TG Builders Merchants’ focus is to protect our customers and provide the very best solutions for all aspects of your build. In order to achieve this we have partnered with the leading supplier of Renewable, Ventilation and Underfloor Heating Solutions.

As part of their offering, we will supply a full bespoke UFH design which carries all the technical information needed such as the maximum pressure loss, flow quantity, water content and heating output. Each project is treated separately, and our goal is to ensure we give you a system that is able to heat the space with as low a flow temperature as possible maximising the system efficiency.

We only use reputable suppliers for our products and can offer a full UFH System that includes all manifolds, pumps, pipe, clips, room thermostats & wiring boxes. We can also offer all the floor preparation products such as smoothing compounds, primers, tile adhesives & decoupling layers. To finish the job we also supply LVT flooring should that be required.

Whilst many suppliers offer similar, off the shelf systems, we have assembled a system of products which rely on its guaranteed compatibility within the product installation. All products have been tested thoroughly to ensure the components complement each other perfectly. For our retrofit systems we know the primer works with the adhesive, the adhesive works with the XPS boards, the smoothing compounds work with the boards, and so on. As a result we can count on the products giving the end user a trouble free floor & UFH system!

Our manifolds use cutting-edge technology and are manufactured by Danfoss, one of the leading names worldwide. They have an inbuilt presetting function which uses hydronic balancing to ensure the correct amount of water will be distributed to the right rooms. This can help improve overall system efficiency by up to 20% by balancing the temperature across the floor and reducing the risk of overserving or underserving the UFH pipe circuit.
