HIU-boilermaster

From time to time a standard HIU just doesn’t do what you want it to do, you may require a higher output, different pipework configuration or specific components and controls.

Sometimes advanced control technology isn’t necessary, and basic mechanical control is all that is required.  You may need more than one heating output zone, or you may wish to combine low and high grade heat on the primary circuit of the HIU.  We’ve produced products that can do all of the above and more.

We can design and modify a unit to fulfil your needs, we use high quality proven components, so the finished product is as reliable as the standard range of HIU’s.
