Combi boiler modulation for low heat output .

Jul 18, 2019· Discuss Combi boiler modulation for low heat output in the Central Heating Forum area at L. LoneWolf. Jul 17, 2019 #1 I'm looking to buy a 24kW combi boiler with only 4 radiators rated at 1.7kW each, so I can later expand and add more radiators. I expect relatively low heat dissipation from the heating circuit. ...

oversizing modulating boiler — Heating Help: The Wa

The modulation capability of these boilers is what gives them the extra energy savings, not just the return water temp. The higher the boiler load, the lower the efficiency. The same for the supply and return temps..... the higher they are the lower the efficiency. This is $$$ we are talking here.

Modulating condensing boilers (mod-con boilers) can increase combustion efficiency to about 96%, up from the 80% efficiency of non-condensing boilers. They provide a range of firing rates to match the variable heating load of the building. However, mod-con boiler efficiency depends on the temperature of the water returning to the boiler.
