Do you have central heating but no hot water?

My boiler is an ideal logic heat 15. I have hive active heating. When I turn the central heating on in the Hive app, the hive receiver calls for central heating and the boiler fires up. It is working correctly. When I turn the hot water on in the Hive app, the hive receiver calls for hot water but the boiler does not respond.

When does the HW come on for central heating?

The HW was timed to come on from 06:00 – 06:30. It did. The call for HW was made, the boiler responded correctly and hot water was produced. Perfect. We consumed all the hot water and made sure it was all used by opening the HW tap and confirmed it as running cold.

Why is my hot water heater not working?

In some cases – such as with broken diverter valves – the hot water will only work when the central heating is fired up, whereas in other cases, the hot water will not work at all. In these situations, the problem will either be with your boiler settings – something you can resolve yourself – or within the internal components of the appliance.

What happens if there is no hot water in the boiler?

The boiler will still be working perfectly; however, the flow of water between the heat exchange will be reduced. You simply have to run the hot tap at a slower rate than you normally would.

What to do if your central heating is not working?

If you cannot get your hot water back on by changing your controls, timer and thermostat or by resetting the appliance, then you will have to contact a Gas Safe engineer to get it examined. Why is my central heating working but not the hot water?

What to do if your boiler is working but you have no hot water?

If your heating is working but you have heating but no hot water or vice versa, it is likely to have become stuck. You will need to contact a Gas Safe engineer to solve a problem with your diverter valve .

What happens if your central heating is leaking?

Check for leaks. If your central heating is leaking, this will lead to a drop in pressure, along with a loss of water. Besides the problems with your hot water, this may also lead to rot and structural problems if left untreated, so it is worth checking to be sure.

How can I get my hot water to work?

If there is such a valve with a wheel on top, open the valve (anti clockwise) half way (say 1.5 turns for now). Turn on the boiler and check that hot water reaches the cylinder from the boiler on one of the two pipes. (2). If not, is you hot water controlled by a time clock and thermostat or “zone controller” ?

Why do I only need hot water in the morning?

Especially given I only need hot water in the morning for showers. Is this simply a mis-understanding with how this particular type of system has to work in order to deliver heating, or is there an issue with the wiring between the programmer and the boiler?

Why do I have no hot water in my house?

When you turn your hot tap on, the diverter valve temporarily shuts off the water supply for your central heating, and when you turn the tap off, the valve reopens and feeds your radiators. Over time, diverter valves can become degraded and faulty or can be stuck in the wrong position, cutting off your hot water supply.

What are the common problems with water heaters?

13 Common Water Heater Problems (Tricks to Fix) 1 1. No hot water. If you have no hot water, there are several possible reasons, and you need to work through each of them methodically to eliminate 2 2. Not enough hot water or water not hot enough. 3 3. Water too hot. 4 4. Water takes too long to heat. 5 5. Low water pressure.

Why does my central heating work but no hot water?

A relatively common fault with boilers sees the central heating work with no hot water. In some cases – such as with broken diverter valves – the hot water will only work when the central heating is fired up, whereas in other cases, the hot water will not work at all.

Why is my central heating not working at night?

Keeping the heating on during nights with extremely low temperatures. If your boiler is working but there is no hot water or vice versa, then the issue most likely comes from a faulty diverter valve. It works like a traffic policeman, directing the flow of hot water to either the heating or the taps.

Why does my hot water heater not turn on?

The pressure is within normal range, all radiators have been bled and the boiler will sometimes run for about 2 minutes and then switch off.No heat comes through to the rads. The lockout indicator light does not come on. This has happened suddenly, it was working fine up until yesterday. Any advice much appreciated.

Why is my central heating system not working?

If your boiler seems to be working and your hot water supply is still functioning, but your central heating is not working, then the problem is either down to the settings on your boiler and central heating system or because a component of the boiler – almost certainly the motorised diverter valve – is broken.

Why does my hot water heater stop working?

These valves switch heat between your water supply and your central heating. After prolonged use, a range of faults can develop in these valves, which prevent them from changing position; therefore, either your central heating or your hot water will stop working.

What does it mean when your boiler is working but no hot water?

If your boiler is working but there is no hot water or vice versa, then the issue most likely comes from a faulty diverter valve. It works like a traffic policeman, directing the flow of hot water to either the heating or the taps.

What should I do if my central heating is leaking?

You may prefer to get an engineer to do this for you. If your central heating is leaking, this will lead to a drop in pressure, along with a loss of water. Besides the problems with your hot water, this may also lead to rot and structural problems if left untreated, so it is worth checking to be sure.

Why is my boiler not producing hot water?

Diverter Valves If your home’s central heating is still working and it is just the fact there is no hot water being produced, then this is usually indicative of problems with a diverter valve. This valve’s job is to allow combi boilers to go from heating radiators to heat your hot water once you’ve turned a tap on.

Is the central heating only working intermittently but hot?

Over the last few days the central heating has only been working intermitently and I’d like to see if the issue can be identified (and repaired ecconomically if possible). The hot water appears to be unaffected by this problem as the boiler responds immediately when the hot water is switched on via the timer box.

Can a faulty central heating and hot water valve be repaired?

Also a chance like the previous that you may have a faulty motorised valve. They only way to be sure is yo check the movement of the valve (s) when turning heating and hot water on/off or remove programmer (making sure electrics switched off first) to see if the programmer in question has been set to fully pumped.

Is the hot water in the boiler working?

The hot water appears to be unaffected by this problem as the boiler responds immediately when the hot water is switched on via the timer box.

When does the central heating system stop working?

Central heating only works when hot water system is on My central heating only operates when the hot water syatem is operating. As soon as the water in the hot water cylinder has reached the required temperature and the boiler switches off the central heating stops (because the pump stops running).

Can a central heating system be used with hot water?

The timer/programmer allows for separate use of heating/hot water. It sounds like you need an engineer visit to confirm what system you have but sounds like it could possibly be an issue with the zone valve.
