Quick answer: ProWarm is a sensible mid-range choice if you want both electric and water-based underfloor heating options from one brand. Its 2mm electric cable, clear installation guidance, free technical support and conditional lifetime warranty on electric mats, cables and thermostats are useful strengths. The range is broad, but the better water-system options involve more specification and are less suited to a quick bathroom installation.
ProWarm at a glance
ProWarm is a UK-focused underfloor heating brand with electric products for individual rooms and water-based kits for larger projects. Its electric range includes sticky mesh mats, loose cable, a foil mat and the ProGrid+ system for cable layouts. The wet range includes conventional in-screed systems, multi-room manifolds and low-profile overlay systems.
That makes it broader than some single-room electric specialists, although ProWarm doesn't present the same polished smart-home ecosystem as Warmup. The practical question is whether its products suit your floor build-up and installation team, not whether the brand wins a generic specification chart.

What is ProWarm?
ProWarm sells directly through its own website and also supplies products through retailers and trade partners. Its range covers the two main underfloor heating routes described in our electric underfloor heating guide: resistance cable warms the floor directly, while water-based systems circulate heated water through pipes embedded in a floor build-up.
The best-known part of the range is the electric mat kit. The water products are more substantial than a simple bathroom supplier would offer, including single-room, multi-room, high-output and low-profile systems. If you're still deciding between technologies, our electric versus water underfloor heating guide sets out the running-cost and installation differences.
Electric mats: the main reason to consider ProWarm
ProWarm's standard electric mat uses a 2mm twin-conductor cable fixed to fibreglass mesh. The cable can be repositioned at the mesh, although the heating element itself must never be cut or damaged. It's intended for floors covered with tile, stone, ceramic and similar finishes.
Three outputs are available:
- 100W/m²: ProWarm describes this as a primary option for new builds or a secondary heat source in older properties.
- 150W/m²: The brand's best-selling output, aimed at bathrooms, kitchens and living areas using it as the main source of heat.
- 200W/m²: The higher-output option for spaces with greater heat loss. ProWarm states it can provide a 25% faster warm-up than the 150W mat, although the result still depends on the floor build-up, insulation, floor covering and controls.
The difference between the three is more than a label. A higher output can produce more heat per square metre and respond faster, but it also needs an appropriate circuit, thermostat and design. Don't choose 200W simply because it sounds more powerful. The room, floor covering and heat-loss calculation need to support it.
A 2mm cable also helps where floor depth is tight. It reduces the build-up needed to cover the mat with adhesive and finish, although the mat still needs a suitable base and, in many installations, insulation. Our underfloor heating installation guide explains why that preparation matters.
Loose cable, ProGrid+ and foil mats
Not every room is a clean rectangle. A loose cable system gives the installer freedom to work around an island, bath, wardrobe or awkward corner. The cable is secured at calculated intervals, then covered with screed, levelling compound or tile adhesive. The choice of spacing affects output, so the layout must be planned before installation.
ProWarm's loose cable is a 10W per linear metre product. Its final output changes with the spacing used. That makes a proper layout essential. It is more flexible than a mat, but there is less tolerance for guesswork.
The ProGrid+ system gives loose cable some of the convenience of a mat. Cable sits in a pre-spaced grid, so the installer doesn't need to set every run by hand. ProWarm specifies this mat for 150W cable, or Warmup DCM-PRO cable. It's a sensible option for a shaped room when the fixed mesh of a traditional mat won't work.
ProWarm also sells a foil-backed mat for wood, vinyl and carpet applications. It isn't a generic do-anything mat. The chosen floor covering, installation method and temperature limits still apply. Check the underfloor heating flooring guide before ordering a system for timber or LVT.
ProWarm thermostats
The control choice is broader than you might expect from a value-focused heating brand.
The Pro Digital Thermostat is a slimline programmable model. It supports floor, air or combined sensing, comes with a remote floor probe, has four daily set points and includes holiday and manual modes. Its maximum load is 16A at 230V AC.
The ProTouch-V2 is a touchscreen thermostat for either electric or water systems. It adds modes such as open-window detection and offers both air and floor sensing. The ProTouch-E WiFi model provides app control and a seven-day programme for electric systems. It can also work through the Smartlife SmartLiving app, so check current app support before ordering.
ProWarm also sells wired and wireless water-system controls, including the ProTouch-W. Its published specification says the ProTouch-W is intended for 2.4GHz routers, and a floor probe is sold separately. That's a detail worth checking before you finalise a multi-room installation.
None of these controls turns ProWarm into a dedicated smart-home platform. They cover scheduling, remote control and floor-temperature protection, which is usually enough for a single room. If your main reason for choosing UFH is detailed energy monitoring, open protocols or deeper integration with other smart devices, compare the controls carefully rather than assuming brand compatibility.
Water-based ProWarm systems
ProWarm's conventional water kits use 16mm Pert-Al-Pert pipe with an aluminium oxygen barrier. The company's product pages identify the pipe as WRAS approved and describe it as suitable for the Water Fittings Regulations and Scottish Byelaws.
Single-room and multi-room packages can include a stainless steel manifold, adjustable flow meters, edge insulation, pipe tools and a Grundfos temperature-control or pump and mixing unit, depending on size. Larger kits add room thermostats, a wiring centre and actuators.
ProWarm also offers LoFlo overlay systems. The 18mm version uses 12mm pipe at 150mm centres. Other LoFlo Lite options use 16mm pipe in 16mm or 20mm panels. These products suit renovations where raising or excavating the existing floor would be disruptive. The trade-off is added floor height and the need to select a compatible floor build-up.
For a whole-house project, start with a room-by-room design rather than ordering by total floor area. Our underfloor heating design and planning guide explains why zones, pipe routes and manifold capacity need to be considered together.
Warranty, CableSafe and the small print
ProWarm's headline lifetime warranty is one of the brand's strongest selling points, but it isn't unconditional. Its registration page says electric mats, cables and thermostats must be installed by an Approved Electrician, installed in line with the manufacturer's guidance and relevant electrical requirements, and registered within 28 days of completion. If those conditions aren't met, the lifetime cover may not apply.
CableSafe is the other useful safeguard. ProWarm says it will replace an electric cable or mat accidentally damaged during installation, subject to its terms and conditions. The cover isn't a substitute for care. Read the current guarantee before starting work, keep the invoice and complete the required registration as soon as the installation is finished.
Water-system component guarantees differ by component, so don't assume every part carries the same lifetime term. Ask the supplier for the current schedule that applies to the exact kit and installation date.
Installation and support
ProWarm's products are accessible to experienced DIY installers, but "easy to install" doesn't mean care-free. Electric work, fixed wiring and Part P notifications fall within the legal and safety framework in England, Wales or Northern Ireland. Scotland has its own electrical installation requirements. A competent installer should handle the circuit, thermostat connection, protective measures, floor probe and testing.
For a mat, the sequence is straightforward: prepare the subfloor, check the mat layout, secure the sensor conduit, install the mat without damaging the cable, cover it with compatible adhesive or screed, allow the material to cure and commission the controls. The CableSafe scheme helps with accidental cable damage, but it can't rescue a poorly planned layout.
The ProWarm technical support team is a genuine advantage when a room is unusual or an installer wants to confirm thermostat settings and floor-sensor placement. Record the advice you receive if the installation is non-standard. If something later fails, the product details, installation method and commissioning record will matter.
ProWarm vs Fastwarm and Warmup
ProWarm vs Fastwarm: Both sell electric and water systems at a similar broad market level. Fastwarm's offering has a strong online and design-service identity, while ProWarm has a wider selection of electric formats, more water-system choices and the conditional lifetime warranty and CableSafe scheme. Compare the exact mat, thermostat, controls and installation terms rather than choosing from brand reputation alone.
ProWarm vs Warmup: Warmup is the stronger choice when smart-home control and established control options are the priority. ProWarm makes more sense when you want a capable 2mm mat, several water-system formats, installer support and a long conditional warranty at a mid-range price.
Our wider UK underfloor heating brand guide covers more of the alternatives.
Who should choose ProWarm?
ProWarm fits these projects well:
- A bathroom, kitchen or living room using a 100W, 150W or 200W electric mat
- An irregular room where loose cable or ProGrid+ gives a better layout
- A timber, vinyl or carpet floor covered by a specified foil system
- A new build or large renovation needing conventional in-screed water heating
- A retrofit that needs a low-profile water system without deep floor excavation
- A buyer who values free technical support and conditional lifetime cover
Look elsewhere if you want a premium smart-home control platform as the main reason to buy, or you expect a complete wet system to be as simple to install as an electric mat. It isn't. Wet systems need correct hydraulic design, a suitable heat source, manifold balancing, controls and commissioning.
Verdict
ProWarm is a credible all-rounder rather than a specialist with one standout trick. The standard electric mat uses a useful 2mm cable and comes in three outputs. ProGrid+ and the foil system cover awkward layouts and non-tile floors. The water range includes conventional, multi-room, high-output and low-profile options, so the brand can serve both a single bathroom and a larger renovation.
The catch is that the strongest headline claims need close reading. The lifetime electric warranty depends on approved installation and timely registration. Water guarantees vary by component. WiFi controls need the correct network, and some floor probes or accessories are separate.
If those conditions fit your project, ProWarm is worth putting on a shortlist. Choose the system by floor build-up, heat loss, controls and installer competence, not by the lifetime headline alone.
