Economy7 water heats overnight to warmish but not Hot?

Anonymous user 28/02/2024 - 3.56 PM

Hello, I've an Economy7 tank water heats overnight to warmish but not Hot i.e. the Bottom Element? I've had an electrician check and he says the electrics are fine and this makes sense as it does heat and the Wall Rads also work? I then ask a plumber he says the Plumbing looks fine. This is costing a fortune to go back and forward between Plumbers and Eletricians. I've also had the Consumer Units changed and check recently (after I had the problem) he also checked the Electrics and says he thinks alls ok? Help! Update: There isn't any timer its just straight to E7 Re:Dials - I checked the bottom Theromstat (the top manual Element gets hot) and it was at 60 I think high anyway, I didn't know the element had a setting I thought that's what the theromstat inside did? Thing is the previous tenants who moved out said it was working ok. Only when I was checking and leaving it on did I notice it not getting hot?

Are you a tradesperson and able to answer this question?

As ELX has said. I attended one this week and timer was set for thirty minutes on E7 so wasn’t ever going to get hot

Hello. Element likely needs changing. Old 3kw copper elements do not last forever. These can burn out yet still show signs of working... even making a sizzling noise. A simple electrical test can confirm this. A plumber can do this providing the tank is in good condition for the removal of the element. Good luck, Bob.

It could be few things. It may be continuing to allow cold water in when full and overflowing. It may be a faulty thermostat. It could be a too low power element. It could be a leak. You need a heating engineer; a plumber, a gas fitter and electrician rolled into one. You could try isolating the tank when it is full and leaving it overnight to rule out some of these. ——— Forgot to ask, did either of them check the temperature dials on the thermostat/elements? ——— Did they take the caps off the elements and thermostats to check the dials. It is not unheard of for tradesmen to intentionally set the dial too low. Then sheer the screw head. Meaning as far as the customer is concerned it is faulty, and due to the broken screw they can never take the cap off to check the dial. Check the dials.... ——— The elements and thermostat are normally on the same part. Two elements and one thermostat for each the top and bottom. The bottom should be around 40 - 50 as that is just doing the start. The top should be at 60. As you’re a landlord the tradesmen are probably squeezing you for cash rather than doing proper investigations. It’s very common, rental properties are a cash cow for many industries. ——— When you say manual one, do you have the bottom element on E7 and the top with just a manual on/off? If so, you might be best buying a timer unit with a boost/override function for the top.

Hello. If you've had an electrician out I'm sure he set the controls correctly and checked the operation of both the element and thermostat. This could be due to limescale encasing the element. It's a calcium deposit which encases elements in hard water areas and prevents the heater transmitting heat to the water efficiently. Best wishes
