Who Fits LST Radiators?
17-01-2019

LST Radiators can be an invaluable safety asset to a school, hospital or care home because they reduce the risk of scolds and burns, making environments safer for staff and service users.

Because of the nature of low surface temperature heating solutions, it’s vital that they are properly installed by the right team. Contour have been blogging about who should fit your LST radiators and why proper installation is key.

Project Types

LST radiators should be installed by plumbing and heating engineers.

On a traditional build project, M&E consultant engineers will have already specified what the design and size of the LST radiator will be to be when it’s installed. This ensure that you always get the best heat output for the space.

This differs from design and build projects. In these projects, it’s up to the contractor to design the system and they choose the size of the LST Radiator.


The Installation Process

When installing an LST radiator, the first thing that needs to be considered is the final position it will have on the walls.

In areas with limited spaces, it’s important to know where the LST will be to help decide the placement of furniture and other services which could otherwise clash with the casing once it’s been installed.

Once the LST radiator has been hung on the wall, the flow and return water feeds can be connected.

The entry pipes to the LST radiator can depend on each location. However, the neatest solution is to have the pipes entering from behind it. This means you don’t have surface mounted pipework taking up valuable space in the room.

Once the heating system has been piped up, it can be filled with water and tested for leaks. Once this process is complete, the casing can be installed over the top.

Depending on the entry of the pipes and the flooring design, the casing may need to have cut outs in it to allow it to fit neatly over the top.

Once the radiator guard is installed to the manufacturer’s guidelines, it can be sealed up with a suitable mastic.

Depending on the environment and the client’s needs, the heating engineer can also install a range of thermostatic radiator valves (TRVs), these can include:

• Internal- inside the radiator cover. This is only recommended when the LST radiator is connected bottom bottom opposite end (BBOE).

• Remote sensing- inside the LST radiator cover. This is used when the radiator has been connected top bottom opposite end and the remote sensor can be installed at the bottom of the cover.

• External- outside of the radiator cover which enables the client to turn the radiator temperature up and down without needing to gain access to the radiator cover.

Some manufacturers include a survey service which means that any cut outs for surface mounted pipework, skirting and other services can be cut around in the manufacturing process.

This means the radiator guards can be installed at a later date when all of the first fix items of the project have been installed.

This will minimise damage as the radiator guards won’t be installed too early or in storage for a number of months on site.

Conclusion

LST radiators need to be installed by qualified plumbing and heating engineers.

The type of building project will affect who specifies and designs the heating system. On traditional build projects M&E consultant engineers will specify the design and size of the LST radiator whereas the contractor will design it on design and build projects.

Some LST radiator manufactures will offer a survey service to ensure that the cut outs, skirting and other furnisher are included during the manufacturing process so that the radiator covers can be installed after the first fix items have been completed.
