Underfloor heating allows gentle radiant warmth that doesn’t dry out the air. Warmth feels natural and doesn’t involve any breeze or hot surfaces. Hydronic supplies allows water to heat the floor, water being an efficient means of carrying heat.
We know from basic science that hot air rises. Circulating warm air through a house is compromised by this, especially if there are high ceilings. The warmth is largely lost as it rises; the floor is hardly heated at all. Underfloor heating keeps the floor warm, usually the coldest area, and does not waste heat on the air above out heads. Correctly designed, the hydronic heating feels like natural pleasant warmth.
As with any system the correct design is as important as the components. The hydronic supplies should be arranged so that water flow is consistent; if there are inconsistencies in flow the heating system will work inconsistently, regulation will be difficult and temperatures of rooms will change as other rooms are turned on or off. It is not too difficult to use parallel and series pipe design to allow all rooms to be consistently serviced with heated water. This is best done when the house/building is first constructed, with the hydronic pipes set in the concrete.
Hydronic systems are safe for the elderly, children and pets; there are no hot surfaces to be burnt upon. There is virtually no maintenance and rooms can be effectively heated within 30 minutes.
