UNDERFLOOR HEATING GUIDE Bringing you the best underfloor heating in South Australia for 30 years. Introduction to Underfloor Heating Due to its supreme level of comfort and great heating efficiency, underfloor heating has become a popular way to heat Australian homes. The feeling of well-being is something we all long for. Feeling warm and comfortable in our homes helps maintain the feeling of well-being and promotes good health. There are numerous ways to experience warmth but only a few that guarantee real comfort. Not only that, hydronic underfloor heating is a worthwhile investment that significantly lower your energy bills. Radiant energy emitted by the floor is partly reflected by each surface and partly absorbed. Where it is absorbed, that surface becomes a secondary emitter. After a while, all surfaces become secondary emitters. Furnishings themselves radiate energy and the room becomes evenly and uniformly warmed. The energy and heat reaches into every corner of the room―no cold spots, no hot ceilings and no cold feet. Sunray has been a leading retailer and installer of hydronic heating systems in South Australia for 3o years. We only use quality components and can assure you of a hydronic system that will provide many years of economical comfort and service. This guide offers information on the different underfloor heating methods and solutions, system components, zone options, combination systems and heat sources available. Say goodbye to dust, ducts and noisy fans.

MINITEC SYSTEM (SHALLOW SCREED) sunraycomfort.com.au 3 The Minitec System installations are designed for renovations or retrofi tting of underfloor heating on an existing building. A thin, rigid plastic sheet is placed on top of existing flooring and the pipework is then laid within. Raised knuckles allow for easy placement of pipework making the installation quick and easy. After pipework is laid, a self levelling compound is poured on top, to a height just over the knuckles. The perforation in the knuckles ensure perfect adhesion of levelling compound to the base level below. Due to the minimal height of the panel, the shallow depth method means the floor level is only raised around 15mm (plus flooring). 6 Underfloor Heating Methods & Solutions (CONTINUED) SUSPENDED FLOOR This method of underfloor heating is facilitated by securing a long, thin sheet of Aluminium called ‘Heat Emission Plate’, between floor joists, with floor boards laid directly on top.
