If you’re working with heating systems, making sure you have Heat Interface Units (HIUs) regularly maintained is among your primary concerns. Maintenance ensures efficient operation, lowers energy usage and avoids costly repairs.
Maintenance of the Heat Interface Unit – Why you need it will discuss the reasons residential HIU servicing in London is vital.
What is a Heat Interface Unit?
HIUs play an essential function within modern systems of heating. They connect individual residences and homes to a centralised network that offers hot and warm water via a central source of energy instead of each individual boiler made of gas.
When switching into heat interface units heating networks will operate more efficiently and more efficiently.
Heat interface units can significantly reduce energy demand when they’re powered by renewable sources like biomass, solar thermal, or heat pumps. HIUs can decrease energy consumption, save money on heating bills and reduce your carbon footprint.
1. Improved Performance
In time, High Efficiency Unit (HIU) stores will naturally build up limescale, sludge and debris (particularly so if you are situated in a hard water area or on an older heating network). This builds up in parts of your HIU that shouldn’t have blockages. The most common places for this to occur are inside the heat exchanger itself. These blockages mean your unit has to work harder to provide heating and hot water to your tenants.
When you get your HIU serviced on a regular basis, we flush these blockages out and restore your heat transfer to its optimal level. This means your unit can perform at its highest capability. Which in return provides your tenants with better and more reliable heating/hot water. All whilst your system isn’t having to work overtime.
2. Cost-Effectiveness
Did you know that being inefficient with your energy can affect your bottom line?
If you’re a social housing provider or local council, we know your budgets are tight. That’s why when your HIU becomes sluggish from not being serviced, it’ll use more energy to heat and provide hot water to your tenants. Meaning you’re losing money on your utilities.
Maintaining your HIU keeps it running smoothly and efficiently. Cutting down on wasted energy and keeping small problems at bay. Which can all add up to big savings when you’re on a limited maintenance budget.
3. Increased HIU lifespan
All machines break down over time, and HIUs are no different. When maintenance is ignored there is increased wear and tear on moving parts. Which leads to pumps, valves and heat exchangers giving up the ghost far quicker than they should.
Not only is this expensive to rectify by replacing parts, (or even whole units), but it’s also disruptive for tenants.
If each part of the HIU is regularly serviced ensuring it’s working efficiently you’ll reduce unnecessary pressure on individual components. Lengthening the overall lifespan of your units and saving you from hefty replacement costs.
4. Lower your carbon footprint
If you’re reading this, chances are you’re being asked to hit net zero carbon emissions from your housing stock sooner rather than later.
An inefficient HIU will take longer to heat homes. Increasing energy bills and pushing your tenants towards using more fossil fuel burning appliances.
