In-house assembly of our patented designed HIU sub-frames allows us to offer the client a fast and customised solution for any HIU configuration. When delivered to the construction site, the cabinet is ready for installation according to customer specifications and connection orientation.

Available in two different versions, in-wall and on­wall mounting, for most common system installations, the unit can be supplied for radiator connections and for underfloor heating (UFH). This can be in any combination of; six top, six bottom, three top and three bottom or four top and two bottom etc.

The sub-frame assembly is also available with optional first fix-rail and flushing by-pass valve.

The HIU can then be easily and quickly mounted on to the sub-frame, saving time and installation costs.

Wilson Energy has secured a contract for Lily House in Wembley, for the supply and commissioning of heat interface units and smart metering systems.

The project has utilised Wilson’s brand new design of the Type 4.1, heat interface units which are both WRAS approved and tested in accordance with the BESA test regime. Chosen for its low return temperature, compact design and easy installation with configurable connections, the unit has a two part lockable front cover and viewing window for the heat energy meter. A first fix installation was carried out by the contractor using a manifold rail and flushing by-pass unit.

The smart metering package provided to the client, includes heat energy meters, cold water meters and electricity meters, which measure the consumption used within each dwelling  and is shown on the consumers ENE3 in-home display unit. The heating and hot water supply will operate on a Pay-As-You-Go basis, which is linked into WilSons’ new multi-lingual billing platform, customer portal and mobile APP.

We are receiving a lot of interest in our Hybrid HIU, particularly for heat pump applications from specifiers and consultants. Our range of heat interface units are evolving to meet this challenge.

In the UK, networks will typically be designed around an output temperature of 45-50 degrees C, which will maximise the COP, minimising both CO2 and
electricity bills. The Hybrid unit works at these low temperatures (or lower, down to 35 degrees C).

Domestic Hot Water presents a particular problem. Although 45 degrees is hot enough for most uses (and building regulations limit tap water temperature to 48 degrees), stored hot water must be at a temperature of at least 60 degrees to kill off legionella. This is commonly achieved by an immersion heater in a domestic hot water tank, which takes up space and pushes up heating bills.

The Hybrid HIU negates storing domestic hot water in a cylinder which is clearly desirable both in energy efficiency terms and saving space, and instantaneous water heating offers one option to top up water heating if required.

With more than 1,000 units deployed and operational in the field, we clearly see many more opportunities in these low temperature networks.

WilSon engineers have installed our smart metering system at a commercial laundry site, providing site-wide automatic monitoring and targeting. Data capture of the main incoming supplies for gas, water and electricity and a sub-metering network, monitoring all energy and utilities across the site, with around fifty metering points, capturing all elements of the industrial process within the factory.

There are several makes of electricity meter installed in the switch room and at various local distribution boards around the factory and offices, which are providing a direct register read via an RS485 communication, linked to each of the data hubs installed.

The parallel communication system of the hubs provide both wireless radio and simultaneous power line data transmission, which gives a reliable and robust solution, across a site that is wide-spread, without the need for additional infrastructure. The client can view real time information on WilSon’s cloud based MDM (Meter data Management) dash board.
