"We are trusted by the industry to rapidly deliver pre insulated pipe solutions for a wide range of applications - from remote location of a single domestic ASHP to complete district heating schemes serving multiple dwellings"

Lewis Brown, Director Flowsupplies Ltd

"I'd happily recommend Flowsupplies to anyone needing pre-insulated - quality product and fast turnaround.  Much more flexible than other alternatives we've used"

Installer, North Yorkshire

Flowsupplies Project Highlight: Centralised Heating & Hot Water Network for Glamping Site

Flowsupplies delivered a fully integrated heating and hot water network serving 12 glamping pods, all connected to a central plant room. By eliminating the need for individual boilers in each pod, the system significantly reduces the risk of appliance failure and massively reduces ongoing maintenance costs.

Berkshire

"Flowsupplies makes our life easy when it comes to pre-insulated pipe for our ASHP jobs.  Helpful staff and prompt delivery.  Great way to remotely situate a heat pump for aesthetic and noise reasons with negligible heat loss"

Installer, Hampshire
 
"We regularly use pre-insulated on our projects to run heating and hot water for outbuildings from the main house system or enable remote situation of plant rooms.  Flowsupplies offer a reliable service and are always helpful if we have questions.  Not the cheapest but this is a product we bury under peoples homes and gardens - quality is imperative"
 
Developer - Wiltshire
How flexible is ISOFLOW pre-insulated pipe?

Very.  Take our super insulated 32mm double in a 160mm duct - it has a 500mm bend radius that's easy to achieve with one pair of hands.  Designed specifically to reduce bend radius meaning the pipe is simply curved out of the ground - no underground elbows required.  Refer to tech specs for the bend radius for your specific product.

Does the system comply?

Yes.  ISOFLOW pipe has been designed in accordance with BSEN 15632 1,3, cold and DHW potable pipe is also WRAS approved

What's the lead time?

Most sizes 25mm to 63mm are available for next day delivery if ordered before midday.  Above 63mm approx. one week, please call to check the specific product you require.

How good is the heat retention?

Excellent.  Take our 32mm double in a 160mm duct - only 7.7watts per metre heat loss at typical ASHP flow/return temps of 45C/35C.

Do the fittings require special tools?

No.  Our clamp type fittings use a stainless steel bolt - a spanner or socket set is all you need.
