Central Heating Pipe Sizing Guide

Choosing the correct central heating pipe for your home is important to ensure that there is an adequate amount of water flowing through the pipes that feeds the radiator to produce enough heat for the house. Below are guidelines that will help you determine the size of the pipe needed in your home.

Calculating the Required Flow of Each Radiator

To find the right pipe size for your home, first you need to calculate the required flow of each radiator. You could do the math by yourself if you have good knowledge regarding pipe sizing but if not, it’s advisable to have a professional do this for you because these people have special training and experience that makes their judgment and calculation more consistent and accurate.

Calculating the Resistance of Fittings and Piping between the Radiator and Each Junction

After calculating the required flow of each radiator, you should also have your flow resistance calculated. Again asking a skilled professional to do this would make things easier and concise. But ensure that the installer knows what he is doing and is not just someone who chooses a pipe size with no considerations; it is always good to ask for a second opinion.

Identifying the Circuit that has the Most Total Resistance

The next step is to have your circuit that carries the most total resistance be identified to make sure that every part of its components including the isolating valves, boiler and other vital parts are properly functioning and can endure the required pressure. Your installer can effortlessly identify this considering the calculations he has made, so this wouldn’t be much of a problem.

Finding the Right Pump Based on the Calculated Water and Resistance Flow

Finding the right pump is a lot easier now that you have the amount of water and resistance flow needed for your central heating system. A pump pressure will handle the total flow of the system; that is why it is important that you have accurately calculated the water and resistant flows to ensure efficient performance of the overall system.

Adjusting the Pressure to Find the Best Flow Rate for the System

Now that we have already calculated the flow rates and identified the right pipe, a pressure comparison can be performed to find the right combination of flow rates and pump pressure that will best work for your central heating system.

It is advised to hire a professional to do the calculations for all the procedures because their experience and knowledge gives them the ability to estimate the probable flow rate and pump pressure needed that best suits your central heating system.

After reading the guidelines in central heat pipe sizing, this will give you a good idea of your installer’s responsibilities in installing your central heat pipe size with the ability to ensure that all the factors needed to be considered are taken note of.
