At Overeem Hydronic Heating, we offer a great range of heat source options to perfectly suit you and your project.

The heat source is the heart of your hydronic system. There are many factors to consider when choosing a heat source, such as space, amount of input required and running costs. We have completed a range of installations with various heat sources for our clients. We will take the time with you to figure out which option is best for your installation, circumstances and needs.

Up-Front Cost vs. Running Costs

Cost is always a big factor in choosing a heat source, especially due to the large variations in up-front cost. Often this is compounded by the fact there are multiple solutions that will work for your system. For some systems, the up-front cost may be low but running costs extremely high, and vice-versa.

Availability of Fuel

Although a great fuel source for many reasons, mains Natural Gas is not available in many areas of Tasmania.Many rural properties have good accessibility to wood stocks. Wood fired hydronic boilers are a very effective solution.Solar thermal, air sourced heat pumps & geothermal do not require an external fuel source.

External Noise

Whilst a hydronic system is silent inside the house, spare a thought for your neighbours when choosing an air-sourced heat pump or geothermal heat pump as these both have compressors that can make noise.Thoughtful placement of the compressor can often overcome this issue.

Level of User Input

Whilst cheap to run, some heat sources require more input than others.Wood boilers & pellet heaters for example must be refueled, but gas boilers, heat pumps, solar & geo thermal systems don't.

Space Requirements

Sometimes the available space may dictate which heat source can be used for an installation. Some options such as solar thermal require a large amount of space. If there is insufficient space a more compact solution such as air-source heat pump might be appropriate.

Air to water heat pumps are a great cost effective solution for heating your water for hydronic heating, especially where gas is not available. Air to water heat pumps are situated outdoors and are perfect for either residential or commercial projects. We prefer the Bosch Compress unit as it's the proven leader in air to water heat pump technology, and perfectly suited to the Tasmanian climate.

Hydronic condensing gas boilers are the most common heat source and are usually the cheapest option to install. Gas boilers are available in both Natural gas and LPG. Natural gas is relatively cheap to run, however availability may be limited. LPG can be expensive, although newer units with improved efficiencies are improving the situation.

Don't panic! Wood boilers are a very common way to provide heat for your hydronic system. Wood boilers are very popular in areas where other energy sources may not be available, or if a client has access to wood as a very low cost fuel. Wood boilers come in many forms, from standard through to wood gasification boilers, we can fine the right boiler to suit you.

Solar thermal is a great way to take advantage of free energy from the sun! Solar thermal can provide your domestic hot water, hydronic hot water, and can even heat your pool. Solar thermal systems are usually installed with either wood burner, gas or air to water heat pump as a backup to provide year-round comfort.

Geothermal heat pumps work in exactly the same way as air sourced heat pumps (the same as you'd find in a reverse cycle air conditioner or air to water hydronic heat pump), except the use the stable temperatures just below the ground to provide heat. Whilst not cheap to install, these systems can offer up to 400% efficiency, so for a client with long term plan this can be an attractive option.
