The new hotun sf range has been designed to make installation achievable in just a few seconds, with the addition of industry leading JG Speedfit Technology.
The revolutionary hotun was invented in 2015 by RA Tech Managing Director and experienced plumber, Russell Armstrong, to easily enable installers to discharge unvented water heaters and cylinders Temperature and Pressure Relief Valves, and boiler Pressure Relief Valves, compliantly to a local waste or soil pipe. It also eliminates the risk of odours returning from the foul drain.
Officially accepted for use with boilers and cylinders from the UK’s largest manufacturers, the award-winning hotun dry trap tundish has benefitted from further development. The new range provides a simple solution for boilers, plus small and large unvented cylinders, offering 15mm and 22mm pushfit sizes on the inlet and 22mm compression and 32mm pushfit on the outlet.
All models are WRAS approved and independently tested for flow rate by UKAS test house Kiwa. As well as coping with trickle and low volume flow discharges, the range now boasts flow rates of 16LPM for hotun sf (15/22), 25LPM for the hotun hiflo SF (15/32) and 40LPM on the hotun xlsf 22/32 model, so there will always be a model that will suit a full flow discharge for your application.
Russell Armstrong says: “The hotun is a compact, open-sided tundish that cleverly incorporates a unique and patented in-built non-return valve. It’s an incredibly useful product for any installer to have in their armoury, and the development of the new hotun sf range with push-fit fittings now makes it even quicker and easier for installers to use.”
