Boiler Help Required - Glow-worm Space Saver Mk2

[Dave547]

Hi Folks,

I've just moved into a new house with a Glow-worm Space Save Mk2 boiler. Unfortunately, I don't have a user manual, and can't find one online.

The heating & hot water both work fine, as does the timer control. (Control is a Randall 102) Looking at my gas meter, I'm using approx 3 cubic metres an hour, even with the control turned off. However, I seem to have hot water all the time, so I'm guessing the boiler is keeping my water hot all the time. I hate the idea of burning gas to keep water hot overnight and when I'm out through the day.

Is there a way to set it so the only time any hot water is produced (for heating or from the taps) is during the time I set it to come on?

Any advice is greatly appreciated!!

boiler shouldnt run if the programmer is off you need to set the times with the blue and red tappets on the dial

 

[Dave547]

That's what I thought. I even turned the timer off by its switch, and the wall switch to make sure it was all off.

There's a thermostat under the panel which I've set to minimum - would the thermostat determine the temp of the water coming out of the taps?

is it on constant on the programmer

 

[Dave547]

The radiators are controllable, (only come on when I set them to) but the water seems to be on constant.

sorry 102 doesnt have a constant mode if all the power is off could be a boiler problem you need a gas safe engineer to check it out

3 cubic metres per hour?

That is around 32kw! Where is all the heat going if only doing
hot water? You need to get a registered gas fitter to look at
this as soon as possible.

Meanwhile it would be best to turn of the power to the appliance
for safety reasons.

seems like a random question do you have an electric immersion heater? is the gas meter dials turning when the boiler is off?

I may have misread, but will definitely get someone to look at it.

I have an electric immersion, but haven't had it on for any length of time yet. I can try turning the boiler off completely (pilot light as well) if that would help to eliminate anything?

could be the lug on the randel they are prone to breaking off and not switching of the timer.

 

[tom609]

if you have no other gas appliances turn off at the meter though would reccomending turning off at the meter anyway in case of a boiler problem

Just been googling gas meters, and I think I understood the reading wrong!

The reading went from 5345,184 to 5345,272 (where the last 3 numbers are in the red box)

I take it this means I've used 0.088 metres cubed?

is this over two minuites or 60?

 

[tom609]

over what period of time did you take the reading

 

[Dave547]

Sorry, that's over a 3 hour period, so that's about 0.03 cubic metres per hour.

I took another reading 3 hours later, and the amount used was at the same rate.

is the burner lit on the boiler or just the pilot, when power supply is off and the thermostat is turned off at the boiler

 

[Dave547]

Pilot light is lit, but the burner isn't. (When I switch it on at the control, I can hear the burner light up, and then go off when I turn it off)

The power supply I've switched off is the wall switch nest to the timer control. I'm assuming this only switches off the timer, rather than electricity going to the boiler?

Adjusting the thermostat hasn't had any effect on the pilot.

 

[tom609]

if the burner goes out completly when you switch off the thermostat on the boiler then thats ok relatively speaking if the burner is not lit at any other time apart from when the timer is calling for heat thats ok too the pilot is alwayson asits a permanent pilot

If this over 3 hrs then this will be the Permanent pilot light if it has one. Sounds to me you just need to get someone out to give you some reassurance and check the controls are ok. Where about's are you in the country maybe someone on here is near you.
