Precision for Performance
At Heat Engineer, we've built a Pipe and Pump Sizing Tool that takes the hassle out of designing heating systems. Whether you're working on a heat pump installation or a traditional boiler system, this tool helps you size pipes and select the right circulating pump quickly, accurately, and without needing a background in complex calculations.
No more guesswork or flipping through charts and tables. Our Pipe and Pump Sizing Tool is designed with the everyday heating installer in mind. It works alongside your heat loss calculations and instantly tells you what pipe size you need, how much flow is required in each room, and which pump will do the job best incorporating the Grundfos pump sizing tool.
Everything is automated and easy to follow — just plug in the basics, like your flow and return temperatures, and the system does the rest.
When it comes to pipe sizing for central heating,we know how important it is to get it right. Oversized pipes cost more and undersized pipes lead to poor performance. Our tool automatically recommends the correct pipe diameter based on your chosen pipe material, flow rates, and target temperature drop.
A simple colour-coded system (green, amber, red) tells you instantly if your choice will work — no need for second guessing. You'll also see the friction loss per metre, so you can be confident the system will run smoothly.
Our tool doesn't just stop at the pipes. It also helps to size your circulating pump with identifying the index circuit from adding up the pressure drop and calculates the total pump head you need.
Using the Grundfos selection pump tool will then confirm the ideal pump required.
With our Pipe and Pump Sizing Tool, there's no need to be an engineer. It's built to guide you through each step, with tooltips and helpful hints throughout. All you need is your project's room sizes and heat loss details.
When you're done, you can generate a detailed PDF report showing your pipe diameters, flow rates and recommended pump size — ideal for your job file, customer handover, or installation team.
Whether you're working on a low-temperature heat pump or gas boiler system, our tool makes it easy to get your pipework and pump sizing right. It's a must-have for any modern heating system design.
