With these systems the pipes are placed directly beneath the floor surface, whether timber, tiles, stone, marble or carpet. As the pipes are so close to the surface, these systems heat rooms slightly faster than slab or screed systems. But they are more fragile and susceptible to damage.

Slab heating is where the ‘PEX” pipes are laid within the concrete slab itself. This system is therefore only suitable for new builds or major renovations where a new slab is to be laid.

The MicroHeat CFEWH Single Phase and Three Phase Water Heating products can be used in underfloor hydronic heating systems. The MicroHeat Electric instantaneous solution is compact, requires no venting and is small with an A4 footprint. The unit is installed inside any recess inside the home,  close to the actual floor that’s needed to be heated, ensuring the lowest amount of water required.  It provides accurate temperature control that delivers the temperature required in the reticulated circuit by digitally controlling the power accordingly, ensuring a safe and reliable, zoned hydronic system that delivers a market leading energy efficient solution for continuous water heating for your underfloor system.

With in-screed hydronic systems the pipes are placed on top of a waterproofing membrane and beneath a layer of screed (a sand and cement mix that is used to level the floor). The screed is poured directly over the coils, encasing and protecting them.

Thinking of renovating and want to install underfloor heating? The Uponor Minitec underfloor heating system is ideal for renovation projects.  It can easily be laid on existing screed, timber or tiles, has a total build height of only 15mm and has a fast reaction time so the floor surfaces can start to feel warm within minutes. The Minitec system can be easily customised to fit around obstacles and the desired floor finish can simply be lay on top, leading to a fast installation.

The boiler used for heating the water can be powered using one of several energy efficient and environmentally means. The most common is via natural gas or LPG, or you can also use an electric heat pump to heat the water. Perhaps the most efficient way of powering the boiler is by using solar energy but you may have to install a gas or heat pump backup for days that are cloudy.

There are a number of energy sources and systems  you can use to heat your water for your underfloor heating, including natural gas or LPG boilers, electric air to water heat pumps, wood pellet boilers, a diesel boiler or electric boiler.

The most essential element to any underfloor heating system is the pipes, as a faulty pipe can lead to leaks or corrosion. Most underfloor systems now use a PEX (cross-linked polyethylene) pipe as they are flexible, won’t corrode, don’t burst in freezing conditions and are easier to install. This Pex-A pipe supplied by Hunt Heating is the most flexible PEX on the market allowing for the tightest bend radius and less likelihood of kinking.

Australian Hydronic Heating and Cooling are specialists in installing and maintaining hydronic heating and cooling systems throughout Australia, from underfloor heating to radiators.

When laying slab underfloor heating using a pipe positioning board helps create a thermal break between the slab and the screed which means you are only heating up the secondary layer of screed. This increases efficiency as it reduces the time it takes to heat up. The Hunt Heating pipe positioning board is a market leading pre-formed panel with an R 1.0 value.

The ‘PEX’ Pipe used under the slab which transfers the heated water has been especially designed to prevent corrosion, and is secured prior to the pouring of the slab, to either the mesh or the reinforcing steel rods. To avoid loss of heat into the earth, insulation can be first installed before any of this work begins.

A manifold is central to your underfloor heating system, and and is used to distribute the water through. It provides a central place to connect both your supply and return lines. Supply water from the heat source enters the manifold and circulates hot water throughout the system. This Hunt Heating manifold is developed and designed with control valves for every circuit, lower installation depth and the ultimate in versatility.

The same ‘PEX” pipe is installed and allowances for insulation, pipe diameter and space taken into consideration. The pipe is secured by pins to insulation foam and where necessary notched batons which allow the pipe movement across the floor. The heating pipe is normally installed, before the floors are laid.

In-screed installations have a faster response time than in concrete slab installations, as it is closer to the floor surface. The same ‘PEX’ pipe is used but the method of securing it is by either pins attached to insulation foam or clipped to wire mesh. In addition the screed should be reinforced.

Australian Hydronic Heating and Cooling also provide installation services for commercial projects, large or small. The images below are from a recent project where we installed underfloor heating for the Masina Ice Cream factory being built in Marrickville, NSW.

The water that is used to heat your underfloor slab in winter can also be cooled to cool your room in summer. With the addition of a chiller, the cooled water is pumped through the same underfloor slab as used for your heating system, avoiding the need for two expensive systems to heat and cool your home. Find out more …

The heat from the water warms up the slab first and then radiates into the room above. It can take anything between 24 to 48 hours to realise any benefit depending on the thickness of the cover which acts as form of storage.

A hydronic system simply heats water and moves it through sealed pipes throughout the home. The pipes often feed into radiators but the same principal can be used to heat floors with the pipes installed under the floors.

Running costs are a key consideration and one which can be challenging to answer due to the variability in types of fuels and prices. Actual cost of heating will depend on the area heated, running time, thermostat settings, house insulation, energy tariffs and the local climate. The costing graph below is based on the following typical heat load.
