We have a team of in-house Mechanical Designers who will take your project specifications and drawings to create the right design for your renewable heating, cooling and ventilation system.

We also offer a service to create the heat loss calculations for the project to ensure you are within MCS guidelines, you size your products correctly and you get the right outputs as per the specifications.

Our Design Service Includes:

  • Estimation of project
  • Pipe drawings for the radiant installation 
  • Detailed Bill of materials for the project 
  • Heat loss calculations

What are heat loss calculations and why is it so important?

Heat loss calculations play a critical role in the design, operation and maintenance of energy efficient buildings and systems to help optimise comfort, reduce energy consumption and lower operating costs.

The calculation determines the amount of heat energy that escapes from a building or system to its surrounding. This will determine the sizing and power needs of your system and also ensures that the right products are fitted for the building type. You cannot ignore the importance of insulation, window glazing and fabric of the walls when selecting the right heat source for a home.

The heat pump and emitters need to ensure that enough KW output is in place to be comfortable based on the heat loss of the building. A correctly sized heat pump and radiant system will ensure cost less to run, keep customers warm and will give great value for money.
