The heat created is then transferred to the water which runs through your floors. With hydronic heating, the heat can be created by a large number of processes (gas boiler, heat pump, bio-fuels, solar, etc).

Even if you have free PV solar power input, you are still limited to the low efficiency of the heat generation (1.0kW of free solar power = 0.99kW of free heat). The efficiency of this method is around 99% (meaning for every 1.0kW of electrical input, you get 0.99kW of heat output). Because the cables provide resistance to the electricity flow, they heat up (just like your kettle does). There is only one way to warm up the electric cables in the floors, and that is by running electricity through them. Is hydronic floor heating cheaper to run than electric floor heating? We have also seen some poorly designed and installed systems which cost upwards of $3.60 per hour of operation per 100m2. What the input price of the energy is (gas, electricity, waste heat, etc.).įrom our experience if the entire system is designed and installed to perfection, the system can cost between $0.162 and $0.378 per hour of operation per 100m2. The heat source type (gas boiler, air-source heat pump, geothermal heat pump, etc.).Ĥ. The design and installation of the hydronic heating system (how well it produces the heat, how well it moves the heat to where it’s needed, and how well it emits the heat into the rooms).ģ. The thermal efficiency of the building (how much heat it loses and how quickly).Ģ. What is the running cost per hour for hydronic floor heating?ġ. This is a good option for people wanting to minimise the amount of equipment installed at their houses. Yes, however, this must be planned for from the start, and usually additional equipment is required. Can the same system supply my tap hot water? A well designed and installed heating system covers 100% of your heating requirements effectively and efficiently. Some people think that floor heating is only there to take the edge off cold concrete floors, and other heaters are required to keep the house comfortable. Do I still need other forms of heating in the house? (And no, Perth’s “dry sand” is not an insulator – it still conducts heat at a level many times greater than polystyrene insulation (for example). Therefore, preventing the heat from travelling to where you don’t want it to go – and directing it into the rooms where you do want to heat – will ensure your system heats as you would like it to, within the running cost that you expect.

You don’t have to install thermal insulation (other than what’s required according to the building code), but this means that vast amounts of heat will escape to the surrounding environment where it’s colder (such as the outside air, the ground below, other solid structures nearby)… this is where the heat wants to naturally travel to the most – where it’s coldest. Floor cooling output can be between 20-50W/m2, whereas the cooling load for typical houses can be around 150W/m2, and for more energy efficient house around 70W/m2.

This is partially due to the way we build our houses in Australia (lots of glass windows and doors, varying levels of air-tightness and insulation), but also because there is ‘latent’ load which needs to be removed from the air (heat held in air moisture), and mainly due to the fact that physics works against floor cooling, because cool air remains close to the ground and warmer air remains above this uncooled. Generally in our Australian climates, floor cooling is does not cover the required cooling load of the building. Can I use floor cooling instead of aircon? The pipe can be repaired, and good brands of pipe guarantee their repair even when covered again with concrete. Sometimes penetrations do occur by accident on site, however, it is immediately recognised as water squirts out of the penetration (the pipes are pressure tested after installation, and remain pressurised during construction).

They will not burst or leak by themselves (they have a lifespan of up to 100 years, and are extremely durable). Can the pipes leak… and what happens if they do?įloor heating pipes can only leak if they are cut or punctured – which means someone has to physically drill, cut or penetrate them.
