When we talk about heat pumps, we usually talk about running costs, sizing, efficiency and insulation. But there’s one thing that quietly wrecks systems up and down the country: poor water quality.
Most homeowners don’t even know it’s an issue until they’re facing breakdowns, failed parts, sky-high repair bills and warranties that disappear when you need them most.
This episode of Homeowners’ Q&A rips the lid off the hidden mess happening inside thousands of UK heat pump systems. We sat down with Ricky Prescott, Patrick Wheeler, Dirk van Lennep and Nigel Day who between them have been called out to fix the sludge, leaks and corrosion that shouldn’t happen if the system was properly flushed, treated and protected in the first place.
They discuss everything from flushing to whether you should trust chemical inhibitors or go the VDI 2035 route. If you think water is just water, you need to hear what happens when the wrong fill water starts attacking your system from day one.
It’s not about scaring homeowners. It’s about empowering them. Because water treatment and proper system care are some of the few things you can actively control once the heat pump is installed. Skip it, and the most expensive bit of kit on your property could fail long before it should.
Whether you’re a homeowner wondering why your radiators are full of sludge, an installer wanting to protect your reputation or just curious how to make your expensive heat pump last decades this is your behind-the-scenes crash course.
If your installer doesn’t mention flushing, inhibitors, fill quality or water tests, send them this episode.
