranged when a van cannot easily be moved.
