No Hot Water? Poor Flow? Common Combi Boiler Problems & Fixes!Why Your Strom Electic Combi Boiler

Hey there, fellow plumbers and DIY enthusiasts

Ever walked into a home only to hear the dreaded words—No hot water? Ugh, the panic! And if a homeowner starts complaining about poor flow from their Strom electric combi boiler, that's a whole new can of worms. Let's dive into some common combi boiler problems and how to fix them

First up, no hot water. This is often a result of a faulty thermostat or an issue with the diverter valve. Have you checked the settings and made sure everything is inline? Sometimes, it's just a simple reset that does the trick. If the thermostat isn’t clicking like it should, it might be time for a replacement. Trust me, your clients will appreciate the warm showers again

Now, let’s talk about poor flow. When you turn on that tap and it dribbles like it’s on a diet, you know there’s a problem. This could be due to a blocked filter or an issue with the pressure. Inspect the whole system and clear out any sludge or buildup. Sometimes just cleaning the aerator can do wonders

You might also encounter strange noises from the boiler. A banging sound? That’s not cozy, that’s a sign of kettling. It’s usually caused by limescale build-up or low water levels. A good flush might help, but if you’re in an area with hard water, consider suggesting a water softener to your clients

And let’s not forget about the pressure gauge. If it’s lower than a slumped-over teenager, we’ve got a problem. Check the pressure and top it up if necessary. Low pressure can lead to all sorts of headaches in the heating department

So, to all my tradespeople out there, next time someone hits you with the no hot water or poor flow line, you know exactly what to look for. And remember, a well-maintained combi boiler makes for happy customers and less stress for you
