Condensing Boilers Are Rubbish!

boozercruiser

I have had my Oil Fired Worcester Bosch Condensing boiler now for around 3 years and without spending all evening here going through it all, generally speaking it has been a nightmare purchase.

Thank You for nothing John Prescott who foisted these pains in the rear on us.

For a rather big general problem read here.

The one issue I am angry about right now is that at least with Worcester Bosh Boilers you cannot turn the Hot Water off if you have the heating on.

I can have the Hot Water on its own if I do not have the Heating on. O.K. in Summer I suppose.

but if the heating is on, Hot Water is given priority in any event so this just has to be going as well.

There is just the missus and I so Hot Water out of the tap is not required all day long. Cup of Tea...put the Kettle on.

Money is obviously wasted if water is heated and not used as and when we need it.

All Worcester say is that is how they are built and meant to be.

Meanwhile I cannot exactly quantify how much cash this is costing over time, but with the price of Heating Oil it is probably quite a lot over the year.

This is similar I guess with the latest light bulb fiasco foisted on us by the EU and Tony Blair.

Does anyone else have this problem who has a Condensing Boiler...or is it just Worcester Bosch?

Provided that your tank is well lagged, you will not lose much through having the water heating on all day even if you don't use the hot water as all you will lose is the energy required to replace the heat that has escaped from the tank.

And, provided the tank is not in the attic, that lost heat will be heating your house anyway.

There is no way that you are losing more through this than you are saving by having a condensing boiler.

The Tank is actually part of the boiler. The boiler is in the Garage so no part of any warmth coming from the Boiler is helping the house out.

That Hot Water being constantly kept hot when not needed just has to be both costly and wasteful.

Do you keep your Hot Water on all day and night then?

If so perhaps you are in a Money Saving Forum under false pretenses?

How are you a serious Money Saving Fan then?

I did say: "Provided that your tank is well lagged".

If it isn't - and particularly if it's outside the heated area then nothing I said applies.

No, I don't. But if I did have the hot water on all the time the heating was on - certainly not 24 hours a day - very little would change because the tank is both well lagged and, anyway, any heat escaping would simply heat the house and reduce the heat required from the radiators.

I have a Worcester Bosch boiler. It has an Eco mode, where you can stop it storing hot water - the only time it then heats water is when the hot tap is turned on. If you only use the cold tap, no water is heated.

Does your model have the same feature?

As an aside:

NO INEFFICIENT AND COSTLY WIND FARMS
NO UGLY PYLONS
NO BACK UP POWER STATIONS
NO BLIGHT ON THE COUNTRYSIDE
NO DESTROYING TOURISM AND JOBS
NO RIP OFF CARBON CREDIT CHARGES:mad:

How exactly do you think electricity should be generated then?

Hello. I actually have a Worcester Greenstar Heatslave 18/25 (Pretty powerful) Floor Standing, Oil Fired Condensing Combination Boiler.

I wish mine worked as yours but it does not. No Eco mode on a Condensing Boiler I do not think.

"Only heats the water when the hot tap is turned on?" do you mean a combi?

garethgas

No, its a thermal store not a combi.

Yes, it's a condensing combi boiler - a Worcester Bosch Greenstar. It has two modes; normal (in which a small internal tank of hot water is maintained, so when you turn on the hot tap this is sent immediately) and Eco (no tank, so it takes slightly longer for hot water at the tap).

It seems the OPs boiler doesn't have this feature, which is unfortunate. I guess that's a limitation of that boiler though, not condensing boilers in general.

Is the internal tank properly insulated?

If it is then OP does not have that much to worry about.

If it isn't then it could lose a lot of heat, particularly if the boiler is in an otherwise unheated area.

Mine isn't. My hot water tank is in the airing cupboard and no heat at all comes from my boiler when it's operating. (It's in my utility area so I can tell.)
