Top questions

In summer, how do I get hot water without central heating?

Set the desired room temperature to 4 °C below ambient on the control panel.

The central heating will cut out— the heating fluid will not be circulated so the living area will not be heated.

Hot water will still function as normal, and the central heating will cut in if the ambient temperature drops below that set.

What fluid do I top-up my Alde heating system with?

If your heating fluid is magenta in colour you can use an Alde-approved antifreeze product to top up with.

If it is not magenta in colour it is safest to top-up with a cupful or two of deionised water. You will have slightly less protection from frost, corrosion and bacteria, but damage caused by mixing incompatible antifreeze is the bigger risk. Then change the heating fluid as soon as practicable and use an Alde-approved antifreeze.

What antifreeze products are Alde approved?

In the UK, they are:

  1. Alde Premium G13 Antifreeze
  2. Fuchs Maintain Fricofin V50
  3. Comma XStream GG40
  4. VW Genuine Parts G13

These are all available ready to use, pre-mixed with deionised water. Always read the label.

These products all have a 5 year life. Corrosion damage caused by substandard heating fluid is not covered by warranty.

How often should I replace my heating fluid?

Heating fluid using an Alde-approved antifreeze should be replaced after 5 years.

All Alde-approved antifreeze is magenta in colour. If your heating fluid is not magenta in colour, replace it as soon as practicable using an Alde-approved antifreeze product.

Corrosion damage caused by substandard heating fluid is not covered by warranty.

In winter, can I use my central heating even though the fresh water is drained down?

Yes, operate the Alde system normally. No harm will result as there are no electric heating elements in the hot water cylinder.

How do I programme the Night/Day Mode on the control panel?

Most people should set their modes to All, to do the same thing every day, since you can’t set different programmes for each day.

As for the time, it’s best if you imagine a 24 hour clockface.

If you want the room temperature to be warm during the day but cooler when you go to bed at night

Setting control panel to Night Mode only

In this example we set desired temperature on the Main Menu to 22 °C. This is our “normal mode”. We set Night Mode to 17 °C, starting at 22:00 and ending at 06:00 when we get out of bed. At 06:00 the desired temperature will revert to the 22 °C we set on the Main Menu. We do not set Day Mode.

If you go out in the morning and come back later in the day

Setting control panel to Night and Day Mode

Night Mode is set as before but we also use Day Mode. We set Day Mode to 10 °C to keep off the chill, starting at 09:00 when we leave, ending 15:00 when we get back. In the times between Day and Night Mode, the desired temperature reverts to 22 °C.

If your programmes don’t work together

Night and Day Modes conflicting

If you set Night Mode and Day Mode to start/end at exactly the same time, they will conflict. There’s also no reason to set Night Mode and Day Mode back to back. Your programme should have an hour or so in “normal mode” between Night and Day Mode, otherwise you don’t need all three modes.

Finally, don’t forget to set the clock.

Why is my Alde heating noisy now?

Air may have separated from the heating fluid and accumulated in the pipes. Follow the instructions in the manual to bleed air.

If your Alde system is new or has just been serviced, the technicians may have left your 12 V inline circulation pump on Speed 45 for bleeding. This can be noisy. Lower the speed on the pump mounted on the side of the Alde boiler. Speed 23 is ideal for most installations.

Getting started

I'm missing an instruction manual. Where can I find one?

All operating and installation instructions are available to download or print in Manuals. If you don’t know which boiler model you have, try our “What boiler model do I have?” section.

What general maintenance and consumables are there?

The heating fluid is a consumable and will need replacing when its protection expires. Since 2019, UK installers must use an Alde-approved product with 5-year protection from new. If in doubt, replace the heating fluid within the first year.

Seasonally inspect the boiler’s flue hoses. They should be secured, undamaged, and clear of obstructions.

When in constant use, drain off and top-up the fresh water every two weeks to replenish the natural air cushion in the boiler. This can mitigate any hammering from the water pump.

Empty the fresh water over winter.

Safety inspections should be completed on schedule as required by law.

In winter, can I use my central heating even though the fresh water is drained down?

Yes, operate the Alde system normally. No harm will result as there are no electric heating elements in the hot water cylinder.

Can I leave my Alde central heating on a frost protect setting?

Yes. There isn’t a specific “frost protect” setting but if you’re hooked up to 230 V electric power you could leave the system running on 2 kW electric heating at 5 °C on the control panel. Check regularly for signs of condensation and remember to drain down the fresh water.

But be kind to the planet; ask yourself whether you really need to heat an empty caravan or motorhome all winter?

How do I programme the Night/Day Mode on the control panel?

Most people should set their modes to All, to do the same thing every day, since you can’t set different programmes for each day.

As for the time, it’s best if you imagine a 24 hour clockface.

Finally, don’t forget to set the clock.

Remind me, how do I use the Alde control panel?

How quickly should the living area warm up?

That depends on the design and insulation in the vehicle, how much power you’re using for the central heating and of course, how cold it is outside.

In vehicles built in the UK with BS EN1645/6-1 Grade III insulation, from cold, most will reach comfy room temperature within the hour if given sufficient power.

 

How do I get the best performance from my Alde heating system?

  1. Use maximum electric heating and gas heating. This prevents wasted energy and improves heat-up time.
  2. From cold, don’t be tempted to “whack up” the desired room temperature above 22 °C. You will waste energy and won’t improve heat-up time.
  3. Set the desired room temperature to a couple of degrees lower than your comfy t-shirt temperature and wear a gillet or cardie instead. This will save energy.
  4. Compact 3020 owners, if you don’t use the hot water at night, set the system to ignore hot water demand. Another energy saving.
  5. Remember to bleed air from the heating system and ensure the vents in the furniture are unobstructed top and bottom. This improves efficiency.

How much electrical current does the Alde heating system draw?

From 12 V

The system is very dynamic with circulation pump starting and stopping, gas igniting, combustion fan changing speed, etc.. The electronics have a more stable draw. For off-grid planning assume the system will draw around 1 A from 12 VDC power supply whilst active.

Parasitic drainwhen the system is shutdownis about 80 mA.

From 230 V

Although nominally 230 VAC, the UK electrical grid has a higher median voltage so depending on how much power the Alde heating is using that’s roughly:

1 kW = 4.8 A
2 kW = 9.5 A
3 kW = 14.3 A

Hot water

In summer, how do I get hot water without central heating?

Set the desired room temperature to 4 °C below ambient on the control panel.

The central heating will cut out— the heating fluid will not be circulated so the living area will not be heated.

Hot water will still function as normal, and the central heating will cut in if the ambient temperature drops below that set.

In winter, do I need to empty fresh water?

Yes.

Unless your vehicle has a FrostControl and fresh water tank heating. Even if the central heating is left at 22 °C there might be a power cut, for example.

What steriliser should I use in the fresh water?

The Alde boiler has a stainless steel hot water cylinder, so you should use a steriliser product that is compatible with stainless steel.

We recommend Puriclean by Clean Tabs. Always read the label.

In winter, can I use my central heating even though the fresh water is drained down?

Yes, operate the Alde system normally. No harm will result as there are no electric heating elements in the hot water cylinder.

How do I drain down the fresh water in my Alde system?

Find your safety/drain valve. Lift the yellow toggle and water will drain out through the underside of the vehicle. Open all taps, showers, and water outlets.

If you’re draining down for winter, don’t forget to empty your grey water and black waste too.

What fresh water can I use in the Alde system?

Only use palatable drinking water.

Sites in Iberia and the Maghreb may use softened, shock-treated well water or desalinated seawater with high levels of bleach and/or salt that will corrode stainless steel.

It may be labelled as drinking water but if you can’t stomach it, don’t use it in the system either, unless your vehicle is equipped with at least a 4-stage RO water filter or marine watermaker.

The Alde boiler has a stainless steel hot water cylinder

How much hot water does the Alde system produce?

When mixing down to a usable temperature, 12–15 litres of heated water every 30 minutes is normal, equating to a continuous shower of 4–5 minutes with a 3 litre per minute flow rate. The system can be equipped with an Alde TMV3 to reduce wastage when mixing the water.

Cold water below 10 °C will take longer to heat.

If your Compact 3020 system is equipped with an Alde Flow module and connected to mains water, the hot water will be continuous. Take as long as you like to wash your luxuriant locks!

Why is my hot water scalding?

Regulations require stored hot water to be heated to scalding temperature to prevent the growth of legionella, a deadly bacteria.

Some installations are covered by regulations that also require thermostatic mixer valves to be fitted, to mix the hot water down to non-scalding temperature before the outlet. In the UK, touring caravans and motorhomes built for sale to end customers who are private individuals, are not required to fit thermostatic mixer valves.

The Alde TMV3 meets the highest UK standard for care homes, hospitals and nurseries and can be retrofitted by any Alde Service Partner.

Antifreeze/Heating fluid

How much fluid is in the central heating system?

As a rough guide, most caravans and motorhomes hold 10–15 litres, A-class motorhomes and boats 20–25 litres.

What fluid do I top-up my Alde heating system with?

If your heating fluid is magenta in colour you can use an Alde-approved antifreeze product to top up with.

If it is not magenta in colour it is safest to top-up with a cupful or two of deionised water. You will have slightly less protection from frost, corrosion and bacteria, but damage caused by mixing incompatible antifreeze is the bigger risk. Then change the heating fluid as soon as practicable and use an Alde-approved antifreeze.

What should the fluid level be in the expansion tank?

About 1 cm above the Min mark when cool.

As the fluid heats up it will expand towards the Max mark.

What antifreeze products are Alde approved?

In the UK, they are:

  1. Alde Premium G13 Antifreeze
  2. Fuchs Maintain Fricofin V50
  3. Comma XStream GG40
  4. VW Genuine Parts G13

These are all available ready to use, pre-mixed with deionised water. Always read the label.

These products all have a 5 year life. Corrosion damage caused by substandard heating fluid is not covered by warranty.

How do I change the heating fluid?

It’s best to use the British Technique, pushing the old fluid out using either the new fluid or clean water if flushing the system first.

Alde Service Partners can quote you for this work, using their Alde service pump kit and Alde-approved antifreeze. Or why not book in at Alde’s Moosewerks facility in Northants.

 

How often should I replace my heating fluid?

Heating fluid using an Alde-approved antifreeze should be replaced after 5 years.

All Alde-approved antifreeze is magenta in colour. If your heating fluid is not magenta in colour, replace it as soon as practicable using an Alde-approved antifreeze product.

Corrosion damage caused by substandard heating fluid is not covered by warranty.

Why is my Alde heating noisy now?

Air may have separated from the heating fluid and accumulated in the pipes. Follow the instructions in the manual to bleed air.

If your Alde system is new or has just been serviced, the technicians may have left your 12 V inline circulation pump on Speed 45 for bleeding. This can be noisy. Lower the speed on the pump mounted on the side of the Alde boiler. Speed 23 is ideal for most installations.

Gas heating

Can I use my gas heating as I drive along the road?

No.

Even if you have a crash sensor in your gas regulator, you must remember to shutdown the heating system fully before pulling into a fuel station.

If you forget, you will effectively be standing on the forecourt with a lit gas burner.

What LPG fuel systems can I use?

Metal LPG bottles are most versatile. Performance of composite bottles deteriorates more quickly than metal in extreme conditions. Fixed refillable fuel systems are fine but read the filling instructions carefully to avoid flooding your gas lines with liquid gas.

Propane or butane – what type of LPG should I use?

In the UK, use propane (red bottle) from a reputable supplier or Autogas.

Butane (blue bottle) isn’t suitable for use in temperatures below 13 °C (BS 5482 Part 1).

How much gas does the heating system consume?

As a rough guideline, when running on gas in the UK climate, a 6 kg bottle of propane should last all weekend at most times of the year.

The dual-stage gas burner is computer controlled and electric heating can be prioritised (and is by default).

Prospective buyers

What is the power output of the Alde aluminium convectors?

The convectors put out ≈400 W per metre. Doubled up, they put out ≈600 W per metre.

Can copper parts be used in the Alde heating circuit?

No.

If they shed copper particles they may cause galvanic corrosion in the Alde boiler’s aluminum glycol cylinder. Such damage won’t be covered by warranty.

The boiler’s hot water cylinder is stainless steel.

How much fluid is in the central heating system?

As a rough guide, most caravans and motorhomes hold 10–15 litres, A-class motorhomes and boats 20–25 litres.

How much does an Alde system weigh compared to a forced/blown air system?

An Alde system provides both central heating and hot water rather than having two separate systems. But compared to a combined forced air and hot water system, an Alde system in a caravan will weigh about 10 kg more when full.

Which caravan and/or motorhome manufacturers currently fit Alde systems?

Alde systems are fitted into a wide range of models, as shown in our European installed base.

Can I run the Alde heating system on electric only?

Yes. 12 VDC power is used for the heating controls but you need stable 230 VAC power supply for electric heating.

The Alde system can output 1, 2 or 3 kW on electric heating, selectable from the control panel. In the UK with its higher median voltage, that’s a load of roughly 4.8, 9.5 or 14.3 amps.

Bear in mind that most caravans and motorhomes have their insulation tested with gas and electric heating, so electric heating alone won’t be sufficient in all weather. (Gas heating adds another 6 kW of power.)

 

Is Alde heating system a sealed or open-vented heating system?

Alde heating system is an open-vented system. This allows pipework and fittings to be physically thinner and lighter and the circulation pump to be quieter.

(Alde Compact boilers are room-sealed with fan-assisted balanced flues.)

Can I run the Alde heating system when I'm off-grid?

Yes. You’ll need 12 VDC power from the leisure battery for the heating controls and propane for your 6 kW gas heating.

Can I buy products directly from Alde?

Alde distance sells to trade customers only. Contact us to setup a trade account.

All other customers can purchase from our resellers.

Customers booked in for work at our Moosewerks facility in Northants can purchase spare parts and accessories and have them fitted while they wait.

Are touchscreen control panels backwards compatible?

There have been three Alde Compact boiler models: Compact 3000 (19932005), Compact 3010 (20052014), Compact 3020 (2014 to date).

None of their control panels are cross-compatible with each other.

Compact 3010 systems can all be upgraded to a touchscreen control panel with the Colour Touch Upgrade. If upgrading from the slider switch/control knob panel then the Digital Adaptor Lead is also required.

Can I use underfloor heating only to heat my vehicle?

No.

A building has much better insulation all-round than a caravan or motorhome, and doesn’t have gas drop-holes either.

Underfloor heating should feel about the same temperature as the soles of your feet are naturally. Somewhere around 30 °C. Any warmer will be uncomfortable.

So you will still need a smart designed heating circuit, with convectors and radiators to warm up the living area.
