New menu and link to source code
I’ve updated the collection of heat pump calculation tools that I’ve been building slowly over the last few years to have a menu system and link to the GitHub source code. This should improve navigation and provide a more connected experience.
Note: While some of these tools have been developed with testing on mobile, most are best viewed on a wider screen and need more work for a nice mobile experience.
New tool: Weather Compensation calculator
List of available tools:
-
Super Simple Heat Loss
Explore the difference between custom measured assumptions and those typically used from the CIBSE domestic heating design guide. -
Weather Compensation
Calculate optimum weather compensation settings for a heat pump -
Heat Pump System Performance Calculator
Calculate heat pump SCOP based on design flow temperature -
Dynamic heat pump simulator
Explore continuous vs intermittent heating, temperature set-backs and schedules -
Explore Solar Matching
Explore how much home electric + heat pump demand can be met by solar and a battery -
Plate heat exchanger, fixed flow temperature
Calculate heat output and COP for a system with a counterflow plate heat exchanger between the heat pump and the radiator system. Fixed flow temperature version. -
Plate heat exchanger, fixed heat transfer
Calculate heat output and COP for a system with a counterflow plate heat exchanger between the heat pump and the radiator system. Improved fixed heat output version. -
Low loss header
Calculate heat output and COP for a system with a low loss header between the heat pump and the radiator system -
Volume Simulator
Explore system volume, starts per hour and cycling -
Volume simulator with heat pump COP
Explore heat pump minimum modulation and cycling’s effect of COP -
Pipe pressure loss calculator
Calculates pressure loss using the Darcy Weisbach equation with the friction factor derived using the Newton-Raphson method to solve the Colebrook-White equation. -
Building indoor CO2 simulator
Explore effect of building occupancy & air change rate on indoor CO2 concentrations. -
Storage simulator
