Solar Hydronic Heating
When we think of solar we normally imagine panels on our roofs which are used to generate electricity. Solar hydronics, also known as solar thermal, is similar but is used to heat up water directly which can then be used to supply your hot water system or heat up your home.
How does it work?
Why Invest in a Solar Hydronic System?
Australian Hydronic Heating and Cooling, a division of AJ’s Plumbing, are experienced in all hydronic heating systems, and can work with you to select and install the ideal solar hydronic heating system for your home.
ROTEX water and home heating system
ROTEX, now part of the DAIKIN group, is a manufacturer of innovative and environmentally responsible heating systems. Their ROTEX thermal store and ROTEX Solaris solar thermal system combine for both hot water and home heating. Australian Hydronic Heating and Cooling can supply and install a ROTEX system in your home.
The ROTEX thermal store places special emphasis on water hygiene for showering, bathing, cooking or hand washing. The system ensures you have hot water available at the right volume and at the right temperature.
The thermal store system works in conjunction with the ROTEX Solaris solar panels to provide water heating and space heating backup, to be used for pressurised solar and drain-back applications. The Solaris solar panels convert almost all of the shortwave solar radiation into heat through their highly selective coating.
The ROTEX thermal store comes in two versions. The Sanicube Solaris is an ideal addition for an oil or gas condensing boiler. The HybridCube works specifically with a ROTEX air-to-water pump HPSU, designed for low flow temperatures. When either version is combined with Solaris Solar system they provide the highest level of energy efficiency thanks to low heat loses, perfect water hygiene and unlimited hot water.
The ROTEX Solaris is available in two different styles. The Solaris-P is a pressurised solar system which is simple to install and suits all applications and buildings. An additional plate heat exchanger is not required. The Solaris-DB is a direct Drain-Back system, where the water in the store is supplied directly and without heat exchanger to the solar panels, heated and then stratified into the store. This increases the efficiency of the solar collectors and the entire utilisation of the installation.
In all ROTEX solar thermal stores, solar heating support has also been integrated ready for connection, alongside the solar hot water generation. If the solar heat is not consumed immediately, the ROTEX solar thermal store can store large volumes of solar heat and it is possible to use the heat for hot water or home heating hours later or even the next day.
