Is it efficient?
Hydronic central heating started being used extensively in Europe when gas and electricity prices forced home owners to look for the most effective and efficient heating alternatives.
Today hydronic central heating is the most efficient and economical solution for heating homes in cooler climates. The energy used to achieve the same level of heat is much lower in hydronic central heating than when compared to any other existing heating solution on the market.
Energy savings are achieved through water circulation used for heating panel radiators, towel rails or underfloor pipes, as it is still warm when returned to the boiler (gas or electric heat pump). Because of this, less energy is required to reheat water again.

Research results show:
- The running cost of a gas hydronic heater is about 20 to 30 percent lower than a conventional ducted gas heating system,
- Buildings with hydronic heating have frequently shown lower energy usage then spaces with fitted forced air heating systems,
- Comparative studies have proven air leakage to be 26% lower and reduced energy use in households fitted with hydronic central heating rather than heating systems using forced air,
- Hydronic central heating provides a more even heat circulation in each room, therefore maintaining stable air temerature in each room is easier when compared to using an forced air heating system. especially with high ceilings,
- Using hydronic heating avoids a high degree of temperature build up near the ceiling, unlike ducted systems, which increases heat loss through the ceiling,
- The newest gas boilers efficiency can vary from 97% up to 105% depending on the heating water temperature selected (between 80 and 50 degrees C) and the level of house energy efficiency rating which results in quality of house insulation chosen.
