The hotun revolution

 This Small, Simple & Affordable Product Is Going to Revolutionise Plumbing and Architecture as We Know it, we call it  The hotun revolution

The Concept

I developed a product that could accept a discharge from an unvented hot water cylinder PRV and connect it to drain compliantly. I had absolutely no idea how well the idea would catch the imagination of the industry.

The initial concept was simple: Providing a compliant connection from the small unvented cylinder to a local drain. However, our horizons were altered irrevocably when we were approached by Worcester Bosch just three weeks after the launch of this little product.

They invited me to come and have a chat. I spoke with some people from their technical team. They liked the concept so much they accepted it for use with their boilers.

Little did I know that the issue of running a landlocked boiler PRV to drain had been causing issues for boiler manufacturers and installers for some time. Amazingly, hotun hiflo has become that solution!

Making Life Easier for Architects and Planners

But the hotun Dry Trap Tundish isn’t just great for boiler manufacturers and installers. The concept of running the PRV to local drain has untold benefits for architects and planners too. On top of this, it provides a cost-benefit out of all proportion to what is essentially a very simple piece of kit.

Traditionally on projects such as flats and spec office developments, all boiler & cylinder PRVs could only be terminated compliantly either externally to the building, or run down service voids internally to a basement level, where they would each be terminated over an open trapped gulley, they would also have to be individually and carefully labelled to ensure correct identification

This caused no end of hassle for building design engineers and architects. Architects don’t want the external fabric of their buildings unnecessarily festooned with copper pipework. Up till now, his only alternative was to run every individual PRV discharge pipe down the internal of the building. In terms of both labour and material, this process was extremely costly.

How Our Simple Product Fixes an Age-Old Problem

Thanks to the hotun hiflo Dry Trap Tundish, for the very first time, a boiler manufacturer has allowed for this connection to be made internally.

It provides a safe and visible means of discharge within the building envelope. This discharged water can then be run to a local internal drain. The hotun Dry Trap Tundish is a small bit of kit measuring approximately 100 x 60mm. It costs approximately £20 per unit.  But despite this, it can save architects and planners thousands of pounds.

Its inbuilt trap provides the ability to pass water through while preventing odours from the drains back into the building. This means that there is no longer any need to run PRVs externally or to take tortuous paths down service voids to the basement. Instead, it is all contained within the confines of the apartment itself.

Safeguards include margins of error in maximum flow rates. Most boilers will discharge between 14 and 18 litres/min if they run “open bore”, which they normally don’t. The hotun hiflo has a rated capacity of 18 litres/min. Recent UKAS accredited tests prove that hotun hiflo can handle flows of almost 20L/min. What’s more, we’ll soon launch a new product that will take this capacity up to 25 litres/min.

We also provide a safety guard for accessible locations (boilers only). It’s a clear plastic shield that clips over the product. This stops curious fingers from exploring potentially scalding hot discharges from the PRV. We call this hotun shield

The hotun revolution

The hotun range of tundishes is such a game changer that some are calling it “the next Adey MagnaClean”. On top of that, the hotun revolution has opened up a whole new world of possibility for architects and design engineers to explore

Despite being so small, so simple, and so affordable, this disruptive and innovative product is going to make major waves.

hotun hiflo UKAS accreditation tests

RA Tech UK Ltd invests to give our customers the confidence that hotun products perform to the highest levels and now hotun hiflo has UKAS accreditation.

Since its inception, the hotun hiflo dry trap tundish has been and always will be all about regulatory compliance. The recent hotun hiflo UKAS accredition test has established that hotun hiflo can cope with a flow of 18L/min and goes on to flow just under 20L/min

When we first started our hotun journey we knew we had to comply with water and building regulations. To enable our product to be successful, full compliance was essential. Our website identifies all the requirements applicable to unvented water heater installations in question here

Our introductory product, hotun, was, designed to fulfill the role of a convenient, cost effective and simple way of dealing with the Pressure relief valve (PRV) discharge from small (less than 15 liters) unvented hot water heaters.

Routing the discharge to drain via hotun, stops odours coming back up from the waste pipe and also provides a complaint air break to prevent backflow issues. As we found out, small unvented cylinders do not flow much water even when manually opened.

Therefor our original product, hotun, was designed for this and has a rated maximum flow of 12L/min

Soon after its launch, the question from installers asked, was hotun suitable for boiler PRV applications?

One of the UK’s largest boiler manufacturers approached us about the application of hotun on the boiler PRV. Tests showed that hotun could not cope with a full bore flow from a boiler. So we developed hotun hiflo which took the flow volume from 12L/min up to approximately 18L/min

In house testing of hotun products

To establish a “working” maximum flow rate, we carried out extensive in-house testing. The boiler manufacturers did their own testing of hotun hiflo and concurred that it was capable of dealing with the full flow of their products PRV discharge.

Of course, on site D2 pipe configurations (of which we cannot control) could have an effect on flow. We are dealing with a gravity drainage type system and the more convoluted the route the less overall volume it can handle.

Independent testing

NSF International Laboratories, a well know accreditation company, who also carry our WRAS approval tests, carried out the independent tests.

NSF established the test methods to ensure repeatable and verifiable results

They put the product on a calibrated cold water test rig. The installed configuration of pipework  forms the base test and gives comparable results for future like for like product tests . For the results and conclusions please click on the link:

The future

We can now proudly say that hotun hiflo has independently proven to deal with the claimed 18L/m. New, 2nd generation hotun products are in the pipeline and we hope to make an official announcement soon as to their launch date

We will continue to put in further R&D to develop our products and welcome any feedback or thoughts our customers may have about our products
