Underfloor electric heating stuck on!

[Vikkimartin43]

Hi
We’ve just bought a Hobby Prestige 720 UKFE
It has electric underfloor heating that appears to be stuck on constant, we’ve turned it off at the control panel and on the myconnect AP yet the floor is constantly warm. Any ideas as to get this off as we are melting !! 🫣

Many thanks

Hi Vikki. Welcome,

Sorry, I have no clue.

There should be a tap that switches off the underfloor heating. No idea where it is however normally there should be no necessity to switch off the tap. I am only going by our Elddis switch had underfloor heating and heating system was ALDE.

The OP clearly stated it was electric underfloor heating, so it should have a switch, not a gas tap.

Being a Hobby caravan, I wonder if it was purchased in the UK or elsewhere, as this may affect what support you can expect from the seller.

However I'm not familiar with this type of heating so I can't give focused help. But if you can't turn it "off" it is clearly malfunctioning, and potentially dangerous. Have you read the caravans handbook or asked the seller about it?

If its been built for the UK market, it should have a a fused spur isolator switch so the system can be isolated. Removing the fuse should be easy and stop the heating. The system may have its own Miniature Circuit Breaker (MCB) in the mains electrical consumer unit. or it might share its MCB with some other mains circuits or appliances in the caravan. switching the MCB off should s top the heating, but it may also prevent some other appliances from working.

If you have only just purchased the caravan in the UK, and it was a private sale, then you have very few legal rights to get it repaired by the seller, but if its was purchased from a UK dealer then you should look up your rights given to you by the Consumer Rights Act as the dealer has certain liabilities to you, to repair faulty goods.

The EU has some very similar "rights" . Check up how they apply to the country you purchased the caravan in.

Could you work out where the fuse is and pull it as a temp solution then get an expert, who has experience with it, to take a look?

No one mentioned a gas tap, but there is a tap to switch off the heating fluid to the underfloor heating on some caravans! If an ALDE system the water is heated in a "jacket". If the ALDE system, removing any fuse may have an effect on the hot water heating.

Read the second sentence in the original post!!
It reads "it has electric underfloor heating!"
So its reasonable to assume that it has electric heating elements like an electric blanket and not any sort of fluid to turn off via any sort of tap.

We had electric underfloor heating. The water wass heated in a jacket and the hot water flows around the pipes under the floor. The hot water and heating element were one and the same. I doubt if it will have an elements just for underfloor heating as that will require an additional boiler.

Whilst this is AI and not definitive

Seems the OP may well have a liquid under floor heating system powered by both gas and electricity
I suspect Buckman may well be correct😉

Here’s an owners guide which might be helpful if you haven’t already got one.

There’s a surprise. Hobby use both wet and dry depending on the options chosen at sale time. Hopefully the details will help the OP

Well done Buckman

Thanks OC for finding the user manual. On page 129, it describes a 24V underfloor heating system. We have to presume this is the system Viki is referring to. According to the booklet this heating has its own transformer that runs from the 230V mains supply. What it doesn't say is how to control the heating.

On Page 97 there is a diagram of the "Electrical Distribution Board" On the left hand side near the top is item "35 Floor Heating"

At the top of page 61, there is a illustration of a control panel and there is an icon showing two foot prints above three wriggly arrows.

On Page 64 there is a description of how to control the under floor heating with further references on pages:-
66,
84
96
97
129
133 in relation to a wet system
146 regarding the weight of the system.
