Can this boiler heat water?

ninjarambohd

Hi everyone. Just got a quick question. My landlord got a plumber to install this new boiler in. Unfortunately it doesn't heat the water and my landlord says that this model is only capable of heating the radiators and not water.

I went online and its instruction manual says it does have the capability to heat the water and radiators. It also has the functions on the boiler itself but it doesn't work.

The model is an Ariston Clas One. I have also attached pictures of it below.

Can this boiler heat water as well or is my landlord right?

All boilers can provide hot water if the house is plumbed for it; either combi boilers providing direct hot water or by heating a tank via a coil. You need to get a lot more information on how the house is (and was) plumbed.

It's a combi-boiler and has controls for the hot water on the left (note the tap symbol) and radiators on the right (note the radiators symbol).

If you press the + button on the left side, I'm guessing it should turn up the hot water - which would usually be at about 55-60ºC

Thank you both for your quick response. Yes, the house does have the capability as my previous boiler fro. 17 years ago heated the water no problems.

I do press the + button but it doesn't work at all.

The plumber probably turned off the coil in the cylinder and forgot to open it again.

Can you post a picture of the hotwater press/cylinder so we can show you which valves to try opening.
when the boiler is on you should be able to find a pipe that is warm to the touch ending in a valve that is cold above it.

Sure thing, I will post a picture now. Thank you.

I didn't know which parts I had to take a picture of, so I took pictures of all the parts around the boiler.

And this is of the hot water press.

Does the valve in the hot press turn anticlockwise at all?

loyatemu

so how is your landlord suggesting you heat the water? just using the immersion?

I have just come on here to post the exact same question so I'll ask here:

Just moved into a new place (gas heating), it has a thermostatic shower which I understand needs to be fed hot water. I don't want to just use the immersion because of the cost. There's a timer switch for the heating which works grand, and also one by the hot press that does nothing I can see when used by itself.

I turned both timers on (heating + hot press one) and there's a pipe going to the bottom of the tank that feels hot, but the tank itself isn't. Is this hot water from the boiler being fed to the hot press, but that valve is closed? I can turn it anti-clockwise.

This is probably basic stuff but no experience of it.

Exactly yes. He says just use the immersion. I did tell him that the immersion has no timer and that the electricity bill is going to go over the roof,but he said, I don't care, not my problem.

No unfortunately, it doesn't.

Well unless it's some weird clockwise-to-open valve there's a problem with your heating system. The two boxes on the right are likely valves for your zoned heating system. Can you operate upstairs and downstairs independently for instance? Is there a control panel somewhere apart from on the boiler? If both of those valves are closed the water should have nowhere to go except through the cylinder (apart from that pipe in the corner, not sure what that's for).

If you turn the heating on which of the pipes around the cylinder get warm?

The boiler heats your hot water cylinder. The problem is that your coil has air in it, or the red valve is closed. It has nothing to do with the boiler itself.

Is the horizontal pipe on the floor hot/warm to the touch when the boiler is on and you have hot rads upstairs?

Based on the cylinder pics it doesnt look like the system is plumbed for two zones (the same pipe that would heat the water looks branched off under the floor to me, probably to rads), did you have 2 zone control before the new boiler? (i.e. could choose between water or rads?)

If that pipe is hot then check the red valve as advised already, it should only turn a tiny amount clockwise if its is open (dont leake it fully open as it could stick)

If the pipe is cold then it seems like an issue at the boiler.

If that pipe is cold and the radiators are hot, then it’s a problem with the pipework, not the boiler.

I tried turning the valve and it doesn't work. I don't think it has anything to do with that at all as on the boiler when I press the buttons for the radiators it works and it brings the degrees up however for the water the function just does absolutely nothing.

The buttons on the boiler have nothing to do with hot water, unless it’s s combi. You don’t have a combi. Stop pressing those buttons. Use only + - on the right For temperature control.
The problem is on the coil, which has been pointed out by more than 1 plumber here already.

So it may be fully open?

Tell your landlord that you need the new BER certificate, as he has significantly changed the heating system.

By at the boiler i meant the motorised valve or potentially the electrics within the boiler itself.

OP do you have a separate programmer for heating and water anywhere else?

I'd guess your old boiler didn't have controls built in so you should have an old programmer... is that still in place or was it removed?

Why? What Would that solve?

Presumably BER will be worse if the only way to heat water is via immersion?

No, I meant, what on earth would a BER do in this situation. It makes no difference to the landlord or tenant

Landlord is obliged to issue one.
Might spur him to get a plumber in to fix the issue.

I don’t think an airlock in a coil will affect the BER.

Changing the heating system will.

Quit being so argumentative please.
Makes you look a bit silly.

I’m not! I know those boilers inside out. The problem is external to the boiler.
Suggesting a BER cert when the problem is probably an airlock is absolutely stupid

I wish to thank every single person on this forum. I got a plumber to come over and he managed to fix it somehow. The landlord wasn't responding or doing anything so I got down to business myself.

The boiler is now heating the water perfectly. Thank you.

Hope he gave you a BER cert afterwards.... :pac: jus kiddin'

Well done, as most of us figured, it had to have been something straightforward, a stuck or closed valve, an airlock or a minor issue on the electrical side.
