A Guide to Preparing Your Motorhome Heating System for Winter

One of the joys of owning a motorhome is being able to get away in the winter months.

But keeping warm – and making sure the water in the heating system doesn’t freeze – are key priorities when the mercury dips.

As winter approaches, ensuring your motorhome’s heating system is ready for the colder months is essential for comfort and reliability. This guide covers the preparation of both the motorhome boiler and combi heater, helping you make the most of winter travel without compromising warmth or efficiency.

Preparing Your Motorhome Boiler for Winter

Frost damage is not covered by boiler warranties, motorhome warranty or most insurers, and with Alde, the heating system manufacturer for motorhomes and caravans, saying boiler repairs can cost an average of £1,000, it’s important to act.

1. Thorough Inspection and Cleaning
   Begin by visually inspecting the boiler for any signs of wear or corrosion. Clean out any dust or debris that may have accumulated, especially around the air intake areas and any ventilation openings, to maintain optimal airflow.
2. Drain the System Properly
   Before winter, it’s essential to drain the boiler system if you anticipate freezing temperatures. This step prevents water from freezing within the system, which can cause damage to pipes and fittings. Ensure you drain fully to avoid trapped water, which could lead to costly repairs.
3. Check Antifreeze Levels
   If your boiler system uses antifreeze, verify the levels and top them up as necessary. This provides added protection against freezing and reduces the risk of damage to your system.
4. Inspect Connections and Hoses
   Inspect all connections, pipes, and hoses for leaks or wear. If you detect any issues, address them promptly to prevent more significant problems during winter.

If you are using your motorhome in the coldest months, it’s wise to invest in arctic or winter packs, if your vehicle manufacturer provides them. These include Truma EisEx regulator defroster, which prevents the bulkhead regulator from freezing, and FrostControl, which automatically dumps fresh water if the temperature drops below 4C, as well as heated onboard water tanks.

If they aren’t provided as standard, the arctic or winter packs can also include underfloor heating or heated mats. And even better? These can be retrofitted, so you could be enjoying winter breaks without the risk of boiler breakdown in no time!

Using Your Combi-Heater in Winter

The combi heater plays a critical role in keeping your motorhome comfortable during winter. Issues with heating can lead to chilly nights and costly repairs, especially if systems are overworked or improperly maintained. By managing settings, performing regular maintenance, and ensuring proper ventilation, you can keep your heater running smoothly and avoid unexpected breakdowns or fuel inefficiency.

1. Optimal Temperature Settings
   Setting the combi heater at an optimal temperature conserves energy and ensures comfort. Adjust the thermostat to find a balance that keeps the interior warm without using excessive fuel or electricity. For especially cold days, consider preheating the motorhome to reduce initial strain on the heater.
2. Regular Maintenance and Cleaning
   Like the boiler, your combi heater needs periodic maintenance. Clean the fan and air outlets, and remove any dust around the system to ensure even heat distribution and efficiency. Regular cleaning also prevents overheating and keeps the system running quietly.
3. Ventilation Tips
   Good ventilation is crucial when using heating systems in enclosed spaces. Ensure vents are clear and the exhaust system is unobstructed. This prevents the build-up of condensation and improves air quality within your motorhome.
4. Fuel Type and Efficiency
   Depending on your combi heater’s fuel type, ensure you have enough supply for extended trips and cold weather. Regularly monitor fuel levels and opt for more efficient fuel sources, if possible, to maintain performance without compromising cost-efficiency.
