The ProWarm™ Water Underfloor Heating Multi Room Systems are the ideal choice for homeowners and tradesmen looking to install a premium branded water underfloor heating kit. These systems provide efficient and comfortable heating for your entire home, ensuring a cozy and inviting atmosphere.
This multi-room water underfloor heating kit includes all the necessary pipe and fittings to cover your chosen zone size, allowing you to create a customized heating solution tailored to your specific needs. Whether you have a small or large space to heat, this comprehensive kit ensures a hassle-free installation process.
Note: ProWarm™ Water Underfloor Heating kits feature water temperature control, which is an essential feature to consider. Be cautious of systems without this facility. ProWarm™ only uses high-quality European Standard Pex-Al-HDPE pipe. The aluminium layer acts as an oxygen barrier, preventing oxygen diffusion through the polymer matrix and protecting the metal components in the system from corrosion.
Below are examples of all the products that could be included in your ProWarm™ Water Underfloor Heating Kit. To find the exact manifold size and pipe length for your chosen kit, please refer to our handy kit content comparison table below.
