Hydronic Heating and cooling

What is Hydronic Heating and cooling?

 A Hydronic heating system is a method of heating a home or building with heated water. The heated water passes through a heat emitter that therefore heats the room. The two most common forms of hydronic heating is infloor heating and radiator panel heating. Below you will find an overview on both methods and information as to their installation methods and consideration to make when looking at this form of heating for your home.

Is hydronic heating and cooling efficient?

 A hydronic heating and cooling systems can be very efficient. But this is only true if designed and installed correctly and only when coupled with a truely efficient geoexchange or air to water heat pump that utilises smart controls. By using heat pump technology you are using an efficient electrically driven system that can use onsite renewable power from Solar PV or green power purchased from your electrical retailer. 

What is the best option for me?

  The hydronic heating and cooling option that will suit you best will depend on a number of factors including your location, whether you are building a new home or renovating and the style/ build of your home. Generally if your are building a new home with a concrete slab it makes it a great time to install hydronic infloor heating and if you have an existing home hydronic radiator panels work well to retrofit.

Hydronic Infloor Heating

Hydronic infloor heating consists of a network of special pipework installed in your floor. Warm water is circulated through the pipework letting heat radiate up from the floor surface. Imagine stepping out of bed in the morning and the floor is warm and pleasant and your whole house is comfortable, with hydronic infloor heating this can be a reality.

 

BENEFITS

  • Potential for individual room control so you only have to heat the areas you are utilising.

  • With no fans need to distribute heat there is very low air movement which means low dust circulation and plus for allergy sufferers.

  • The pipework is a sealed system so has low maintenance requirements.

  • These are proven systems that have been tried and tested widely in Australia for a number of years.

  • When coupled to the right heat source (geoexchange or air to water heat pump) hydronic in floor heating can be a very energy efficient way of heating your home or building.

  • Hydronic infloor heating is versatile and works with a wide range of floor types and coverings.

Hydronic Infloor Cooling

Whilst there is a possibility to reverse your heat pump to chill water instead of heat hydronic infloor cooling is not suited to every home. Factors that will dictate whether this is a option for you to explore is dependant on the cooling requirements for your home and your location. We can offer cooling via fan coil units using chilled water if slab cooling is not an option.

Design of infloor heating systems

We don’t do guess work!

We have found that even though we are good at laying pipe nothing will compare to a system installation that is properly and professionally designed.

With every hydronic in floor heating installation we undertake we utilise  the services of REHAU’s top engineers to document and design the floor heating component of the project.

This not only gives us a layout it gives us the correct figures that each floor loop requires as a flow rate setting to match the heat output required + peace of mind.

Hydronic heating floor layout designs create a plan that suits the project.

Materials

Pipework

The pipe we choose to use for our hydronic underfloor heating installations is manufactured by REHAU, a world leader in the manufacture of heating pipe since 1948. The quality heating pipes are made from Cross Linked Polyethylene, with a co-extruded EVAL oxygen diffusion barrier. Cross linking is the process of linking molecules in the polyethylene, giving much improved physical properties. The EVAL Oxygen diffusion barrier completely surrounds the base pipe and prevents the entry of oxygen into the system through the pipework. This significantly reduces the risk of corrosion damage to  ferrous components in the heating system. The EVAL barrier is highly resistant to abrasion and is notch resistant and thus capable of withstanding rough treatment on site. The REHAU pipe we install carries a 25 year manufacturers backed warranty.      

Manifolds

Pipework laid in the floor returns to a central location and connects to what is referred to as a manifold. We utilise Rehau’s quality stainless steel manifolds that as well as being the main distribution point of heated water to your floor pipework also includes flow control so we can adjust the flow of water through each pipe loop to maximise heat output and reduce the amount of energy used. The manifolds only take up a small space and are generally located in a central location in the house like the bottom of a laundry, bedroom or linen cupboard.

Hydronic Radiator Heating

Hydronic radiator heating consists of wall panel radiators hung on the walls in the rooms you would like to heat. Heated water is circulated through the panels letting the heat radiate into the room. Radiators come in many styles and colours and are a great method of retrofitting hydronic heating to an existing home or building.

 

BENEFITS

  • Potential for individual room control so you only have to heat the areas you are utilising.

  • With no fans needed to distribute heat there is very low air movement which means low dust circulation and plus for allergy sufferers.

  • The hydronic radiator system is a sealed system so has low maintenance requirements.

  • These are proven systems that have been tried and tested widely in Australia for a number of years.

  • When coupled to the right heat source (geoexchange or air to water heat pump) hydronic radiator heating can be a very energy efficient way of heating your home or building.
