Recommended Extras

We've hand-picked these items because they are a great choice alongside the ThermoSphere Vario EZ Underfloor Heating Cable Kit

Using patented and unique technology in the UK market, the Vario EZ underfloor heating cable kit from Thermosphere is super easy to install, incredibly safe to use and very efficient.

Using TwistedTwin™ technology, the heating cable has a tough fluoropolymer coating on the outside and on the internal conductors, as well as a continuous armoured earth sheath and multi strand twin conductors. In essence, this unique technology makes for a more robust and safe cable that will be longer lasting than others on the market.

And using patented technology, installing will be a breeze. With a high grab adhesive fixing strip, you can easily measure the distance required between the cables using the pre-measurement guide and stick it down ready for the next step of installation.

You can use this kit as a primary heat source depending on your individual requirements and insulation levels. It is recommended to install with a spacing that achieves an output of at least 150W/m²; with at least 80% of your floor covered to ensure a primary source of heat. To work out how much you need, simply work out how many metre squared your space is and use the table below to work out the length of cabling required.

At just 3.5mm thick, you won't need to significantly raise the level of your floor, simply use a layer of 10mm self-levelling compound before laying your chosen floor finish - carpet, laminate, timber of vinyl. If installing underneath tiles, then you can use a layer of flexible tile adhesive instead. And with a lifetime guarantee, you can buy with confidence that this heating system will warm your toes for years to come.

Features:

Heating cable kit to give you flexibility to your installation
Comes with: Vario cable dispenser, Vario fixing strip, factory test certificate and installation guide
Patented high grab adhesive strip allows you to easily measure and install your cable thanks to the pre-marked 10mm increment guide. It also allows you to measure and mark on the substrate.
For primary heating source - you need to space the cable to achieve an output of at least 150W/m2 with at least 80% floor coverage
If you have an older building or low insulation levels, you may need to decrease cable spacing to increase the output to at least 200W/m2
Also suitable to use as a secondary heating source
TwistedTwin™ heating cable is only 3.5mm thick
Safe to use in wet areas
It's recommended to use insulation boards to reduce heat up times and to create a more efficient system. If using for timber substrates, use a coated board. For concrete substrates use an uncoated board - sold separately, see recommended extras.

How Long Will My Delivery Take?

Of the 5,000+ products we offer, around 1,000 lines are ready for immediate dispatch directly from our warehouse - these items are labelled as ‘In Stock’ or ‘Next Day Delivery.’

Other items will show an estimated lead time, such as 2-4 or 3-7 working days, and are ordered on-demand from our brand partners right away. This information is shown on each product page throughout the website, as well as in the basket prior to checkout, and in the checkout process itself.

If desired, you will be able to split your order into multiple deliveries during the checkout if they have different lead times.

Items showing ‘Delivery from [Date]’ are available to pre-order, and will be placed on back-order. There’s no need to worry about double delivery costs: any pre-order products in your basket will be split from your main delivery free of charge, therefore will not hold up your main order. These will be delivered as soon as they arrive in our warehouse.

We are currently seeing reduced accuracy with the stock information we get from our brand partners as well as unexpected delays to stock arriving in the UK. Although we are still meeting the vast majority of these lead times, we advise ordering 'In Stock' items if you are working to tight deadlines. We guarantee that we are doing everything in our power to minimise any delays, but we ask for your understanding about the impacts of Covid-19 and Brexit on our supply chain.

Our sales team are happy to specifically check any products not displaying as 'In Stock' - simply visit our Help Hub for more support and ways to contact our team.

Is Delivery Free of Charge?

Yes, we offer free standard delivery on UK mainland orders, but some area exclusions and surcharges apply*. We also offer premium next day and weekend services on 'In Stock' items from as little as £4.99.
Items that are not available for next day or premium deliveries will display an estimated lead time displayed in working days (Mon-Fri). Please note that when ordering multiple items, the longest estimated lead time shown would apply to the complete order, although we do give you the option of splitting deliveries within the checkout if you would prefer to receive relevant items as quickly as possible via multiple consignments.

* Additional charges will usually apply to some areas of Scotland and Scottish Isles, Channel Islands and Northern Ireland, as well as to some harder-to-reach areas of mainland UK for large or fragile items that are sent by pallet. These charges are displayed within the checkout, before any confirmation is required.

Large Item Orders

Large or bulky items are carefully inspected, and placed securely on a pallet or within a specialist fragile delivery vehicle (unless you're local - then we might use our own vehicles). We'll email you to let you know your goods have left us. Within this dispatch email you'll find everything you need to know about fragile deliveries.

Before delivery, the delivery provider will contact you to arrange a suitable delivery day. Please ensure you leave us the best contact number for yourself.

Please note, the driver will not be able to take the items in to your property, so we recommend that you have able-bodied people at your delivery address to help receive your goods if you have ordered large or heavy items. Palletised deliveries will be offloaded to the nearest kerbside to the delivery address, and will also require able-bodied people to lift these into the property, excluding the driver. The driver will wait for 15 minutes for you to check for any signs of damage. Please notify us of any transit damage either on the delivery note, or if there isn't time to check the items thoroughly upon delivery, then within 48 hours of receipt. This does not affect your statutory rights with regards to manufacturing defects and faults.

Please note: if you arrange a delivery time and you aren't there when the delivery team turn up, there will be a re-delivery charge of £30 payable.

Next Day, Weekend & Time-specific Deliveries

If an item is 'In Stock', you will also be able to choose a number of other delivery options during the checkout.
For our other items that show a delivery estimate, you will not be able to choose next day or timed services. We aim to deliver the item within the advertised timescale.

International Delivery

We can deliver small items (valves, brackets, hooks, heating controls etc.) to most of Europe and internationally. You will be informed if any of the items in your basket are not able to be sent to your country during the checkout process.

If your country is not listed, or if you want to order a larger item, we may still be able to help. Please chat to us via live chat or send us an email.

Can I Collect My Order Instead?

We do offer collections from our Bournemouth warehouse should you need something as quickly as possible and you’re able to travel to us. Just select collection at checkout.

Please note: We'll need 30 minutes from order placement to have everything ready for collection.You'll need to place your (in stock) order before 4pm to collect the same day, and arrive to collect from the warehouse by 4.30pm.

Please collect your items within 7 days or let us know if there is a delay.

Our warehouse address is: 447 Aviation Business Park, Christchurch, BH23 6DS. Open 8am - 5pm.

Returns & Collections

For unwanted items we offer 90 days for a credit note, and 30 days for a refund. Please note that there are a few items we are unable to take back, including some special finish taps and showers, toilet seats that have been opened, and bespoke orders. See our returns and refunds FAQs.

We now offer a collection service for unwanted items. This is particularly useful for fragile, bulky items that are difficult to transport. Unwanted items can be collected at a convenient time and place via our own transport partners. This is a chargeable service - for full details, please see our returns and refunds FAQs.
