Direct HIU Replacement: A Flexible and Cost-Effective Approach for Upgrading Heat Networks
For installers, heating engineers or property and facilities managers, the costs, time and hassle involved in upgrading a heat network can be expensive and disruptive. As one of the UK’s leading providers of fully integrated heating, metering, pay-as-you-go and billing and bureau services, WilSon Energy believes direct HIU replacement services provide the ideal alternative.
It’s inevitable that with constant wear and tear, a heat interface unit (HIU) will eventually go beyond its repairable life – even with regular management and maintenance in place. Often when this is the case, it is easy to consider installing replacement HIU’s, which is costly and can involve significant disruptive work and extensive pipework modifications. An alternative, more efficient and cost-effective solution is to carry out a direct HIU replacement – swapping out an old HIU for a new one, with no additional installation or repair work.
As an approved UK partner, stockist and distributor for market leading HIUs, plus our own range of units and online spare parts store, we understand that there are over 70,000 KaMo/KVM Energi units installed on heat network systems across the UK. Many single plate heat exchanger units are installed, since the early 2000’s in older residential developments or commercial properties and we have over 15 years of experience supplying spare parts to keep heating systems running efficiently with minimal cost and effort.
Tried and trusted
Over time, our customers have realised we are not only a supplier of complete HIU’s and spare parts. Our network of trained engineers across the UK provide full service and maintenance for HIUs with unrivalled expertise – if our customers aren’t sure of the parts needed, we can advise remotely, providing a quote and stock availability.
We know that time is money, so we’ve also designed units that act as a complete replacement that can be installed with ease. As the connection configuration is the same, as well as the pipework centres, there’s no need for complicated pipework modifications. It is as simple as isolating the valves on the existing unit replacing it on the wall and bringing back into service, and the old cover can even be used without having to replace it.
Bespoke and flexible
Flexibility of these bespoke services are a key benefit, but it’s the savings delivered straight back that really make the difference. With so many property and maintenance managers focused on sustainability and environmentally-friendly utility solutions, as well as being under pressure to keep costs to a minimum, being able to replace a unit rather than the whole system has added appeal, and is just one example of why WilSon Energy is one of the UK’s leading providers of fully integrated Heating, Metering, Pre-Payment and Billing & Bureau Services for residential homes and commercial developments.
