If so, I’m lost as to how!!!

Look at this post by @Zarch although I’m not sure how to add that to the app

Before we start, we have to remind ourselves of the following Heat Output = Specific heat capacity x flow rate (l/s) x (flow temperature - return temperature) Specific heat capacity (SHC) of water is 4.2 and it’s 3.8 for Gylcol. Flow Rate conversion m3/h to l/s = (m3h * 0.277) Flow Rate conversion: l/hr to l/s = (l/hr / 3600) So 860l/hr = 860 / 3600 = 0.238 l/s 3.8 x 0.238 x 5DT = 4.5kW No if we go back to our ‘gold’ tech document, whilst it doesn’t list the 3.5kW model, it lists a 3kW…
