R290 refrigerant, which is commercially known as refrigerant grade Propane, is being increasingly used in air source heat pumps because it is a more eco-friendly refrigerant option. If you are a heat pump installer interested in working with R290 heat pumps, there are some important differences you need to be familiar with. In this blog, we will explain about the importance of understanding R290 refrigerant including safety considerations and best practices for installation.
The number of air source heat pump installations taking place each year is increasing and more qualified heat pump installers will be needed if future heat pump installation targets are to be achieved. It is important than any engineer looking to work with heat pumps is suitably trained to ensure that the systems they install are correctly fitted and commissioned to provide their customers with years of reliable, low carbon heating. This blog talks through some of the key stages of the installation process.
The changes to Part L Building Regulations, which came into effect on 15th June 2022, stipulate that a full room by room heat loss calculation must be carried out prior to installing a boiler. Grant UK has developed an Oil Heat Loss Calculator to help with this requirement so to support installers with understanding how to use this calculator, we have shared this blog which includes a step-by-step guide about how to carry out a heat loss calculation for an oil boiler installation.
