DosaFil Residential Technologies – sister company of SolidTek Ltd. (market leaders in the design and manufacture of formulated solid chemical treatments for various markets) has made significant strides since the launch of its innovative and sustainable SOLID chemical system conditioning range for residential heating and plumbing in 2023.

The last 3 years have been quite a journey as they navigated the challenges of introducing a groundbreaking product that is unprecedented in the residential heating sector.

Extensive behind the scenes efforts have been dedicated to promoting the advantages of the SOLID range, which includes cleaners, inhibitors, and biocides, in both the UK and European boiler and low temperature air source markets.  OEMs to end users are now starting to recognise the clear financial and sustainable benefits of proactive solid chemical solutions vs. traditional liquid alternatives.

UK Sole Distributor:

In an exciting development for 2026, DosaFil Residential Technologies has appointed Roth UK as the sole distributor for its SOLID chemical system conditioning range and will manage all UK product inquiries and sales (www.roth-uk.com). Roth UK, part of Global player Roth industries brings over 75 years of experience in the manufacturer of water management and distribution products. The UK division focuses their expertise on the design and supply of UFH products and technical services to drive the growth for low temperature heating and sustainable energy solutions.

As part of this strategic journey Roth has seen the huge benefits of using a solid water treatment product as part of its best-in-class underfloor heating and cooling total system solutions. Successful chemical treatment has been applied to both new build for pro-active system protection and older residential cleaning projects to restore the system as close as possible to the original operational design and efficiency status.

Roths General Manager Graham Moore says:

“We’re delighted to be appointed sole distributor in the UK, and we’re excited by this partnership. We’re convinced by the benefits that the DosaFil Residential products offer us and our customers, and we’re committed to providing the very best in innovation as part of the systems we supply. DosaFil Residential’s range of SOLID cleaners, inhibitors and biocides gives us the portfolio of products we need to maintain the quality of the water circulating in our underfloor heating systems and associated heat source equipment – it’s quickly become a vital part of the overall system solutions we offer our clients.”

European Sole Distributors:

And the story continues to unfold as DosaFil Residential is making significant strides into the European market this year, launching its product range through a selection of carefully chosen sole distributors who align with their commitment to innovation and sustainability across the Czech Republic, Slovakia and Nordic regions.

In Norway, DosaFil Nordics has been appointed as the exclusive distributor for the Nordic region, which includes Norway, Denmark, Finland, Sweden, Iceland and the Faroe Islands.

To date, the Norwegian market has been the primary driver, supported by regulatory changes related to system protection and condition monitoring. To maximise this opportunity, DosaFil Nordics has leveraged Roth Nordic’s strong market presence by appointing them as the sole partner to drive this exciting growth potential.

WTResidential management says:

“Modern heating and cooling systems are becoming increasingly sophisticated, yet water quality is often overlooked. Through our partnership with DosaFil Residential, we can offer plumbers and service professionals innovative solid chemical solutions that simplify dosing, improve sustainability and help protect system performance throughout its lifecycle.”

What does the DosaFil Residential product range offer?

It’s little wonder that multiple distributors want to add this innovative product range to their portfolio – after all it’s a solid alternative to the standard liquid options and offers a more sustainable approach that has a string of benefits that liquid products simply cannot match. In comparison to traditional liquid alternatives, the range of solid products are small and compact – and much easier to store in installers vans and move around site. They’re lightweight ranging from just 20g-90g and these solid products eliminate the need for the millions of plastic bottles which are currently finding their way to landfill every year.

The solid product range meets all the standards and guidelines that currently exist in the marketplace whilst offering a raft of benefits over liquid solutions. The range consists of solid inhibitor, solid cleaner, solid heavy duty cleaner and solid biocide. By offering active ingredients in a solid paste format, these products are not only lighter and safer to handle but also eliminate the risks of leakage and spillage, all while avoiding plastic waste.

Multiple customers have reported success with the solid chemicals and dosing devices that suggest that the result of the solid chemical approach is in all cases as effective as the traditional liquid chemical approach and in many cases, significantly better.

Steve Crick (MD) and Chris Harrison (Technical Director) of DosaFil Residential Technologies say:

“The past 3 years have been incredibly hard work, and we are delighted to now be in partnership with several high-profile distributors who share the same vision as us. These carefully selected partners appreciate the uniqueness and innovation of our product range, recognising its sustainable benefits for both users and end customers. They understand that in this ever-changing residential heating and plumbing landscape, these products are not only truly transformative but offer real practical solutions”.
