Indeed. My point was that if you design for a flow temp of 50C at -3C based on a 10kW heat loss, and in reality the heat loss is more like 7kW then yo...
@petch just wondering how your averaged heat loss survey data compares to actual usage data. Is your existing boiler gas, and if so do you have access...
@petch Yes, if the flow and return pipes immediately split into 22mm runs for upstairs and downstairs, then each branch should theoretically be able t...
All great advice 👍 Going back to radiators and pipework sizing, once you have a heat loss calculation, broken down room by room, you can st...
Hi @fretless6 Mike, I have experience with Taggas (Retford), as they installed my system (a 12kW Samsung unit) on an ECO4 grant. The design proces...

@jamespa This does make me wonder though, how much more energy does the typical household use to heat a house constantly at 21C (heat pump) versus the...
Flow is what transfers heat, so when you say take heat from upstairs to downstairs, what you mean is to increase the flow downstairs by limiting the f...
Absolutely, this is typical usage for Octopus Cosy users, where the daytime cheap rate slot is 1-4pm. I know from my own experience and usage data, th...
