Hydronic Heating FAQs

Hydronic Heating FAQs

No, not every home, but most can. It all depends on the characteristics of your individual home. If you're building a new home, or an extension, there should be no problem.

If you want to add hydronic heating to an existing home, there are extra factors to consider. Options include using radiator panels, and adding another level above your existing floor. We'll be happy to advise you on how hydronic heating can work in your home.
Hydronic heating uses gentle radiant heat, which gives you true thermal comfort by warming all of the objects the room. That's natural warmth, much better than hot air being blown into the room. Hot water is quietly circulated through pipes to efficiently distribute the heat as required, usually by radiator panels or inslab piping. Why water? Because it can carry much more more heat than air. Think of hydronic heating as a delivery system, and it opens up the option of using the fuel source of your choice. Gas. Electric. Biofuel. Heat Pump. Solar. Your hydronic heating system can work with all of these. We'll help you choose the best options to meet your needs.
Because you have a choice of heat sources, you can decide which fuel will be the most economical now, and in the future.

Each room or area can be individually controlled so only the required amount of heat (and energy) is used.

Because hydronic heating warms everything in the room, you can set the thermostat lower than with forced air systems. Each degree you lower the thermostat reduces your energy use, and cost, by about 10%.
There's no noise. Hydronic heating is quiet. There's no sound of a ducted system switching on and off. There's no sound of air rushing through the ducting. There's no fan noise. Just quiet.

There's no dryness. Ducted heating systems blow dry, hot air to warm us. Hot, dry air that can dry out our skin, our throats, our eyes. Hydronic heating gently warms everything in the room, so you'll enjoy true thermal comfort.

There's a constant, gentle heat. There's no on-off cycling. With a ducted system, things cool down, then the thermostat turns the system on, things warm up. Then things cool down, and the thermostat turns the system on... you know! Hydronic heating keeps you warm with a gentle, natural warmth.

There's natural comfort. You may have experienced this. You're sitting in your chair. Your body feels warm, but your feet are cold. Then, when you stand up, your head feels hot. Why? Because the hot air you're relying on for warmth, and paying for, is doing what hot air does. It rises as high as it can. Hydronic heating's gentle radiant warmth, and natural convection current warm everything in the room, including your feet!

There's no dust. Forced air systems push air around. It can carry dust. It can carry allergens that cause allergic reactions or aggravate asthma. It can help circulate pathogens that can spread sickness. Hydronic heating doesn't rely on blowing hot air, so avoids these issues.

There IS efficiency, and lower costs. You can use less energy to produce more warmth. Less heat is lost through ducting into the roof. Lower heat losses, and lower thermostat settings, mean lower energy bills.

Maintenance. A hydronic heating system has few moving parts, so service and maintenace costs you less.
Frankly, because every hydronic system is designed for different houses, with different distribution systems, with different heat sources, and of different sizes, anything we could put here would almost certainly not reflect your individual needs. Telling you some of the cost of the cheapest system doesn't help you. Read more here...
It depends which is best to meet your needs. Hydronic heating systems give you a choice.

Think of a hydronic heating system as a distribution system. It's a heat didtribution system that can have a number of different heat sources 'plugged in'. Your choice of heat source will be governed by fuel availability, initial cost, running cost, and other factors. You always have the option of augmenting or changing the heat source in the future.

The most common heat source in urban areas is a gas boiler. It's simple, and is the least expensive to instal initially. You may want to consider the current and likely future cost of gas in making your decision.

Heat pumps can be very efficient. They can be air-sourced, or ground sourced (geoexchange). They have a higher initial cost, but low running cost.

Solar collectors can be used as standalone heat sources. The running cost is low, but you need storage to provide hot water when the sun goes down. Solar can also be used in combination, boosting other heat sources.

If you're on a farm or rural location, off the grid perhaps, with no reticulated gas, or expensive LPG at your property, and you're happy to chop wood, then a wood burning fireplace or stove and/or a “wet back” fireplace or stove is ideal.

No timber on your property? A Bio Fuel pellet fireplace or a heat pump is the common choice. Although an LPG gas boiler is also an option if you are happy to pay for the LPG.

Don’t want a fireplace or gas boiler? Then a heat pump solution could be for you. Especially if you have a PV system, or are looking at getting one. The free electricity it will create from the sun will give a good contribution to the cost of the electricity required to run a heat pump.
