MCS Design

Choosing an experienced ASHP supplier is essential when it comes to Heat Pump Design you need to be confident that the system will be efficient and work as expected, keeping running costs low. 3F Heating offers the following as standard:

  • Advice and guidance on the suitability of an ASHP for the project
  • Full heat loss calculations for the property in order to correctly size the ASHP
  • An accurate quotation for the system components in line with MCS and RECC standards
  • Support with MCS compliance, including on-site commissioning
  • Mechanical and electrical drawings specific to the installation as well as clear installation manuals and customer user guides


The heat pump controls and pipework layout are very similar to a traditional gas or oil boiler, configured as a Y or S plan industry standard layout.

  • The ASHP is placed on a flat concrete base external to the property with the appropriately sized flow and return heating pipes and electrical power cable running from the unit into the property
  • Electrical work should be carried out by a qualified electrician in the conventional way as you would for a gas or oil boiler

Commissioning and maintenance

Once the installation of the mechanical and electrical heat pump components is completed, the ASHP unit will be ready for commissioning. We handle all the MCS paperwork putting the clients at ease. We aim to provide the best service and as smooth handover as possible,

What is the BUS Scheme?

The government will provide grants to encourage property owners to install low carbon heating systems such as heat pumps, through the Boiler Upgrade Scheme (BUS). These grants will help property owners overcome the upfront cost of low carbon heating technologies.
