I am looking at a Worcester Greenstar Heatslave Oil-fired combi for our house, there are 3 different models (12-18, 18-25, & 25-32) they all offer different hot water flow temperatures, and it would be the larger 25kW - 32kW model that I would like to have due to the improved HW flow rate.
The question is, in the product info says '25kW' as a minimum output, what happens if only 1 or 2 radiators are calling for heat (there are only 9 radiators in the house and this is much lower than 25kW loading) maybe only 8-10kW instead. Will the boiler automatically adjust down like a normal boiler would.
Or I may have got this completely wrong... help please!!
