Swift Group and Truma Heating Grade 3 Test

For the 2014 season the Swift Group has turned that heat up even further by announcing that all its caravans and motorhomes achieve Grade 3 standard in thermal insulation. I am Blair Jacobs, here at Truma HQ to find out more about Swift's drive to raise heating standards even higher.

Transcript of Video: Swift Group and Truma Heating Grade 3 Test

Hello and welcome to Swift TV. Now with more people using their caravans and motorhomes throughout the year, staying warm is becoming an increasingly important consideration. Last year Swift really did turn up the heat as the first manufacturer to install Alde central heating in all caravans and motorhomes from the mid-range upwards.

For the 2014 season the Swift Group has turned that heat up even further by announcing that all its caravans and motorhomes achieve Grade 3 standard in thermal insulation. I am Blair Jacobs, here at Truma HQ to find out more about Swift's drive to raise heating standards even higher.

So let’s go and meet Richard Godber from Truma. Now Richard is going to explain how the Swift Group is the first manufacturer to achieve this important milestone with of course the help of Truma and Alde.

Great to see you, thank you for your time. Let’s first talk about this Grade 3 Thermal Insulation and Heating what exactly is that?

It's a European standard for the motorhome and the caravan, it’s a measure of the thermal and heating qualities of the vehicle. To meet Grade 3, the caravan or motorhome has to go from minus 15oC to plus 20oC within in a 4 hour period and the water system also has to work after that period.

What’s the benefit of Grade 3?

Ultimately it’s to ensure we have the best thermal properties we have available to us which means a much better fuel efficient vehicle, lower fuel costs for the Swift owner.

For Swift and Truma it’s much more than just about getting the Grade, it’s building the best quality and thermally efficient vehicles we can.

So how is Grade 3 achieved?

There are basically two ways of achieving Grade 3. One is with a real life test which is how Truma and Swift prefer to do that, the other is a mathematical equation which some other manufacturers will do. When buying a caravan (or motorhome) it’s always a good idea to check how that Grade 3 was achieved.

How does Truma test for Grade 3?

Along with Alde, we realised that to test our heating systems correctly that we needed to use a cold chamber. The cold chamber that we have here is basically a very large freezer which we can fit into that any motorhome or caravan, so it enables us to do a whole range of vehicles, and at the moment we are just about to test the new Swift Escape so if you would like to take a look at how we do that?

That would be great, I’ll follow you.

So Richard tell me what is happening here.

We have technicians placing (temperature) probes throughout the vehicle. There are 5 probes that are required for the Grade 3 test: that is one in each corner and one in the centre, 1m above the ground from the floor level.

Swift has also requested a further 11 probes to be placed in the vehicle, these are purely for research and development.

Once the probes are in place, the technicians open every window and door on the vehicle, and then turn on the freezer, the temperature drops to minus 15 and the Cold Chamber is kept going overnight to ensure every nook and cranny of the vehicle reaches minus -15oC.

In the morning, the technicians will enter the cold chamber and close all the doors, the windows and the lockers on the Swift Escape. Then with the freezer still running to maintain the exterior at minus 15oC, the Truma heating system is switched on.

The probes are monitored through a display unit in the control room and the data constantly recorded. Truma also take thermal imaging pictures to show the cold and heat zones in the vehicle as it warms up.

So as Richard said all this vehicle needs to do is warm up from minus 15oC to plus 20oC in less than 4 hours, no pressure there then! Let’s see how this Swift Escape gets on.

So Richard , what is the result?

I am delighted to say that the Swift Escape passed the test with flying colours. It achieved +20oC in under 3 hours which is well within the 4hrs allowed and the water system worked perfectly to.

That is fantastic news, thank you for showing us how it all works, very good to see you.

So there we are, even it is sub-zero temperatures outside you can be assured of warmth and comfort on the inside on all Caravans or Motorhomes manufactured by the Swift Group.
