A Hydronic heating system consists of five components:
- The boiler heats water to a thermostatically controlled temperature. Boilers use natural gas, LPG, Off Peak Electricity or can be wood fired.
- The piping, usually made of copper or plastic (Rehau), carries the heated water from the boiler to radiators/convectors, and back again for reheating.
- A pump circulates the water through the piping.
- Radiators or convectors transfer the heat to the room. Several types are available.
- Thermostats control the heat levels to optimize comfort.
Hydronic Heating is safe for elderly people, children and pets. There is no danger of burn or scald as the system is fully enclosed with radiator temperatures well below boiling point. The surface temperature of natural convectors is pleasantly warm to touch.
Yes, most houses can have hydronic heating at any time, however, houses on a concrete slab become more difficult due to access for pipe work.
To install floor hydronic heating the approximate cost is currently around $500.00 per house square (9m²) of an average sized house, this of course depends on job difficulty and the individual specifications of each home.
As with all heating, insulation improves the effectiveness by reducing heat loss through walls and ceilings. The boiler is not running as often for a given output thus saving fuel bills.
Radiant heat is a form of hydronic (hot water) heat that circulates warm water through special tubing. Radiant heating systems heat objects throughout the room, so you can feel the difference. It simply eliminates cold draughts and keeps the heat at the floor, warming you and the furniture, not the air.
A high efficiency boiler is used to heat water that is circulated throughout the system. Each area can be individually controlled so you only use the amount of heat you need.
If you live in an urban area, the cheapest fuel will be natural gas. If natural gas is not available, LPG, Electricity or solid fuel boilers can be used, as well as solar.
A thermostat should be installed in a main living area (usually the family room). This should be located on an internal wall in an area free of draughts, and away from sources of direct heat, such as system panels or direct sunlight.
Hydronic Radiant Heating
There are major differences that you should be aware of between ducted and hydronic heating systems. Ducted heating circulates and re-circulates warm air via ducts around your home bringing with it airborne particles, dust and other undesirable pollutants, all of which trigger factors for asthma and other breathing allergies.
