Condensing boiler or low temperature boiler

Condensing boilers are designed in such a way that the flue gases can largely condense in the heat exchanger, so that that heat is recovered. These gases are lost in a conventional boiler. A low temperature boiler keeps the water on average at 35 to 40 ° C - in contrast to 70 to 85 ° C with a traditional boiler. Condensation is possible under certain circumstances.

VOORDELEN

A condensing boiler saves around 10% more energy than a low-temperature boiler.

LET OP VOOR

Over-dimensioning (= a boiler with too high a power) leads to more energy consumption.

Ensure proper dimensioning: let your (de) central heating operate at full power in very cold weather and at lower power during the remainder of the heating season.

Have a heat loss calculation made before you purchase heaters. Certainly do not choose a device with too large a capacity.

For domestic hot water, a boiler is often the best solution because it keeps a certain amount of water at the right temperature.

A boiler with a lower capacity cannot heat domestic hot water in continuous flow, unless you opt for a separate flow appliance.

Do you want the power to adjust continuously to the demand? Opt for a modulating condensing boiler in combination with a modulating thermostat and / or a weather-dependent control. The boiler must be able to modulate sufficiently low so that it can condense even when there is little demand for hot water.

Provide solutions for pipes that have to pass through insulation and air sealing.

Do you opt for phased renovation? You will have to heat less after certain renovation measures. Take this into account today if you choose a heating solution.

Adjust your ventilation after you have replaced the old boiler and thus prevent moisture problems.
