46 PROJECT Serengeti’s great plumbing migration By Eamonn Ryan | All images by Eamonn Ryan The plumbing for all 188 apartments at the Whistling Thorns and The Lakes Phase 2, at Serengeti Lifestyle Estate to the east of Johannesburg, which are already sold out, was awarded to Industrial Plumbers, which had previously completed Phase 1. A luxurious development, aesthetics trumped all else. In Phase 1, each of the six-unit complexes was fitted with a 1 000ℓ hot water tank with back-up elements and a 19Kw Kwikot heat pump on the roof. For Phase 2, the design engineers have changed the hot water system due to its unsightliness and the expense of having to hide the roof-based heat pump under a cover. A new supplier, EMS, is consequently doing the hot water system on Phase 2 and designed a system whereby two heat pumps are on the ground floor and nothing on top, using EMS’s own branded pumps. Industrial Plumbers provides the mains connections and EMS simply connects its pumps. Each block of six units has a single 1 000ℓ tank with the heat pump. Industrial Plumber’s Pieter du Toit says the development’s management is gauging the system to see if it provides sufficient hot water supply. Other blocks have eight units for the same system. The reason for this, explains Du Toit, is that the aesthetics of the development trumped other decisions: everything had to be hidden from view. “Consequently, hot water supply may be tight in winter when people traditionally use more hot water. For instance, some of the more upmarket units have free-standing baths which take a lot of water. There are back-up water elements in the tanks to supplement the heat pumps and provide more hot water as needed. But it’s not as energy-efficient as heat pumps. The view of the fairway from one of the more upmarket units. “All the plumbing, except the heat pumps on the roof and the tanks behind the stairwell, is hidden. The ducting was mostly hidden within the columns which join up the two floors and links to the bathrooms.” The more popular units face the golf course fairway and were sold first. Some had dramatic views of the fairway, with glass walls enabling one to have a bath while enjoying an unrestricted view of the green. Phase 2 is at an advanced stage of construction with Industrial Plumbers due to finish on site before the end of the month (September). “We try to work in coordination with the roof Phase 1 is almost complete, and work is shifting to Phase 2. www.plumbingafrica.co.za @plumbingonline @plumbingonline @PlumbingAfricaOnline November 2019 Volume 25 I Number 9
